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 immedi-
ately.
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. Bind-
ing 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 cor-
rectly and without friction or binding.
• Vibration will affect the CGY’s overall performance. All rotating compo-
nents 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.
