Description
The Rowdy Bull is a Mini 4WD body with a muscular, wide-fendered stance: a long bulging bonnet with an integrated air intake up front and a broad tail section at the rear. Silver metal-plated A-spoke wheels and low-profile tires are fitted, and dedicated marking stickers are included to finish the body. It runs on the FM-A (Aerodynamic Front Motor) chassis, a front-motor layout with its weight biased forward, positioned by Tamiya as suited to a wide range of course layouts including sections with elevation changes. The chassis carries a low-friction front skid bar with four rollers and 8mm-thick rear rollers for stability, and its underside is designed for quick access to the motor during setup changes.
