Tail gyro
Gyro gain and operation mode
The tail gyro gain is adjusted by one of the transmitter‘s auxiliary channels. The more servo throw this channel produces, the higher the tail gyro gain will be. Additionally, the direction of servo throw determines whether the gyro operates in Normal-Rate mode or in HeadingLock mode.
While adjusting the gain or after initialization sequence was finished, the current amount of gain is displayed by one of the menu LEDs for about 10 seconds: When the gain channel is centered, this will correspond to 0% gain indicated by LED A. The maximum adjustable tail gain is 100% and will correspond to LED N.
The color of the Status-LED indicates the selected mode: Purple indicates Normal-Rate mode and blue indicates HeadingLock mode.

Please note that the actual percentage and sign of servo throw in the transmitter will depend on its brand and/or type! For the first flight we suggest to start with medium gain not higher than LED G (LED D for 450 size helicopters and smaller) in HeadingLock mode (Status LED blue).
- Operation without using the auxiliary channel for tail gyro gain is not possible!
- When gain is close to point A (0% gain) the rudder servo will not perform full servo travel as the gyro is switched off. Do not attempt to fly in this condition!
Dial 3: Tail gyro response
Factory setting of the dial 3 is horizontal which provides a good setup in most cases. Turn dial 3 clockwise to increase the tail gyro response. Turning dial 3 counter clockwise will decrease it. Increasing the gyro response will cause a harder stop and quicker response to rudder stick inputs.
