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 delivering 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 handling high current draws.
• Even though the GY520 is a high performance gyro 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 fl ying
the GY520.
• The GY520 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 GY520 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 GY520. If any binding is present it
must be fi xed before the helicopter can be fl own. Binding in
the tail rotor control linkage will decrease the performance of
the GY520 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.
• Vibration will affect the gyro’s overall performance. All
rotating components on the helicopter should be balanced
to minimize vibrations in flight. Ensure that your motor is
running smooth and all vibrations have been addressed
before installing and test fl ying the GY520.
