From the Tamiya: 

    This assembly kit creates a Black Special version of the Manta Ray Mk.II Mini 4WD racer, with the body molded in tinted Smoke color. Stickers are included in the kit to decorate the body with predominantly black and blue markings. The 3-piece MS chassis utilizes glass fiber reinforced ABS N-02 and T-01 units. It comes with black large diameter wheels and narrow blue tires.

The direct drive, double-shaft motor MS Chassis features a 3-piece setup split into nose, center and tail units for easy attachment and detachment. Its 80mm wheelbase provides an advantage through corners.
