crazy servo
 

I had a ace 1015 on throttle, it will center perfectly but as soon as I apply brakes the servo will center at WOT :confused: So i replaced the servo with a 7955 and still the same...has any one else had similar issues?

When you apply full throttle, it will return to center but when you apply full brake, it returns to full throttle position?

If that is the case, is the servo horn stripped and shifting on the output gear?

I have checked the servo arm its not stripped. When I switched servos I switch the arm also and still the same

Did you center the servo & re-adjust trims & other settings on radio back to zero before fitting servo arm.
Also, if you apply the brakes & the servo moves to the WOT position, its moving in reverse, what happens when you apply the throttle, does the servo move to full brake position.?
