Interesting discussion! Glad to see someone talk about why faster head speed doesn't always = better since there is always a performance window, which is what you sometimes hear around here.

I can't believe it took this long for blade designers to think the way VTX and a small select few have about planform shape! Not saying that I have, because I definitely have not lol, but it is one of those things that you go "duh! why haven't we been doing that!" The full scale blades have gone in that direction, and of course fixed wings use planform shape, twist, fences, and all sorts of fun stuff! Twist.... hmmm that would be an interesting one to study.... probably wouldn't do a 3d bird much good, but for speed blades, you could look at more asymmetric airfoil and planform geometry! (of course if it could be built cheap enough!)
