Note: Some parts in this design are quite challenging to print - make sure you have a well-calibrated printer before attempting. For best results, print the parts in ABS or PETG.
For grip racing or a simpler and cheaper build, my RWD chassis design is available here.
Features:
- Fully indepdendent sliding suspension
- 4WD drivetrain with printed U-joints (no differentials)
- Mid-mounted battery and motor - approx 50-50 weight distribution
- Parallel steering geometry for drifting
- Uses common M3 fasteners, locknuts everywhere
- TPU printed tires
