Hello, I have some issues with my RC car that I bought from Walmart. I was playing with it, and I crashed it into a surface and got stuck. It was also being pressured downward. When I tried accelerating it, it wouldn't move. The steering works, and everything else works except the accelerator. I opened the car to see what had happened, and I didn't see any malfunctions or improper wire placement. I removed the geras from the gearbox, ALL I SAW was that the motor wasn't spinning even though everything was in good shape. Can you help me find out why?
