1/32 JR Mini 4WD Stier (MA Chassis)

The Hobby Hideaway Verdict: Inspired by the Power of the Bull! The Stier, named after the German word for "bull," is a striking addition to the Mini 4WD PRO Series. Its body design draws inspiration from modern two-seater hypercars, featuring a distinctive U-shaped front section that sweeps back from its tip to the front fenders to mimic a bull's horns. At Hobby Hideaway, we love this kit for its aggressive aesthetic and the fact that it sits on the highly efficient MA chassis, making it a fantastic choice for racers who want a car that looks as fast as it performs.

The MA Chassis: Midship Aero Efficiency The MA (Midship Aero) Chassis is the heart of this build, designed with a heavy focus on balance and aerodynamic flow. By placing the double-shaft motor directly in the center, the MA provides a symmetrical layout that ensures equal weight distribution and efficient power transfer to all four wheels. It is a one-piece, rigid platform that is incredibly easy to assemble and maintain, making it a go-to for both newcomers and veteran racers who value a stable, reliable chassis during intense sessions at our track.

Sleek Design Meets Pro Performance The Stier isn't just about looks; it is a purpose-built racer. The silver ABS plastic body features separate rear fender parts for added detail, and the included metallic stickers give it a professional, factory-finished appearance. Paired with a high-speed 3.5:1 gear ratio and low-profile tires, this machine is designed to stay low and maintain high velocity through every corner of the circuit.

Hobby Hideaway Pro Tip: Before moving up to faster motors, the most effective way to improve the Stier's performance is to reduce friction. Replacing the standard plastic bushings with Hex Hole Ball Bearings will allow your axles to spin more freely, giving you a noticeable boost in both speed and battery life. This is the natural first step for any MA build, as it strengthens your foundation without pushing you into a higher speed class before you're ready to handle the technical jumps!
