My slash 2wd was acting fine when i stopped running it. It was only after I brought it inside with me. I don't know if I cooked my speed control, but if i did, it happened when it wasn't outside. It spun its wheels like normal. Nothing broke as far as i can tell. My ez set button was sticking though. Could it have done something that way? I put the Velineon 3500 motor and vxl-3s speed control and TQi transmitter on it. This is the first problem with running that I've had, besides plastic stuff that I could see was broken.
