I realize that the goal is to have the trim drag at a minimum for cruise AoA, but once up there near stall you would not be worried a lot about fuel economy, ya think?
Agreed, gums.
Something that would give the pitch-down moment at high alpha, but would not add drag in the cruise. I haven't come up with anything yet. The closest I have come is the idea of some surfaces protruding from the new tail cone. Having such a long arm would mean they wouldn't have to be too big and ugly.
