This will make the nose of the helicopter rotate to the right.


Next disconnect the rudder link from the servo. Remember that a few hundred rpm drop on the head is several hundred rpm drop on the tail.

One direction will set the gain value for heading hold and the other will be for standard rate. Confirm that no sub-trim or ATV is present in the transmitter in any flight condition on the rudder channel. Once the center of the ball link matches with the center of the ball and you have the 4. Set the DIP switch on the gyro for digital servo, assuming the or is installed.

The RPM’s should be to for 3D flight. Tail wags only right after a pirouette, or anytime I move the tail then stop. Do not disturb the rudder.
