Notes
- 1/12 on-road 'pan' cars run a moulded body with either a wing or a short spoiler, sized by rule. EFRA allows a wing 172 mm wide whose profile fits a 52 x 26 mm box, or a spoiler up to 25 mm high and 35 mm long, with side dams up to 72 mm high.
- As on full-size cars, a spoiler is a body-edge lip while a wing is an airfoil with flow over both faces (CompetitionX).
- Used on: 1/12 electric on-road cars.
- The file is a reference example built by Xem Studio from the numbers above (EFRA 1/12 maximum box.). Sizes the sources do not fix are illustrative; scale the example to your own vehicle.
