My car wont go, but it will steer, what is the problem?
 

I just recently found my xmod in a closet, and I decided to put it back to stock parts, I used to have the 6 cell mod, but I decided to take it out, when I put batteries in my car and started it up again, it could steer, but the motor wont go or make any noise. I tried two other motors and neither worked. I also tried a second remote to see if that was the problem. I think I may have blown my FET, has this happened to anyone, or does anyone know the cause/solution to this? Thanks!
