MOST IMPORTANTLY:
If it's not in the rules, and does not encompass the spirit of slower,controlled racing with realistic looking cars, consider it illegal.
This is called the "Spirit of VTA"Rule. The class is based on slower, equal playing field competition with less traction, minimal
aerodynamic aids and mostly older carpet racing technology. The final objective is close, fair,
wheel-to-wheel racing for all. All decisions of the race promoter or track owner are final.
