VTA Class Rules

Chassis


Any 1/10 all-wheel drive sedan with 4-wheel independent suspension.

Starting out, need a car:
ATVA is a class that can use baseline/ old kits as like old race cars of its time. So, you don’t need a high-end kit with VTA racing as the minimum weight brings the kits back to an equal playing field.
The old races where heavy that’s why 1500 grams is set as the minimum weight.

  • HPI or others suitable, Australian Muscle cars. No Slanted or modern Japanese cars etc. No 2-seat sports car (Chevy Corvette is Ok, just. If you really have too.)
  • AUS VTA is about Australian and USA Muscle cars. Not European or Asian cars.
