Repeat above steps for elevator and rudder. Close. Where next? Set up flight timers: see p. 36. Set up TRAINER functions: see p. 37. Adjust the sensitivity of the trims: see p. 38. Set up twin aileron servos: see p. 42. Set up programmable mixes to meet your specific needs: see p. 53.
TIMER submenu (stopwatch functions): controls an electronic clock used to keep track of allowed time remaining in a competition, flying time on a tank of fuel, amount of time on a battery, etc.
Adjustability: Count down timer: starts from the chosen time, displays time remaining. If the time is exceeded, it continues to count below 0. Count up timer: starts at 0 and displays the elapsed time up to 99 minutes 59 seconds. Independent to each model, and automatically updates with model change. In either TIMER mode, the timer beeps once each minute. During the last twenty seconds, there's a beep each two seconds. During the last ten seconds, there's a beep each second. A long tone is emitted when the time selected is reached. To Reset, choose the desired timer with the SELECT key (while at the startup screen), then press and hold DIAL for 1 second. Activation by either direction of SWITCH A-H, by STICK (1-4). THROTTLE STICK is convenient if you are keeping track of fuel remaining, or for an electric, how much battery is left. To quickly reset any timer from the home screen, cursor down until the timer blinks. Press dial to reset.
GOAL of EXAMPLE: Set timer to count down 4-1/2 minutes, being controlled by THROTTLE STICK position. This is utilized to keep track of actual Throttle on time to better correlate with fuel/battery usage.

Battery FailSafe (F/S ): A second battery low warning feature (built into the 2.4GHz receiver). When the airborne battery voltage drops below approximately 3.8V, the 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 Fail Safe to protect your model at any time, but especially when using a 5-cell battery.
ACRO ADVANCE MENU FUNCTIONS: Aircraft wing types (ACRO): 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): 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. 44.) 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.

Options: 5-channel receiver. Set up AIL-2 (see p. 42) in FLAPERON. FLAPERON: Uses CH6 for the second servo (see AIL-2 to use CH5 orCH7.) 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.
Channel 6 = normal flaperons, 2 servos operate together as flaps; Channel 5 or 7 = act like aileron differential did in prior radios; channel 6 is still FLAPS, and the 2 ailerons never act together as flaps EXCEPT in the airbrake function.
NOTE: Only one of the two wing-type functions (FLAPERON and ELEVON) can be used at a time. Both functions cannot be activated simultaneously. To activate a different wing type, the first must be inhibited. GOAL of EXAMPLE: De-activate FLAPERON so that ELEVON can be activated. STEPS: Open the FLAPERON function. INPUTS: for 1 second.(If basic, to FLAPERON. Inhibit the function. Close function. Where next? Set up ELEVON (see p. 44). to INH.

Using FLAPERON (ACRO):

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. 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. Second aileron servo (AIL-2): The default for the second aileron servo is CH6 and this allows both servos to work as ailerons and flaps. If CH5 or CH7 is selected the flap function only works CH6, and the two aileron servos function only as ailerons except in the air brake (A. BRAKE) function. In the air brake function the flap servo CH6 and the aileron servos CH1 and (CH5 or CH7) work together.
GOAL of EXAMPLE: Activate twin aileron servos, FLAPERON. Input 10% more up travel than down travel (aileron differential) within the FLAPERON programming.
STEPS: Open the FLAPERON function.
INPUTS: for 1 second. (If basic, * to FLAPERON.

Adjustability: Requires use of CH1 and CH2. Independently adjustable aileron/elevator travel. Adjustable aileron differential.
NOTE: If ELEVON is active, you cannot activate FLAPERON or AILVATOR. You must inhibit the last function to activate ELEVON. NOTE: Be sure to move the elevator and aileron sticks to full deflection during setup. If a large amount of travel is specified, when the AILERON and ELEVATOR STICKS are moved at the same time the controls may bind. (For details on setting up a complex aerobatic plane, such as "space shuttle" style controls, please visit www.futaba-rc.com\faq\faq-7c.html. Many other setup examples are also available at this location.) GOAL of EXAMPLE: Activate ELEVON. Adjust aileron differential to +10%. Activate the function. Optional: adjust the aileron differential. (Ex: +10%. ) Optional: adjust the aileron/elevator travel as desired. Where next? Close menu.

STEPS: Open the ELEVON function.
INPUTS: for 1 second.(If basic, to ELEVON.

to +10%.

(Elevator travel) (Aileron travel)
Dual Elevator Servos (with a rudder) (AILEVATOR) (ACRO): 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. 51. 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: 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 AIL3 and 4 to 0 disables this feature. Note: if you want this, but on/off with a switch, set AIL3 and 4 to 0 here, and use 2 mixes AIL-to-ELEV and AIL-to-AUX2(assign a switch) to get aileron action from the elevator servos when the assigned switch is on. 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 amount of travel is specified, when the sticks are moved at the same time, the controls may bind.)

HELICOPTER MODEL FUNCTIONS Please note that nearly all of the BASIC menu functions are the same for airplane (ACRO setup) and helicopter (H-1/H-2/HR3/HN3/H-3/HE3) setups. The features that are identical refer back to the ACRO chapter. The Helicopter BASIC menu includes the normal conditions throttle and collective pitch curves and revo. mixing.

GETTING STARTED WITH A BASIC HELICOPTER This guideline is intended to help you set up a basic ( H-1 ) 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 helicopter's 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 helicopter's 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 which is in headinghold/AVCS mode. However, revo. mixing is still used when a heading-hold/AVCS gyro is in normal mode.) 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 and dials 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. Turn on the transmitter. for 1 second.(If ADVANCE,

Confirm Gyro direction. (Note: if using a heading-hold/AVCS gyro, use the GYRO programming for proper setup.) See p. 73.
With radio on, move helicopter's tail to the right by hand. The gyro should give right rudder input (leading edge of the tail rotor blades move left). If the gyro gives the opposite input, reverse direction on the gyro unit itself.
Be sure to follow your model' s instructions for preflight checks, blade tracking, etc. Never assume a set of blades is properly balanced and will track without checking. Check receiver battery voltage! Always check voltage with a voltmeter prior to each and every engine start. (Never assume being plugged in all night means your radio gear is ready to fly). Insufficient charge, binding servo linkages, and other problems can result in a dangerous crash with the possibility of injury to yourself, others and property. Confirm the swashplate is level at 0 travel. Adjust arms if needed. Apply full collective and check that the swashplate remained level and there is no binding. Repeat for full cyclic pitch and roll. If not, adjust as needed to correct in END POINT: see p. 31. Important note: prior to setting up throttle hold, idle-ups, offsets, etc., be sure to get your normal condition operating properly. Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and having completed all range checks, etc, gradually apply throttle until the helicopter becomes "light on the skids." Adjust trims as needed to correct for any roll, pitch, or yaw tendencies. If the tail "wags," the gyro gain is too high. Decrease gyro gain.

Rudder-to-throttle and other programmable mixes p. 53.

Periodically move the throttle stick to full and back down to ensure proper servo settings. It is critical that VR dials be centered when the pitch and throttle curves are setup.
HELI-SPECIFIC BASIC MENU FUNCTIONS MODEL TYPE: This function of the PARAMETER submenu is used to select the type of model programming to be used. Before doing anything else to set up your model, first you must decide which MODEL TYPE best fits your aircraft. If your transmitter is a 7CA, the default is ACRO. If it is a 7CH, the default is HELI(H-1). HELICOPTER SWASHPLATE TYPES: The 7C radios support 6 basic swashplate setups, including "single servo" (H- 1 - most helicopters use this type) and 5 types of CCPM (cyclic and collective pitch mixing). A "single servo" swashplate uses one servo for each axis: aileron, elevator (cyclic pitch), and collective pitch. CCPM helicopters utilize a combination of servos working together to achieve the 3 axes of motion. There are 5 basic CCPM types, displayed below. CCPM has several advantages, the most obvious of which is far less mechanical complexity to properly move the swashplate of the helicopter. Additionally, several servos working in unison (ex: HR3, all 3 servos together create elevator movement) dramatically increases the torque available as well as the precision and centering. Please note that some helicopters are type HR3 or HN3, except off by 180 degrees. For example, the Kyosho Caliber is HR3 but with the 2 parallel servos to the rear of the helicopter, not front. If your model's swashplate is off by 180 degrees, you will still use that swashplate type, but also use SWASH AFR (p.63) to adjust the functions as needed until it operates properly. Additionally, different angles of CCPM may also be created utilizing the fully assignable programmable mixes. (See our Frequently Asked Questions area at www.futaba-rc.com\faq\faq-7c.html for specific examples.) Not operating quite like you expected? In many CCPM installations you need to either reverse the direction of a specific function (SWASH AFR) or reverse a single servo's direction (REVERSE). See SWASH AFR for details.(p.63) Swashplate Type Setting Procedure HELI H-1 Type: Independent aileron, pitch and elevator servos linked to the swashplate. Most kits are H-1 type. HELI H-2 Type: Pushrods positioned as shown. Elevator operates with a mechanical linkage. With Aileron input, the aileron and pitch servos tilt the swashplate left and right; with Pitch input, the aileron and pitch servos raise the swashplate up and down.

to -23%.

Close the menu. Confirm the swashplate is level at 0 travel. Adjust arms if needed. Apply full collective and check that the swashplate remained level. If not, adjust servo's travels as needed to correct. END POINT: see p. 31. Set up the normal condition: (TH-CV/NOR, PI-CV/NOR, REVO./NOR): see p. 65. Set up D/R,EXP: see p. 33.
Setting up the Normal Flight Condition: The Normal flight condition is typically utilized for hovering. The throttle and collective pitch curves are adjusted to provide consistent engine RPM despite the increase/decrease in collective pitch of the blades. This keeps the engine from "bogging down" under excessive load (like trying to accelerate a car on a steep hill in 5th gear) or excessive RPM under insufficient load (like flooring the throttle while in neutral), risking engine damage. As the 2 curves and revo. mixing are all interrelated, we will discuss all three first, then complete a sample setup. Note that the normal throttle and pitch curves and revo mix are all available in the BASIC menu for simplicity. These may also be updated later in the ADVANCE menu with the settings for the other 3 conditions [idle-up 1 (IDL1), idle-up 2 (IDL2) and throttle hold (HOLD)]. Note: The throttle and pitch curves for the normal condition are always on. They cannot be inhibited. The other three conditions are activated with their throttle curves or throttle hold. For idle-ups, see p. 69. For throttle hold, see p. 67.
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 engine's 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. 69. 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. 69. REVO.: 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. Never use revo. mixing in conjunction with a heading-hold/AVCS gyro while in heading-hold/AVCS mode. Revo. mixing is still used with these gyros while set to the normal mode. For details on revo, including default points for clockwise and counterclockwise rotating rotors, see p. 69.

Note: Be sure to add the step of setting a trigger point by cursoring to THR, then putting the THROTTLE STICK in the desired position and pressing and holding the dial for one second. Notice that this function cannot be reversed to trigger only above the stick point.
HELI-SPECIFIC ADVANCE MENU FUNCTIONS THR-HOLD: This function holds the engine in the idling position and disengages it from the THROTTLE STICK when SWITCH E (7CH) or G (7CA) is moved. It is commonly used to practice auto-rotation.
Prior to setting up THR-HOLD, hook up the throttle linkage so that the carburetor is opened fully at high throttle, then use the digital trim to adjust the engine idle position. To have THR- HOLD maintain idle, move the THROTTLE STICK to the idle position, then move the hold SWITCH on and off and keep changing the offset value until the servo does not move. To lower the engine idle speed, or if you want to shut off, input a more negative number. Adjustability: Idling position: Range of -50% to +50% centered about the throttle idle position to get the desired engine RPM. Rudder offset: Offsets the tail rotor pitch. Keeps the fuselage from rotating in throttle hold. Switch assignment: Assigned to SWITCH G (7CA) or E (7CH) down. Not adjustable. Throttle curve: Since the throttle is moved to a single preset position, no curve is available for THR-HOLD. Collective pitch curve: Independent curve, typically adjusted to create a blade pitch range of -4 to +6 to +12, is automatically activated with THR-HOLD. Revo. mix: Since revo. mix adjusts for torque from the engine, no revo. mix is available for THR-HOLD. Priority: The throttle hold function has priority over idle-up. Be sure that the throttle hold and idle-up SWITCHES are in the desired positions before trying to start the engine. (We recommend starting your engine in throttle hold for safety reasons.)
GOAL of EXAMPLE: Set up throttle hold.
STEPS: Open THR-HOLD function.
INPUTS: for 1 second.(If basic, to THR-HOLD.
Determine desired throttle position by idling engine, turn on THR-HOLD, and adjust percentage as required to reach the desired running point.
Activate the function. Set desired engine position. Optional: set up a rudder offset. Close. to OFF.
to OFF. to desired percent. to desired offset.
PIT-CURVE for THR-HOLD: see p. 68. GYRO setup: see p. 73. Setting up the Idle-Ups: Throttle and Collective pitch Curves and Revo. Mixing (TH-CURVE, PIT-CURVE, REVO. MIXING) for idle-ups: see p. 69. D/R,EXP: see p. 33.
THR-CURVE and PIT-CURVE: These 5-point curves are utilized to best match the blade collective pitch to the engine RPM for consistent load on the engine. Curves are separately adjustable for normal, idle-up 1 and idle-up 2. In addition, a separate collective pitch curve is available for throttle hold. Sample curves are displayed in the appropriate setup types (ex: normal flight condition, p. 65) for clarity. Suggested defaults: Normal: Collective pitch curve that results in points 1, 3 and 5 providing -4, +5, (+8 to +10)* degrees pitch. A throttle curve setting of 0, 30, 50, 70, 100%. Idle-up 1: Idle-ups 1 is typically the same except for the gyro settings, with heading-hold/AVCS mode. The pitch curve will likely be similar to the normal curve above. Idle-up 2: Collective pitch curve that results in points 1, 3 and 5 providing (-8 to -10), 0, (+8 to +10) degrees. A throttle curve of 100, 75, 50, 75, 100 to provide full throttle for inverted maneuvers. Throttle Hold pitch curve: Start with the normal pitch curve (for inverted autos, start from the idle-up 2 pitch curve), but increase the last point approximately 1-2, if available, to ensure sufficient pitch at landing.

GOAL of EXAMPLE: Activate SWASH-THR mixing. Adjust mixing amount (AIL-N) to 10%.
STEPS: Open the SWASH-THR function.
INPUTS: for 1 second.(If basic,
to SWASH-THR. Activate the function. Adjust the mixing amount as needed. (Ex: 10%)

GYROS and GOVERNOR: 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 don' t 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 child' s 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-7c.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 unit's 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 gyro's 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. Each gyro setting may be set from 0 to 100% gain. Dual mode gyros (heading-hold/AVCS and normal) are easily triggered to each mode by changing the gyro settings sign. 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 THR-REV: Reverses the throttle trim function to the top of the THROTTLESTICK.30 Throttle-to-rudder mix: Used to compensate with rudder when throttle is applied on take off. Not a preprogrammed mix. See Programmable mix. 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-up's throttle curve is what activates that idle-up.65,68 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.32 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.67 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.
