Spec Slash Class

Official Rules

ROCCK Racing

This class is intended to be a fun class for racers of all skill levels. To keep a level playing field, no performance upgrades are allowed to the truck. Only a few optional durability upgrades are allowed to the truck. Ideally, a Ready-To-Run Slash, with a transponder added, can win any Spec Slash race in the hands of the right driver. 

Allowable Models: This class is open to any RTR 2wd (Brushed, 12T) Traxxas Slash, as well the Traxxas Slash Unassembled Kit (58014-4). 

Cheating: Cheating diminishes the joy of the class. Do not ruin it for other racers by being dishonest. If you are caught cheating, you will be banned from the class, and likely from racing at ROCCK in the future.

Class Race Fee: $15
