A Cute Speedster
This is a Mini 4WD racer assembly kit which creates the Panda Racer GT, an exciting kit that uses the stylish Astralster GT car-style body molded in clear green with a simply adorable pre-assembled and painted Panda Racer figure for the driver's seat. Metallic stickers were designed just for this model. The midship motor MA chassis is molded in a matching fluorescent green, with A parts like the rollers and rear skid bar in white. Fluorescent green 3-spoke wheels and yellow tires round off the look, and ensure that no-one will fail to notice your Panda Racer at the track. The kit includes a 3.5:1 gear and high-powered Torque-Tuned 2 Motor PRO.
The Ultra-Efficient MA Chassis
The MA (Midship AERO) Chassis has its motor in the center, and features a design which focuses upon achieving outstanding aerodynamic performance. It has six individual low-friction rollers, a rear skid bar and other speedy features developed thanks to years of design experience. The single-piece monocoque frame also guarantees that assembling and keeping the car well-maintained is a task that can be performed by beginners and veteran racers alike.
