i did find one problem the heatsink that was on the motor was rubbing against the shaft.
if you look at the picture and you see the white box, thats where the heatsink i had on the motor slid back and rubbed against that outdrive or whatever that part is called and did eat some of it up. i found this problem cause when i took the body off.

i have not tryed to run the car yet since its raining out but hopefully that was the problem.
