I understand your thoughts, I just play by the current rules.
Dave Platt proposed an event very similar to your thoughts several years ago. He suggested something like, takeoff (not judged) fly around "in a scale-like manner" 3-4 laps and land (not judged), for 50(?) points added to your static score. He couldn't get enough support to field a contest, even as a provisional at the NATS.
There just isn't any incentive to design and build your own aircraft anymore, being grouped together as Designer scale is like flying with a bunch of "outcasts". Where's the recognition for the extra effort? How about a 2% builder's bonus added to static? That would encourage some new designers/designs, it was enough to make modification to the jet kits at Top Gun. I still like to beat folks with their $20,000(+) prefab jets with a few hundred dollars worth of balsa and plywood, even without a builder's bonus, but if I don't enter in the Designer Class at major events, it will be dropped then where will we be, again?
Just my thoughts....
