RULES ARE SIMPLE, THIS CLASS IS MEANT TO BE ‘SPEC’ AND ALLOWS FOR CLOSE COMPETITION ON EQUAL GROUNDS FOR ALL. THIS CLASS IS ALSO MEANT TO SHOWCASE THE BEST DRIVER AND ALLOW FOR FUN! NO SECRETS OR ‘VOODOO’. IF YOU WANT TO HIDE YOUR CAR OR RUN SOMETHING THAT COMPETITORS CAN’T RUN. THIS IS NOT THE CLASS FOR YOU. IF YOU WANT TO HAVE FUN IN A CLASS WHERE DRIVER AND SETUP ABILITY IS KING, YOU HAVE FOUND THE RIGHT DIVISION.
Because the cars are equal you need to make passes cleanly. Driving through the car in front of you in not considered a clean pass. Just because your faster does not mean dump the car in front of you. A slower car running the bottom is hard to pass! Work hard, race hard but importantly respect your fellow competitors!!
“IF IT DOES NOT SAY YOU CAN—YOU CAN’T”
**The Allstar RC Dirt Series & Race Director reserve the right to change, modify the rules as required. We also reserve the right to call you out for rough driving! **
