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.
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

three times between Normal Mode and AVCS Mode (Normal

that the new center position has been memorized.
When operating the gyro in AVCS Mode, all compensation and revo-
lution mixing must be disabled and any tail rotor or swash offsets for
light modes must be disabled.
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.

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 func-
tion 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.

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.
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 neces-
sary to prevent an unexpected lift off as the governor activates and the
head speed increases to the desired RPM.

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 gover-
nor operation. Due to the high level of vibration and centrifugal forces
the magnet may come loose or the sensor alignment may change. Ev-
