Tamiya 18636 JR Heat Edge MA Chassis 1/32 Mini 4WD Kit - Compact Racer  [18636]

Overview of the JR Heat Edge model

The Tamiya JR Heat Edge 18636 brings prototype car cues to the Mini 4WD PRO Series, featuring a streamlined shell built for aerodynamics. Eye-catching bumper canards and a pronounced shark fin help keep the car tracking cleanly at speed, which is useful on technical layouts.

Understanding the MA chassis setup

The MA chassis used here is injection-moulded from tough grey ABS, giving a strong base for race use. Its double-shaft motor arrangement promotes stable power delivery, and the chassis accepts common upgrade parts so you can adapt gearing, motor choice, and handling components.

Upgrade paths for better lap times

Performance improvements typically include higher RPM motors, alternate gear ratios, and tyres matched to your track surface. Small changes such as ballast placement and suspension add-ons can make a noticeable difference in handling through corners.

Assembly and preparation advice

The snap-fit construction keeps assembly quick for newcomers, while the included 130 motor and decals let you get on track after basic setup. A small Phillips screwdriver and plastic side cutters will speed the build and reduce stress on parts.

For tuners and club racers alike, the Tamiya JR Heat Edge offers a flexible package. Its aerodynamic body and MA chassis make setup tweaks straightforward for different race formats.
