I think I am going to replace the whole belt and pulleys, but I want to see does anyone hear experienced the same and know exactly where is the problem...?
I bet is mostly the rear belt....but really hard to tell. I have tried tighten the belt tensioner or loosen it...the problem still exist.
I had the same thing happen to mine (E4-RS not 09) and had to keep tightening the belts until they didnt skip.
What I did was have someone hold the front wheels and then try to turn the back wheels and see how hard it was to make the belt skip. They should be pretty hard to make skip if they aren't tighten the belts until it is hard to make them skip. (be careful not to try too hard you can damage the car)
another thing is do you have an aluminum rear upper deck mount?
Mine is plastic and can flex enough to make the belt skip.
Also wolf hobbies makes an aluminum rear chassis brace to help with flex.
Hope this helps,
