Battery Specifications: ROAR approved 7.4v 2 cell LiPo hard cased, 6000mAh MAX limit

Ride Height Specification: Minimum ride height is 5mm on Carpet

Weight Specification: Minimum 1450g in race-ready trim

Race Specification:

– 5 minute qualifiers

– 8 minute mains

– Larger Races IFMAR-type starts are a better option. All smaller “club” heats and mains should be straight-up starts, with random sorts for each heat if desired. Non random sorts should shuffle starting order for each heat. Optional Main Variations:

– 12-20 car A-mains, depending on car counts.

– Invert qualifying order based on random hat pull (top 6-10 cars).

– “LeMans” type starts where all cars are lined up on an angle to the racing line in order.

– Run track in reverse rotation for mains.

– Rolling starts

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.
