Well, removing the opti drive did me absolutely no good. I turned the revo back on and noticed that im not losing control of the servo as i thought, but its neutral position keeps moving back and forth. For a few seconds it will be centered in a good neutral position then it will move backwards and apply a little brakes then move forward and push against the throttle linkage on its own. It still moves when I use the trigger but isnt doing me any good changing positions on its own. Anyone had this problem?
