I have a HPI roto start on my mammoth, but them gears in the roto start are like slipping. I pulled it apart and the gears look fine. But when i push them gears around they like go out of place a little and i think thats the problem. But how come im all suddenly having this problem? And by the way its not the one way bearing, cause i know alot of people will suggest that it might be the problem.

Thx
