I dropped my Zipzap 1 and a half feet off the floor. It was a very minor fall, so I didn't have the slightest hint of damage. Well, my car wouldn't steer left anymore. I checked the wiring and everything seemed fine but it still didn't work. I resoldered on all the steering wires, but that didn't do anything. I wa starting to suspect the pcb board was having problems. I switched the left and right, and now it turns left but no right. That proved that it was the pcb that was having problems. What's wrong and what can I do to fix this?
