This is a 1/28 scale RC chassis designed to be compatible with Kyosho MINI-Z body shells. Current version fits 90mm (M) wheelbase shells.
Update 8/26/20: I've released a 4WD chassis, available here. The 4WD version is optimized for drifting, while this one is better for grip racing and is cheaper to build.
Features:
- Independent front suspension and hinged rear suspension
- Ackermann steering geometry with 45 degree max steering angle
- Uses common and cheap parts (625 bearings, M3 hardware)
- Low part count and variety - only 3 different screw lengths needed; locknuts everywhere
