This is a neat little (1/28) motorized kit, originally made by Nitto (kit nr. 666, also released as kit nr. 14058). The kit consists of a one-piece body, a detailed interior and a fairly simple floorpan. The front wheels steer, the electric motor is hidden below the fuel cell in the rear of the car and a single AA-size battery is hidden in the nose. An accurate set of decals is included for a japanese factory race car.
