Meaning of Special Markings
Pay special attention to safety where indicated by the following marks:
DANGER - Procedures which may lead to dangerous conditions and cause death/serious injury if not carried out properly.
WARNING - Procedures which may lead to a dangerous condition or cause death or serious injury to the user if not
carried out properly, or procedures where the probability of superficial injury or physical damage is high.
CAUTION - Procedures where the possibility of serious injury to the user is small, but there is a danger of injury, or
physical damage, if not carried out properly.
= Prohibited = Mandatory
Warning: Always keep electrical components away from small children.
FLYING SAFETY
To ensure the safety of yourself and others, please observe the following precautions:
Have regular maintenance performed. Although your 9C protects the model memories with non-volatile EEPROM
memory (which does not require periodic replacement) and not a battery, it still should have regular checkups for wear
and tear. We recommend sending your system to the Futaba Service Center annually during your non-flying-season
for a complete checkup and service.
Ni-Cd Battery
Charge the batteries! (See Charging the Ni-Cd batteries, p. 14, for details.) Always recharge the transmitter and
receiver batteries for at least 8 hours before each flying session. A low battery will soon die, causing loss of control
and a crash. When you begin your flying session, reset your 9C’s built-in timer, and during the session pay attention
to the duration of usage.
Stop flying long before your batteries become low on charge. Do not
rely on your radio’s low battery warning
systems, intended only as a precaution, to tell you when to recharge. Always check your transmitter and
receiver batteries prior to each flight.
Where to Fly
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 in the US by contacting the Academy of Model Aeronautics.
You can also contact the national Academy of Model Aeronautics (AMA), which has more than 2,500 chartered clubs across the
country. Through any one of them, instructor training programs and insured newcomer training are available. Contact the AMA
at the address or toll-free phone number below.
Academy of Model Aeronautics
5151 East Memorial Drive
Muncie, IN 47302-9252
Tele. (800) 435-9262
Fax (765) 741-0057
or via the Internet at http:\\www.modelaircraft.org
5
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 three-to-five-mile range, or you may
lose control of your aircraft or cause someone else to lose control.
At 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. It is never 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 at any one time.
To prevent possible damage to your radio gear, turn the power switches on and off in the proper sequence:
1. Pull throttle stick to idle position, or otherwise disarm your motor/engine.
2. Turn on the transmitter power and allow your transmitter to reach its home screen.
3. Confirm the proper model memory has been selected.
4. Fully extend the transmitter antenna.
5. Turn on your receiver power.
6. Test all controls. If a servo operates abnormally, don’t attempt to fly until you determine the cause of the problem.
(For PCM systems only: Test to ensure that the FailSafe settings are correct by waiting at least 2 minutes after
adjusting then, turning the transmitter off and confirming the proper surface/throttle movements. Turn the transmitter
back on.)
7. Start your engine.
8. Complete a full range check (see p. 17).
9. After flying, bring your throttle stick to idle position, engage any kill switches or otherwise disarm your motor/engine.
10. Turn off receiver power.
11. Turn off transmitter power.
If you do not turn on your system in this order, you may damage your servos or control surfaces, flood your engine, or in the
case of electric-powered or gasoline-powered models, the engine may unexpectedly turn on and cause a severe injury.
While you are 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 speed up. Also,
damage to your transmitter may occur.
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. Never fly if lightning is expected.

as seen on the screen of the 9C, that name, feature, or abbreviation will be exactly as seen on the radio’s screen, including
capitalization and shown in a DIFFERENT TYPE STYLE for clarity. Any time we mention a specific control on the radio itself,
such as moving SWITCH A, KNOB VR(B), or the THROTTLE STICK, those words will be displayed as they are here.

MODULE: 72TP-FM
•
Module may be easily removed and a module on a different channel (or even band) reinserted to change the frequency
on which the 9C transmits.
•
Module transmits both FM (PPM) and PCM. No need for a second module.
•
All transmission circuitry is included in the module, so no retuning is needed when changing channels or even bands.
•
Frequency band is changed by inserting a module on the proper band, including for international or ground model use.
•
In North America it is against FCC regulation to change the crystal within the transmitter module to a different
channel. All such transmitter crystal changes must be performed by a certified radio technician. Failure to properly tune
a system to its new channel may result in decreased range and may also result in interference to other types of frequency
users on adjoining channels. Doing so also voids your AMA insurance.
•
The FSS synthesized module for the 9Z family of radios is NOT compatible with the 9C.
•
Radio system beeps and RF LIGHT goes out to indicate module is not installed and radio is not transmitting.
•
Non-Futaba brand modules are not FCC certified for use with this radio and therefore are against FCC regulation to use.
Doing so also voids your AMA insurance.
•
TJ75FM modules may also be used with the 9C for ground use models such as robotics, rocketry, trains, cars, and boats.
RECEIVER: R138/R148/R149
•
The R138 or R148 FM 8-channel or the R149 PCM 9-channel receiver included with your system is a high-sensitivity
narrow-band dual-conversion receiver.
•
Note that your 9C transmitter is capable of transmission on both PPM (FM) and PCM with just a simple programming
change and just turning the transmitter off and back on. (See p. 28.)
•
Any Futaba narrow band FM receiver (all produced after 1991) on the correct frequency band and frequency may be
used with the 9C.
•
Any Futaba PCM 1024 receiver on the right frequency band and frequency may be used with the 9C (all 1024 receivers
say PCM1024; receivers which say PCM but not 1024 are 512 resolution and not compatible).
NEVER attempt to change a receiver’s band
by simply changing crystal (IE removing a 72MHz crystal and inserting
a 75MHz crystal). A receiver that has a crystal installed from a different frequency band without retuning will not
receive properly and will have dramatically decreased range.
•
In North America the receiver included with this system may have its frequency changed by simply changing the crystal
as long as it remains in the same half the band. A low band receiver between channels 11 and 35 may be changed to
any other channel between 11 and 35 without requiring any tuning. A high band receiver between channels 36 and 60
may similarly be changed. Receivers being changed from a high band channel to a low band or vice versa require proper
tuning and service by the Futaba Service Center.
SERVOS
• Please see technical specifications page for specifics on the servos included with your system.
• The included receiver is compatible with all J-plug Futaba servos, including retract, winch, and digital servos.

CAMPac Memory module - the optional DP-16K CAMPac increases your model storage capability (to 14 models from
8) and allows you to transfer programs to another 9C transmitter. Note that data cannot be transferred to/from any other
model of transmitter (i.e. 8U, 9Z, etc).
Insertion of a CAMPac containing data of a different transmitter type (ex: 9Z) will result in a complete
CAMPac data reset and loss of all data.
•
NT8S Transmitter battery pack - the (600mAh) transmitter Ni-Cd battery pack may be easily exchanged with a fresh
one to provide enough capacity for extended flying sessions.
•
Trainer cord - the optional training cord may be used to help a beginning pilot learn to fly easily by placing the instructor on
a separate transmitter. Note that the 9C transmitter may be connected to another 9C system, as well as to many other models
of Futaba transmitters. The 9C transmitter uses the newer rectangular type cord plug. Both new-to-new and new-to-round plug
style trainer cords are available.
•
FTA8 Neckstrap - a neckstrap may be connected to your T9C system to make it easier to handle and improve your flying
precision, since your hands won’t need to support the transmitter’s weight.
•
Y-harnesses, servo extensions, etc - Genuine Futaba extensions and Y-harnesses, including a heavy-duty version with heavier
wire, are available to aid in your larger model and other installations.
•
5-cell (6.0V) receiver battery packs - All Futaba airborne equipment (except that which is specifically labeled otherwise) is
designed to work with 4.8V (Ni-Cd 4 cells) or 6.0V (Ni-Cd 5 cells or alkaline 4 cells). Using a 6.0V pack increases the current
flow to the servos, which accelerates their rate of response and their torque. However, because of this faster current draw, a 5-
cell battery pack of the same mAh rating will last approximately ¾ the time of a 4-cell pack.
•
R309DPS - Synthesized receiver which can be changed to any 72MHz frequency with the turn of 2 dials, no tuning needed.
•
Gyros - a variety of genuine Futaba gyros are available for your aircraft or helicopter needs. See p. 64 for aircraft or
p. 89 for helicopter gyro information.
•
Governor (GV1) - for helicopter use. Automatically adjusts throttle servo position to maintain a constant head speed
regardless of blade pitch, load, weather, etc. See p. 89 for details.
•
DSC Cord - allows setup and testing without transmitting. Requires DSC compatible receiver (R149DP or R309DPS)
and DSC cord. With Transmitter and Receiver off, plug cord into trainer port then, into receiver battery slot. All
programing and setup may be done in this manner without transmitting.
•
TP72FM modules - additional modules on other frequencies within the 50MHz (licensed operators only) and 72 MHz
bands may be purchased to utilize your transmitter with receivers on other frequencies. Additionally, the TK and
TJ75MHz modules may be used with the 9C. (See p.8)
•
Receivers - various models of receivers may be purchased for use in other models. (See p. 8.)

RADIO INSTALLATION
While you are installing the battery, receiver, switch harness and servos into your model’s fuselage, please pay attention to
the following guidelines:
Use the supplied rubber grommets when you mount each servo. Be sure not to
over-tighten the screws. If any portion of the servo case directly contacts the fuselage or
the servo rails, the rubber grommets will not dampen the vibration, which can cause
mechanical wear and servo failure.
Servo Throw
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.
Switch Harness Installation
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 where it can’t be inadvertently turned on or off during
handling or storage. Install the switch so it moves without restriction and snaps from ON to OFF and vice versa.
Receiver Antenna
It is normal for the receiver antenna to be longer than the fuselage.
DO NOT cut 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 or
carbon fiber pushrods or cables. Be sure to perform a range check before flying.
Receiver Notes
When you insert servo, switch 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 away to plug into the receiver, use an aileron extension cord to extend the length
of the servo lead. Additional Futaba extension cords of varying lengths are available from your hobby dealer. Always use an
extension of the proper length. Avoid plugging multiple extensions together to attain your desired length. If distance is greater than
18” or multiple or high current draw servos are being used, use Futaba Heavy-Duty servo extensions.
Receiver Vibration and Waterproofing
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 is 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 rubber. If you accidentally get moisture or fuel inside the receiver, you may experience intermittent
operation or a crash. If in doubt, send the receiver for service.

WARNING & ERROR DISPLAYS
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.
MODEL SELECTION ERROR: Warning sound: 5 beeps (repeated 3 times)
The MODEL SELECTION warning is displayed when the transmitter attempts to load a model memory from a memory module
(optional CAMPac) 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.
LOW BATTERY ERROR: Warning sound: Continuous beep until transmitter is powered off.
The LOW BATTERY warning is displayed when the transmitter battery voltage drops below 8.5V.
THIS IS NOT AN “OK TO FLY” to this level! This is a warning that the radio is about to shut off.
Land your model as soon as possible before loss of control due to a dead battery.
MIXER ALERT WARNING: Warning sound: 5 Beeps (repeated until problem resolved or overridden)
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, Start and Speed mixing HELI:Throttle cut, throttle hold, idle-up
If turning a 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 previously 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 both SELECT
BUTTONS
simultaneously. Then change one of the switch
settings of the mixings duplicated at one switch.
BACKUP ERROR: Warning sound: 4 beeps (repeated continuously)
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.
MEMORY MODULE INITIALIZE DISPLAY
This warning appears when an (optional) CAMPac memory module is used in the transmitter for the first time. When the
M
ODE BUTTON
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.
The 9C CANNOT convert data from other radio types (ie. 8U, 9Z). Installation of a CAMPac with data from
another radio type will result in reinitialization of the CAMPac and loss of all data.
RF MODULE WARNING: Warning sound: A single long beep. The single beep lets you know that the RF module has been
removed from the transmitter, or is not being read properly. The green RF light also goes out.

AIRCRAFT (ACRO) MENU FUNCTIONS
Please note that all BASIC menu functions are the same for airplanes (ACRO), sailplanes (GLID1FLP/2FLP), and helicopters
(HELISWH1/SWH2/SWH4/SR-3/SN-3). The glider BASIC menu does not include IDLE-DOWN or THR-CUT; the helicopter
BASIC menu includes additional features (swashplate adjustment and throttle/pitch curves and revo for Normal flight mode)
that are discussed in the Helicopter section.

A QUICK GUIDE: GETTING STARTED WITH A BASIC 4-CHANNEL AIRCRAFT
This guide is intended to help you get acquainted with the radio, to give you a jump start on using your new radio, and to give you
some ideas and direction in how to do even more than you may have already considered. It follows our basic format of all
programming pages: a big picture overview of what we accomplish; a “by name” description of what we're doing to help acquaint
you with the radio; then a step-by-step instruction to leave out the mystery when setting up your model.
For additional details on each function, see that function's section in this manual. The page numbers are indicated in the
goals column as a convenience to you.
See p.21 for a legend of symbols used.

Set up IDLE-DOWN.
P. 33.
IDLE-DOWN slows the engine's idle for
landings, sitting on the runway, and
maneuvers such as spins. The normal
(higher idle) setting (when IDLE-DOWN
is off) is for engine starting, taxi, and
most flight maneuvers, to minimize
chance of a flame-out.

MODEL COPY: copies the current model data into another model memory (in the transmitter or the optional DP-16K
CAMPac). The name of the model memory you are copying into is displayed for clarity.
Notes:
•
Any data in the model copied to will be written over and lost, including name, type and
modulation. It cannot be recovered.
•
To copy from one 9C to another, use an optional CAMPac. (Note: The model may be
flown directly off the CAMPac's memory, not requiring re-copying into the 2nd
transmitter. For more information on CAMPacs, please see p. 10.)
•
With the trainer FUNC mode it is not necessary to have the student radio contain the
setup of the aircraft. See TRAINER, p. 40.
Data cannot be converted from 8U or 9Z memory types. If a CAMPac is installed into the 9C that has data on it from
another radio type, it will have to be re-initialized which deletes all data.
Examples:
•
Start a new model that is similar to one you have already programmed.
•
Copy the current model data into another model memory as a backup or before experimenting with new settings.
•
Store your model data to an optional CAMPac prior to sending your radio for service.
•
Edit a copy of your model’s data to fly the model in different conditions (ie. Helicopter using heavier night blades; glider
in extreme wind; airplane model at extreme altitudes).
•
Store your model data to an optional CAMPac to use or copy the settings into a friend's 9C (A or H) transmitter so he
can fly your model or use it as a starting point for setting up a similar model.
GOAL of EXAMPLE: STEPS: INPUTS:
*Radio emits a repeating "beep" and shows progress on screen as the model memory is being copied. Note that if the power switch is turned off prior
to completion, the data will not be copied.

MODEL TYPE: sets the type of programming used for this model.
The 9C has 8 model memories, which can each support:
•
one powered aircraft (ACRO) memory type (with multiple wing and tail configurations. See twin aileron servos, twin
elevator servos, ELEVON, and V-TAIL for further information.);
•
two glider wing types (again with multiple tail configurations). See Glider MODEL TYPE for details, p. 68;
•
five helicopter swashplate types, including CCPM. See Helicopter MODEL TYPE for details, p. 77.
Before doing anything else to set up your aircraft, first you must decide which MODEL TYPE best fits this particular aircraft.
(Each model memory may be set to a different model type.) If your transmitter is a 9CA, the default is ACRO. If it is a 9CH,
the default is HELI(SW1).
ACRO is the best choice for most powered airplanes, but in some circumstances, GLID2FLP may be a better choice. ACRO
is usually a better choice because of functions it offers that the GLID types do not:
•
ACRO adds:
•
SNAP-ROLL
•
AILEVATOR (twin elevator servo support)
•
AIRBRAKE (a more assignable version of BUTTERFLY)
•
For fuel-powered airplanes: IDLE-DOWN, THR-CUT, THROTTLE-NEEDLE mixing and THROTTLE DELAY programming.
•
But ACRO lacks:
•
START and SPEED OFFSETS
•

to return to BASIC menu.
Modulation select (MODUL): sets the type of modulation transmitted.
The modulation of your receiver will determine whether you utilize PPM or PCM setting in MODUL during transmission.
Note that you have to turn your transmitter off and back on before a modulation change becomes effective. If you choose
PCM, be sure you understand and set the FailSafe (F/S) settings as you intended (see p. 43). Both modulations transmit on
FM waves, use the FM trainer cord, and the FM module.
PCM = Pulse Code Modulation PPM = Pulse Position Modulation (also called FM).
Adjustability:
•
PCM setting for all Futaba PCM1024 receivers, regardless of number of channels (ie.
R138DP/148DP/149DP, R309DPS);
•
PPM setting for all Futaba compatible (negative shift) FM receivers, regardless of
number of channels (ie. R127DF, R123F, R148DF).
•
Not compatible with PCM512 receivers such as the R128DP and R105iP.
•
Not compatible with other brands of PCM receiver, or positive shift FM receivers
(ie. JR, Airtronics).
•
You do not need a different module in the radio to transmit in PCM. For more
information on PCM, please see our website.
GOAL of EXAMPLE: STEPS: INPUTS:
Second aileron (AIL-2) (ACRO/ GLID1FLP only): changes the default choice for dual aileron servos from channels 6
(FLAPERON) or 7 (AIL-DIF) to channels 5 and 6. This allows you to utilize these 2 great functions while utilizing a 5-channel
receiver. NOTE: Changing AIL-2 only
tells the system which servos to utilize if FLAPERON or AIL-DIF is activated. You still
must activate that function and complete its setup. For details on twin aileron servos, including using AIL-2, see p. 47.
NOTE: When you change models in MODEL SELECT, if the
new model is set to the other modulation type, you must
cycle the transmitter power to change modulations. The
modulation will flash on the home screen to remind you
until you do so. See p. 25, MODEL SELECT, for details.

POWER OFF. POWER ON.
Now that the model is in the proper modulation, the 9C should communicate
with the receiver. If it does not, confirm the modulation/frequency of the
receiver. [Futaba receivers ending in F use PPM (ex: R127DF), ending in P use
PCM (ex: R149DP)].
Change MODEL TYPE to glider/helicopter: see p. 28.
Set F/S settings for when PCM receiver sees interference: see p. 43.
Utilize servo REVERSE: see p. 31.
Adjust servo travel with END POINT: see p. 32.
Set up dual/triple rates and exponential (D/R,EXP): see p. 35.
Adjustable travel limit (ATL): makes the channel 3 TRIM LEVER (THROTTLE TRIM) effective only at low throttle, disabling the trim
at high throttle. This prevents pushrod jamming due to idling trim changes. This function defaults to ON. If you are not using
channel 3 for throttle, you may want trim operation the same as on all other channels. To do so, set ATL to OFF.
If you need the ATL to be effective at the top of the stick instead of the bottom, reverse the THR-REV setting. Note that this
affects all models in the radio, not just the model you are currently editing. See servo REVERSE, p. 31.
GOAL of EXAMPLE: STEPS: INPUTS:
Servo reversing (REVERSE): changes the direction an individual servo responds to a CONTROL STICK motion. [Since channel 9 is
switch only (and only available with a PCM receiver), its servo REVERSE is in the AUX-CH control screen with its switch assignment.
See p. 39.] For CCPM helicopters, be sure to read the section on SWASH AFR (p. 79) before reversing any servos.
Except with CCPM helicopters, always complete your servo reversing prior to any
other programming. If you use pre-built ACRO/GLID functions that control multiple
servos, such as FLAPERON or V-TAIL, it may be confusing to tell whether the servo needs
to be reversed or a setting in the function needs to be reversed. See the instructions for
each specialized function for further details.
Always check servo direction prior to ever
y flight as an additional precaution to confirm proper model memory,

NOTE: THR-REV is a special function that reverses the entire throttle control, including moving the trim functionality to the
Stick’s upper half. To use THR-REV, turn off the transmitter, hold down the MODE and END keys, turn on. CURSOR DOWN to
THR-REV and turn the DIAL to REV. Turn the transmitter off and back on. This change affects all models in the radio.

End Point of servo travel adjustment (END POINT, also called EPA): the most flexible version of travel adjustment
available. It independently adjusts each end of each individual servo’s travel, rather than one setting for the servo that
affects both directions. Again, for CCPM helicopters, be sure to see SWASH AFR (see p. 79) prior to adjusting end points.
Adjustability:
•
Can set each direction independently.
•
Ranges from 0% (no servo movement at all) to 140%. 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.
Examples:
•
Adjust the throttle high end to avoid binding at the carburetor, and low end to allow for proper carburetor closure.
•
Adjust flap so up travel is only sufficient for straight and level flight trimming, with full down travel.
•
END POINT may be adjusted to 0 to keep a servo from moving one direction, such as flaps not intended to also operate
as spoilers.
•
Retract servos are not proportional. Changing END POINT will not adjust the servo.
END POINT adjusts only the individual servo. It will have no effect on any other servo that is operated in conjunction with
this servo via mix or preset programming such as FLAPERON, AILEVATOR, etc. This is so that each individual servo can be
carefully fine-tuned to avoid binding and other conflicts. To adjust the total travel of a function such as FLAPERON, make
the adjustments in that function's controls. For CCPM helicopters, adjust the total travel of the function, such as collective
pitch, in SWASH AFR.
Adjust the linkage or the END POINT? It is nearly always best to adjust your linkages to get as close as possible prior to
utilizing END POINT. The higher the END POINT setting, the better position accuracy and the more servo power available at
nearly any position (except if using digital servos). Higher END POINT values also mean longer travel time to reach the
desired position, as you are utilizing more of the servo's total travel. (For example, using 50% END POINT would give you
only half the steps of servo travel, meaning every click of trim has twice the effect and the servo gets there in half the time).
•
end point (and moving the linkage) = torque, accuracy, but transit time to get there.
•
end point (instead of adjusting linkages) = travel time, but torque, accuracy.

Engine idle management: IDLE-DOWN and THR-CUT: functions which work with the digital THROTTLE TRIM to provide a
simple, consistent means of engine operation. No more fussing with getting trim in just the right spot for landings or take
offs! For additional engine adjustments, see THROTTLE-NEEDLE (p. 56) and THROTTLE DELAY (p. 57).
If your throttle cut and idle down are working at the wrong end of your travel — full throttle not idle — then your
THR REV feature has been reversed. Please see page 31 for instructions.
IDLE-DOWN (ACRO only): lowers the engine idle for: sitting on the runway prior to take off, stalls and spins, and landings.
The normal idle setting is a little higher for easier starts and safe flights with less risk of dead sticks.
Important note: The IDLE-DOWN function is not normally used when starting the
engine, and its accidental operation may keep your engine from starting. The 9C
warns that IDLE-DOWN is on when the transmitter is turned on. Be sure to turn off the
function, or override the warning by pressing both 2 SELECT/CURSOR keys in unison
and holding for 1 second if you intended the function to be on.
This may be assigned to any switch/position. Some modelers accidentally assign IDLE-DOWN to one side of a switch
and THR-CUT to the other. There is no “normal” setting to start the engine. By default IDLE-DOWN is set to SWITCH
C center and down. This works well with THR-CUT also on SWITCH C down. The SWITCH up is normal flight/starting,
center for slower maneuvers/landing, and down to cut the engine. If you assign IDLE-DOWN or THR-CUT to the spring-
loaded TRAINER SWITCH F (9CA) or H (9CH), then use the trainer function, you may risk loss of throttle control or
deadstick for your student.
GOAL of EXAMPLE: STEPS: INPUTS:
*Normally a value of 10- 20%. Secure the fuselage, engine running. Set the T

Throttle cut (THR-CUT) (ACRO/HELI): provides an easy way to stop the engine by flipping a switch (with THROTTLE STICK
at idle). The movement is largest at idle and disappears at high throttle to avoid accidental dead sticks. In HELI, there is an
additional setting, THR. See p. 82.
The switch's location and direction must be chosen. It defaults to OFF to avoid
accidentally assigning it to a switch, which might result in an unintentional dead stick in
flight. Please see for IDLE-DOWN and THR-CUT on p. 33.
GOAL of EXAMPLE: STEPS: INPUTS:
*Normally, a setting of 10-20% is sufficient. Viewing the carburetor barrel until it fully closes is adequate to get an approximate setting; then test with

Dual/triple rates and exponential (D/R,EXP): assigns adjusted rates and exponential.
Dual/Triple Rates: reduce/increase the servo travel by flipping a switch, or
(ACRO/GLIDER) they can be engaged by any stick position. Dual rates affect the control
listed, such as aileron, not just a single (ex: channel 1) servo. For example, adjusting
aileron dual rate will affect both aileron servos when using FLAPERON or AIL-DIF, and both
aileron and elevator servos’ travel when using AILEVATOR or ELEVON or a CCPM helicopter.
Activation:
•
Any SWITCH, A-H. If you choose a 3-position switch, then that dual rate instantly becomes a triple rate (see example).
•
Stick position (ACRO/GLIDER). (Ex: On rudder you normally use only the center 3/4 of the stick movement except
for extreme maneuvers such as snaps/spins/stalls. As long as your RUDDER STICK does not exceed 90% of maximum
throw, the rudder responds at your lower rate, allowing small, gentle corrections. When the stick passes 90% (ie. stall
turn), the rudder goes to high rate’s 90%, which is a MUCH higher amount of travel than your low rate at 89%.)
Ex: EPA = 1” Low Rate = 50% High Rate = 100%
At 89% Low Rate = .45”
At 90% High Rate = .9”
Adjustability:
•
Range: 0 - 140% (0 setting would deactivate the control completely.)
Initial value=100%
•
Adjustable for each direction(ACRO/GLIDER). (ie. Up/down,
left/right) (Ex: Most models fly upright without any elevator trim,
but require some down elevator when inverted just to maintain
level flight. By increasing the down travel by the amount required
to hold the model inverted, the model now has equal travel
available from level upright or level inverted.)
Exponential: changes the response curve of the servos relative to the stick position to make flying more pleasant. You
can make the servo movement less or more sensitive around neutral for rudder, aileron, elevator, and throttle (except HELI
type - use THROTTLE CURVE instead).
Why use expo? Many models require a large amount of travel to perform their best tricks. However, without exponential,
they are “touchy” around neutral, making them unpleasant to fly and making small corrections very difficult. Additionally,
by setting different exponentials for each rate, you can make the effectiveness of small corrections similar in each rate, as
in our example below.
The best way to understand exponential is to try it:
•
Having made no changes yet in the D/R,EXP screen, move S
WITCH D to “down” (toward the AILERON STICK
).
•
Cursor down to EXP and dial to 100%.
•
Move S
WITCH D up. Hold the AILERON STICK
at ¼ stick and move S
WITCH D down.
•
Notice how much less travel there is.
•
Go to 3/4 stick and repeat. Notice how the travel is much closer, if not identical.

Adjustability:
•
More sensitive around neutral. (positive exponential, see example)
•
Less sensitive around neutral. (negative exponential, see example)
•
Adjustable for each direction. (ACRO/GLIDER)
For throttle, exponential is applied at the low end to help nitro and gasoline engines have a linear throttle response, so that
each 1/4 stick increases engine RPM 25% of the available range. (In most engines this ranges from 5-60%.)
Special note for helicopters: Helicopter model types have just a single rate for each switch position rather than a rate for
each side of the servo’s travel per switch position. Additionally, setting the D/R,EXP for each switch position requires
cursoring back to the No. setting and changing the switch position here. Just flipping the switch does not affect the screen
setting, allowing dual rates to be assigned with idle-up and other features on certain switches, and does not require putting
the model in that condition to make modifications.

GOAL of EXAMPLE: STEPS: INPUTS:
37
Set up aileron triple rates on S
WITCH C
with travel settings of 75% (normal),
25% (slow roll) and 140% (extreme
aerobatics) and exponential settings of
0%, +15%, and -40% respectively.
NOTE: This normal rate has no
exponential so it has a very linear,
normal feel. This slow roll rate has
positive exponential (the opposite of
what most people normally use),
which makes the servos more
responsive around center. This makes
the servos feel the same around center
in the normal and low rates, but still
gives a very slow roll rate at full stick.
The 3D rate (extreme aerobatics) has a
very high distance of travel B nearly
twice that of the normal rate.
Therefore, using a very high negative
exponential setting softens how the
servos respond around center stick.
This makes the servos respond
similarly around center stick for a
more comfortable feel.
Many modelers like to set up all 3
triple rates on a single 3-position
switch, creating a “slow and pretty
mode”, a “normal mode”, and a “wild
stunts mode” all with the flip of a
single switch. To do so, simply set up
rates for all 3 controls and assign all 3
to the same 3-position switch.

Auxiliary channel function (including channel 9 controls) (AUX-CH): defines the relationship between the transmitter
controls and the receiver output for channels 5-9. Also, the CH9 SERVO REVERSE is used to change the CH9 servo direction.
Note that the CH9 functions are only visible in the AUX-CH screen when PCM modulation is selected. The 9th channel is
not supported in FM modulation.
Adjustability:
•
channels 5-9 may be assigned to any SWITCH (A-H), slider [VR(D) and VR(E)], or
knob [VR(A-C)] (for example, moving flaps to a switch or slider), but not the
primary control sticks (use programmable mixes to do so, p. 59);
•
multiple channels may be assigned to the same switch, slider or knob;
•
channels set to “NULL” are only controlled by mixes. (Ex: utilizing 2 channels for 2
rudder servos. See mixes, p. 59.)
Remember that if you assign primary control of a channel to a switch which you later use for other functions (like
dual/triple rates or airbrakes), every time you use that other function you will also be moving the auxiliary channel.

SUB-TRIM: makes small changes or corrections to the neutral position of each servo. Range is -120 to +120, with 0 setting,
the default, being no SUB-TRIM.
The recommended procedure is as follows:
•
measure and record the desired surface position;
•
zero out both the trims (TRIM RESET menu) and the SUB-TRIMs (this menu);
•
mount servo arms and linkages so that the control surface’s neutral is as correct as possible; and
•
use a small amount of SUB-TRIM to make fine corrections.
GOAL of EXAMPLE: STEPS: INPUTS:
SERVO display and cycle submenu: displays radio's output to channels 1-8.
The servo submenu includes two features:
•
real-time bar-graph display to demonstrate exactly what commands the transmitter is
sending to the servos. (This can be particularly handy in setting up models with
complicated mixing functions, because the results of each stick, lever, knob, switch
input and delay circuit may be immediately seen.); and
•
servo cycle function to help locate servo problems prior to in-flight failures.
GOAL of EXAMPLE: STEPS: INPUTS:
We recommend that you center the digital trims before making SUB-TRIM
changes, and that you try to keep all of the SUB-TRIM values as small as
possible. Otherwise, when the SUB-TRIMs are large values, the servo's
range of travel is restricted on one side.

FailSafe (loss of clean signal and low receiver battery) submenu (PCM mode only) (F/S): sets responses in case of loss
of signal or low Rx battery.
FailSafe (F/S): instructs a PCM receiver what to do in the event radio interference is received.
Adjustability:
•
Each channel may be set independently.
•
The NORM (normal) setting holds the servo in its last commanded position.
•
The F/S (FailSafe) function moves each servo to a predetermined position.
•
NOTE: the setting of the throttle's F/S also applies to the Battery F/S (see below).
Examples:
•
The F/S setting is used in certain competitions to spin the aircraft to the ground prior to flying away and doing potential damage
elsewhere. Conversely, may also be used to go to neutral on all servos, hopefully keeping the plane flying as long as possible.
•
Competition modelers often maintain the NORM function so that brief interference will not affect their model's maneuver.
•
Set the throttle channel so that the engine idles when there is interference (ACRO). This may give enough time to fly away
from and recover from the radio interference and minimize damage if crashed.
•
For helicopters, NORM is typically the safest choice.
•
We also recommend setting a gasoline engine's electronic kill switch to the OFF position in the F/S function for safety reasons.
Updating F/S Settings: If you specify a F/S setting, the FailSafe data is automatically transmitted once each two minutes.
When you choose the F/S mode, check that your settings are as desired by turning off the transmitter power switch and
verifying that the servos move to the settings that you chose. Be sure to wait at least two minutes after changing the setting
and turning on the receiver power before turning off the transmitter to confirm your changes have been transmitted.
GOAL of EXAMPLE: STEPS: INPUTS:
Battery FailSafe (F/S): a second battery low warning feature (separate from the transmitter low voltage warning). When
the airborne
battery voltage drops below approximately 3.8V, the PCM receiver’s battery F/S function moves the throttle
to a predetermined position. When the Battery F/S 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 Battery F/S function by
moving the THROTTLE STICK to idle. You will have about 30 seconds of throttle control before the battery function
reactivates.
Adjustability:
•
NOR F/S setting for throttle results in Battery F/S going to the servo position reached by moving T
HROTTLE STICK
to the
bottom with TRIM LEVER centered;
•
POS F/S setting for throttle results in Battery F/S also going to the same throttle servo position as the regular F/S.
If using a 6V (5-cell) receiver battery, it is very likely that your battery will be rapidly running out of charge before
battery FailSafe takes over. It is not a good idea to count on battery FailSafe to protect your model at any time, but
especially when using a 5-cell battery.

ACRO ADVANCE MENU FUNCTIONS:
Aircraft wing types (ACRO/GLID):
There are 3 basic wing types in aircraft models:
•
Simple. Model uses one aileron servo (or multiple servos on a Y-harness into a single receiver channel) and has a tail.
This is the default setup and requires no specialized wing programming.
•
Twin Aileron Servos. Model uses 2 aileron servos and has a tail. see Twin Aileron Servos.
•
Tail-less model (flying wing). Model uses 2 wing servos working together to create both roll and pitch control.
see ELEVON.
Twin Aileron Servos (with a tail) (ACRO/GLID): Many current generation models use two aileron servos, plugged into two
separate receiver channels. (If your model is a flying wing without separate elevators, see ELEVON, p. 48.)
Benefits:
•
Ability to adjust each servo's center and end points for perfectly matched travel.
•
Redundancy, for example in case of a servo failure or mid-air collision.
•
Ease of assembly and more torque per surface by not requiring torque rods for a single servo to drive 2 surfaces.
•
Having more up aileron travel than down travel for straighter rolls – aileron differential. (see glossary for definition.)
•
Using the two ailerons not only as ailerons but also as flaps, in which case they are called flaperons.
•
Set a negative percentage to reverse the operation of one of the servos.
Options:
•
5-channel receiver? Set up AIL-2 (see p. 47) prior to continuing with FLAPERON or AIL-DIFF.
•
FLAPERON:
•
Uses CH6 for the second servo (see AIL-2 to use CH5.)
•
Allows flap action as well as aileron action from the ailerons.
•
Provides FLAP-TRIM function to adjust the neutral point of the flaperons for level flight.
•
Also allows aileron differential in its own programming (instead of activating AIL-DIFF).
•
Aileron Differential (AIL-DIFF):
•
Uses CH7 for the 2nd servo (see AIL-2 to use CH5.)
•
Leaves CH6 free for flap operation, such as flaperon and flap action together, in AIRBRAKE. (see p. 55).
•
Allows for more up aileron travel than down for straighter rolls.
You will need to choose which is the better choice for your model's setup – FLAPERON or AIL-DIFF. If you need the ailerons
to also operate as flaps, you most likely want to use FLAPERON. If your model has 2 aileron servos and flaps, then AIL-DIFF
is probably the easiest choice. (For details on setting up a complex aerobatic plane, such as one with 4 wing servos using
full span ailerons and full span flaps, as well as AIRBRAKE/crow and other features, please visit our FAQ at
www.futaba-rc.com\faq\faq-9c.html. Many other setup examples are also available at this location.)
NOTE: Only one of the three wing-type functions (FLAPERON, AIL-DIFF, and ELEVON) can be used at a time. All three
functions cannot be activated simultaneously. To activate a different wing type, the first must be deactivated.

or ELEVON can be activated.

Set up AIL-DIFF (see p. 47) or ELEVON (see p. 48).
Using FLAPERON (ACRO/GLID):
The FLAPERON mixing function uses one servo on each of the two ailerons, and uses them
for both aileron and flap function. For flap effect, the ailerons raise/lower simultaneously.
Of course, aileron function (moving in opposite directions) is also performed.
Once FLAPERON is activated, any time you program CH6 or “flap” (ie. FLAP-ELEVATOR mixing), the radio commands both
servos to operate as flaps. The amount of travel available as flaps is independently adjustable in FLAPERON. A trimming
feature is also available (see FLAP-TRIM) to adjust both neutral positions together for straight-and-level flight or slight
increases/decreases of the flap angle. END POINT and SUB-TRIM both still adjust each servo individually.
Adjustability:
•
Each aileron servo's up travel can be set separate from its down travel, creating aileron differential. (See example).
•
Each aileron servo's travel when actuated as a flap is separately adjustable.
•
AIL2 can be utilized to use a 5-channel receiver and still have flaperons. NOTE: The AIL2 function only commands the
channel 5 servo to operate with the aileron servo as ailerons, and to obey the primary flap control (travel adjusted in
FLAP-TRIM.) It does not provide full flap mix capability as when using a 6+ channel receiver and channel 6.
NOTE: Activating flaperons only makes the ailerons work as ailerons and tells the radio how far you want them to move
as flaps IF you then activate other programming that moves them as flaps.
FLAP-TRIM is the flap-trimming feature that allows the flaps to move in reaction to the channel 6 control. It is meant only
for trimming the flaps' center but can also be used as full flap control. (See p. 46).
AIRBRAKE is a feature that drops flaperons as flaps, and also compensates with elevator if desired. (See p. 55).
FLAP-ELEVATOR would add elevator mixing into the flap movement from the flap dial after FLAP-TRIM is activated.

Using FLAP-TRIM (camber) to adjust flaperons: (ACRO/GLID)
FLAP-TRIM assigns the primary flaperon control [defaults to VR(A)] to allow trimming in
flight of the flap action of flaperons. (Note: even if FLAP-TRIM is made active with AIL-DIFF,
it will not have any effect. The ONLY function that allows control of the ailerons as flaps
in the AIL-DIFF configuration is AIRBRAKE.) Most modelers use AIRBRAKE, or programmable
mixes, to move the flaps to a specified position via movement of a switch.
FLAP-TRIM may also be used as the primary flap control in flight. By doing so, you can
assign CH6 to a 3-position switch, with a "spoileron", neutral, and "flaperon" position, and even adjust the percentage traveled
as flaperon/spoileron by changing the Flap Trim travel. (Note that there is only one setting, not independent settings for up and
down travel.)

The function is automatically activated with FLAPERON; however, the default travel is 0.
Using Aileron Differential (AIL-DIFF) (ACRO/GLID):
Aileron differential is primarily used on 3-servo wings,
with one servo operating inboard flap(s) on CH6, and
AIL-DIFF controlling proper aileron operation of 2 aileron
servos, plugged into CH1 and CH7. The ailerons can
not be moved like flaps when using AIL-DIFF, except if
using AIRBRAKE (see p. 55.) (Note that even if you make
FLAP-TRIM active while using AIL-DIFF, it will not have
any effect. ONLY AIRBRAKE controls the ailerons as
flaps in the AIL-DIFF configuration .)
*If you receive an error message that OTHER WING MIXING IS ON, you must deactivate ELEVON or FLAPERON. see p. 44.
Using Twin Aileron Servos with a 5-channel receiver,
AAIILL--22
(ACRO/GLID):
AIL-2 allows FLAPERON and AIL-DIFF with a 5-channel receiver. AIL-2 only tells the radio
that you are using CH5 and CH6, not CH6 or CH7, as the second servo in FLAPERON or
AIL-DIFF. You still must activate and set up the FLAPERON/AIL-DIFF function.
Note that selecting CH5&6 does NOT free up CH6 to be used for other functions when using a receiver with more than 5
channels. Both 5 and 6 are dedicated to the FLAPERON or AIL-DIFF programming. [This is beneficial with four aileron servos
that need to have their end points or sub-trims set separately. CH1, CH5 and CH6 are already fully set up to operate as
ailerons. Mix CH7 or CH8 (the second aileron servo on the other side) into ailerons to function properly.]

There are 4 basic tail types in aircraft models:
•
Simple. Model uses one elevator servo and one rudder servo (or multiple servos on a Y-harness). This is the default.
•
Dual Elevator servos. Model uses 2 elevator servos. see AILEVATOR (ACRO) see p. 49.
•
Tail-less model. Model uses 2 wing servos together to create roll and pitch control. see ELEVON (ACRO/GLID). see p. 48.
•
V-TAIL. Model uses 2 surfaces, at an angle, together to create yaw and pitch control. see V-TAIL (ACRO/GLID). see p. 50.
Note: Only one of the three tail-type functions (AILEVATOR, V-TAIL, and ELEVON) can be used at a time. The radio provides
a warning and will not allow the activation of another tail type until the first is deactivated. An error message of OTHER
WING MIXING IS ON will display. (See the wing type example on page 44.)
Using ELEVON (ACRO/GLID): used with delta wings, flying wings, and other tailless aircraft that combine aileron and
elevator functions, using two servos, one on each elevon. The aileron/elevator responses of each servo can be adjusted
independently. This is also popular for ground model use, such as tanks, which drive two motors together for forward, and
one motor forward/one backward for turning.
Adjustability:
•
Requires use of CH1 and CH2.
•
Independently adjustable aileron travel allows aileron differential.
•
Independently adjustable elevator travel allows for differences in up vs. down travel.
NOTE: If ELEVON is active, you cannot activate FLAPERON, AIL-DIFF, or AILEVATOR. An error message OTHER WING MIXING
IS ON displays and you must deactivate the last function to activate ELEVON.
NOTE: Be sure to move the elevator and aileron sticks to full deflection during setup. If large travels are specified, when
the A
ILERON and ELEVATOR STICKS are moved at the same time the controls may bind or run out of travel.

Dual Elevator Servos (with a rudder) (AILEVATOR) (ACRO/GLID): Many models use two elevator servos, plugged in separate
receiver channels. (Flying wings without a separate aileron control use ELEVON. V-shaped tail models use V-TAIL, p. 50.
Benefits:
•
Ability to adjust each servo's center and end points for perfectly matched travel.
•
Ease of assembly, not requiring torque rods for a single servo to drive 2 surfaces.
•
Elevators acting also as ailerons for extreme stunt flying or more realistic jet
flying (optional).
•
Redundancy, for example in case of a servo failure or mid-air collision.
Adjustability:
•
CH2 and CH8 only. (With programmable mixing, could utilize CH5 as the 2nd elevator servo.
See www.futaba-rc.com\faq\faq-9c.html for examples.) THROTTLE-NEEDLE uses CH8 and cannot be active simultaneously.
•
Direction of each servo's travel may be reversed in REVERSE or the set percentages may be reversed here.
•
Elevator travels independently adjustable (both directions and percent).
•
Optional action as ailerons (defaults to 50% response). This response cannot be activated/deactivated in flight.
Setting AIL1 and 2 to 0 disables this feature. Note: if you want this, but on/off with a switch, set AIL1 and 2 to 0 here, and use 2
mixes – AIL-to-ELEV and AIL-to-AUX2 (link/trim off, assign a switch)– to get aileron action from the elevator servos when the
assigned switch is on. See p. 59.
(For details on setting up a complex aerobatic plane, such as one with 4 wing servos, full span ailerons/flaps, AIRBRAKE/crow etc,
please visit www.futaba-rc.com\faq\faq-9c.html. Many other setups are also available.)
The AILEVATOR mixing function uses one servo on each of the two elevators, and combines the elevator function with the
aileron function (unless aileron travel is set to 0). For aileron effect, the elevators are raised and lowered opposite of one
another in conjunction with the ailerons.
Once AILEVATOR is activated, unless you zero out the aileron figures (see below), any time you move your ailerons or any
programming moves your ailerons (ie. RUDDER-AILERON mixing), the radio automatically commands both elevator servos
to also operate as ailerons. To deactivate this action, simply set the 2 aileron travel settings to 0 in the AILEVATOR function.
This way the elevators will work only as elevators.
If using the elevators as ailerons as well, be sure to move the elevator/aileron stick while checking the servo motions. If a
large travel is specified, when the sticks are moved at the same time, controls may bind or run out of travel.)

Using V-TAIL (ACRO/GLID):
V-TAIL mixing is used with v-tail aircraft so that both elevator and rudder functions
are combined for the two tail surfaces. Both elevator and rudder travel can be
adjusted independently on each surface.
NOTE: If V-TAIL is active, you cannot activate ELEVON or AILEVATOR functions. If one of these functions is active, an error message
will be displayed and you must deactivate the last function prior to activating ELEVON. see the wing example on page 44.
NOTE: Be sure to move the elevator and rudder sticks regularly while checking the servo motions. If a large value of travel
is specified, when the sticks are moved at the same time, the controls may bind or run out of travel. Decrease the travel
until no binding occurs.
Adjustability:
•
Requires use of CH2 and CH4.
•
Independently adjustable travels allow for differences in servo travels.
•
Rudder differential is not available. (To create rudder differential, set RUD1 and 2 to 0, then use two programmable
mixes, RUD-ELE and RUD-RUD, setting different percents for up and down. These are your new rudder travels. Trim and
link off, switch assignment null so you can’t accidentally turn off rudder. see PROG.MIX, p. 59.)

Snap Rolls at the flick of a switch (SNAP-ROLL) (ACRO/GLID):
This function allows you to execute snap rolls by flipping a switch, providing the
same input every time. It also removes the need to change dual rates on the 3
channels prior to performing a snap, as SNAP-ROLL always takes the servos to the
same position, regardless of dual rates, inputs held during the snap, etc.
Note: Every aircraft snaps differently due to its C.G., control throws, moments, etc.
Some models snap without aileron; others snap on elevator alone. Most models snap
most precisely with a combination of all 3 surfaces. Additionally, rate of speed and
acceleration when using the snap switch will affect how the model snaps. For
information on using gyros with airplanes for cleaner precision maneuvers, such as
snaps and spins without over rotation, see p. 64.
Adjustability:
• Travel: Adjust the amount of elevator, aileron and rudder travel automatically applied.
• Range: -120 to +120 on all 3 channels. Default is 100% of range of all 3 channels.
• Directions: Up to 4 separate snaps may be set up, one for each of the 4 direction choices (up/right, down/right,
up/left, down/left). Each snap is fully adjustable regarding travels and direction on each of the 3 channels.
Note: for simplicity, the radio refers to snaps that use “UP” or positive elevator as “U” or “UP” snaps. This is more commonly
referred to as a positive or inside snap. “D” or “DOWN” snaps are more commonly referred to as negative or outside snaps.
• R/U = Right positive R/D = Right negative L/U = Left positive L/D = Left negative snap roll
• Assignment of the 2 switches (DIR-SW1/2) to change snap directions is fully adjustable and optional. If you wish to
have only one snap, leave the switches as NULL. (If assigned, SW1 = up/down, SW2 = left/right.)
• Caution: it is critical that you remember if you assigned switches to select the three additional snaps.
• For example, assign SWITCH A for U/D snap direction, and then also assign SWITCH A for elevator dual rates. While
flying on elevator low rate (S
WITCH A DOWN
) you pull your snap S
WITCH
. The model will:
• use the throws set in the snap programming (the low rate elevator has no effect); and
• be a down (negative/outside) snap, not an up (positive/inside) snap.
• Both of these may come as a great surprise and risk crashing if you are unprepared.
• Safety Switch (SAFE-MOD): a safety may be set up on your landing gear S
WITCH, preventing accidental snap rolls while
the landing gear is down. The safety switch is turned on and off with the landing gear SWITCH.
• ON: the safety mechanism is activated when the landing gear S
WITCH
is in the same position as at the time this
feature is changed to ON. Snap rolls will not be commanded even if the snap roll SWITCH is turned on with the gear
SWITCH in this position. When the landing gear SWITCH is moved to the opposite position, snap rolls may be
commanded.
• OFF: activates the safety mechanism in the opposite position from the ON function.
• FREE: the safety mechanism is completely turned off. Snaps can be commanded regardless of the gear SWITCH POSITION.
Note: The location of the safety switch always follows channel 5. If channel 5 is reassigned to switch C, for example, switch
C is now the safety. If channel 5 is nulled or used as the second aileron servo, the safety function will not be available.
• Trainer Safety: SNAP-ROLL is automatically disabled when the trainer function is activated.

AIRBRAKE/BUTTERFLY (crow) mixing (ACRO/GLID):
Like FLAPERON and AILEVATOR, AIRBRAKE is one function that is really made up of a series of pre-programmed mixes all
done for you within the radio. AIRBRAKE (often called “crow” or BUTTERFLY - see GLID, p. 69 for details) simultaneously
moves the flap(s) (if installed), twin ailerons (if installed) and elevator(s), and is usually used to make steep descents or to
limit increases in airspeed in dives.
This function is often used even on models without flaps as an easy way to use the flaperons and FLAP-ELEVATOR mixing together.
Adjustability:
• Activation: Proportional by moving the THROTTLE STICK, or set positions by flipping SWITCH C (ACRO only).
• Lnear (Inversely proportional to THROTTLE STICK): provides a proportional increase in amount of AIRBRAKE action as
THROTTLE STICK is lowered (when SWITCH C (ACRO) or A (GLID) is in down position). Provides gradually more
AIRBRAKE as you slow the engine. Includes selectable stick position where AIRBRAKE begins, gradually increasing to
the same setting as MANUAL as the THROTTLE STICK is lowered. If you would like to have the airbrake be directly
proportional to throttle stick, you will need to reverse the THR-REV function. Note that this changes the throttle stick
direction for all mmodels. See page 31 for instructions.
• MANUAL (ACRO only): Provides AIRBRAKE response immediately upon switch movement, going to a pre-set travel on
each active channel without any means of in-flight adjustment. (MANUAL option not available in GLID modes.)
• Delayed reaction: You can suppress sudden changes in your model's attitude when AIRBRAKE is activated by setting
the delay (DELAY-ELE) item, to slow down the elevator response, allowing the flaps/ailerons/elevator to all reach their
desired end point together. A setting of 100% slows the servo to take approximately one second to travel the
prescribed distance.
• Adjustable in flight: Using the elevator trim lever in flight will adjust the elevator settings in your airbrake rather than
adjusting the model's actual elevator trim. This allows easy adjustment for any ballooning while in flight. When the
airbrake switch is moved to off the trims are again adjusting the normal elevator trim.
• Channels controlled: Elevator(s), twin ailerons and flap(s) may be set independently in AIRBRAKE, including set to 0
to have no effect.
• Twin aileron servos: If FLAPERON, ELEVON and AIL-DIFF functions are inhibited, then AIL1 and AIL2 settings will have
no effect.
• If FLAPERON is active, the travel of the ailerons can be independently adjusted for the servos plugged into CH1
and CH6. The flap choice has no effect on the flaperons.
• If AIL-DIFF is active, then CH1 and CH7 may be independently adjusted.
• Normally both ailerons are raised equally in AIRBRAKE, and the elevator motion is set to maintain trim when
the ailerons rise. Different amounts may be set for each aileron to correct for torque reactions and other unique
characteristics of the model.
Be sure you understand what dropping ailerons will do when in AIRBRAKE/BUTTERFLY. Along with creating an
enormous amount of drag (desirable for spot landings), this also creates "wash-in", a higher angle of attack where
the ailerons are, and encourages tip stalling. If you are using this for aerobatic performance and not "sudden stops",
consider raising the ailerons and dropping the flaps instead as shown in the diagram above.
• Twin elevator servos:
• If AILEVATOR is active, the AIL1 and AIL2 settings still only affect FLAPERON or AIL-DIFF servos, NOT the
elevator servos. (they would have the AIL3 and AIL4 settings.)

THROTTLE-NEEDLE is a pre-programmed mix that automatically moves an in-flight
mixture servo (CH8) in response to the THROTTLE STICK inputs for perfect engine tuning
at all throttle settings. This function is particularly popular with contest pilots who fly in
a large variety of locations, needing regular engine tuning adjustments, and requiring
perfect engine response at all times and in all maneuvers. Also popular to minimize
flooding at idle of inverted engine installations or installations with a high tank position.
Not needed for fuel injection engines, which do this automatically.
Adjustability:
• Five-point curve allows adjustment of engine mixture at varied throttle settings.
• The in-flight mixture servo must connect to receiver CH8.
• In-flight mixture servo may also be used as a second servo for tuning a twin.
• Throttle cut feature also moves the in flight needle servo.
• The CH8 knob adjusts the high throttle mixture (may be deactivated. see AUX-CH).
• Because both use CH8, this function cannot be used simultaneously with AILEVATOR.
• An acceleration (ACCE) function (ACRO only) helps the engine compensate for sudden, large amounts of throttle input
by making the mixture suddenly richer, then easing it back to the proper adjustment for that throttle setting. This
function requires some adjustment to best fit your engine and your flying style. Adjust engine’s response until no
hesitation occurs on rapid throttle input.
• Separate curves are available (HELI only) for normal, idle-ups 1 and 2 combined, and idle-up 3. Immediately below
THR-NEEDLE the radio displays the curve you are editing; ex: >NORML; and then which condition is currently active by
your switches ex: (ID1/2). Note that you can edit the mix for a different condition without being in that condition, to
allow editing without having to shut off the helicopter’s engine every time. Be sure you are editing the proper curve
by checking the name after the > and not the one in parentheses.
