Master CP Pitch Servo arm drifts up

[topcat1]

Heli was in a crash and I rebuilt it again totally. All servo arms are at 90 degrees at mid stick, I leveled the swash so it has equal movement up and down. And now that I am working on getting the blade pitch correct (0 degrees at mid stick) this weird malfunction comes up. It just started doing it, it was fine last week when I was leveling the swash but now every time I move the throttle stick up the other 2 servos move together to keep the swash level but this pitch servo starts up and wants to drift way up and has the swash banked to the left hard. Do you think this servo could have gotten damage in the crash? It sounds fine, they were all were working fine after the crash, they are metal gear servos.

Two things to check: first make sure your servos are plugged into the correct port on the RX. Second, make sure the servo is not stripped. I have stripped the metal gear servos. When in doubt, replace the servo. That is better than having to rebuild it again or worse. I hope this helps.

I agree with you I came to that conclusion also, even though the servo does not sound stripped there is a good chance that it is bad I will replace it.
Thanks.
