I just purchased and installed a new HS-82mg into my merv and everything went fairly smooth except now when I turn on the radio and turn the wheels left and right it wont always center itself. It kinda stalls half way, makes some noise and wiggles a bit. It is like the servo is having a seizure or something. I read through the manual and tried to reprogram the radio\esc but nothing has seemed to help so far. Any ideas or suggestions on how to fix this or what I might have done wrong would be greatly appreciated. Oh, I am using the stock 2.4ghz traxxas radio. Thanks!
