Current version fits 90mm (M) wheelbase shells. ### Update 8/26/20: I've released a 4WD chassis, available [here](https://www.thingiverse.com/thing:4579896). 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 ## Parts List | Part | Quantity | Notes | |---|---|---| | M3x20mm button head screw | 7 | | | M3x14mm button head screw | 2 | | | M3x10mm button head screw | 8 | | | M3 lock nut | 17 | | | 625 bearing | 4 | | | 130 size brushed motor, 2s compatible | 1 | | | SG90 micro servo | 1 | | | Compression spring, ~4mm OD, ~6mm length | 2 | For front suspension.
