Adjustment at the device
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 trans-
mitter 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.
110.2 Cyclic adjustment
Dial 1: Cyclic gain
The swash gyro gain (cyclic gain) can be set by dial 1 from 50% up to 150%. The factory
setting is horizontal which corresponds to 100% swashplate gain. Turn dial 1 clockwise
to increase the gain and counter clockwise to decrease. For your first flights we suggest
not changing this setting. However, when using very small helicopters (such as 250 or 450
size), reduce the cyclic gain by 3 marks (=75% gain) as with such small helicopters the
control loop tends to overcompensate more easily.
