This morning i was driving on our local track and suddenly my car starts to stutter under acceleration. (11 Lipo Pack's for so Far)
After a check of the settings with hotwire a went to the Track again and hit the Throttle. I heared my motor turning but my Car wasn't moving at all. I think the magnets has come loose from the Rotor
My magnets let go as well. Called last Monday, got the new rotor Friday as promised and so far so good. Give them a call or e-mail your info and they will replace it. Very friendly service.
