• Vibration will affect the GY701’s overall perfor-
mance. All rotating components on the helicop-
ter should be balanced to minimize vibrations in
ight. Ensure that your motor is running smooth
and all vibrations have been addressed before
installing and test flying the GY701.
WARNING
Newer high end servos and other radio
equipment are capable of placing large de-
mands on the power systems in use today.
When using a regulator you must ensure that
the regulator is capable of delivering the cur-
rent demands of the equipment you have se-
lected. In addition to this make sure the wiring
and switch you have selected are capable of
handling high current draws.
Even though the GY701 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
test flying the GY701.
• The GY701 must be used with a rigid tail rotor
drive system. Any modern torque tube or belt
drive system should be adequate. Do not at-
tempt to fly the GY701 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 GY701.
If any binding is present it must be fixed before
the helicopter can be flown. Binding in the tail ro-
tor control linkage will decrease the performance
of the GY701 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, without friction or binding.
