The CGY750 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 CGY750 is now ready for flight.

WARNING
Newer high end servos and other radio equipment
are capable of placing large demands on the power
systems in use today. When using a regulator you
must ensure that the regulator is capable of supply-
ing 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 han-
dling high current draws.

Even though the CGY750 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 be-
low and address all issues before installing and fly-
ing the CGY750.

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 pow-
erful and capable of delivering the power instantly, causing injury
to yourself, others, or the surroundings.

WARNING
The [Low Batt] warning is displayed if the receiver battery voltage falls
below the [BAT/FS] voltage set within the CGY750 Governor Expert menu.
If this condition lasts for more than one second, then the Battery Fail Safe
function activates, and the throttle servo is brought back to idle position.
This is done to warn you that the battery voltage is dangerously low and that
you must land immediately.

WARNING
Always exit the Setting Menu and return to the home screen before fly-
ing your model. The gyro operation is disabled within several of the set-

Always check the operation of the CGY750, verify that the controls are
operating the correct direction and ensure the gyros are correcting in the
proper direction for all axes prior to attempting to fly the model.
