Kumamon goes all GT!
This is a Mini 4WD racer assembly kit which creates the Mini 4WD Kumamon Version GT. The classy Silwolf body evokes the style of real life GT cars. It has lightly tinted (light smoke) window parts to show off the pre-painted figure inside, which is none other than the super-popular Japanese mascot of Kumamoto Prefecture - Kumamon!! Dedicated metallic stickers are included to decorate the kit, which is based upon the aerodynamically-superior MA chassis - here, it is molded in black with contrasting bright red A parts; these just so happen to be Kumamon's signature color theme! Fluorescent yellow fin-spoke wheels add an extra splash of color. The model includes a 3.5:1 speed gear and high-spec 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.
