Gyro Direction
Normal Reverse
The gyro has two move directions, Normal and Reverse. Rotate the helicopter at least 90 degrees
counter-clockwise, in an attempt to oppose the rotation and maintain the helicopter heading the gyro
should have now moved the tail blades in the same manner as if right rudder was applied, the direction
of the gyro is correct. If its not, please change the setting.
The step above is critical. If the gyro direction is wrong, the helicopter may yaw at high speed and
cause an extremely dangerous situation when taking off!
Step 2: Adjust High Servo Endpoint
When set gyro direction ok, toggling the gain switch to Rate and AVCS one time, you are in Adjust
High Servo Endpoint setting. Using the Rudder stick adjust the servo position until you achieve
maximum tail rotor pitch without binding on the mechanical limits. When satisfied, toggle the gain
switch to Rate and AVCS one time to next setting.
