I have a Hitec servo HS-925MG that a got in July & now it won't hold the
center postion. It was ok at the start but now it pulls to either the left or right. I tried it reseting my radio gear & adjusting the servo trim & centers but nothing works. Yet my other servo a Futaba 9402 servo works great, so I don't think it's my radio (A Super 3PJ with a Futaba FP-R113iP or a Novak XXL recv.)
I tried it in both my RS4 Nitro car & my TC3 with the same problem in both.
I even had my friend try it in is 1/8 scale gas car with no luck. I open it up to check the gear (as my lhs suggested) but their fine. Is there anything you can recommend to try & fix it or should I just send it in for warranty.

Thanks Mach3
