The car is a 1:28 model as you get them in the shops. The only modification is a plate to carry camera and lights. On the arcade side there is a basic arduino microcontroller, the remote is controlled by a different controller, both communicate via a serial cable. One part of the job is to help out when the car crashes. Arcade and track are setup in seperate rooms. The installation is highly modular and can be set up in about three hours.
