Beetleweight rules ?

[Ocracoke]

The only real rule difference beetles have compared to other weight classes is allowing 2 robots per driver.

Wouldn't that also be at the discretion of the EO?

The rules, as pointed out, apply to all weight classes unless the rule specifically state that they only apply to a specific class (so off the top of my head, inverted links only apply to Heavyweights for example and the types of allowed transmitter).
