Servo Neutral - KDS Flymentor 3D User Manual

3 .4 .2 Servo neutral

Servo neutral should be set after reverse is set. You should adjust neutral to make the rocker at
suitable position. Normally, the position means angle between rocker and pole is 90° , like
diagram 3.4.3.
Before adjusting neutral, you should make the neutral of mechanism on approximate position,
then use software for precise adjusting.
You should aware that the neutral is mixed neutral, for example, when we adjust the aileron
neutral of CCPM120°, servo1 and servo2 will wiggle at the same time ( opposite direction) .
So you should adjust neutrals by following steps, suppose your swashplate is CCPM1 20°:
1） Adjust aileron neutral, make servo1 and servo2 same height. Don't care if the height is
enough.
2） Adjust elevator neutral, make servo1,servo2 and servo3 same height (swashplate was
horizontal).
3）Adjust pitch neutral, make the swashplate at proper height.
Adjusting of tail servo and servo4 are independent, you should adjust servo4 after aileron,
elevator and pitch.
* Attention: to avoid injury, please unmount main rotor and shut off power!
