to bearing.
With the tail pitch slider in this position, the
helicopter will turn clockwise.
Set the limit of the tail servo to 16.3mm from slider
to bearing.
With the tail pitch slider in this position, the

When you turn the nose to the left (counter clockwise), the tail pitch slider must go towards the tail rotor hub
and away from the tail case.
When you turn the nose to the right (clockwise), the tail pitch slider must move towards the tail case and the
bearing.
