The motor list for E.1 and E.2 is confusing.

S-can only in E.2, Revo motor in E.1 and E.3 but not E.2.

Wouldn't it make sense to limit the motors in E.1 to 20k max, as you say they're much smaller than the other two events and on much narrower tyres.

The motors in Event 1 are intended as an open Class to allow for the Revoslot & Slot it standard cars, thats why it allows up to 21K Max.
E2 is specific to in line Scalex modified cars so is limited to only S-Can Max 21K motors
E3 is also an open class and includes long can motors and max 21K
