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

The U-joint parts have small built-in supports that must be peeled off before assembly. If the supports are stuck too strongly to the print, they can be easily cut off with flush cutters or nail clippers.
