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.

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 receivers 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 THROTTLE 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. 49.) 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. 48) 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 CH5 & CH6 free for flap operation, such as flaperon and flap action together, in AIRBRAKE. (see p. 56). 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 B 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. GOAL of EXAMPLE: De-activate FLAPERON so that AIL-DIFF or ELEVON can be activated. STEPS: Open the FLAPERON function. INPUTS: for 1 second.(If basic, to FLAPERON. De-activate the function.

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. 50. Tail-less model. Model uses 2 wing servos together to create roll and pitch control. see ELEVON(ACRO/GLID). see p. 49. V-TAIL. Model uses 2 surfaces, at an angle, together to create yaw and pitch control. see V-TAIL (ACRO/GLID ). see p. 51. 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] When changing the polarity of a rate, "change rate dir?" is displayed for a check. Please set up after pressing DIAL for 1 second and canceling an alarm display. (GLID only)
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 AILERON and ELEVATOR STICKS are moved at the same time the controls may bind or run out of travel. (For details on setting up a complex aerobatic plane, such as "space shuttle" style controls, please visit www.futaba-rc.com\faq\faq-9c.html. Many other setup examples are also available at this location.) GOAL of EXAMPLE: Activate ELEVON. Adjust aileron down travel to 90% of up travel, creating aileron differential. STEPS: Open the ELEVON function. INPUTS: for 1 second. (If basic, to ELEVON. Activate the function. Optional: adjust the up/down travel separately for the servos as ailerons. (Ex: down to 90%.) Optional: adjust the elevator travel of each servo. (Ex: right servo elev. travel to 98%, left to 105%.) Close menu. Where next? AILERON STICK. AILERON STICK to 98%. to 105%. to 90%. to 90%.

Be sure you understand what dropping ailerons will do when in AIRBRAKE/BUTTERFLY. Along with creating an enormous amount of drag (desireble for spot landings), this also creates "wash-in", a higher angle of attack where the ailerons are, and cncourages 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 avobe.
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 mixing (ACRO/HELI): 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 engines 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 helicopters engine every time. Be sure you are editing the proper curve by checking the name after the > and not the one in parentheses. GOAL of EXAMPLE: STEPS: INPUTS: Activate THROTTLE-NEEDLE mixing.

THROTTLE DELAY (ACRO):

The THROTTLE DELAY function is used to slow the response of the throttle servo to simulate the slow response of a turbine engine. A 40% delay setting corresponds to about a one-second delay, while a 100% delay takes about eight seconds to respond. For helicopters, see DELAYS, p. 92.
This function may also be used to create a slowed servo on a channel other than throttle. This is accomplished by plugging the desired servo (Ex: gear doors) into CH3 (THR), throttle into an auxiliary channel such as 8, and then using some creative mixes. Please see our Frequently Asked Questions area at www.futaba-rc.com\faq\faq-9c.html for this specific example.

LINEAR PROGRAMMABLE MIXES (PROG.MIX1-5):
Your 9C super contains five separate linear programmable mixes (ACRO and GLID. HELI has 2). (Note that mixer #6-7s mixing RATEs are set with a 5-point curve. see CURVE MIXES, p. 63.) There are a variety of reasons you might want to use these mixes. A few are listed here. All of the adjustable parameters are listed below, but dont let them scare you. For your first few times experimenting with mixes, just turn on the default mixes, adjust them how you think they need to be, then use the servo screen to check and see if you were correct. As with all functions, a sample setup follows, step by step, to assist you. Sample reasons to use linear programmable mixes: To correct bad tendencies of the aircraft (such as rolling in response to rudder input). To operate 2 or more servos for a single axis (such as two rudder servos). To automatically correct for a particular action (such as lowering elevator when flaps are lowered). To operate a second channel in response to movement in a first channel (such as increasing the amount of smoke oil in response to more throttle application, but only when the smoke switch is active). To turn off response of a primary control in certain circumstances (such as simulating one engine flaming-out on a twin, or throttle-assisted rudder turns, also with a twin). Adjustability: ACRO/GLID Defaults: The 5 programmable mixes default to the most frequently used mixes for simplicity. If you want to use one of these mixes, simply select that mix number so that the master and slave servos are already selected for you. (HELI mixes default to ail-to-rudd and elev-to-pitch.) PROG.MIX1 aileron-to-rudder for coordinated turns PROG.MIX2 elevator-to-flap for tighter loops PROG.MIX3 flap-to-elevator to compensate pitching with flaps PROG.MIX4 throttle-to-rudder ground handling compensation PROG.MIX5 rudder-to-aileron roll coupling compensation Channels available to mix: All five mixes may use any combination of CH1-8. (CH9 is not proportional and cannot be mixed.) Offset and dials may also be set to the master channels. (see below.) Master: the controlling channel. The channel whose movement is followed by the slave channel. Another channel: Most mixes follow a control channel. (Ex: rudder-to-ailerons, 25%, no switch, corrects roll coupling.) MASTER SLAVE LINK TRIM SWITCH POSITION RATE OFFSET RUDD AILE ON OFF ANY NULL 25% 0 Offset as master: To create an OFFSET mix, set the master as OFST.

Glider1FLAP Configuration
Glider2FLAP/2FL-C Configuration
Before doing anything else to set up a glider or sailplane, first you must decide which MODEL TYPE best fits your aircraft. ACRO: for some aerobatic/slope gliders, ACRO is a better choice because of functions it offers that the GLID types do not. ACRO provides: SNAP-ROLL, AILEVATOR (twin elevator servo support), AIRBRAKE (a more assignable version of BUTTERFLY). For nitro-powered sailplanes: IDLE-DOWN, THR-CUT, THROTTLE-NEEDLE mixing and THROTTLE DELAY programming. But ACRO lacks programming for full-span ailerons and START and SPEED OFFSETS. GLID1FLAP: The GLID1FLAP MODEL TYPE is intended for sailplanes with one or two aileron servos (or none), and a single flap servo (or two connected with a y-connector). This TYPE is meant to be a very simplistic version to set up a basic glider without a lot of added features. Full-span ailerons are not possible in this MODEL TYPE. GLID2FLAP/GLID2FL-C: The GLID2FLAP/GLID2FL-C MODEL TYPE supports dual flap servos that can also act as ailerons, creating full-span ailerons and flaps. Additional flight conditions available (GLID2FL-C only). These flight conditions contain different offset trims and aileron differentials to make the sailplane perform certain maneuvers more easily. NOTE: This is one of the several functions that the radio requires confirmation to make a change. GOAL of EXAMPLE: Change model 1 is MODEL TYPE to GLID1FLAP. NOTE: This is one of the several functions that the radio requires confirmation to make a change.

If a single servo is not operating properly, REVERSE: see p. 31. If a control is operating backwards (i.e. Elevator), see SWASH AFR, p. 84. If unsure see SWASH AFR.
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.
SWASH AFR (not in SWH1): Swashplate function rate settings (SWASH AFR) reduce/increase/reverse the rate (travel) of the aileron, elevator (except SWH2 ) and collective pitch functions, adjusting or reversing the motion of all servos involved in that function, only when using that function. Since these types utilize multiple servos together to create the controls, simply adjusting a servos REVERSE or END POINT would not properly correct the travel of any one control. Since SW1 uses one servo for each function, there is no need for AFR in SW1. This is fairly hard to explain but easy to see, so let's set up Kyosho Caliber's swashplate settings as an example. With everything installed per factory instructions, set the model to HELI(SR-3). Now let's adjust the swashplate properly. Since aileron always uses no more than 2 servos, check it first. Either both operate properly (no change needed), both operate backwards (reverse the whole function), or one servo operates backwards (reverse that servo alone). Next check elevator. Remember, the aileron servo(s) operate correctly, so if elevator does not, we should only have 2 choices left the whole function needs to be reversed, or the servo(s) not shared with aileron need to be reversed. Last is collective. If aileron and elevator are working properly, the only thing that could be wrong is the whole direction collective operates (reverse the whole function). In our example, SR-3 is 180 degrees off from the swashplate of the Caliber. Therefore, it is very likely that several functions will not operate properly. The collective pitch operation is backwards; but reversing all three servos would also reverse the aileron and elevator operations. Changing the collective pitch rate, however, from +50% to -50%, will reverse the collective pitch without affecting the aileron action.

TH-CV/NOR: inputs the normal (NORM) throttle curve, which is usually not a linear response to THROTTLE STICK motion. Adjusting point 3 of the curve adjusts the engines RPM at the THROTTLE STICK midpoint the desired position for hovering. The other 4 points are then adjusted to create the desired idle and maximum engine speed, and a smooth transition in-between. For more on throttle curves, see p. 90. PI-CV/NOR: inputs the normal (NORM) collective pitch curve, the collective pitch curve for flight near hover. The normal collective pitch curve is adjusted to match the throttle curve, providing the best vertical performance at a constant engine speed, with a starting curve of 4 base, +5 neutral, and +8 to +10 degrees of blade pitch maximum*. You can program the response over a 5-point curve for the best collective pitch angle relative to THROTTLE STICK movement. For more on collective pitch curves, see p. 90. REVO./NOR: mixes collective pitch commands to the rudder (a PITCH-RUDDER mix) to suppress the torque generated by changes in the main rotor's collective pitch angle, keeping the model from yawing when throttle is applied. REVO. is extremely helpful in taming the tail of models not using heading-hold/AVCS gyros. NOTE: There are three revo. mixes available: normal (NORM), idle-up 1 / 2 (IDL1/2), and idle-up 3 (IDL3). All 3 are adjustable in the ADVANCE menu. Never use revo. mixing in conjunction with heading-hold/AVCS gyros.For details on revo, including default points for clockwise and counterclockwise rotating rotors, see p. 90.
*These default recommendations assume you are doing forward flight. If you are just learning, please follow your instructors guidance. Some instructors like a +1 base point for training so that the helicopter comes down very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.
GOAL of EXAMPLE: Set up Normal Flight Condition Throttle/Collective Pitch Curves and Revo. Base point: Adjust base point of throttle curve until engine idles reliably on ground. Adjust base point of collective pitch curve to achieve 4 degrees of blade pitch. Apply throttle until the model sits light on its skids. Adjust base point of REVO. until model does not rotate its nose at all. Hover point: Adjust collective pitch curve to +5 degrees. Ease heli into a hover. Land/shut engine off. Adjust throttle curves and rudder trim. Repeat until model hovers smoothly at half throttle. Rapidly apply throttle from to stick. Adjust REVO. points 2 and 3 until the model does not rotate its nose up on throttle application. High point:Adjust collective pitch curve to +8 to +10 degrees. From hover, throttle up rapidly. If engine bogs, increase the throttle curve. If engine over-revs, increase the collective pitch curve at points 4 or 5. Apply full throttle while hovering, then descend back to hover. Adjust REVO. until the nose does not change heading. Where next?

*(These default recommendations assume you are doing forward flight. If you are just learning, please follow your instructors guidance. Some instructors like a +1 base point for training so that the helicopter comes down very slowly, even if your instincts pull the throttle/collective stick to the bottom in a hurry.)
Adjustability: Normal condition curves are editable in the BASIC menu for convenience. All curves may be adjusted in the ADVANCE menu. Automatically selected with the proper condition. The idle-up curves are programmed to maintain constant RPM even when the collective pitch is reduced during flight (including inverted). To change which conditions curve is being edited, cursor up above point 1 and change the curve named. For clarity, the name of the condition currently active (switched on in the radio) is shown in parentheses behind name of condition whose curve is being edited. (Example: see curve displays below. Note that the normal condition is active but the idle-up 1 conditions curves are currently being edited. Idle-ups and throttle hold pitch curves may be edited even before the conditions have been made active. Activating their throttle curves activates these conditions.
REVO. MIX: This 5-point curve mix adds opposite rudder input to counteract the changes in torque when the speed and collective pitch of the blades is changed. Adjustability: Three separate curves available: normal for hovering; idle-ups 1 and 2 combined; and idle-3. Normal condition curves are editable in the BASIC menu for convenience. All curves may be adjusted in the ADVANCE menu. Correct mix is automatically selected in-flight with each condition and automatically activated when the throttle setup for that condition is activated in the programming (i.e. THROTTLE HOLD or THR-CURVE.) To change which conditions curve is being edited, cursor up above POINT1 and select. For clarity, the name of the condition currently active (switched on at the radio) is shown in parentheses behind the name of the condition whose curve is being edited.
Revo. mixing rates are 5-point curves. For a clockwise-turning rotor, the rudder is mixed in the clockwise direction when collective pitch is increased; for counterclockwise-turning, the opposite. Change the operating direction setting by changing the signs of the numbers in the curve from plus (+) to minus (-) and vice versa. Suggested defaults: Clockwise rotation: -20, -10, 0, +10, +20% from low throttle to high. Counterclockwise rotation: +20, +10, 0, -10, -20% from low throttle to high. Adjust to the actual values that work best for your model. Revo. curves for idle-ups are often v-shaped to provide proper rudder input with negative pitch and increased throttle during inverted flight. (Rudder is needed to counter the reaction whenever there is increased torque. In inverted flight, throttle stick below half has increased throttle and negative pitch, therefore increasing torque and rotating the helicopter unless the revo. mix is also increasing appropriately.)

The relationship of the governor speed setting rS1~rS3 and the switch positions conforms to the table above. In throttle hold, always check that the governor is off. If the speed value rises when the cut switch is activated, reverse the DIR setting from +LIMIT to -LIMIT or vice versa.
GOAL of EXAMPLE: Set up a GV1 governor to use both channels into the receiver and switch between the governor settings automatically when changing conditions. Consider setting the battery FailSafe settings and other helpful functions on the GV-1 itself.

Always pay particular attention to the flying fields 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, dont 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 wont 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 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 Built-in programming which defaults outboard ailerons as flaperons and sets up two flap servos to also operate as flaperons for a 4-trailing-edge-surface wing.
If you are using a glider or heli MODEL TYPE, please go to that chapter now to select the proper model type and support your model setup. Note that changing MODEL TYPE resets all data for the model memory, including its name.
GOAL of EXAMPLE: STEPS: Select the proper MODEL TYPE for your Open the BASIC menu, then open the model. Ex: ACRO. PARAMETER submenu.

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: Decrease the flap servo throw in the Open END POINT function. for 1 second. (If ADVANCE, again.) upward direction to 5% to allow to END POINT. trimming of level flight only and down travel to 85% to prevent binding. Choose proper channel and set to flap. direction.

Move auxiliary channels 5-9 to different dial(s)/switch(es)/slider(s): see p. 39. Set up IDLE-DOWN and THR-CUT to slow/cut the engine: see p. 33. Set up dual/triple rates and exponential (D/R,EXP): see p. 35. Set up flight timers: see p. 38. Set up trainer functions: see p. 40. Set up twin aileron servos: see p. 44. Set up twin elevator servos: see p. 49. to 85%.
*You can reset to the initial values by pressing the DIAL for one second.
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 springloaded 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: Decrease the throttle setting at idle with the flip of a switch for spins and landings. STEPS: Open BASIC menu, then open IDLEDOWN function. Activate the function. With THROTTLE STICK at idle, adjust the rate until engine idles as desired.* Optional: change switch assignment. Choose desired switch and position. Close. THR-CUT: see p. 34.

TRAINER: for training novice pilots with optional trainer cord connecting 2 transmitters. The instructor has several levels of controllability. Adjustability: 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 any programming set at the student's transmitter. FUNC: When the TRAINER SWITCH is ON, the channel set to this mode can be controlled by the student, controlled according to any 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 is controlled by the instructor only, even when the TRAINER SWITCH is ON. SWITCH: controlled by spring-loaded SWITCH F (9CA) or H (9CH) only. Not assignable. Compatibility: The 9C may be master or student with any Futaba FM transmitter compatible with the cord. Simply plug the optional trainer cord (For 9C series, sold separately) into the trainer connection on each transmitter, and follow the guidelines below.
Examples: When throttle/collective are set to FUNC, 5-channel helicopter practice is possible with a 4-channel transmitter. Set up the model in a second transmitter, use NORM mode to quickly and safely check proper operation of all functions, then allow the student radio to fully fly the model. Using NORM mode, set lower throws, different exponentials, even different auxiliary channel settings on the student radio (if it has these features). To ease the learning curve, elevator and aileron may be set to the NORM or FUNC mode, with the other channels set to OFF and controlled by the instructor. Precautions:
NEVER turn on the student transmitter power. ALWAYS set the student transmitter modulation mode to PPM. BE SURE that the student and instructor transmitters have identical trim settings and control motions. Verify by switching back and forth while moving the control sticks. FULLY extend the instructor's antenna. Collapse the student's antenna. Always remove the student transmitter's RF module (if it is a module-type transmitter). When the TRAINER function is active, the snap roll function is deactivated. Other functions, such as IDLE-DOWN and

End cycling and close. Set up dual/triple rates and exponential (D/R,EXP): see p. 35. Set up desired programmable mixes: see p. 54. Set up dual aileron servos: see p. 44. Set up dual elevator servos: see p. 49.
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: Change the receiver FailSafe command for channel 8 (gasoline engine kill switch) to a preset position. NOTE: This is one of several functions for which the radio requires confirmation to make a change. STEPS: Open the BASIC menu, then open F/S function. Choose Channel to change. (ex: Ch. 8) Set and confirm fail safe command. INPUTS: for 1 second. (If ADVANCE, to F/S. to Ch 8. that controls channel 8 to desired OFF position. for 1 second to store. Repeat as desired. Close. Where next? Wait two minutes and confirm F/S settings as described above. Read below for information on Battery FailSafe. Adjust END POINTs to gain proper F/S responses if needed: see p. 32. Adjust SUB-TRIM to gain proper F/S responses if needed: see p. 41.

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. GOAL of EXAMPLE: Activate twin aileron servos, FLAPERON. Input 10% less down travel than up travel (aileron differential) within the FLAPERON programming. (Decrease right ailerons down travel to 90%, decrease left aileron's down travel to 90%.) Adjust total flap travel available to 50% of aileron travel available. Where next? STEPS: Open the FLAPERON function. Activate the function. Optional: adjust the up/down travel separately for the 2 servos.(Ex: 90% down.) Optional: adjust the aileron's travel so they move as flaps. (Ex: each servo flap travel to 50%.) Close menu. Set FLAP-TRIM: see p. 46. Set up AIRBRAKE mix: see p. 55. Mix flaperon's flap motion to another inboard flap (plugged into aux1): see p. 54.

* If you receive an error message that OTHER WING MIXING IS ON, you must deactivate AIL-DIFF or ELEVON. see p. 44.

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 AILERON and ELEVATOR STICKS are moved at the same time the controls may bind or run out of travel. (For details on setting up a complex aerobatic plane, such as space shuttle style controls, please visit www.futaba-rc.com\faq\faq-9c.html. Many other setup examples are also available at this location.) GOAL of EXAMPLE: Activate ELEVON. Adjust aileron down travel to 90% of up travel, creating aileron differential. STEPS: Open the ELEVON function. Activate the function. Optional: adjust the up/down travel separately for the servos as ailerons. (Ex: down to 90%.)

Special Additions, Functions, And Added Equipment Commonly Used On Powered Aircraft Gyros: Just as torque rotates an aircraft on the runway during take-off, helicopters struggle with torque twisting the model every time throttle is applied. For many years gyroscopes have been used on model helicopters to control this. In competition aerobatics and scale aircraft competition alike, the usefulness of gyros has recently come to light. For in-depth information on gyro types, please see p. 89. For aerobatics, gyros on rudder and elevator fix over-rotation of snaps and spins as well as tail wagging in stall turns. (Futaba offers a twin-axis gyro, GYA-352, that controls two axes with a single gyro.) For 3D aerobatics (below stall speed, such as torque rolls), heading-hold/AVCS gyros on rudder and elevator dramatically simplify these maneuvers. For scale models, gyros are frequently used to simplify take-offs and landings by keeping the model straight during throttle application. Always be careful if using a heading-hold/AVCS gyro, as it will correct any change in yaw that is not caused by movement of the rudder (like making a turn with just aileron and elevator). Typically, modelers use headinghold/AVCS settings only for specific maneuvers, such as take-offs and torque rolls, then switch to normal mode or OFF for the remainder of the flight to avoid this risk. While the 9Cs ACRO/GLID programming does not offer gyro-specific programming, simply adjusting the END POINTs of the channel that is used to control the gyros gain will adjust the gyros performance in flight. For details on gain and other gyro functions, please see the HELI GYRO programming, p. 89. Retracts: Retractable landing gear is often used on scale models for increased realism and on high performance models to decrease drag. The gear servo is typically plugged into CH5, which defaults to a 2-position switch for simplicity. Mechanical retracts require the use of a specialized non-proportional retract servo. Retract servos go from full travel one direction to full travel the other direction, then mechanically hold the gear into the locked position. A regular servo used for mechanical retracts will continue to draw full power the entire time, prematurely draining the battery and risking crash of your model. End point will not adjust a retract servo. Pneumatic (air driven) retracts use a standard servo to control an air valve which directs air into or out of the retract units, moving the gear up or down. Pneumatics are easier to install but require added maintenance of the air system. Gear Doors: Some scale models with retracts also have separate gear doors to cover the scale gear. For one example of how to operate the gear doors separately from the retracts, please visit our website: www.futaba-rc.com\faq\faq-9c.html. Smoke Systems: Many scale and aerobatic models use smoke systems to provide increased realism or a more impressive demonstration. There are many smoke systems available, with varying types of control. Most use a servo to increase/decrease the flow of smoke fluid into the specialized smoke muffler. The oil is heated in the muffler, creating smoke. It is a good practice to set up a safety that shuts off the smoke oil if the throttle is lowered below half-stick. For a detailed example of a smoke system setup, please visit our website: www.futaba-rc.com\faq\faq-9c.html. Kill Switches: For safety reasons, it is strongly recommended that an electronic kill switch be installed in all gasolinepowered aircraft. In case of any type of in-flight problem (such as prop failure, exhaust vibrating off, throttle servo failure, radio interference), the modeler can shut the engine off quickly and safely in flight. Additionally, FailSafe (F/S) settings are recommended to shut the engine off in case of sufficient interference to trigger the PCM FailSafe settings. Lastly, an electronic kill switch set to off prior to the aircrafts power being shut off adds an additional safety should someone accidentally turn on the mechanical kill switch on the exterior of the model. Bomb Drops, Paratroopers, and other Released Items: Many sport and scale models include one or more of these fun add-ons. Typically, all are controlled by a simple micro-switch plugged into CH9. The switch is assigned in AUX-CH.

Change the receiver modulation from FM (PPM) to PCM or vice versa: see p. 28. 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.
GLIDER ADVANCE MENU Varied wing types and tail types (twin aileron servos, twin elevator servos, elevon, v-tail, etc). See p. 44-50 for basic information. FLAPERON (GLID1FLP only): 2 aileron servos operate in opposite directions as ailerons and same direction as flaps. See p. 45. FLAP TRIM: provides camber movement or trimming of flaperons as flaps. See p. 46. For sailplanes, this function is also used as wing camber. The amount depends on the model, but usually a small amount (less than 10%) is preferred, since too much camber produces excess drag. Dont use more than about 1/16 travel up or down for glider camber. Some airfoils, such as the RG-15, should be flown with NO reflex/camber. Be sure to consult your models manual for guidelines. Note that even though you may make FLAP-TRIM active while using 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.) Aileron Differential (AIL-DIFF): allows twin aileron servos to provide differential down travel from up travel. See p. 47. Using a 5-channel receiver with FLAPERON and AIL-DIFF. See AIL-2, p. 47. ELEVON: for flying wings. See p. 48. V-TAIL: for models with 2 servos operating together to create roll and pitch control. See p. 50. AILEVATOR: not available in GLID model types. Mixes: Linear Programmable mixes (PROG.MIX1-5): fully assignable programmable mixes with a linear response. see p. 59. Curved Programmable mixes (PROG.MIX6-7): fully assignable programmable mixes with a curved response. See p. 62. ELEV-FLAP: pre-programmed mix creates elevator movement from the inboard flaps as well as elevators. See p. 54. BUTTERFLY: Often called crow, BUTTERFLY is the glider version of AIRBRAKE. (BUTTERFLY does not have the option to activate it solely from a switch, and its activation switch is not assignable. BUTTERFLY may only be turned on/off by SWITCH A, and always provides progressively more BUTTERFLY as the CHANNEL 3 (THROTTLE) STICK is lowered, or raised if used THR-REV, p. 31.) See AIRBRAKE, p. 55.
Full Span Mixing: Flap-to-Aileron and Aileron-to-Flap FLAP-AILE (GLID2FLP only): This pre-programmed mix is used to create full span flap action on a glider with 4 wing servos. This changes the camber over the entire wing, which produces less drag than just dropping the flaps by themselves. Since FLAP-AILE and AILE-FLAP are generally utilized together, one example is shown below setting up both. NOTE: When you have ELEV-FLAP mixing also, the trailing edge droops with the elevators, increasing pitch response. Adjustability: RATE range of -100 to +100. Negative setting would result in up flaperon with down flap and vice versa. OFFSET range of 30 to +30. Setting offset position sets the flap position at which the flaperons are neutral. Intended for models that do not have the flaps positioned neutral at the flap servos center. (ie. down travel only) SWITCH A-H fully assignable. POSITION fully assignable, including NULL (mix always on) and Up&Cntr and Cntr&Dn to activate the mix in 2 separate positions of the same SWITCH. (This allows easy setup of one SWITCH position which is no FLAP-AILE or AILE-FLAP mixing, one with both FLAP-AILE and AILE-FLAP mixing, and one with just FLAP-AILE mixing.)

GOAL of EXAMPLE: Set up a SPEED OFS to gain maximum possible lift on launch. Each Aileron: 5%. Each Flap: 3%. Elevator: -1% to compensate.
STEPS: Open SPEED OFS function.

GETTING STARTED WITH A BASIC HELICOPTER This guideline is intended to help you set up a basic (SWH1) heli, to get acquainted with the radio, to give you a jump start on using your new radio, and to give you some ideas and direction on how to do even more with this powerful system than you may have already considered. It follows our basic format of all programming pages a big picture overview of what we're trying to accomplish; a by name description of the steps to help acquaint you with the radio; and then a step-bystep instruction to leave out the mystery and challenge of setting up your model. Briefly, the typical helicopters controls are as follows: Aileron: changes cyclic lateral (roll). Rolls the helicopter. Tilts the swashplate to the left or right. CH1. Elevator: changes cyclic pitch. Changes the helicopters angle of attack (nose up or nose down). Tilts the entire swashplate fore and aft. CH2. Rudder: changes the angle of the tail rotor. Yaws the helicopter left or right. CH4. Collective Pitch: adjusts main rotor collective [angle of the paddles], changing the main blades pitch. Increased collective pitch (with throttle) causes the helicopter to rise. Moves in conjunction with throttle on the THROTTLE STICK. CH6. Throttle: opens/closes carburetor. Moves in conjunction with collective pitch on the THROTTLE STICK. CH3. REVO: mix that adds rudder in conjunction with pitch. This helps compensate for rotation of the helicopter caused by the increased engine torque. (Never use revo. mixing with a heading-hold/AVCS gyro; the gyro already does this.) For additional details, see that function's section in this manual the page numbers are indicated in the first column for you.
GOAL of EXAMPLE: Prepare your helicopter.
STEPS: INPUTS: Install all servos, switches, receiver per your model's instructions. Set all trims, dials and sliders to neutral. Confirm all control linkages are 90 degrees (or per instructions) from the servo horn to the ball link for proper geometry and that no slop is present. Mechanically adjust all linkages to get as close as possible to proper control throws and minimize binding prior to radio set up. In the BASIC menu, open the PARAMETER submenu. Turn on the transmitter. for 1 second.(If ADVANCE, then Go to MODEL TYPE. Select proper MODEL TYPE. Ex: HELI(SWH1). Confirm the change. Close PARAMETER. In the BASIC menu, open the MODEL submenu. to TYPE. to HELI(SWH1). sure? displays. for 1 second. to confirm. to choose PARAMETER.

GYROS and GOVERNORS: Using electronics to take some of the complexity out of setups and flight. What is a gyro? A gyroscope is an electronic unit that senses motion and corrects for it. For example, if the wind blows your helicopters tail to the left, a gyro will sense that motion (and confirm that no input was given) and will correct for it. How does it help in helicopter setup? A good gyro will totally eliminate the need for revo. mixing. The gyro will sense and correct the unwanted motion for you, so you dont have to spend time to get a complex curve operating properly. Gyro sensor kinds: There are many different kinds of gyros. Early gyros were mechanical, with a spinning drum similar to a childs gyroscope toy. The next generation utilized a special type of crystal, called piezoelectric, which sensed the motion and provided an electrical pulse. The finest gyros at the time of this writing are SMM technology. These silicone micro machines, or computer chips, sense the motion. SMM is far more accurate and less susceptible to inaccuracies caused by temperature changes, etc. Types of gyro responses: Normal: sense motion and dampen it (if the gyro rotates off course for 2 seconds, it corrects for 2 seconds). Heading-hold/AVCS: calculate the angle of rotation (by tracking the time/rate of change) and then provide correction until the same rotation is achieved. Stick priority: a feature on most high-end gyros. The more input given on the channel the gyro controls, the less sensitive the gain is automatically. This way, if you give a large input for a stall turn, for example, the gyro turns itself off and does not fight the stall turn. As you ease off the rudder, the gain increases again, minimizing tail wag and keeping the model straight. (If your gyro does not include stick priority, you can manually create it. Please see www.futaba-rc.com\faq\faq-9c.html.) Choosing the right gyro for your skills, your helicopter, and your budget: Mechanical: some are still available. They are very challenging to set up and not as reliable as piezo or SMM. Non-Heading-Hold Piezo: these are now inexpensive gyros that are reliable and easy to set up. Some have dual rates and remote gain control to adjust sensitivity in flight. Lack heading-hold capabilities for precision flying. Heading-Hold Piezo: Until recently, the cream of the crop. Expensive, and more complex to set up. Adds GPS-like heading recognition. Exhibits minor difficulties with temperature drift (position setting varying with units temperature). Heading-Hold SMM: 21st Century gyro technology. Computer chip technology. Expensive, easier set up, higher durability. Significant decrease in temperature sensitivity. Many include frame rate settings to allow faster response when using specialized digital servos. Examples: GY401: Simpler set up. Ideal for learning aerobatics through 3D. GY502: Better centering than 401 for more advanced aerobatics. Ideal through Class III competition. GY601: Exceptional center. Extremely fast response time. Requires specialized servo. GYRO: simplifies adjusting/selecting the gyro sensitivity, and can provide more than 2 gyro gain settings. (The higher the gain, the more correction the gyro provides and the softer or less responsive the helicopter feels.) This function makes the best possible use of the inflight adjustable gain of most gyros. Adjustability: Plug the gyros sensitivity adjustment to channel 5 of the receiver. (not assignable) STD and AVCS/Heading-hold (GY) setup types available to simplify adjustments for AVCS/Heading-hold gyros. Full switch assignability or may select Cond. option. Cond. option provides separate gyro settings, one for each condition, automatically selected with the condition. Allows changes in gain to meet the specific needs of each flight condition. Each gyro setting may be set from 100 to +100 gain, equating to ATV settings of 100% to +100%. Dual mode gyros (heading-hold/AVCS and normal) are easily triggered to each mode by changing the gyro settings sign. Negative settings trigger normal mode; positive settings are AVCS mode. Larger percentages indicate more gain, or gyro responsiveness. Tail wagging or shaking indicates excessive gain settings. Turn down gyro setting until wag stops.

Technical Specifications.9 Thermal hunting setup: using specific programming setups to have the model respond noticeably to the lift of a thermal. Not a preprogrammed mix. See Programmable mix. THR-DELAY: (ACRO) throttle delay, slows engine servo response to imitate the spool-up action of a turbine engine. May also be used creatively to create a delayed servo on a different function (see www.futaba-rc.com\faq\faq-9c.html.).57 THR-REV: reverses the throttle trim function to the top of the THROTTLE STICK.31 THROTTLE-NEEDLE: (ACRO / HELI) curve mix that adjusts a second servo, controlling the engines mixture, to get optimum RPM and performance from the engine at all settings.56 Throttle-to-rudder mix: used to compensate with rudder when throttle is applied on take off. Not a preprogrammed mix. See Programmable mix. This is the default setting of a mix in ACRO and GLID. THROTTLE CURVE: (HELI) adjusts how the servo responds to the THROTTLE STICK position along a 5 point curve. Separate curves available for each idle-up and normal. For simplicity, normal curve may be edited from BASIC menu. All curves may be edited together in the ADVANCE menu. Activating an idle-ups throttle curve is what activates that idle-up.81,84 Throttle cut or throttle kill: THR-CUT. (ACRO / HELI) Offset mix which closes the throttle servo to a set position when the assigned switch is moved to shut the engine off without having to fiddle with trim settings.33 THROTTLE HOLD: (HELI) makes the throttle servo non-responsive to THROTTLE STICK position, and moves the throttle to idle. Used to practice autorotations. NOTE: THR-HOLD must be activated, then the default pitch curve adjusted properly.83 Throttle trim adjustment: see ATL to change throttle trim from idle only to full trim control like all other channels. See THR-REV to reverse THROTTLE STICK completely, including moving trim to the top of the THROTTLE STICK. See also Idle management for details on idle down and throttle cut functions. TIMER: adjust the timer functions, used to keep track of flight time on a tank of fuel, etc. The trigger to turn timers on/off may be programmed.38 TP-FM: single-frequency module. See Module. TRAINER: software that allows 2 radios to be connected via trainer cord, giving student control of all or some of the channels of the aircraft at the flip of a switch. FUNC trainer mode allows student to use mixing in the master transmitter, for example dual rates, exponential, fly a 5-channel helicopter with a 4-channel buddy box, etc.40 Trainer box: stripped-down radio system which does not have the ability to transmit, is used only as a students radio when instructing while using a trainer cord and the trainer programming. Trainer cord: cord used to connect two compatible radios to use for flight instruction. See Accessories. TRIM menu: adjusts rate at which the trim responds to movement of the trim sliders. Also has a reset function to reset the models electronic trims to zero.41 TRIM OFFSET: (HELI) sets an offset or adjustment of trim when switching between conditions. See OFFSET. TRIM option in mixes: ability to adjust the slave servos center when the master servos center is adjusted using the trim sliders (for example when using two separate flap servos). See Programmable mix.53 Triple rate: 3rd control travel setting available in flight. See D/R,EXP. Twin aileron servos: use of 2 or more servos on separate channels to control aileron action. Includes flaperon, aileron differential, and elevon.44 Twin elevator servos: use of 2 or more servos on separate channels to control the elevator of a model. Includes elevon, ailevator, V-tail.49 Tx: transmitter. Voltmeter, voltage reading: displays transmitter voltage on home screen.18 VR(A-E): variable rate controls. Knobs and sliders on the radio. See switch assignment chart for default assignments.
