This assembly kit creates a Black Special version of the Copperfang (Item 18715), a car which was developed from an entry into the Tamiya 2018 Mini 4WD Design Contest. The kit employs a unique muscular body with fang-like front fenders that was inspired by the copperhead snake. It is based upon the front motor FM-A chassis, which offers steady performance on a range of track layouts. FM-A: Aerodynamic Front Motor Chassis The FM-A chassis is a front motor unit with advanced aerodynamic themes that - thanks to its center of gravity toward the front - is at home on a whole variety of track types including those with frequent elevation changes. It comes equipped with a low-friction front skid bar, while the chassis underside allows easy access to the motor and quick setup changes. Aircraft-inspired aero side stays allow attachment of a range of Grade-Up parts. The chassis is molded in durable ABS, with low friction A parts such as under panel, all in matching black. Smoke color metal-plated A-spoke wheels are combined with low-profile tires, and the model includes 3.5:1 gears. • Mini 4WD model assembly kit.
