Using the CGY750 with a electric helicopter

󾾝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.

Low battery

󾾝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.

SETTING MENUS

󾾝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-

tings menus to ease set up.

￸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.
