Huh, I just saw a flock of raptors flying SW, towards Cherokee county. Six black vultures.
Some parts of the Raptor are massively overbuilt. Other parts are underbuilt. I don't know which the ailerons are. Their weight suggests overbuilt. But they could have a poor choice of laminations, making them heavy and soft...I'd bet that aileron is plenty stiff in torsion - one of the side effects of a significantly overbuilt structure. As a contrast, the Hiperbipe has full span flaperons of very narrow chord, folded aluminum skins with no ribs, and a counterweight only at the tip.
With Raptor, I'd now be looking at point loads at the spade/aileron interface. I can see that getting nasty with all that weight on a long arm.
