Also if you are using personal transponders, remember that they have to be mounted horizontally.

Another thing, I had the wire from one of my personals get caught underneath the chassis, where it rubbed through and shorted out. The personal was ok, but since it operates out of the battery slot on the receiver, it fried my Noval XXL instantly and the car took off into a wall, where it promptly fried the motor as well. It was an expensive lesson.
