Here is a shot of the gear box on my 4x. the other side is the same.
I spent the last few eve's trying to figure out the transmitter and how to get the buttons to properly steer the car. Thanx to QFM for posting the wiring diagram! Not an easy mod because it requires new circiuts added to the PCB. It is a bit more dificult than I expected since as it starts you are controlling forward and reverse on each motor with each control. That means the forward/reverse control just turns the car by driving one set of wheels, and the same for the steering. You have to use forward and right turn to go straight etc. The mixing of the controls inside the TX was the only good way to correct this. And it can be done. The car now drives normally, all controlls as they should be. (Yeah!)
