I have built a four wheel remote control car that took two days to build. I used the button box from the two wheel remote control car. There are three buttons, the first button makes the four wheelremote control car go foward. The second button makes the remote control car go backward. The third button makes the remote control car go left. I raised the four wheel car by putting the four motors under the RCX brick. Before the wheels were in the front now they are under the four wheel remote control car. I added two wheels to the remote control car to make it a four wheel remote control car. It is a lot faster than the old car by 12 seconds and the turning is a lot worse because the two new wheels are in the way. The four wheel remote control car goes a lot straighter than the old car.
