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.

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.
