Description
The Tamiya Mini 4WD REV Series No 13 Razor Back FM-A Chassis is an assembly model kit designed for high-performance shaft-drive 4WD racing. Its gunmetal ABS body blends the tough appearance of a maned boar with hot rod-inspired styling, creating a unique racer based on the Best Award winner from the 2018 Mini 4WD Design Contest. Carbon-style accents and metallic decals bearing the machine name and logos further enhance its competition-ready look.
This Tamiya Mini 4WD model is built around Tamiya’s FM-A chassis, featuring a front-mounted motor and aerodynamic construction. The forward-centered weight distribution is intended to support stable performance on tracks with frequent uphill and downhill sections, while the air intake assists with motor cooling. A 4.2:1 speed gear is included, and assembly requires separate tools, making this a hands-on racing kit for Mini 4WD fans aged 10 and above.
