Kyosho Mad Wagon, center differential specification, has been run about 10 times. The body and tires are new. Also, an original painted body is included. Please understand that it is amateur quality. This is a ready set including the main unit, transmitter, instruction manual, and original box. It has been customized with a center differential instead of the normal slipper clutch, so it will run at full speed without slipping when using a 3-cell battery (removed parts are also included). Since it is used, please refrain from purchasing if you are nervous or concerned. Batteries can also be included. Hobby radio control #G6-01
