Make Some Noise at the Track! This Mini 4WD model assembly kit creates the Rowdy Bull, a brand new model with a muscular appearance bound to excite! It features a long, bulging bonnet with integrated air intake and a powerful-looking wide-fendered tail section. Dedicated marking stickers are included in the kit to decorate the body, as are silver color metal-plated A-spoke wheels, and low-profile tires. 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 low-friction front skid bar and roller (4 included) parts, while rear rollers are 8mm thick for superb stability. The chassis underside allows easy access to the motor and quick setup changes. Includes 3.5:1 gears and a motor.
