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.

The Mini 4WD FMA chassis puts the motor up front, which changes braking and jump attitude completely. Tuning around that forward weight bias.
We counted every non-kit SKU in our own 289-item Tamiya catalogue by named chassis. MS, AR and Super XX lead, but two-thirds of parts name no chassis at all.
