At this point it's difficult to put the genie back in the bottle. Between doing away with static judging (which used to count for half of your score) and lowering the breakouts, it's not surprising that the planes have slimmed down a bit in order to retain a competitive margin. Sure, you can go fast enough to win with a scale airframe, but who wants to work that hard when you don't have to? I'm not saying it's right, but it's somewhat understandable. The rules only require "....approximately resemble.....", so that's as hard as anyone has to try.
