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
