They always have in the past and I'm sure they will continue to do so. It is competition and people will take full advantage of the rules. Right now planes can be built under 11lbs, some even under 10, and that includes electrics. Getting a cheap ARF is going to be tough, but I'm sure someone will step up, but regardless, even the other stuff isn't that expensive compared to other disciplines.
Forgive my ignorance but what is the advantage of a slightly larger 2x2 bipe over a 2x2 monoplane? Aren't monoplanes inherently better flying planes than bipes to begin with? If not, then the let the guys fly what flies best within that size
