I know the rules for a factory built LSA allow for an increase in gross weight to 1350lb from 1320 provided that 30lbs is used for a BRS or floats. My question is if a plane registered as experimental with a gross weight of 1350 be flown by a sport pilot assuming the extra 30 lbs is for a BRS? I have no plans to actually do this so I can't provide an example, just curious. My guess is no but you tell me.
