Browse available alternativesHeat Edge is the second Mini 4WD PRO model built on Tamiya's MA (Midship AERO) chassis, following Blast Arrow. Its body draws on modern prototype racing car styling, with canard-type front fenders and a shark fin running from the cockpit back to the tail, finished in bright red with flame and chequered-flag graphics.
Low-profile tires sit on sharp fin-spoke white wheels for contrast against the red body. The single-piece monocoque MA chassis carries a centrally mounted double-shaft motor, a 3.5:1 gear ratio, six low-friction rollers and a rear skid bar, and is designed to be simple to assemble and maintain.
