I thought I would do a little cleaning of my sport so I decided to take it apart and clean the body and the some of the parts. When I was putting it back together I tested the remote survos to make sure they worked which they did. So I put it back together. When I got everything back together I tried to turn my car back on and nothing worked. I can get it started, but the remote portion of my car will not turn on. The four batteries you use for the car heat up when I turn it on. Can anyone help and let me know if I burnt something up?
