Basis: Design rules and figures from the cited sources; example geometry by Xem Studio
Catalog version: 2026-10-20

Sizes: see table below
- 4WD puts power through all four tyres for steadier cornering, braking and jump control on loose dirt, while 2WD is lighter and simpler but slides its rear on slick surfaces (EuroRC).
- In EuroRC's short-course comparison the 4WD truck weighed about 6.5 lb vs 5 lb and ran 10-15 vs 15-20 minutes on the same pack.
- EFRA applies the same 1/10 off-road dimension limits to both.
- Used on: Traxxas Slash 2WD and 4x4 (EuroRC comparison).
