I have been considering this, but I haven't messed with one since we used one on our Formula SAE car back in the late 80s. My initial thought when I was pondering it was how would you go about deciding how to pitch the prop, as I believe the prop pitch is based on available HP at a certain rpm. (I would guess pitch it for cruise power & pick a prop RPM, say 2500? but how would it behave on takeoff?)
