Hi. Currently I own the Initial D Kit with an added 3.0 motor. Yesterday, I accidently dropped the car. It started to run slower than usual. Now, the gears would spin but the wheels wouldn't. It'll only move about an inch then the wheels would stop. I've read online to try cycling. I've done that but no luck. I also heard about "straightening the wires". I was confused about that one. What should I do? I don't wanna go out and order another one. Thanks.
