To ensure the safety of yourself and others, please observe the

following precautions:

Ni-cd Battery

Charge the Batteries! Don't forget to recharge the batteries before each flying

session. Plug in the charger that comes in this system and hook up the transmitter

and airborne batteries the day before a planned flying session. A low battery will

soon die causing loss of control and a crash. When you begin your flying session,

reset your 8Usuper’s built-in timer, and during the session pay attention to the

duration of usage.

Quit flying long before your batteries become low on charge. On-field

charging of your batteries with a field charger is not recommended. Overcharging

the Ni-Cd batteries with a fast-charger may cause overheating and a premature failure.

Flying field

We recommend that you fly at a recognized model airplane flying field. You can

find model clubs and fields by asking your nearest hobby dealer, or contacting the

Academy of Model Aeronautics.

Always pay particular attention to the flying field’s rules, as well as the

presence and location of spectators, the wind direction, and any obstacles on the

field. Be very careful flying in areas near power lines, tall buildings, or

communication facilities as there may be radio interference in their vicinity.

If you must fly away from a club field, be sure there are no other modelers flying

within a two-mile range, or you may lose control of your aircraft.

On the flying field

Before flying, be sure that the frequency you intend to fly with is not in use,

and secure any frequency control device (pin, tag, etc.) for that frequency before

turning on your transmitter. Never believe that it’s possible to fly two or more

models on the same frequency at the same time. Even though there are

different types of modulation (AM, FM, PCM), only one model may be flown on

a single frequency.

To prevent possible damage to your radio gear, turn the power switches on and off in

the proper sequence, given below.

When you are ready to fly your model, move the throttle stick to the low

speed position, or do whatever is necessary to command your motor NOT to run.

Then, you may turn on the transmitter power followed by the receiver power.

When you have finished flying, begin by turning off the receiver power, then

turn off the transmitter power. If you do not follow these procedures, you may

damage your servos or control surfaces, flood your motor, or in the case of electric-

powered models, the motor may unexpectedly turn on and cause a severe injury.

We recommend that you range-check your system before each flying session.

Before starting the engine, fully extend the transmitter antenna, power up

the transmitter and receiver, and check to be sure that the servos follow the

movement of the sticks. If a servo operates abnormally, don’t attempt to fly until

you determine the cause of the problem.

Finally, before starting the engine, be sure to check that the transmitter

model memory is correct for the chosen model, and (for PCM receivers only)

that the fail safe system functions properly when the transmitter is shut off.

While you’re getting ready to fly, if you place your transmitter on the

ground, be sure that the wind won’t tip it over. If it is knocked over, the throttle

stick may be accidentally moved causing the engine to race.

Before taxiing, be sure to extend the transmitter antenna to its full length.

A collapsed antenna will reduce your flying range and cause a loss of control. It is a

good idea to avoid pointing the transmitter antenna directly at the model, since the

signal is weakest in that direction.

Don’t fly in the rain! Water or moisture may enter the transmitter through the

antenna or stick openings and cause erratic operation or loss of control. If you must

fly in wet weather during a contest, be sure to cover your transmitter with a plastic

bag or waterproof barrier.

The versatile FP-T8UAFS/T8UAPS PCM1024 multi-function 8-channel transmitter may

be used with any Futaba PCM1024 receiver! In addition, your system will work with Futaba

FM/PPM receivers when you select the FM transmission option. The large liquid-crystal

display panel allows rapid data input into its easy-to-read LCD display. To allow efficient

programming, all of the transmitter’s functions have been separated into Basic Menu and

Advanced Menu functions.

The 8UA transmitter has electronic trims so that rapid yet precise trim adjustment is

possible while flying. These exclusive trims are designed to that when the trim lever is

activated, trim movement accelerates, and in addition, each trim’s sensitivity may be

programmed to match the model or control. For convenience, the location of the trim is

constantly displayed on the LCD panel.

The 8UA system comes complete with programming for ACRO (aircraft),

HELISWH1/SWH2/SWH4/SR-3/SN-3 (helicopter), or GLID1FLP/2FLP (sailplane) mixing

and can accommodate virtually any model configuration. The compact, ergonomically-

designed transmitter holds completely independent memories for eight different models.

[For modelers requiring additional storage, memory for another eight models can be added

using the DP16K (available separately). You may also easily transfer your model

data to another T8UA/T8UH transmitter plugging your into the other transmitter.

The data pack does not require any battery backup and can be stored indefinitely.]

The 8UA features a new stick design which provides an improved feel. The sticks’

length and tension may be adjusted. Switches are provided for dual rate (D/R),

programmable mixers (PMIX), and other functions, and the location of the switches can be

changed electronically to suit your own preferences. For those learning to fly, the

transmitter has “buddy-box” capability and the training channels can be selected by the

instructor. [The trainer cord is sold separately.]

Standard programming features include servo reversing for all channels, ATV on all

channels, dual rates, exponential, throttle cut, electronic subtrim on all channels, and fail safe

on all channels (PCM transmission only). An alphabetic name may be used for each model

stored in the eight model memories.

The 8UA features a number of special mixing features applicable to all types of flying

models. For aircraft, there are extensive preprogrammed mixing features: aileron differential,

flaperon, V-tail, elevon, airbrake (with delayed elevator), elevator→flap, snap roll in 4

directions, throttle→needle (with acceleration), idle-down, engine starting, and second aileron

switching. Helicopter features include throttle and pitch curve settings, hovering pitch and

throttle, revolution mixing, delay, offset, invert, throttle needle, gyro mixing, and governor

mixing. Special sailplane features for single and dual flap servos include flap→aileron,

aileron→flap, elevator→flap, aileron differential, butterfly mixing, camber control, and start

(launch) and speed presets.

If you plan to fly sailplanes extensively, you may wish to buy the 8UH (helicopter)

system, since its three-position switch is on the top left of the transmitter, while for the 8UA

(aircraft) system, the three-position switch is on the top right.

The R148 eight-channel receiver included with your system is a high-sensitivity narrow-

band, dual conversion receiver. Not much larger than a pack of gum, it weighs just 1.07 oz

yet provides superior range and performance.

The S3001 servo includes a ball bearing and provides 60° of travel in a rapid 0.22 second,

along with a rated torque of 41.7 oz-in. The S148 servo is a standard servo with similar

torque rating and transit speed in a slightly lighter package.

Specifications and ratings are subject to change without notice.

To remove, press the tabs together

and gently pull rearwards.

To install, line up the connector pins with

the socket in the rear of the module and

gently snap into position.

1. Connect the transmitter charging jack and airborne Ni-Cd batteries to the

transmitter and receiver connectors of the charger.

2. Plug the charger into a wall socket.

3. Check that the charger LED lights. The batteries should be left on charge for

about 15 hours when recharging the standard NR-4J and NT8S600B Ni-Cd batteries.

Only charge the batteries with the charger supplied with your system. The

use of a fast charger may damage the batteries by overheating and dramatically

reduce their lifetime.

You should fully discharge your system’s batteries periodically to prevent a

condition called “memory.” For example, if you only make two flights each

session, or you regularly use only a small amount of the batteries’ capacity, the

memory effect can reduce the actual capacity even if the battery is fully charged. You

can cycle your batteries with a commercial cycling unit, or by leaving the system on

and exercising the servos by moving the transmitter sticks. Cycling should be done

every four to eight weeks, even during the winter or periods of long storage. Keep

track of the batteries’ capacity during cycling; if there is a noticeable change, you

may need to replace the batteries.

You may change the length of the control sticks to

make your transmitter more comfortable to hold and

operate. To lengthen or shorten your transmitter’s

sticks, first unlock the stick tip by holding locking

piece B and turning stick tip A counterclockwise.

Next, move the locking piece B up or down (to lengthen or shorten). When the

length feels comfortable, lock the position by turning locking piece B

counterclockwise.

You may adjust the stick tension of your sticks to provide the “feel” that you like

for flying. To adjust your springs, you’ll have to remove the rear case of the

transmitter. First, pop off the battery cover on the rear of the transmitter. Next,

unplug the battery wire, and remove the battery and RF module from the transmitter.

While you’re removing the RF module, pay attention to the location of the pins that

plug into the back of the module. Next, using a screwdriver, remove the four screws

that hold the transmitter’s rear cover into position, and put them in a safe place.

Gently ease off the transmitter’s rear cover. Now you’ll see the view shown in the

figure below.

Using a small screwdriver, rotate the adjusting screw for each stick for the desired

spring tension. The tension increases when the adjusting screw is turned clockwise,

and decreases for counterclockwise motion.

When you are satisfied with the spring tensions, you may close the transmitter.

Check that the upper printed circuit board is on its locating pins, then very carefully

reinstall the rear cover being careful thread the RF module connector pins through the

hole in the case and not to bend them. When the cover is properly in place, tighten

the four screws.

Press the plus (+) or minus (–)

key to change the mode number as desired.

You’ll see the effect of you changes when you next turn on your transmitter. In

some cases, you’ll have to swap the throttle detent mechanism with the elevator

centering mechanism. This can be done by Futaba.

The diagram below shows the default connections in the ACRO mode.

FP-R148

DO NOT cut or coil the receiver antenna wire. Secure a portion to the top of the

vertical fin, and let the excess length trail behind the aircraft.

When you insert servo or battery connectors into the receiver, note that each plastic

housing has an alignment tab. Be sure the alignment tab is oriented properly before

inserting the connector. To remove a connector from the receiver, pull on the

connector housing rather than the wires.

If your aileron servo (or others) are too far to plug into the receiver, use an aileron

extension cord to extend the length of the servo lead. Additional extension cords of

varying lengths are available from your hobby dealer or Futaba.

While you are installing the battery, receiver, and servos into your

model’s fuselage, please pay attention to the following guidelines:

Wood screw

Rubber grommet

Brass eyelet

Servo mount

or rail

Use the supplied rubber grommets when

you mount each servo. Be sure not to overtighten

the screws. If any portion of the servo case directly

contacts the fuselage or the servo rails, the rubber

grommets will not attenuate vibration, which can

cause mechanical wear and servo failure.

Once you have installed the servos, operate each one over its full travel and

check that the pushrod and output arms do not bind or collide with each other,

even at extreme trim settings. Check to see that each control linkage does not

require undue force to move (if you hear a servo buzzing when there is no transmitter

control motion, most likely there is too much friction in the control or pushrod).

Even though the servo will tolerate loads, any unnecessary load applied to the servo

arm will drain the battery pack quickly.

When you are ready to install the switch harness, remove the switch cover and

use it as a template to cut screw holes and a rectangular hole slightly larger than the

full stroke of the switch. Choose a switch location on the opposite side of the

fuselage from the engine exhaust pipe, and pick a location so that it can’t be

inadvertently turned on or off during handling or storage. Install the switch so that it

moves without restriction and “snaps” from ON to OFF and vice versa.

It is normal for the receiver antenna to be longer than the fuselage.

DO NOT cut it or fold it back on itself – cutting or folding changes the

electrical length of the antenna and may reduce range. Secure the antenna to the top

of the vertical fin, and let the excess wire length trail behind. You may run the

antenna inside of a non-metallic housing within the fuselage, but range may suffer if

the antenna is located near metal pushrods or cables. Be sure to perform a range

check before flying.

The receiver contains precision electronic parts. Be sure to avoid vibration,

shock, and temperature extremes.

For protection, wrap the receiver in foam rubber or other vibration-

absorbing materials. It’s also a good idea to waterproof the receiver by placing it

in a plastic bag and securing the open end of the bag with a rubber band before

wrapping it with foam. If you accidentally get moisture inside the receiver, you may

experience intermittent operation or a crash.

The following frequencies and channel numbers may be used for flying aircraft in the

United States:

72 MHz band

50 MHz Band (Amateur license

required)

Installing your frequency number

indicator:

It’s very important that you

display your transmitting channel

number at all times. To install your

indicator, peel off the channel number’s

backing sheet, and carefully stick the

numbers to both sides of the number

holder. Now you can snap the number

holder onto the lower portion of the

antenna as shown in the figure – use the

clip that fits more snugly on your

antenna. You may wish to cut off the

other, unused clip on the indicator.

When you first turn on your transmitter, a confirmation beep sounds, and the screen

shown below appears. Before flying, or even starting the engine, BE SURE that the

model name appearing on the display matches the model that you are about to fly! If

you don’t, servos may be reversed, and travels and trims will be wrong, leading to an

immediate crash.

An alarm or error indication may appear on the display of your transmitter for several reasons,

including when the transmitter power switch is turned on, when the battery voltage is low, and

several others. Each display has a unique sound associated with it, as described below.

Warning sound: Beep beep beep beep

(repeated)

The BACKUP ERROR warning occurs when the

transmitter memory is lost for any reason. If this

occurs, all of the data will be reset when the power is

turned on again.

DO NOT FLY when this message is displayed

– all programming has been erased and is not

available. Return your transmitter to Futaba for

service.

Warning sound: Beep beep beep beep beep

(repeated 3 times)

The MODEL SELECTION warning is displayed

when the transmitter attempts to load a model

memory from a memory module that is not currently

plugged into the transmitter. When this occurs,

model No. 01 is automatically loaded.

Do not fly until the proper model is loaded

into memory!

Reinsert the memory module, and

recall the desired setup using the model select

function.

Warning sound: Beep beep beep — (beeping

does not stop until transmitter is turned off)

The LOW BATTERY warning is displayed when

the transmitter battery voltage drops below 8.5V.

LAND YOUR MODEL AS SOON AS POSSIBLE

BEFORE LOSS OF CONTROL DUE TO A DEAD

BATTERY.

Warning sound: beep beep beep beep beep

space (repeated)

The MIXER ALERT warning is displayed to

alert you whenever you turn on the transmitter with

any of the mixing switches active. This warning

will disappear when the offending switch or control is

deactivated. Switches for which warnings will be

issued at power-up are listed below:

ACRO: Throttle cut, idle-down, snap roll, airbrake

GLID: Butterfly, throttle cut, idle-down

HELI: Throttle cut, inverted, throttle hold, idle-up

(Operation when switch OFF does not stop the mixing warning)

When the warning does not stop even when the mixing switch indicated by the warning

display on the screen is turned off, the functions described above probably use the same

switch and the OFF direction setting is reversed. In short, one of the mixings described above

is not in the OFF state.

In this case, reset the warning display by pressing (+)/(-) keys simultaneously. Then change

one of the switch settings of the mixings duplicated at one switch.

This warning appears when an [optional]

CAMPac

memory module is used in the transmitter for the first

time. When the Plus (+)

DATA INPUT

key is

pressed, initialization of the module begins, after

which the memory module can be used. Once the

module is initialized, the display will not appear

again.

Warning sound: A single beep

This single beep lets you know that the RF module is

not installed in the transmitter.

AIRCRAFT SETUP INSTRUCTIONS (GENERAL 120 CLASS STUNT PLANE)

The aircraft setup procedure presented below

uses a F3A-class model as an example. You may

use a similar procedure to set up your own model,

but your setting’s numbers and percentages will

probably be different.

1. Enter the Model Select menu (MODEL) by

pressing the two BASIC keys, then pressing one

of the MODE keys until “MODEL” appears.

Press the right (>)

key to get to the model

select function (SEL) and choose a vacant model

memory with the plus (+) and minus (–) keys.

Select it by pressing both the

keys at

once. The following instructions refer to

memory #5.

2. Press the right (>) key twice to get to

the model name function (NAME, p. 37). Use

the

and keys to spell out the

name that you wish to appear on the screen, one

letter at a time.

3. Enter the Parameter (PARA, p. 31) menu by

pressing the down MODE key twice. Use the

left (<)

key to select the model type

(TYP) function and verify that ACRO (aircraft) is

selected. (If it isn’t, select ACRO by pressing the

plus or minus

keys until it appears,

then pressing both

keys to select it.)

WARNING: selecting a different model type will

erase the settings in the model memory. BE

SURE you’re in the correct model memory before

selecting a new model type.

If necessary, go to the modulation (MOD, p.

34) menu to select the proper mode of

transmission (F is for FM/PPM transmission, and

C is for PCM). This should be set to match your

receiver. If you make a change, it won’t take

effect until you cycle the power off and on again.

4. Next, turn on the Flaperon function (FLPRON,

p. 45) in the Advance Menu.

To do this, press both ADVANCE buttons

simultaneously, then press the MODE button until

“FLPRON” appears in the display. Activate by

pressing the plus (+)

key (“ON” should

appear flashing in the display.

Connect the right aileron servo to receiver CH1

and the left aileron servo to receiver CH6.

Note that you can get differential by adjusting

the up and down motion of the two servos in the

FLPRON menu. If you don’t need the flap

effect, you can use the AI-DIFF menu (and plug

the servo into the receiver CH7 output.

5. Check that each servo moves the proper

direction. The aileron servos should move in

opposite directions for aileron stick motion, and

the same direction for flap control. If not, use the

Reversing function (REVERS, p. 30) in the Basic

Menu to set the proper throw directions for each

servo. Also check elevator, rudder, throttle, gear,

and any other servos.

6. Set the basic travels with the ATV function in

the Basic Menu (ATV, p. 26).

Aileron settings: the left and right aileron travel

should be limited to roughly 9/16” (14-15

mm). If necessary, adjust CH1 and CH6

with the ATV function. Choose a location on

the servo arm so that the throw is adjusted in

the 90-100% range.

Elevator setting: adjust the elevator travel to

roughly 9/16” (15 mm) with the ATV

function.

Rudder setting: adjust the rudder travel to roughly

45 degrees in the left and right directions with

the ATV function.

7. Dual Rate setting (D/R, p. 26)

Adjust the servo motions with the D/R function

(in the Basic menu).

Aileron Dual Rates: adjust the aileron travel to

roughly 7/16” (11 mm). You may also wish

to adjust EXP so that its rate is -20 to -30% to

soften things around neutral.

Elevator D/R: adjust the up side to 15/32” (12

mm) and the down side to 17/32” (13 mm).

EXP should be -15 to -20%.

Rudder: adjust the left and right travel to 40 to 45

degrees. EXP should be about -20%.

8. Airbrake (ABRAKE, Advance menu, p. 47):

an airbrake effect is obtained by raising both

ailerons and adding elevator to trim. This high-

drag configuration assists landings in small

airfields. It is possible to loose some aileron

effectiveness so test the airbrake effect at altitude

before trying it on a landing approach. You

should spend some time fine adjusting the elevator

travel so that there is no trim change with the

application of airbrakes.

The rates may vary considerably for different

models, but for initial settings choose the flap rate

to be (+)50-55% for both CH1 and CH6. The

ELE rate should be set to -7% - -10%.

We recommend that you select the Manual mode.

The default airbrake switch is SW(C), lower

position ON. Move SW(C) to the lower position

and verify its operation.

9. Snap Roll (SNP, p. 50, Advance Menu)

Activate the Snap Roll function by pressing the

plus (+)

key.

Set the deflection rate for each switch position.

Be sure that the direction of motion of each

control is correct.

Aileron: 80 - 100%

Elevator: 90 - 110%

Rudder: 60 - 70%

We recommend that you activate the safety switch.

This stops your model from snap rolling if the

landing gear are not retracted, so you don’t

accidentally snap while taking off or landing.

If your aircraft snaps poorly, increase the

deflection of the elevator and rudder. Note that

some models don’t snap even when the control

deflections are increased. This may caused by

too far forward center of gravity, or by the

characteristics of the airplane.

10. Failsafe settings: we recommend that you set

the Fail Safe function (F/S, p. 29) to move the

throttle to idle if interference is experienced.

Note that the failsafe function only operates in the

PCM transmission mode.

11. Now take advantage of your system’s other

great programming capabilities. You may set

such functions as Throttle→Needle and Throttle

delay to improve engine response, and couple

elevator to flaps for tighter corners in the elevator-

to-flap mixer (ELE→FL, p. 48). You may want

to use programmable mixers to get rid of

unwanted tendencies (for example, pitching up

during knife-edge flight. Finally, if you have

dual elevator servos, you can turn on the Ailevator

function (ALVATR, p. 49) to increase roll

authority in low-speed maneuvers. The sky’s the

limit — enjoy!

The following chart may be used to systematically set up and trim a model for straight flight

and aerobatic maneuvers. Please note that for best results, trimming should be done in near-

calm conditions. Before you decide to make a change, be sure to try the test several times

before making adjustments. If any changes are made, go back through the previous steps

and verify that they are not also affected. If they are, make further adjustments as necessary.

The ATV function is used to set the travel of each servo in both directions. At a

100% setting, the throw of the servo is approximately 40° for channels 1 – 4 and

approximately 55° for channels 5 – 8. Reducing the percentage settings reduces the

total servo throw in that direction. The ATV menus should be set to prevent any

servo binding at extreme travel.

Exponential settings may be used to change the response curve of the servos to

make flying more pleasant. You can make the servo movement less or more

sensitive around neutral for aileron, elevator, throttle, and rudder. It can also be set

for each side of the dual rate switches. Negative exponential (–) makes the servo

movement around the stick neutral less sensitive and positive (+) makes the servo

movement more sensitive.

For throttle, exponential is applied from the end of travel rather than for neutral

like the other controls. When the "–" side is increased, the idle sensitivity decreases

and the high throttle sensitivity increases. This is best understood by experimenting

with a servo.

• The "SW-C C/DN" display indicates that both the switch C

CENTER and DOWN positions activate the IDL-DN

function to lower the idling speed.

• The "SW-G DOWN" display indicates that the G switch in

the DOWN position activates the IDL-DN function.

• The "SW-G UP" display indicates that the G switch in its

UP position activates the IDL-DN function.

Normally, a value of about 10- 20% is suitable. Secure the fuselage,

and while running the engine, set the throttle stick to idle. Adjust the

idle down rate while flipping the switch ON and OFF.

The Fail Safe function is used to prescribe what the PCM receiver will do in the

event radio interference is received. In this menu, you may select from one of two

options of operation for each channel. The "NORM" (normal) setting holds the

servo in its last commanded position, while the "F/S" (Fail Safe) function moves each

servo to a predetermined position. The default setting is NORM (normal) for all

channels.

The use of the fail safe function is recommended from the standpoint of safety.

You may wish to set the throttle channel so that the engine idles when there’s

interference. This may give enough time to fly away from and recover from the

radio interference. If you choose to specify a failsafe setting, the fail safe data are

automatically transmitted once each minute.

Battery Failsafe

Your system provides a second safety function called Battery Failsafe. When the

airborne battery voltage drops below approximately 3.8V, the battery fail safe function moves

the throttle to a predetermined position.

When the battery failsafe function is activated, your engine will move to idle (if you

haven’t set a position) or a preset position. You should immediately land. You may

temporarily reset the failsafe function by moving the throttle stick to idle, at which time you’ll

have about 30 seconds of throttle control before the battery function reactivates.

The Trainer function is used to train novice pilots using an optional trainer cord connecting

two transmitters. The instructor may choose that all channels be controlled by the student, or

that certain designated channels be operated by the student and the remainder by the instructor.

Pulling on Switch F allows the student to control the selected channels on the model. You

may use your 8UA transmitter with any transmitter of the SKYSPORT, Super 7, or 1024Z

series of transmitters. Simply plug the optional trainer cord (sold separately) into the trainer

connection on each transmitter. Note that when the trainer function is active, the snap roll

function is automatically deactivated.

Trainer function operation modes:

"FUNC": When the trainer switch is ON, the channel set to this mode can be

controlled by the student by using the mixing set at the instructor's transmitter.

"OFF": The channel set to this mode cannot be controlled by the student even when

the trainer switch is ON. The set channel can be controlled by the instructor only.

"NORM": When the trainer switch is ON, the channel set to this mode can be

controlled by the student. The set channel is controlled according to the contents set at

the student's transmitter.

Examples:

When the stick channel is set to the "FUNC" mode, helicopter stick operation practice

is possible even with a 4VF transmitter (4 channels for aircraft).

The practice channel matched to the student level can be set to the "NORM" mode

and the other channels can be set to the "OFF" mode and controlled by the instructor.

A few important precautions:

• NEVER turn on the student transmitter power. Collapse the student’s antenna.

• ALWAYS set the student transmitter modulation mode to PPM.

• BE SURE that the student and instructor transmitters have identical trim and control motions.

Verify by switching back and forth while moving the control sticks.

• FULLY extend the instructor’s antenna.

•

Always remove the student transmitter RF module (if it is a module-type transmitter).

travel is restricted.

The recommended procedure is as follows: zero out both the trims (TRIM RSET

menu) and the subtrims (this menu). Next, mount the servo arms and set up your

linkages so that the neutral position of the control surface is as close to where it

should be as possible. Finally, use a small amount of subtrim to make fine

AIRCRAFT (ACRO) ADVANCE MENU FUNCTIONS

The next section of this manual, pages 43 to 51, describe how to use the functions in

Your 8UA system contains seven separate programmable mixers with unique mixing

capabilities. You may use mixing to correct bad tendencies of the aircraft during aerobatics,

and to make operation more pleasant. Besides mixing between arbitrary channels, the mixers

may be linked with the Advance menus in the 8UA. They can also be set to provide fixed

offsets. You may select which switch activates your mixers. The method to be used to

program mixers is given for Mixer #1, but Mixer #2-5 may be programmed in an identical

fashion. Mixer #6-7’s mixing rate can be set with a 5-point curve.

The Link function is used to ‘link’ programmable mixers with other mixing menus. For

example, you might wish to use a PMIX to provide rudder

→

aileron mixing for better knife-

edge flight in a model with flaperons using the Flaperon (FLPRON) mixing function. With

two aileron servos plugged into receiver channels CH1 and CH6, mixing only appears at the

CH1 aileron when rudder is commanded. When the Link function is turned on, this situation

is easily corrected, and mixing is applied to both

CH1 and CH6.

The trim selection option allows you to choose whether the trim from the master also

affects the slave channel. The offset function lets you offset the mixing curve for the slave

channel relative to the master channel, a feature which is handy for mixing with non-centering

functions such as throttle or knobs as the master channel.

Switch selection: you may choose an ON/OFF switch for each of the programmable

mixers from the eight switches A - H. In addition, the throttle stick (CH3) may be used to

urn the programmable mixers ON and OFF. t

The Flaperon mixing function uses two servos to

individually control two ailerons, combining the

aileron function with the flap function. For a flap

effect, the ailerons can be raised and lowered

simultaneously. Of course, aileron function, where

the two controls move in different directions, is also

performed. The up and down travel of the left and

right ailerons can be adjusted independently, so you

can also get a differential effect. Left and right

flap travel can be adjusted individually. You can

combine the Flaperon function with the airbrake

function, to get steep descents without building up

airspeed, which is very convenient for small or

narrow fields. To take advantage of the flaperon

mixing function, you’ll need to connect the right

aileron servo to CH1 (AIL) and the left aileron servo

to CH6 (FLP).

The Flap Trim function is used to specify the amount of flap travel (or camber, if on a

sailplane setup). If flaperon (FLPRON) mixing is active, FLAPTRM is automatically turned

on. You should match the travel of both flaps before using this function to set the total

amount of flap throw. The amount depends on the model, but for sailplanes a small amount

(less than 10%) is preferred, since too much camber produces excessive drag. Don’t use

more than about 1/16” travel up or down (some airfoils, such as the RG-15, should be flown

with NO reflex).

The ABRAKE function simultaneously drops the flaps and moves the elevator, and may

be used to make steep descents or limit airspeed in dives. Airbrakes can be activated in a

proportional manner by moving the throttle stick, or you may choose to move all the controls

to the defined positions by flipping switch C. If you choose to operate it by throttle stick

motion, you’ll need to set the stick position for it to be activated. You can suppress sudden

changes in your model’s attitude when airbrake is activated by setting the delay ("DLY") item,

which slows down the elevator response.

When the FLPRON function has been selected, the travel of the ailerons when the

airbrake is operated can be independently adjusted for the servos plugged into CH1 and CH6.

When AI-DIFF function is used, the travel for CH1 and CH7 may be adjusted. Normally

both ailerons are raised in the airbrake mode, and the elevator motion is selected to maintain

rim when the ailerons rise. t

Setting up V-Tail mixing

Be sure to move the elevator and rudder sticks continually while checking the servo motions. If a large value of

The pages in the glider section describe the additional special mixing

functions that only are available when the two glider (GLID1FLP, GLID2FLP) model

types are selected. The GLID1FLP menu is intended for sailplanes with one or two

aileron servos, and a single flap servo (or two connected with a y-connector), while

the -2FLP configuration is for dual flap servos that can act oppositely as ailerons.

Note that for some aerobatic and slope gliders, the ACRO menus may be more

appropriate to use, as they provide snap rolls.

For an explanation of the other Advance Menu functions available in the GLID

menus, refer to the aircraft (ACRO) Advance Menu section, p. 43 to 51.

If you wish to have the three-position switch controlling Normal, Start, and Speed

on the left-hand side of the transmitter, you should purchase the 8UH Helicopter

system. The 8UA system places it on the right-hand side.

CURRENT MODEL MEMORY WILL BE

ERASED! (The other seven memories will not

be affected.)

3. Do not worry that the servos may not be

moving the proper direction now. We will first

activate all the special mixes necessary, and later

go to the reverse menu to correct any reversed

servo responses (if necessary).

Press the

buttons to get to the Advance

Menus. This is where are the sailplane-specific

mixers are located. Press either of the

keys

to get to the aileron differential (AI-DIF) settings

menu. Activate this mode by pressing the plus

(+)

key (the ‘ ’ symbol will be

flashing). This makes the second aileron servo

(CH7) operate. Ignore the number settings for

now.

4. Move to Aileron→Flap menu (AIL-FL, p 61).

Activate it by pressing the Plus (+)

key

(‘

’ should be flashing). Use the Right (>)

key to get the left-hand number flashing,

then use the plus (+)

key to set a value

of 50%. Move the aileron stick to get the other

number flashing, and set to the same number. You

can increase this setting later if you need more

maneuverability, such as for a slope racer or F3B

model.

Now you may choose whether you want this mix

always on or switchable. By hitting the Right (>)

key, you will see a display indicating

Switch E controls this function, and the setting of

the switch. NULL means always on, UP means

on when Switch E is up, and DOWN means on

when Switch E is down. We recommend

leaving it in the NULL position; you can change

the switch setting by pressing the (+) or (–)

keys.

5. If your model has a V-tail, go to the V-TAIL

menu (p. 41) and activate it. This will make the

elevator and rudder commands mix to the two tail

surfaces. Leave the settings as is for now.

6. Now move the aileron stick to the left. You

should see your model’s servos deflect as shown

in the rear view below. The Right aileron and

flap should move down, and the Left aileron and

flap should go up. If the wing servos move as

specified, you can continue.

REAR VIEW OF MODEL WITH LEFT AILERON COMMAND

Reverse any of CH1, 5, 6, and 7 by moving to the

appropriate channel number with the right or left

keys, then pressing the minus (–) or Plus

(+) key to reverse or unreverse the

channel. Be sure you get the aileron response in

the picture.

Next, move the elevator stick and be sure that the

elevator moves the correct directions. Reverse

CH 2 if necessary. Similarly check the response

of the rudder (CH4). If you have a V-tail, you

should get the following response for rudder and

elevator commands:

Up elevator command Left Rudder command

7. Double-check to make sure all the servos

move the correct way! Then, go to the ATV

menu and specify the maximum servo throws

while moving all the controls. Spend some time

getting the correct motions in this step.

8. Move to the flap→aileron (FLP→AI, p. 60)

menu, and activate by pressing the Plus (+)

key. Use a setting of 100% so the motion

of all four wing servos is the same with flap and

aileron horns that are the same length. If the horn

lengths differ (hopefully in pairs) you can use a

number either greater or less than 100%

depending on the length ratio. The camber

changing is done by turning the leftmost knob on

the top center of the transmitter (CH. 6 flap trim

knob).

9. To set the amount of camber-changing across

the wing, go to the flap trim menu (FLPTRM, p.

39) and activate it by pressing the Plus (+)

key. Set it to a small number (about 5%),

or set it to zero if you want no camber-changing

(this may be changed later for more travel). For

cruising, you'll want no droop at all, but for slow-

speed thermalling, you may want to droop the

trailing edge a bit. Use the flap trim setting to get

the desired amount of camber. No more that

about 1/8" (3 mm) is all that is needed for most

models.

Note that the motion dictated by the Camber knob

(CH. 6 flap trim knob) goes into both positive and

negative camber from the neutral point, unless

you set the F→A offset (see previous step). Also,

note that if you don’t set a small number or leave

it inhibited (its default condition), you get HUGE

motion of the trailing edge. You can set the

approximate neutral point by matching the notch

on the front of the knob with the slot in the knob

holder.

10. Put the camber knob (CH. 6 flap trim knob,

on the top left of the transmitter) where you want

it to be for normal flight, and make sure that the

travel you desire is the right direction from that

point. Be sure to center all of the trims, and get

all of the servo arms to be near neutral. Use the

clevises to get as close as you can. This way you

won't run out of subtrim authority. Now set all

the subtrims (SUBTRM, p. 39) to the desired

neutral locations.

You can set the neutrals for the ailerons and flaps

by using the foam wing beds or matching up with

the rest of the wing. Don’t use the fuselage

airfoil (if any) as these are often not aligned

properly. Set the elevator incidence per the

plans/instructions, and center the rudder.

11. Go back to differential (AI-DIF) and set to

get more 'up' throw than 'down' on the ailerons.

For starters, use a down travel of about 50% of the

up travel. Your model may have different plus

and minus signs depending on the servo

orientations. Note that you set the right aileron’s

travel in both directions (move stick to change

flashing display), then go to the left aileron’s

menu and repeat inputting values.

CH 1 (right) aileron:

Right aileron down travel Right aileron up travel

CH 7 (left) aileron:

Left aileron up travel

Left aileron down travel

12. Set up the butterfly (also referred to as

“crow”) function for glide path control and precise

spot landings. The ailerons go up and the flaps

drop with movement of the throttle stick. Turn

on the BFLY function (p. 59) by pressing the Plus

(+)

KEY. The ‘ ’ display will be

flashing unless switch A is up, then OFF will flash.

First set the Butterfly function activation point.

Hit the Left (<)

key one time to get to

the BFLY offset setting menu. Now move the

throttle stick to where you want the function to

begin. (we recommend having the throttle stick

all the way up for normal flight, and have the

BFLY function “kick in” about 3 clicks from top.

This way, if you accidentally jog the throttle stick

a bit, you won't activate the butterfly function.)

Enter your position by pressing the two

keys simultaneously.

Next, hit the right (>) button until the AIL setting

menu appears. Input a 25% value for the

ailerons. Move the throttle stick and be sure the

ailerons go UP with butterfly (see figure below).

If they don’t, change the sign of the number

you’ve chosen (this may depend on servo

orientation). You'll probably want 1/4 to 1/3 of

aileron travel so you'll have plenty of roll authority

while on approach in full butterfly command.

Notice that you set the throw for both ailerons at

the same time: this is the reason to have identical

control arm lengths and neutral positions.

Hit the (>) CURSOR key once and input the

throw for the flaps. Move the throttle stick and

be sure the flaps DROP with butterfly. If they

don’t, change the sign (this again may depend on

servo orientation). You want as much flap

motion as possible — 90° is great if you can get it.

Like the ailerons, you set both flap offsets at the

same time.

Use zero or very little elevator compensation until

you fly and determine what is needed: if the

model pitches up with butterfly, add down

elevator compensation and vice versa. Make

only small changes in compensation because it

has a big effect on trim. Refer to the sailplane

trimming chart for more details.

13. Set up the START (launch, p.62) preset for

high launches so that the flaps drop slightly lower

than the ailerons to reduce tip-stalling tendencies.

Recommended settings are 30%, 0%, 40%, 40%,

30%. Increase the up-elevator preset in small

increments until the plane launches as steeply as

you like; add down elevator if the model weaves

back and forth or is hard to control (remember to

use the rudder stick, or rudder coupling, during the

launch). A well-trimmed model may actually

have some down elevator mixed in for launching.

Remember that to get the START function to turn

on, you have to flip the START/SPEED switch

(Switch C, over the right-hand stick) to its lower

position.

ON or OFF

Start-Speed

14. You may also set up the speed mode presets

(SPEED, p. 63) for high-speed cruise between

thermals. Reflex (raise) the entire trailing edge

no more than 1/16" (1.5 mm), or you'll gain more

drag than penetration ability. Use no more than 5

or 10% for initial setup.

15. You can add aileron-rudder coupling (1-4

mixing is set up in PMIX-1, p. 43) for coordinated

turns. This setting is highly dependent on the

model configuration. Usually only a small

amount of rudder is needed, especially if a large

amount of differential is present, so start out with

10–15%. Carefully observe the direction of the

fuselage relative to the thermal turn the model is

making. If the nose points towards the inside of

the circle, the coupling is too high, and if it points

towards the outside of the circle, you need more

coupling. When everything is set properly, the

fuselage will be tangent to the thermal turn circle.

Coordinated turn

: fuse

lines up with turn direction

(don't change anything!)

Nose points inside circle

: too

much coupling or differential.

Reduce one or both.

Nose points outside circle

increase coupling and/or

differential

While you are flying, watch for trim changes

during launch and butterfly control actions and set

the compensations to cancel them out.

You can also add other mixing types such as

elevator-to-flap mixing (ELE-FL, p. 48) to make

better pylon turns. You may wish to refer to the

sailplane trimming chart following. Whatever

you do, Enjoy!

The chart on the next page describes the procedures that may be followed when trimming a new

sailplane. The flights for trimming must be made in near-calm conditions, and should be repeated several

times before making adjustments.

One of the most critical steps is the center-of-gravity (CG)/decalage testing (Step 3). Decalage is a

fancy way of describing the relative positions of the wing and horizontal tail. Although the control

neutrals have been set in Step 1, there are differing combinations of elevator trim and CG that produce

stable flight. In general, you get better performance by moving the CG aft, but at the same time you

reduce the stability and make the model more difficult to fly, or make it so that constant attention is

required. Moving the CG aft lessens the download on the model’s tail and in some cases produces an

upload, which means the wing and tail are working together and not against each other as they do with a

forward CG. Many contest flyers use a CG position located between 35 and 40% of the mean wing

chord, which is near the aft limits for stability. A nose-heavy model will be easier to fly but will

lack the performance of the aft-CG model.

You should also set differential and/or rudder coupling carefully. Incorrect settings will result in

needless increased drag, and may be checked fairly easily. If you practice keeping the fuselage straight

while gently rocking the wings back and forth, you’ll learn how to coordinate turns and won’t need

coupled rudder any more. You can also learn about the proper amount of differential or rudder coupling

by studying the figures of the model circling.

Whatever you do, be sure to spend a lot of time trimming your sailplane. If you have a nearby slope,

practice flying on very light days, where you can just barely keep the model airborne. It is under these

conditions that you learn if your model is really trimmed properly.

BFLY — Butterfly Mixing (“Crow”)

The Butterfly mixing function – sometimes called “crow” – is used for glide path control for landing

or for limiting speed when in a dive. Butterfly mixing is controlled with the throttle stick and raises the

ailerons and lowers the flaps (two aileron servos are required, using CH1 and CH7, and the same setting

applies to both, so horns must be identical). Butterfly will work with either one or two flap servos. All

of the servos move linearly with throttle stick motion.

Butterfly mixing can generate a change in pitch, so the elevator may be adjusted to compensate.

Sudden changes in pitch can be suppressed by setting the delay ("DLY") item at the elevator: a 100%

delay means that the elevator takes about two seconds to go to full travel.

Butterfly mixing is manually turned on and off with Switch A. If you turn on the transmitter, and

there’s a beeping sound, it could be your butterfly activation switch is in the ON position.

At the throttle stick “idle” position, butterfly mixing has maximum throws. [If you wish to move

the ATL to the high throttle end, turn on the transmitter holding the two

buttons down (or the two

BASIC or two ADVANCE MENU buttons). You’ll see a display “STICK MODE x.” Press the

lower

button to get to the “TH-FNC” display. Now press the minus (–) key to reverse

the throttle function. You may need to reverse the signs on some mixers after you perform this

operation, which applies to all model memories.]

Flap→aileron mixing is used to

change the camber (the angle of the

ailerons and flaps) over the entire wing,

which produces less drag than just

dropping the flaps by themselves. When

you have Elevator→Flap mixing activated

along with Flap→Aileron mixing, the

entire trailing edge droops or reflexes with

elevator stick motion.

You can program an offset of the flaps

position that provides maximum lift

during launch. Normally the ailerons

and flaps are drooped about 20-30°, with

the flaps drooped slightly more to prevent

tip-stalling on tow. The elevator neutral

can also be offset in order to trim out any

pitch changes caused by the flap and

aileron presets. This function is

activated by flipping switch G to the aft

The following example shows how the T8U may be programmed for a contest helicopter model. The

settings presented here are for a typical model. Your model’s settings are likely to vary from these, but

the procedures given will still be applicable.

1. Memory Selection

Use the Model menu Select function [MSL]

to select a model memory. Choose the

Helicopter Setup using the SEL function from

Model menu. CAUTION: if you select a new

type of model, you’ll loose all the data already in

the model memory. This example assumes

you’re using model memory 2.

2. Name your model using the Model Name

[MNA] function in the model menu.

3. Hook up controls. In the helicopter, hook up

the aileron, elevator, throttle, and rudder servos in

accordance with the model’s instructions or plans.

4. Plug Servos Into Receiver.

CH1 ......................Aileron

CH2 ......................Elevator

CH3 ......................Throttle

CH4 ......................Rudder

CH5 ......................(spare)

CH6 ......................Pitch

CH7 ......................Gyro Sensitivity

CH8 ......................(spare)

5. Set Servo Throw Direction

Check the proper direction of throw for each

servo. Use the Reversing Function [REV] in the

Basic menu to set proper throw directions.

Reverse channels as necessary to correct throws.

Set up the carburetor pushrod so that the carb may

be fully closed to shut off the engine.

6. Servo Travel

Use the ATV command to limit servo travels

to prevent binding.

7. Throttle Cut Setting

After a flight, use the Throttle Cut function to

kill your engine with the trainer switch. There is

no need to fumble with trim, and the idle trim

position will never be lost.

Enter the TH-CUT settings in the Basic menu,

and set the desired switch (we recommend using

the trainer switch F, in the down or momentary

position). Move the throttle stick a few clicks

above idle, then press the (+)/(–) keys

simultaneously to memorize the position. This

makes it so the engine cut function will only

operate when the throttle is below the set point, so

the engine can’t inadvertently be shut off in flight.

Adjust the throttle servo motion so that when

activated, the carburetor is fully closed and there is

no binding in the throttle pushrod.

Normal Flight Programs

Continue within the Basic functions menu to

set up the Normal flight settings (see the menu

structure on p. 65 for more info):

8. Throttle Curve-Normal

Go to the Throttle Curve [TH-CRV NORM]

function. Input the throttle curve to the values

shown in the table below:

Point 1 2 3 4 5

Setting (%) 0 25 45 75 100

You’ll want to set the throttle so it’s about

half open at Point 3. The throttle responds a bit

slower than linear near center, and then the

response rate approaches linear at both ends.

9. Pitch Curve Normal

Move to the pitch curve function [PI-CRV

NORM] from the model menu. For a semi-

symmetrical rotor blade with no twist, the pitch

angle should vary from -4° to +12°. We

recommend setting the hovering pitch to +4.5°.

Move the hovering pitch knob (CH6) and the

hovering throttle knob (CH7) to the center

positions (if these functions are activated in the

Advance Menu, the knobs may be moved in flight

to make adjustments). Next, input pitch curve

data so that the normal pitch used in hovering

varies between -2.5° and +10°.

The pitch angle should be set so that the high

throttle pitch rate is large. This provides high

collective sensitivity to help cope with windy

conditions.

The following values are recommended

starting points for the pitch curve:

Point 1 2 3 4 5

Setting (%) 15 25 55 75 90

Blade pitch -2.0° +4.5° +10°

10. Revolution Mix Setting

Revolution mixing uses the tail rotor to

suppress the torque reaction of the main rotor due

to changes in collective pitch. Call up the

REVOLU NORM Menu. Input the values as

follows:

Point 1 2 3 4 5

Setting (%) -25 -12 0 +12 +25

FLIGHT CONDITION SWITCHING

Your system is already programmed to have

settings for Idle-up 1 [IDL1], Idle-up 2 [IDL2],

and Throttle Hold [HOLD] in addition to the

normal flight condition [NORM]. The menus

for these added flight conditions are contained in

the Advance Menus. Refer to the menu structure

on p. 65 for more info.

The position and ON direction of each flight

condition call switch are set as follows:

•Normal [NORM] – for hovering. Operation

when all switches OFF.

• Idle-up 1 [IDL1] – for 540° stall turns, looping,

rolling stall turns. ON at Switch G center

position

• Idle-up 2 [IDL2] – for rolling aerobatics. ON

at Switch G forward position.

• Throttle Hold [HOLD] – for autorotation. ON

at Switch E forward position.

We recommend that you fly the model and

adjust trims and control responses to your liking in

hover before setting up another flight condition.

To set the condition data for each flight

condition, be sure that you call the appropriate

condition by turning on the correct switch (as

given above). Double-check to be sure that you

are setting the menu you desire.

As mixes are switched on or off, HOLD has

highest priority, followed by IDL2, IDL1, and

NORM.

Idle-Up 1 Settings

The settings for IDL1 conditions are among

those contained in the Advance menus (see the

menu structure on p. 65 for more info).

11. Throttle Curve Setting: move to the TH-

CRV IDL1 menu and activate it. Change the

Idle-up 1 throttle curve points to the values shown

below:

Point 1 2 3 4 5

Setting (%) 57 55 57 75 100

12. Pitch Curve Setting. Move to the PI-CRV

IDL1 menu and activate. The Idle-up 1 pitch

curve should use the same curve as the normal

condition except with the maximum high throttle

pitch angle between 8° to 10°, depending on the

engine used.

Point 1 2 3 4 5

Setting (%) 10 25 50 65 80

Blade pitch -2.5° +4.5° +8°

13. Idle-up 1 Revolution Setting:

These settings are used in 540° stall turns,

looping, and rolling stall turns and are set to be

straight ahead when the model is pointing directly

into or away from the wind. Move to the

REVOLU IDL1 menu and input the following

values:

Point 1 2 3 4 5

Setting (%) -20 -10 0 +10 +20

Idle-Up 2 Settings

The settings for IDL2 conditions are also

among those contained in the Advance menus

(see the menu structure on p. 65).

14. Throttle Curve Setting: move to the TH-

CRV IDL2 menu and activate with the (+) key.

Input the trial throttle curve points as shown

below:

Point 1 2 3 4 5

Setting (%) 60 60 60 75 100

15. Pitch Curve Setting. Step through the

menu to the PI-CRV IDL2 menu. Set the pitch

curve as follows:

Point 1 2 3 4 5

Setting (%) 5 25 50 65 80

Blade pitch -3° +4.5° +8°

16. Idle-up 2 Revolution Setting:

These settings are used in rolls. Move to the

REVOLU IDL2 menu and try out the following

values for the rudder mixing curve:

Point 1 2 3 4 5

Setting (%) -20 -10 0 +10 +20

Throttle Hold Settings

The settings for HOLD conditions, to be used

for Autorotation, are also among those contained

in the Advance menus (see the menu structure on

p. 65).

17. Revolution Throttle Hold Setting:

TH-HLD sets throttle position near idle and

keeps the model pointed straight ahead during

autorotation. Move to the Throttle Hold menu

and activate by pressing the (+) key, then set

switch G to the forward position. Set the hold

position (HLDP) maintain engine idling.

Next, move to the rudder offset setting and set

OFST to keep the tail rotor pitch angle to nearly

0°, since there is no torque. Your numerical

value may vary from those shown.

18. Pitch Curve Setting. Move to the PI-CRV

HOLD menu and activate. During autorotation,

high pitch is used at both the HIGH and LOW

sides, so set the HIGH and LOW rates to their

maximum values: 0 and 100% respectively.

Point 1 2 3 4 5

Setting (%) 0 25 50 65 100

Blade pitch -4° +4.5° +12°

19. Rudder→Throttle Mix Setting

Rudder→Throttle mixing is useful for

hovering eight, nose-in circle, Top Hat, Pirouette,

and other aerobatics. It is normally set up so that

rotor speed is maintained to keep altitude constant

when the rudder stick is operated at half-throttle.

For helis with normal rotor rotation,

commanding right rudder should increase throttle

slightly, while using left rudder should decrease

throttle slightly.

To set this feature, use one of the PMIX

mixers. Press the (+) button to activate it, and set

master = Rudder, slave = Throttle. Input the

value for left at -10%, and the right value to +10%.

Adjust values to suit.

Another use for a programmable mixer

The main rotor’s RPM can decrease due to

increased loads whenever full cyclic control is

used, like when doing a roll. To help keep the

RPM up, you can use a mixer with Master = AIL,

Slave = THR. About 10% mixing is a good

starting point for both directions.

20. Trim Offset Setting

The Trim Offset menus may be adjusted for

Idle-up 1 and Idle-up 2. Aileron, elevator, and

rudder trims may be offset to different positions so

that the model flies straight ahead during normal

flight.

If you find you need some trim offsets in

IDL1 or IDL2, call up whichever of the OFST-1

or OFST-2 menus you need. Recommended

settings for aileron and elevator offsets are small,

from 6% to 10% or as needed.

Rudder offset is set by the Revolution

Throttle Hold function set previously, so is not

included in this menu.

21. Delay Settings

Delay settings are used to prevent sudden

trim changes due to different settings in different

flight conditions. You can set different delays

for aileron, elevator, and rudder. The delays you

set apply to all flight conditions. We recommend

trying very small values for the initial settings, say

5 - 10%. A 25% delay is about a half-second

transit time between neutral settings.

You may use the Hovering Pitch and

Hovering Throttle functions for fine trimming

changes due to humidity, etc.

This concludes the example setup procedure

for helicopters. Be sure to browse through the

pages following this example to see what other

menus are available for helicopters, such as

Hovering Throttle and Pitch knobs, OFST, ACC,

DELAY, and INVERT CROSS. You may use a

mixer to adjust gyro sensitivity, or to enhance

flight capabilities or to correct a response you

don’t like. Again, we recommend you set up and

trim in the Normal flight condition before setting

up the alternate flight modes.

This procedure assumes helicopter is trimmed for hovering. Trimming must be done

in near-calm conditions. Repeat tests several times before making adjustments. If any

changes are made, go back over the previous steps and verify, or further adjust as necessary.

The throttle curve normal function is used to input the normal (NORM) throttle

curve, which is usually not a linear response to throttle stick motion. The normal

throttle curve is the basic throttle curve intended for flight around hover. Together

with the pitch curve (normal), the throttle curve is adjusted for best climb at a fixed

engine RPM. You can program a 5-point throttle curve to get the best engine

response relative to throttle stick motion. Each point of the curve can be adjusted

over a range of 0% to 100%.

There are three throttle curves in your transmitter: normal (NORM), idle-up 1

(IDL1), and idle-up 2 (IDL2), but only the basic normal throttle curve is displayed in

the Basic Menu. The normal curve can be seen and programmed in either the Basic

or Advance Menus, but the others are only accessible in the Advance menu.

The Normal pitch curve function contained in the Basic Menu sets the normal

(NORM) curve. The Normal pitch curve is the basic pitch curve for flight near

hover. Together with the normal throttle curve, the normal pitch curve is adjusted

for best vertical performance at a constant engine speed. You can program the

response over a 5-point curve so that you may choose the best rotor pitch angle

relative to throttle stick movement. Each of the five points can be adjusted over a

0% to 100% range.

The T8U system helicopter programs contain five pitch curves: normal, idle-up 1

(IDL1), idle-up 2 (IDL2), hold (HOLD), and inverted (INVR). The basic normal

pitch curve is the only one displayed in the Basic Menu, but all of the pitch curves can

be viewed in the Advance menu. The Normal curve is the same in both the Advance

and Basic Menus.

The Normal revolution function mixes pitch commands into rudder in order to suppress

the torque generated by changes in the main rotor’s pitch angle. Three are three different

settings of revolution mixing available: normal (NORM), idle-up 1 (IDL1), and idle-up 2

(IDL2). Only normal revolution mixing is displayed on the Basic Menu.

The revolution mixing rate can be input on a 5-point curve. For a clockwise-turning

rotor, the rudder is mixed in the clockwise direction when pitch is increased; for a

counterclockwise-turning rotor, the opposite setting is made. The operating direction setting

is changed by changing the signs of the numbers in the curve from plus (+) to minus (–) and

vice versa:

Clockwise rotation: -50, -25, 0, +25, +50% from low throttle

Counterclockwise rotation: +50, +25, 0, -25, -50% from low throttle

These numbers are the default initial values. You should replace them with the actual

values that work best for your model.

Procedure for adjusting revolution mixing

This procedure assumes that your model is trimmed, and no tail rotor command is needed in

hover.

1. Throttle low-side adjustment (between idle and hovering)

Repeatedly takeoff and hover and return to land. Adjust revolution mixing so that raising

and lowering the throttle does not cause a sudden fuselage heading change. If the nose

points left when landing from hover or when taking off, the low-side mixing rate is too high.

If the nose points in the opposite direction, the mixing rate is too small. Note that the nose

direction may not become stable when taking off if the helicopter is not steady before takeoff,

or if the rotor speed does not rise.

2. Throttle high-side setting (between hovering to high-power climbing)

Apply throttle while hovering to climb and then descend back to hover. Adjust revolution

mixing so that the nose does change heading when the throttle is raised and lowered as in the

low-side adjustment given above.

The Invert function is used to make inverted flight easier. Instead of having to

learn to reverse controls mentally, when switch H is moved forward (and the INVERT

function is activated), the direction of operation of the elevator, rudder, and pitch

servos is reversed. In addition, the pitch servo throw is reduced to about two-thirds

of the normal throw.

Before using the INVERT function, be sure that you helicopter is trimmed for

good normal flight. You’ll need to set up your linkages carefully to use the INVERT

function.

You can adjust the pitch curve and cross position setting when this function is ON

with the inverted pitch curve (PI-CRV, INVR) and inverted cross position (INVERT,

CROSS) menus in the Advance Menu. You can plug your gyro into CH7, and its

sensitivity may be controlled by switch C.

INVERT Function Programming

Turn off the INVERT function (move switch H to the rear position) and select a

servo arm that provides the proper negative and positive pitch angles to allow

autorotation. Hook up the linkage to the servo.

Since the normal flight pitch curve uses NORM, IDL1, IDL2, and HOLD, set up

your helicopter for trimmed flight in hover, forward flight, and autorotation. To

program the inverted flight pitch, turn on the INVERT function (switch F set to

forward position) and activate the pitch curve inverted (PI-CRV, INVR) menu within

the Advance Menu to program the pitch. Whenever INVERT is activated, the

elevator, flap, and pitch servos respond in the opposite direction to how they respond

for forward flight. In addition, elevator and rudder trim is also reversed. The

hovering pitch function is active only at the forward flight side.

You can set the inverted cross position at the "INVERT, CRSS" screen within the

Advance Menu (see p. 77).

The TH-CUT function is used to kill the engine at the end of a flight. The engine

can be stopped with one touch with switch F (the momentary trainer switch is the

initial setting, but you may select another). This function eliminates the need to

move the trim to kill the engine and then move back to the idling position after each

flight. When the throttle stick is lower than the function ON/OFF set point throttle

position (normally a little above idle), the TH-CUT function responds to the operation

of the switch, and the throttle servo moves to its defined position.

The TH-CUT function will protect you from accidentally shutting off the engine.

When the throttle stick is above the set point, the TH-CUT function is not activated

even if the throttle cut switch is operated. In addition, you must move the throttle

stick back below the set point before the TH-CUT function can be reset, to avoid

sudden engine acceleration.

TH-CUT setup

Hook up and adjust the throttle linkage so that full throttle fully opens the

carburetor, and use the digital trim to make the engine idle at low throttle. Turn on

the throttle cut switch (switch F) and select the amount of offset to be just large

enough in the "–" direction (low throttle) to fully close the carburetor.

If you prefer, you may select another switch and ON-OFF direction. For safety,

always activate the TH-CUT function and use it.

You can use Throttle Curve menus to program a five-point curve so that the

engine speed responds the way you like relative to movement of the throttle stick.

You can set each of the five points over a 0% to 100% range.

There are three throttle curves: normal (NORM), idle-up 1 (IDL1), and idle-up 2

(IDL2). Only the basic normal throttle curve is displayed in the Basic Menu, but all

the curves may be programmed in the Advance Menu. For your convenience, the

normal curve can be programmed in either the Basic or Advance Menu, and it is

automatically updated in both places. Switch G is programmed so that you may

change between the normal (NORM), idle-up 1 (IDL1), and idle-up 2 (IDL2) curves.

The normal throttle curve (TH-CRV NORM) function is used to produce the basic

throttle curve for flight near hover. It is used along with the normal pitch curve (PI-

CRV NORM) so that the helicopter flies with constant rotor RPM. The normal

throttle curve function is ON at startup.

The idle-up curves should be programmed so that the engine maintains constant RPM

even when the pitch is reduced during flight. The curves should be matched to loops,

rolls, and other maneuvers, and are divided into idle-up curve 1 and idle-up curve 2.

The TH-CURV functions for IDL1 and IDL2 curves will not operate until the OFST-1

and OFST-2 functions are activated.

The Throttle Hold function holds the engine throttle in the idling position and

disengages it from the throttle stick, whenever switch E is activated. It is commonly

used during autorotation. You can set the throttle position to be held over a -50 to

+50% range centered about the throttle idle position. The throttle hold function also

includes a rudder offset option.

Rudder offset at throttle hold

The rudder offset function contained in throttle hold is used to offset the tail rotor

pitch neutral position during autorotation. It is set to keep the fuselage from rotating

only when the throttle hold function is active.

You may also input a time delay for the offset to be implemented (to prevent

sudden trim changes) in the DELAY menu within Advance menu (page 72).

The Offset 1, Offset 2,and Offset iv functions are used to offset (change the neutral

position) of the aileron, elevator, and rudder when switch G is used to switch to idle-up 1 (or

2) or switch F is used to switch to inverted flight. This function may be used to automatically

change the trim of a helicopter flying at high speed. A clockwise-rotation rotor helicopter

tends to drift to the right at high speed, so an aileron offset may be applied to offset the

helicopter to the left. You can use the DELAY function to make a smooth transition

between the differing neutral settings.

The necessary elevator offset varies with model geometry, so it must be determined by

noting pitch changes at high speed. The rudder offset is affected by both revolution mixing

(page 72), and trim (overall level movement) with the offset function. When the offset

function is ON, also the electronic trim levers will operate, so the trim amount in these flight

modes is automatically input to each offset amount.

The activating switches are initially set so that offset 1 and offset 2 are on at the same

time as the idle-up 1 and idle-up 2 functions, switched by Switch G. If desired, the offset

function ON/OFF operation can be changed to switch C. This may only be done in the

OFST-1 menu, and not in the OFST-2 menu.

In the helicopter mode, your T8UA system contains two separate programmable mixers

with unique mixing capabilities. You may use mixing to correct any tendencies of the

helicopter during aerobatics that you want to eliminate, making operation more pleasant.

Besides mixing between arbitrary channels, the mixers may be linked with the Advance

menus in the T8UA, or the mixing curve can be offset relative to the master’s neutral. You

may select which switch activates your mixers from the eight switches A-G or throttle, and

you may choose whether the trim from the master also affects the slave channel.. The Link

function is used to ‘link’ programmable mixers with other mixing menus.

The default channels for Mixers 1 & 2 are set to frequently-used mixing combinations as

follows: PMIX-1 = AIL→ELE, PMIX-2 = ELE→THR. The programming method is given

for Mixer #1; the second mixer may be programmed in an identical fashion.

The Hovering Throttle function may be used to trim the throttle near hover without

affecting pitch. Its position can be memorized so that when the model memory is recalled,

the original trim is repeated by rotating the knob to its center position.

When the hovering throttle knob is turned clockwise, the engine speed rises and when

turned counterclockwise, the engine speed drops. Changes in rotor speed caused by

temperature, humidity, or other conditions can be accommodated. When used with the

hovering pitch function, more exact trimming is possible.

Revolution mixing is used to mix pitch→rudder to suppress the torque reaction

generated by changes in the pitch and speed of the main rotor. The mixing ratio can

be set by a five-point curve.

Three are three kinds of revolution mixing: normal (NORM), idle-up 1 (IDL1),

and idle-up 2 (IDL2). Only basic NORM revolution mixing is displayed in the Basic

Menu, but all the revolution curves are visible in the Advance Menu. If you program

the normal curve in the Basic Menu, the same curve is automatically reflected in the

REVOLU NORM menu within the Advance Menu, and vice versa.

The REVOLU functions for the IDL1 and IDL2 curves will not operate until the

OFST-1 and OFST-2 functions are activated.

These two functions set the mixing rate so that the fuselage direction is straight

ahead during high-speed flight. You can set either a curve or offset position to

match the helicopter’s tendencies. You may also program in reverse rudder mixing

for 3D flight.

The pitch curve is defined by a 5-point curve so that you may set the best pitch motion

relative to throttle stick movement. Each point on the curve can be adjusted over a 0% to

100% range.

The T8U system contains five pitch curves: normal (NORM), idle-up 1 (IDL1), idle-up 2

(IDL2), hold (HOLD), and inverted (INVR). The basic normal pitch curve is the only one

displayed in the Basic Menu, but all of the pitch curves can be viewed in the Advance menu.

The Normal curve is exactly the same in both the Advance and Basic Menus.

Use the idle-up switch (switch G) to move between Normal, idle-up 1, and idle-up 2.

(The PI-CURV functions for IDL1 and IDL2 curves will not operate until the OFST-1 and

OFST-2 functions are activated.) Switching to the hold (HOLD) function is performed with

switch E. Switching to the inverted (INVR) function is performed with switch H. Note

that whenever the hold switch is turned on, it has priority regardless of the idle-up switch

osition. p

The normal (NORM) pitch curve function produces the basic pitch curve for flight near

hover. It is set up to provide up and down control at a constant engine speed along with the

ormal throttle curve. n

The HI-side pitch curve limits the maximum rotor pitch so that a large load is not applied

to the engine. The LO-side pitch curve produces a curve with a minimum pitch of -4°.

Idle-up 1 is used for 540° stall turns, looping, and rolling stall turns, while idle-up 2 is used

or rolls. f

The throttle hold curve is used when performing autorotations, and should provide pitch

from -4° to +12°. To get this pitch range, set the HI and LO rates to +100% and -100%

respectively.

Input 5-point curve values

Move the lower arrow to the

position you want to set with the

CURSOR keys (the curve point is

indicated by the arrow below the

numbers 1-5, and the current

throttle position is above the

numbers). Enter the desired curve

value with the (+)/(-) keys.

• If you're unhappy with what you've

set, you may return to the default

value by pressing the (+) and (-)

keys simultaneously.

Curve Point Value

Initial curve settings:

POS1 = 0%

POS2 = 25%

POS3 = 50%

POS4 = 75%

POS5 = 100%

The Pitch Curve Normal function is on at startup.

The blinking item on the

setting screen is the

current setting item.

Idle-up 1 Pitch Curve Setting

The PI-CRV IDL1 function will not operate until the OFST1

function is activated. This also activates the IDL1 Throttle &

REVOLU curve menus. You can activate idle-up 1 and idle-up 2

independently.

The curve setting procedure is the same as normal curve

described above.

Throttle Hold Pitch Curve Setting

The PI-CRV HOLD function will take data, but will not operate

until the throttle hold (TH-HLD) function is activated.

The curve setting procedure is the same as normal curve

described above.

To PI-CRV IDL2 function

To PI-CRV INVR function

Invert Pitch Curve Setting

The PI-CRV INVR function will take data, but will not operate until

the INVERT function is activated.

The curve setting procedure is the same as normal curve

described above.

The setting data for 8 models can be saved in the T8UAPS transmitter itself and

the setting data for 8 more models can be saved in the DP-16K CAMPac (Option)

removable memory module.

CAMPac initialization

To use the CAMPac with the T8UAPS, the CAMPac must be initialized when the

power is turned on for the first time. After the message "INIT? EXT-MEM" appears

on the screen when the power is turned on, press the "+" key. This automatically

initializes the storage area for 8 models. Further operation is unnecessary.

DP-16K CAMPac (Option)

When using the DP-16K CAMPac, remove the transmitter dust cap

and insert the data pack as far as it will go.

Always turn off the transmitter power before inserting or removing

the data pack.

The data memorized in the data pack using an old 8U Series can be copied to the memory in

the body of the 8Usuper Series transmitter. When old data is copied, initialization data for the

new functions added with the 8Usuper are added.

(1) Call the copy function in the BASIC menu/MODEL submenu. (Call the "Pac" screen

following "COPY" of the function name display at the top left of the screen.)

(2) Select the model No. you want to copy using the + or - key.

(3) Press the + and - keys simultaneously two times. (The data is copied to transmitter side

model No. 8.)

However, when data saved for mixing type "H-2" for helicopters using an old model was

copied to the T8UAPS transmitter, whereas the aileron and pitch travel in the old setting data

is fixed at 60%, both the aileron and pitch initial value settings of the new function (swash

AFR function) of the T8UAPS is 50%. Therefore, the travel is reduced by that amount.

Readjust after copying the setting data.

All the data memorized in the CAMPac using an old 8U Series can be batch converted to

8USUPER Series transmitter data. However, the converted CAMPac cannot be used with an

old 8U Series transmitter.

(1) While pressing the two BASIC menu keys simultaneously, turn on the transmitter power

switch. (The conversion function screen is called.)

(2) Press the + key. (Conversion is started and all the models data in the data pack are

converted.)

The data memorized in the data pack using the 8USUPER Series cannot be used with the old

8U Series.

The setting data (transmitter body and CAMPac) are memorized in memory elements that do

not require a back-up battery. Therefore, the data can be used while ignoring the back-up

battery life. Of course, the setting data is not destroyed even when the transmitter battery is

replaced.

The abbreviations used with the 8UA are defined below alphabetically. Related pages are

given in parenthesis following the definition ().
