Gyro Gain Trimmer Pot Description and Adjustment
The “gain” trimmer pot adjusts the gain setting value of the piezo gyro used to aid in keeping the tail of the
helicopter straight/on heading during flight.
• The gain value is set too high if the tail of the helicopter twitches/bounces quickly from side to side when in
hover. If this is case for your model, reduce the gyro gain in small increments until the tail of the helicopter no
longer twitches/bounces from side to side in hover.
Turn the gyro gain trimmer pot counterclockwise (-) to decrease gyro gain.
• The gain value is set too low when the tail of the helicopter feels “loose” during flight, requiring constant left and
right rudder inputs to maintain heading when in hover. If this is the case for your model, increase the gyro gain in
small increments until few, if any, left and right rudder inputs are required to maintain heading.
Turn the gyro gain trimmer pot clockwise (+) to increase gyro gain.
Note: When adjusting the gyro gain trimmer pot, the changes will take effect without the need to power
down and re-arm the 4-in-1 unit. However, please exercise extreme caution when adjusting the gyro
gain trimmer pot with the model armed to prevent personal injury or damage to the model.
