This is an ultra rare CEN micro nitro slider or roller truck. Will need your choice of engine and electronics, wheels/tires and body. All this tech crammed into such a small footprint, I was intrigued! I planned to convert it to electric and buy parts for the mg10 so I coukd swap between 10th and 16th scale, but it's just been sitting around collecting dust. It was only ran a few times. The drivetrain is still tight and has not been broken in yet. It's almost new! As with all hobby-related items it is being sold as-is.
