The official 1/12th scale classes at MARCCA are:

stock (27 turn motors)

open (everything else, including all brushless motors)


As always, 3 cars define a class. While we encourage conformity to a class, no one will be turned away from racing on any given race day because they don't fit the class structure. If not enough entries show up for 1 class on a particular week, the drivers will be allowed to run in the other class. In the case an open class entry runs in stock, the entry must try to conform to stock as much as possible (e.g., acceleration and throttle adjustments via the radio).
