: Prohibited
: Mandatory
WARNING
Failure to follow these safety precautions may result in severe injury to
yourself and others.
· Read through the entire manual before operating this product.
USAGE PRECAUTION:
- When using FASSTest 12 CH mode, analog servo can not be used for 1-6 CH output for conventional system.
- The FASSTest system is not compatible with the conventional FASST system.
CAUTION
Do not mount GPB-1 (Gyro Program Box) on the helicopter.
- It will be damaged by vibration.
ANTENNA INSTALLATION PRECAUTION:
WARNING
Be sure that the two antennas are placed at
90 degrees to each other.
90°
*The CGY760R has two antennas. In order to maximize sig-
nal reception and promote safe modeling Futaba has ad-
opted a diversity antenna system. This allows the receiver
to obtain RF signals on both antennas and fly problem-free.
11
Do not cut or bundle the receiver antenna wire.
Do not bend the coaxial cable. It causes damage.
To prevent damage to the antenna, please exercise caution. Do not bend at the
base of the antenna. Also, ensure that the unit is not subjected to impact
damage.
Keep the antenna as far away from the motor, ESC and other noise sources as
you possibly can.
CARBON FUSELAGE PRECAUTION:
WARNING
You must leave 30 mm at the tip of the antenna fully exposed. The exposed antenna should be secured so that it can not move around or back inside of your aircraft.
CONNECTOR INSERTION PRECAUTION:
%”/(&3
WARNING
Do not connect the connector by mistake as shown on the right.
BEFORE EACH FLIGHT:
Do not connect either a switch or battery in this manner.
WARNING
Keep away from conductive materials to avoid short circuits.
If it does not operate properly during operation test before use or use, stop using it.
Always check the transmitter and receiver battery voltage to ensure they have enough remaining capacity to complete the flight.
Confirm that the CGY760R/CGY755 is operating in the correct mode.
ABOUT BATTERIES: WARNING
Newer high-end servos and other radio equipment are capable of placing large
demands on the power systems in use today. When us-
12
ing a regulator you must ensure that the regulator is capable of supplying the
current demands of the equipment you have selected. In addition to this make
sure the wiring and switch you have selected are capable of handling high
current draws.
The servo current draw can be up to 50% higher on a flybarless helicopter. Always ensure your receiver battery is fully charged before each flight.
ABOUT CONNECTOR:
Insert the connector such as sensor, servo, connection cable, battery etc.,
surely.
If it is not securely inserted all the way in, it may come off due to vibration during flight and there is a danger of falling.
ABOUT WIRING:
Please secure the wiring so that it does not rub against the helicopter frame
or other such items that could cause wear. If it does so, we suggest covering
these ares with fuel tubing (or similar) to prevent damage.
ABOUT VIBRATION ISOLATION AND WATERPROOFING:
The CGY760R/CGY755 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 flight. Also, if there is a risk of
the gyro getting wet, place it in a plastic bag and take waterproof measures.
ON FLIGHT PRECAUTION:
Always exit programming mode before attempting to fly the model.
Gyro operating precautions: Gyro
The CGY760R/CGY755 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/CGY755 is
now ready for flight.
13
Verify that the gyros are operating and compensating in the correct direction
before each flight. If the compensation direction is incorrect on any axis the
model will become uncontrollable after takeoff.
The servo type parameters within the CGY760R/CGY755 must match the type of
servo you are using. Incorrect setting may damage the CGY760R/CGY755 or the
servos, possibly resulting in a loss of control during flight.
Always allow the gyro to adjust to the surrounding environmental temperature
before flight. A large temperature change during use will cause drift and
other operational issues.
If you are switching between Normal Mode and AVCS Mode in flight, 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 flip 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 flight modes must be
disabled.
Do not drop the CGY760R/CGY755 onto a hard surface or subject the
CGY760R/CGY755 sensor to a strong shock as this may damage the sensor.
Verify that the gyro is operating in the desired mode.
When the CGY760R/CGY755 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 flight 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,
14
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.
WARNING
Never turn off the CGY760R/CGY755 while the GX (gyro) LED is blinking green at
high speed (about 5/sec).
*If the power is turned off while high-speed blinking, a data error will occur and all data will be initialized. It is very dangerous to fly as it is.
Governor operating precautions: Governor
When the throttle servo is connected to the CGY760R/CGY755, the battery fail-
safe function within the CGY760R/CGY755 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 flight or starting the engine, always ensure the throttle
remains below the governor activation point and do not select any flight 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 -1 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.
15
Be sure to set the autorotation condition 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. Every 10th flight 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/CGY755 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 flying the CGY.
· The CGY 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 fly the CGY
using a wire driven tail rotor system.
· 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 CGY.
Binding in the tail rotor control linkage will decrease the performance of the
CGY 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.
· Vibration will affect the CGY’s overall performance. All rotating components
on the helicopter should be balanced to minimize vibrations in flight. Ensure
that your engine or electric motor is running smoothly and that all vibrations
have been addressed before installing and test flying the CGY.

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 CGY gyro sensor is the most vibration resistant gyro sensor available,
eliminating vibrations will always improve performance. The CGY gyro sensor
performs best when the sensor is mounted rigidly to the airframe. 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 flight 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 flight
performance.
Using The CGY With An Electric Model
DANGER
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.

Link Method With Transmitter (FASSTest / T-FHSS)
For CGY760R
1. Connect the CGY760R and GPB-1 and set the same mode set in as the
transmitter linking the CGY760R communication mode on the “Receiver” screen.
(See page 36)
2. Keep the transmitter and receiver close to each other and turn on the
receiver with the transmitter in the link mode.
3. After powering on the receiver, please allow for approximately two seconds
for the binding/linking to occur.
4. The LED indication on the receiver will change from the red blinking light
to a solid green. This indicates that the linking is successful. This usually
occurs in approximately one second. Refer to the transmitters instruction
manual for complete details on how to place the transmitter into the linking
mode. If there are many T-FHSS or FASSTest systems in use when attempting to
link the transmitter to the receiver, it might require more time to do so.
Additionally, if another modeler in close proximity is attempting to link
their units simultaneously, it could also cause difficulties as the receiver
might inadvertently link to the other transmitter. Always confirm that the
receiver responds to the input from the desired transmitter. * If the System
Type of the transmitter is changed, the receiver will need to be relinked to
the transmitter. For example, if the transmitter is changed from T-FHSS to
FASSTest, it will be necessary to perform the linking procedure once again.
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 first, followed by the
receiver.
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
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 test-
ing” 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.
Sensor Magnet
&RROLQJ)DQ0RGL¿FDWLRQ
1. Drill a hole in the fan at the magnet mounting position. Make the hole about 4.1 mm in diameter and 1.5 to 1.7 mm 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.
Magnet
Cement the magnet to the cooling fan so that the magnet is level with this side of the cooling fan.
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).
Sensor Mounting
The sensor mounting method depends on the model and engine. 1. Temporary the
sensor to the sensor mount. 2. Drill a hole in the fan cover at the part
corresponding to the sensor so that the dis-
tance between the sensor and magnet can be made 1 to 2 mm.
25
3. Tighten the sensor stay together with the engine mounting flange.
(Temporary assembly)
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.
5. Install the sensor to the sensor stay using the accessory screws and
washers.
6. Tighten the sensor stay together with the engine using the engine mount
screw.
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”.
Sensor Magnet
Center of sensor is offset.
Sensor case
1 – 2 mm
2.2 mm
3.7 mm 3.7 mm
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 2 mm. 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.

Throttle Servo Linkage Precautions
· To effectively use the governor, observe the following precautions when
connecting the servo linkage. · 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%. · Fly with the governor turned OFF and
adjust the needle so that the engine smoothly reacts to movement of the
transmitter stick. · 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.

(7) ELE. Comp: Elevator pre compensation
A helicopter that has a head that rotates clockwise, will exhibit a tendency
whereby the nose will be pulled towards the disk with positive blade pitch.
Conversely, the helicopter will push the nose away from the rotor disk during
negative pitch inputs. In an instance of a slower servo set-up or larger
(heavier) rotor blades, a small amount of elevator pre compensation may be
needed to keep the nose of the helicopter flat at all times during collective
pitch changes. In most cases with helicopter high-speed servos and standard 3D
rotor blades, this function is not needed. If you do notice a slight tendency
for the nose to try to rise or fall with collective input, increasing “ELE
Comp” will reduce this behavior.
Setting ranges: 0 ~100% Initial value: 0%

(8) HP. Auth.: High pitch authority
When a rotor blades angle of attack is increased, the rotor blade becomes less
reactive, in turn the helicopter might not feel as reactive at high pitch
angles. If you want to increase the reaction of the cyclic during loaded and
high pitch maneuvers, “HP. Auth” will increase control authority and can be
used to make the helicopter feel more linear under loading. Some helicopters
with direct link CCPM may use this to increase stability at high collective
pitch flying as well. If a helicopter feels good for normal flying, but not
the same during loaded situations, “HP. Auth” can be used to make it feel more
linear. If “HP. Auth” is set very high, the helicopter will feel more
aggressive at high pitch than around neutral.
Setting ranges: 0 ~100% Initial value: HP. Auth = 0%

WARNING
The servo type parameter within the CGY must match the type of servo you are
using. Incorrect settings may damage the CGY or the servo. An incorrect
setting may also result in a loss of control during flight.
(1) Servo Type
Select the appropriate setting for the tail rotor servo. Move the cursor to
“Servo Type” by pressing the [ /+] or [ /-] key and press the [Enter] key to
enter the setting mode. Then select the servo types: DG1520, DG760 or Analog
with the [ /+] or [ /-] key. When “EXECUTE: Enter (1 sec)” is displayed, press
the [Enter] key for about 1 second to changes the selected type and exits the
setting mode.
Setting: Analog / DG:1520 / DG760 Initial setting: DG:1520 DG 1520: BLS254,
BLS257, S9254, S9257 DG 760: BLS276SV, BLS251SB, BLS251, S9256, S9251
(2) Gyro. Dir: Gyro direction
This parameter controls which direction the CGY (yaw axis) will compensate
when the helicopter rotates. Hold the tail rotor linkage over the linkage ball
on the servo, pick the helicopter up by the main shaft and rotate the
mechanics counter-clockwise. The CGY should compensate by adding clockwise
rotation pitch to the tail rotor blades. If the CGY compensates by adding
counter-clockwise rotation pitch to the tail rotor blades, then it will be
necessary to reverse the Compensation Direction setting by pressing the [ /+]
or [ /-] key.
Setting value: Normal / Reverse Initial value: Normal
58
(3) Srv. Limit: Limit setting
When the CGY is in the “Srv.Limit” parameter mode, the gyro will no longer
operate and the tail servo will always center when the tail rotor stick is
released. Always exit the setup functions before attempting to fly the model.
Before each flight, always ensure that the gyros are operating and
compensating in the correct direction. The Servo Limit parameter within the
CGY 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 CGY 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. Ensure that the pitch slider does not bind at the
maximum movement inputs.
WARNING
When using the CGY for the first time, or when making mechanical changes
involving throw, you must check and set the servo limits again to prevent
binding.

WARNING
Always level the swash plate using the cyclic stick before applying throttle
and spooling up the main rotor blades. 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 firmly 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.
When the CGY is used with an ESC or BEC and a power switch is not used, there is a possibility of an intermittent connection when connecting the flight battery. This may cause the CGY 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.

TRANSMITTER ROTOR HEAD GYRO GAIN SET-UP
Transmitter Set-up for adjusting cyclic gains via the transmitter.
Using the Remote Gain Functions (roll, pitch and yaw)
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 (Rotor Head replaces AIL/ELE) channels within the
transmitter. Within the CGY “S.BUS BASIC” menu Rotor Head Gyro Gain In the
SBUS menu assigning “Rotor Head gain” to a channel will allow the Rotor head
gain to be adjusted via the transmitter. If you are using a 5 or 6CH
transmitter, setting “Rotor Head gain” 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
transmitter channel will allow for the tail rotor gain to be adjusted via the
transmitter. 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.
WARNING
Verify that the gyro compensates in the correct direction for all three axes
before flight. If the compensation direction is incorrect, the model will
roll, flip, or pirouette uncontrollably even before it leaves the ground.
Setting the CGY gains by using endpoints or manual adjustments
1. If your transmitter does not support the remote gain adjustment it is
still possible to use a spare channel on the transmitter to make the
adjustments. Assign unused channels (verify that these channels are not
assigned or operated by a switch or dial) within the transmitter. Set the
“Rotor Head gain” 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 flight 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 CGY. Set both the “Rotor Head gain” 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.

(2) EXP. AVCS / EXP. NORM: Rudder exponential
This parameter sets the feel of the tail rotor control around center. When set
to [0] the control curve is linear. Using a [+] value the tail rotor will be
more sensitive around neutral conversely, using a [-] value will soften the
feeling around neutral. The RUD EXP parameter in your transmitter can also be
used to tune the tail rotor to a desired feeling.
Setting ranges: -100 ~0 ~+100% Initial value: AVCS = -20%, NORM = -20% Sports

(7) Tail Resp: Tail response
The goal is to match the response between the helicopter tail response and the
gyro control. This feature is utilized to do so. 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 cannot keep up with high-speed operation of the
helicopter.
Setting ranges: 1 ~5 Initial value: 1

(1) HeadHld A / HeadHld E: Head hold aileron / elevator
This features is used to adjust the 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 fixed during flight.

Revolution fluctuation in the case of pirouettes The governor detects the rpm
via the revolution sensor mounted in the engine section. During a pirouettes,
the helicopter itself rotates, so that its pirouettes speed is added (reduced)
to the engine speed. Therefore, the main rotor speed will fluctuate
accordingly. Since the CGY has a gyro, it can accurately measure the pirouette
speed. The yaw rate correction is thus determined by a combination of gyro
function and governor function.
