Insert the connector such as sensor, servo, connection cord, battery
etc. surely.
*If it is not securely inserted all the way in, it may come off due to vibration during light
and there is a danger of falling.
ABOUT WIRING:
Please ix at the appropriate position so that the continuing cord
rub against the corner of the metal or carbon frame and the covering
will not break.
ABOUT VIBRATION ISOLATION AND WATERPREEFING:
The CGY760R is fixed with a dedicated mounting pad with good
condition and the helicopter performs sufficient anti-vibration measures so as not to receive strong vibration at the time of light. Also, if
there is a risk of watering, place it in a plastic bag and take waterproof
measures.
ON FLIGHT PRECAUTION:
Always exit programming mode before attempting to ly the model.
.Gyro operating precautions:
Gyro
The CGY760R requires 5-10 seconds to initialize when the power is
turned on. Do not move the helicopter and do not move the tail rotor,
aileron and elevator sticks during this initialization or the gyro may not
initialize properly. Once the initialization process has been completed
the swash servos and tail servo will move several times indicating that
the CGY760R is now ready for light.
13
Verify that the gyros are operating and compensating in the correct
direction before each light. If the compensation direction is incorrect
on any axis the model will become uncontrollable after takeoff.
The servo type parameters within the CGY760R must match the type
of servo you are using. Incorrect setting may damage the CGY760R or
the servos, possibly resulting in a loss of control during light.
Always allow the gyro to adjust to the surrounding environmental
temperature before light. A large temperature change during use will
cause drift and other operational issues.
If you are switching between Normal Mode and AVCS Mode in light,
please keep in mind that you must have the gyro re-learn the center
position after making a trim change within the transmitter. To memorize
the new center position simply lip the gain switch on the transmitter
three times between Normal Mode and AVCS Mode (Normal
AVCS
Normal AVCS) within one second. The servo will center indicating
that the new center position has been memorized.
When operating the gyro in AVCS Mode, all compensation and revolution mixing must be disabled and any tail rotor or swash offsets for
light modes must be disabled.
Do not drop the CGY760R onto a hard surface or subject the
CGY760R sensor to a strong shock as this may damage the sensor.
Verify that the gyro is operating in the desired mode.
When the CGY760R is operated in AVCS mode the tail rotor or
swash plate servos will not center when tail rotor, aileron or rudder
stick is released. This is normal operation for AVCS mode. The servos
may also move to the extent while the model is being carried out to the
light line. Before take off, you must visually center the tail rotor pitch
slider and level the swash plate by using the transmitter control sticks.
You can also center the servos by moving the tail rotor stick full left,
then full right, back to full left and then allow the stick to center within
one second; the same method applies for aileron and elevator servos.
14
Never turn off the CGY760R while the GX (gyro) LED is blinking
green at high speed (about 5 / sec).
*If you turn off the power while high-speed blinking, setting changes can not be saved
and data errors may occur.
.Governor operating precautions:
Governor
When the throttle servo is connected to the CGY760R, the battery
failsafe function within the CGY760R must be setup and enabled.
Throttle fail safe function (transmitter setting): Use the fail safe function for the channel that turns the governor on and off to set the fail
safe position to the point at which the governor is turned off. With this
setting, when the system enters the fail safe state, the governor will be
turned off, and the receiver throttle signal (fail safe position preset) will
be output directly.
When using the condition hold function on the transmitter, always
set the throttle servo maximum operating point to less than the point
at which the governor is activated. If this is not done the governor may
activate while in condition hold.
While preparing for light or starting the engine, always ensure the
throttle remains below the governor activation point and do not select
any light modes that may activate the governor.
If you prefer to activate the governor while the model is still on the
ground, always ensure that you have at least -5 degrees of pitch in the
model before activating the governor. This negative pitch is necessary to prevent an unexpected lift off as the governor activates and the
head speed increases to the desired RPM.
Be sure to set the autorotation to the OFF side with the governor ON
/ OFF switch function.
Periodically check the RPM sensor output to ensure proper governor operation. Due to the high level of vibration and centrifugal forces
the magnet may come loose or the sensor alignment may change. Ev-

ery 10th light verify that the magnet and sensor are properly mounted.
If abnormality such as vibration etc. is recognized on the aircraft
side during operation, be prepared to turn off the governor immediately.
MACHINE MAINTENANCE:
WARNING
Even though the CGY760R is a high performance gyro and governor,
it will be necessary to ensure that the helicopter mechanics are also in
optimum operating condition. Please use the guidelines below and address all issues before installing and lying the CGY760R.
Mount on a model using the attached mounting pad and mount it at the center position of model gyro mount so that it is exactly orthogonal to the roll and pitch axis of
the aircraft.
*The CGY760R should be mounted on a rigid platform, at least 6in [152mm] away from a
Nitro Engine. It is not necessary to mount the gyro near the main shaft of the model but it is
very important that the mounting area chosen is rigid. Please refer to your model manufacturer’s
instructions for recommended mounting locations.
Test it the gyro sensor, ensuring that the sensor is in alignment with the model on the roll and
pitch axis. The cable from the gyro sensor must exit toward the front or the rear of the model
since this is the pitch axis. Any misalignment will cause a loss of performance.
Mounting angle
• The bottom of the CGY760R Gyro Sensor must be
perpendicular to the main shaft.
• The CGY760R must be used with a rigid tail rotor drive system. Any modern torque tube or belt drive system should be adequate. Do not attempt to
ly the CGY760R using a wire driven tail rotor system.
•The roll axis must be parallel to the tail boom and
the pitch axis must be perpendicular to the side
frame.
• Always ensure the drive gears, torque tube, pulleys, belt, bearings and
shafts are in proper working condition. If any of these items are damaged or
worn they must be replaced.
• The linkage rod, tail rotor bell crank, pitch slider and tail rotor grips must
operate without friction to obtain the best performance from the CGY760R.
Binding in the tail rotor control linkage will decrease the performance of the
CGY760R gyro and this may also shorten the servo lifespan. Please take
the time now to ensure the tail rotor system on your helicopter is working
correctly and without friction or binding.
Control axis
• Rudder (Yaw) axis
• Vibration will affect the CGY760R’s overall performance. All rotating components on the helicopter should be balanced to minimize vibrations in light.
Ensure that your engine or electric motor is running smoothly and that all vibrations have been addressed before installing and test lying the CGY760R
• Elevator (Pitch) axis
• Aileron (Roll) axis

Mounting The CGY760R
The CGY760R can be mounted in the orientation shown below unless it is installed
so that the roll and pitch detection axis are aligned with the model. However, if there
is a deviation of 1/2 or more of the degree, performance will degrade. In this step,
please pay special attention to ensure optimum light performance. Refer to the installation example below and select the gyro mounting direction with "Gyro Set Dir" (page
45) of the SWH basic menu.

*Please ix the cord connected to the main body with a margin.
Please install the CGY760R as it is in the center (vertical direction and horizontal
direction) of the tape without cutting the attached mount pad. This tape is designed to
effectively absorb the vibration from the model.
*Clean the oil on the bottom of the CGY760R and the machine mounting part with a
vacuum cleaner or the like.
*The CGY760R is designed to be screwed to the gyro mount. Please refer to the end
of this manual for ixing method of screws and notes on installation.
The CGY760R Cant Be Mounted TROUBLESHOOTING
If any issues are noted during light (such as drifting, inconsistent hold or inconsistent
control rates) then please review the following troubleshooting recommendations.
1. Always verify that the tail rotor and swash plate mechanisms operate, and that the
drive system is in proper working order.
2. Electromagnetic interference could be causing the problem. If you feel everything is
set up correctly and that the model is vibration free, then consider moving the gyro
sensor to a new location away from servos, ESC and drive motors.
3. Vibrations will decrease the performance of all gyro systems. Even though the
CGY760R gyro sensor is the most vibration resistant gyro sensor available, eliminating
vibrations will always improve performance. The CGY760R gyro sensor performs best
when the sensor is mounted rigidly to the airframe. This is mainly due to the sensing
of all 3 axes. It is highly recommended to avoid using soft foam pads as this may allow
the gyro to bounce around on the roll and pitch axis, causing instabilities and possible
loss of control during light.so that the roll and pitch sensing axis are in alignment with
the model. Any misalignments over 1/2 of a degree will cause a loss in performance.
Please take extra care in this step to ensure the optimum light performance.
Using The CGY760R With A Electric Model
DANGER
Once the ESC is connected to the CGY760R, you need to complete all necessary
transmitter settings (ATV / EPA / REV / ETC) according to ESC instructions. Please
refer to page 109 of this manual for further suggestions on the use of the governor of
CGY760R and the electric model.
Link Method With Transmitter (FASSTest / T-FHSS)
1. Connect the CGY760R and GPB-1 and set the same mode as the transmitter linking
the CGY760R communication mode on the “Receiver” screen. (See page 40)
2. Keep the transmitter and receiver close to each other and turn on the receiver with the
transmitter in the link mode.
3. Wait for link waiting about 2 seconds after turning on receiver power.
4. If the RX LED changes from red lashing to green lighting, the link is complete. (The
link wait state ends in about 1 second.)
* Refer to the transmitters operation manual for complete details on how to place the
transmitter into the linking mode.
* When many FASSTest systems are turned on near the FASSTest system or when
many T-FHSS systems are turned on near the T-FHSS system, the CGY760R establishes a link to the transmitter It may be dificult. This is rare. However, if another
FASstest transmitter / receiver is linked at the same time, the CGY760R may link to
the wrong transmitter. If you do not notice such a situation, this is very dangerous.
To avoid this problem, we strongly recommend that you reconirm if the CGY760R is
actually controlled by the transmitter.
* If the System Type of the transmitter is changed, the receiver will need to be re-linked
to the transmitter.
WARNING
Do not perform the linking procedure while the motor’s main wire
connected or the engine is operating as it may result in serious injury.
When the linking is complete, please cycle the receiver power and
ensure the receiver is properly linked to the transmitter.
Please power up your system in this order. Transmitter irst, followed by the receiver.
It is necessary to remove the pinion gear from the electric motor or
disconnect the motor from the ESC before powering the model up for
setup or bench testing. Electric motors are extremely powerful and
capable of delivering the power instantly, causing injury to yourself,
others, or the surroundings.
If the CGY760R was previously linked to another transmitter, make
sure that transmitter is not operating while linking the receiver to the
new transmitter.

Magnet Operating Side Check
S.BUS Channel Setting
The default CGY760R S.BUS channel assignments should work properly with most
Futaba transmitters. If you experience any problems please refer to the S.BUS section
of the manual to set / verify each channel number for each function.
1. The SBUS basic menu (page 44) of CGY760R is displayed.
Bring the magnet near the end of the sensor and check the operating side.
*This is the side at which the displayed value increases in the "Revolution sensor testing"
menu within the "Governor Basic Setting" section earlier in this manual. Install the magnet with this side facing the sensor. Mark this side of the magnet with a felt tip pen.

2. Use the [ /+] or [ /-] key to select "AIL CH #" and press the [Enter] key to enter setting
mode. Check the transmitter’s aileron channel and set it to match the channel with the [
/+] or [ /-] key. When you are done, press [Enter] key to exit setting mode.
3. Perform the same operation as above and set the function (such as aileron, pitch, collective, gain, ail gain, ele gain, rpm, gv on/off) channels to the transmitter.
4. If your transmitter does not offer enough channels to operate all of the CGY760R’s
functions, it is possible to operate the CGY760R without the Gov SW, Ail Gain, and
Ele Gain channels connected. When any these functions are not used, it is necessary
to set the channel number to "INH" within the CGY760R’s S.BUS menu to disable the
function and to use the setting value inside the CGY760R menu instead.
When the Gov SW channel is not used, the governor on/off control is handled by the
[Stick Switch] function.
Cooling Fan Modiication
1. Drill a hole in the fan at the magnet mounting position. Make the hole about 4.1mm in
diameter and 1.5 to 1.7mm deep.
2. Embed the magnet in this hole in the direction in which an output is obtained. Use epoxy adhesive that cures in 30 minutes or longer. Do not use epoxies that contain metal
such as JB Weld.
Cement the magnet to the cooling fan so that the magnet is
level with this side of the cooling
fan.
Magnet
Governor Installation
Modify the cooling fan and install the accessory magnet and attach the magnetic sensor to the engine at the position shown below. Balance the cooling fan as needed following magnet installation.
Cooling fan
Magnet (Embedded in cooling fan.)
Sensor (Attached to engine lange through a stay.)
3. If the cooling fan is unbalanced and vibrates, etc., balance it by mounting the spare
magnet to the opposite side of the cooling fan in the opposite polarity (so that it does
not output a signal).
When installing the sensor magnet to the mufler side, also
refer to the needle side mounting.
Sensor Mounting
The sensor mounting method depends on the model and engine.
1. Mount the sensor to the sensor stay. (Temporary assembly)
2. Drill a hole in the fan cover at the part corresponding to the sensor so that the distance
between the sensor and magnet can be made 1 to 2mm.
24
25
3. Tighten the sensor stay together with the engine mounting
lange. (Temporary assembly)
Throttle Servo Linkage Precautions
· To effectively use the governor, observe the following precautions when connecting the
servo linkage.
4. Select the mounting method so that the sensor does not touch
the frame, or other parts of the model. Temporarily mount the
sensor and select the magnet mounting position.
· Make the servo operating range as wide as possible. Make the throw of the transmitter
EPA (ATV) function and AFR function as close as possible to 100%.
5. Install the sensor to the sensor stay using the accessory
screws and washers.
· Fly with the governor turned OFF and adjust the needle so that the engine smoothly
reacts to movement of the transmitter stick.
6. Tighten the sensor stay together with the engine using the
engine mount screw.
· If there is a point at which the reaction of the engine is considerably different due to a
too rich or too lean mixture, the governor may not operate to its maximum potential.
Fuselage Vibration Countermeasures
Sensor Adjustment
1. Adjust the sensor position to obtain a sensor output of at least 60% in the "Revolution
sensor testing" menu within the "Governor Basic Setting" .
Center of sensor
is offset.
Sensor
Use Of A Tuned Silencer
Sensor case
Magnet
1 - 2mm
If the model frame is weak, or the engine mount is deformed or not installed properly, the vibrations applied by the engine will increase. Engine vibrations will lead
to unstable speed and prevent the governor from providing maximum performance.
Therefore, make sure that the engine is vibration free and that the carburetor provides
linear throttle control because the governor cannot correct engine problems.
The use of a tuned pipe type silencer may cause the engine throttle response to be
substantially different from that of a normal muffler. Adjust the needle (and pipe
length) so that engine speed changes are proportional to the throttle opening. The
governor will not perform satisfactorily with a mufler or a pipe that does not allow
the carburetion to be linear.
2.2mm
3.7mm
3.7mm
2. The center of the sensor is different from the center of the sensor case so be careful
when mounting the sensor.
If the display is less than 60% when the magnet is directly below the sensor, bring the
sensor closer to the magnet so that the 60% or more is displayed. The magnet and
sensor gap criteria is approximately 1 to 2mm. If a sensor output is not obtained even
when the sensor is brought close to the magnet, the magnet and sensor center positions may have changed.
3. Complete assembly of the sensor by securely tightening the screws that were temporarily tightened.
4. Recheck the sensor output.

longer operate and the tail servo will always center when the tail rotor
stick is released. Always exit setup functions before attempting to ly the
model. Before each light always ensure that the gyros are operating and
compensating in the correct direction. The Servo Limit parameter within
the CGY760R is used to set the mechanical limits for the tail rotor servo.
To obtain the best performance it is recommended to set the limit in the
CGY760R to 100% for both directions and then adjust the servo arm
length to set the mechanical endpoints. After that has been completed
use the servo limit parameter to make small adjustments that could not be
made mechanically. Values between 90% and 110% are considered optimal. Hold the cursor to "Srv.Limit" by pressing the [ /+] or [ /-] key. Gradually move the rudder stick to the left or right by the maximum amount the
" " cursor moves. Enter the setting mode by pressing the [Enter] key,
increase or decrease the maximum throw using the [ /+] or [ /-] key, and
then press the [Enter] key to exit the setting mode. Set the same way on
the other side. Make sure that the pitch slider does not restrain beyond the
maximum movement amount.

*50% is a good starting point for rudder gain regardless of model size.
Always level the swash plate using the cyclic stick before applying throttle
and spooling the main rotor blades up. During takeoff small corrections may be
necessary. If you make large corrections while the helicopter is on the ground, it
may tip over since the helicopter is irmly on the ground and the gyros are overcompensating due to the lack of movement.
Some helicopters may have a tendency to resonate/shake during spool up.
Always leave the helicopter on the ground until this resonance or shaking goes
away. If this issue continues, it is recommended to try some rubber skid stops or
take off from a softer surface such as grass. Vibrations contribute to this ground
resonance. Verify that everything on your model is balanced correctly.yond the
linkage operating range, there is a danger of servo or helicopter being
damaged.
ADJUSTMENTS DURING THE TEST FLIGHT
Pre-light checklist
Check that the transceiver's battery is fully charged.
Check whether the gyro tape is torn or peeled.
Turn on the transmitter / receiver and initialize the gyroscope.
Check whether the servo type setting matches the servo being used (ladder /
swash).
Check that the servo horn is neutral and perpendicular to the push rod. (Ladder /
Swash).
Even if each rudder is manipulated to the maximum, it is confirmed whether
there is a stroke of the servo operation (ladder / swash).
Check that the gyro is operating in the correct mode (AVCS or normal) (ladder /
aileron / elevator).
Check whether the operation of each rudder matches the operation of the tail rotor / swash plate.
When rotating the aircraft body, make sure that corrective action is performed in
the correct direction.
Is the gyro sensitivity set correctly for all light conditions? Also, check whether
it is operating in the correct mode (AVCS or normal).
74
*When the CGY760R is used with a ESC or BEC and a power switch is not used
there is a possibility that the intermittent connection as you connect the light battery may cause the CGY760R initialization to fail. Always ensure that the gyro has
initialized properly by verifying that the gyros are compensating as the helicopter
is moved. It is recommended to use a power switch on the power supply line to
avoid this possibility.
Rudder Gyro Trim Flight:
The tail rotor/rudder AFR or D/R function within the transmitter is used to adjust the
pirouette rate of the helicopter to suit your requirments. Do NOT use ATV or rudder
channel travel adjustment for this purpose. For optimum performance, the tail rotor
should be trimmed in Normal/Rate mode as closely as possible with adjustments to
the tail rotor pushrod length before inalizing with transmitter trim and then memorizing that value into the CGY760R.
The tail rotor gyro gain should be raised until the tail begins to oscillate quickly (also
called tail "wag"). Once this point has been achieved, reduce the gain as needed a few
percent at a time to eliminate the oscillation. Repeat the process for all light conditions. The main rotor speed, tail rotor ratio, tail rotor pitch range and tail blade length
play a large part in achieving optimum tail rotor performance. The gain value can
vary drastically from model to model, and the exact value should not play a part in
the evaluation of the gyro’s performance.

TIPS FOR USING THE GOVERNOR WITH ELECTRIC MODELS
WARNING
TX AILERON / ELEVATOR GYRO GAIN SET-UP
TX Set-up for adjusting cyclic gains via the transmitter.
Using the Remote Gain Functions (roll, pitch and yaw)
Safety Reminder: Remove both main and tail blades from the model and/or
disengage the motor’s pinion from the main gear before proceeding with any
electric governor set up.
Make sure your ESC is conigured for external governor use. Refer to the owner’s manual for your ESC.
You may use either a brushless phase sensor or the traditional governor magnetic
sensor with a magnet mounted in a collar on the main shaft or in the main gear.
With one magnet, set the gear ratio to 1:1.
When choosing a brushless phase sensor, observe the input signal range of the
CGY760R speciied in the Governor Basic section.
Refer to the manufacturer’s documentation for your electric motor to select the
correct pole count when using a brushless phase sensor. Pole count is set to 2
when using a magnetic sensor.
Set the governor Working Mode (Wrk.Mode) to "GOV EXPERT" menu.
Set the servo type (ServoTyp) to DG:1520.
Make sure you correctly calibrate your ESC.
Make sure you calibrate the governor speed ranges in the transmitter’s governor
menu and set the high and low limits for throttle in the Governor Basic menu.
If a tail "kick" or "jerk" is observed when switching from one idle-up headspeed
to another, INCREASE the Revolution Up and Down delays (Revo.Up Dlyo/
Revo.Dn Dly – "GOV. EXPERT" Menu). Increase 2-5% at a time until the tail
"kick" is suppressed.
The greater the electronic speed control headroom built into the model as a function of its gearing, the more prone the tail will be to kicking with aggressive lying. Models geared for high headspeed but lown aggressively at low headspeed
present the greatest challenge for the governor. The more optimally your model
is geared for your chosen headspeed, the better the governor will function.
Excessive governor gain worsens tail kick. Use as little gain as necessary for adequate headspeed control.
If the model yaws nose left with aggressive collective input, activate and adjust
the PIT→RUD F/F (feed forward) mixing. Increase in 2-5% increments. F/F
mixing should ADD pitch to rudder with added positive or negative collective
pitch assuming a CW main rotor direction.
76
1. Some Futaba transmitters contain auxiliary gain functions for aileron, elevator and yaw.
Please refer to your transmitter’s instruction manual. Assign the Gyro (RUD), Gyro (AIL)
and Gyro (ELE) channels within the transmitter. Within the CGY760R "S.BUS BASIC"
Rotor Head Gyro Gain "Gain A/E" – In the SBUS menu assigning "Gain A/E"
menu
to a channel will allow the Rotor head gain to be adjusted via the TX. If you are using
a 6CH or less TX, setting "Gain A/E" to "INH" will then default the gain to "BaseGain"
in the "FLT. TUNE" menu. Suggested setting and default is CH9. Tail Rotor Gain "Gain
RUD" – In the SBUS menu assigning "Gain RUD" to a free TX channel will allow for
the tail rotor gain to be adjusted via the TX. Suggested setting and default is CH5.
2. The gyro function within your transmitter should list all three gain channels. Adjustments can be made from within this function. The gyro function can usually be assigned to various switches or conditions to offer greater adjustability. Please refer to
your transmitter’s instruction manual for further details.
Setting the CGY760R gains by using endpoints or manual adjustments
WARNING
Verify that the gyro compensates in the correct direction for all three axes
before light. If the compensation direction is incorrect, the model will roll, lip,
or pirouette uncontrollably even before it leaves the ground.
1. If your transmitter does not support the remote gain adjustment it is still possible to use
spare channel on the transmitter to make the adjustments. Assign unused channel
(verify that these channels are not assigned or operated by a switch or dial) within the
transmitter. Set the "Gain A/E" channels in the "S.BUS.Basic" menu to the appropriate channel. Use the end point adjustment within your transmitter for these channels
to make the gain adjustments and the reverse function within the transmitter to set
the mode "AVCS/NOR". Conditions with the transmitter may also be used to achieve
different gains based upon light modes. Please refer to your transmitter’s instruction
manual for further details.
Manual gain adjustment
1. If your setup does not leave any channels free or if your transmitter does not support
auxiliary gain adjustment, then it is possible to adjust the gain manually within the
CGY760R. Set both the "Gain A/E" in the "SBUS. BASIC" menu to "INH". The gain
adjustments are now made by entering the "BaseGain" in the "FLT. TUNE" menu and
pressing the [ /+] or [ /-] key.

(7) Tail Resp: Tail response
(1) HeadHld A / HeadHld E: Head hold aileron / elevator
Take a match between helicopter tail response and gyro control. 1 is the
fastest response. Generally, if the tail response is slow or the servo's
speed is slow, setting the tail response setting late will increase the gyro
sensitivity and improve the control performance. Also, if the response setting is delayed, the power consumption of the servo will be reduced. However, if the response setting is too late, the operation can not keep up with
high-speed operation of the helicopter.
Heading hold aspect of the gyro control. If the helicopter is not holding
angle or cyclic control rates, increasing the heading hold gain will improve
holding the helicopter at a certain angle and improve the cyclic rate consistency. If this is set too high you could see an oscillation on that axis.
Lowering the heading hold below default would be used if the transmitter
gain is reduced and a consistent oscillation is still not ixed during light.

How quickly the RPM changes when increasing RPM
between two different RPM conditions and light modes.
A higher number slows the RPM change rate; a lower
value speeds up the RPM change rate.
Revolution fluctuation in the case of pirouettes
The governor detects the rpm by the revolution sensor mounted in the engine section. At the time of the pirouettes, the helicopter itself rotates, so
that its pirouettes speed is added (reduced) to the engine speed. Therefore, the main rotor speed of the ground will fluctuate. Since the CGY
760R has a gyro, it can accurately measure the pirouettes speed. The yaw
rate correction is realized by a combination of gyro function and governor
function.

Phase. Equ: Phase equalizer
This parameter optimizes swashplate phasing during pirouettes. Press the [ /+] or [
/-] key to turn the function on or off.
NOTE: This parameter needs rotor head RPM and direction of rotation to work correctly, so please set the rotor head RPM and direction in the governor menu. NOTE
that rotor head speed information must still be set into the CGY760R governor menu
even if using an electronic speed control (ESC) with an electric model.
Setting: ON / OFF
Feed Forward mixing is activated with this parameter. F/F mixing is a pitch to rudder mix applied outside of the gyro compensation’s control loop and before the gyro
itself can even sense undesired tail rotor movement. F/F mixing is handled within the
CGY760R. Do not attempt to use revolution or acceleration mixing within your transmitter as this will actually adjust the input signal to the gyro and cause drifting.
Setting: ACTIVE / OFF
ROT. Trak: Rotational tracking
This parameter tunes the rotational equalizer to the pirouette characteristics of the
model. When pirouetting the model at the desired rate, observe the model’s rotor
DISK (NOT the mechanics) and tune the ROT.Trak until the disk stays lat during the
pirouette. Find the best average setting for both left and right pirouettes.
Initial setting: OFF

PIT. Comp: Pitch Compensation
This parameter works to hold the nose and the angle that the helicopter is set at
regardless of collective pitch movements and direction changes. Press the [ /+] or [
/-] key to turn the function on or off.

Yaw. Smth: Yaw smoother
This parameter selects the rudder control feeling. When turned on, rudder control
becomes more exact. When turned off, rudder control authority increases. Select the
rudder control feeling to your taste.
