Banktoturn,

I work with a guy who has pit crewed for Rare Bear for the last several years. I'm going to pick his brain about clipping wings and the theory behing it. I don't think full scale pylon racers turn very tight so its not a drag issue but more just to increase top speed. We'll see what he says when he returns from travel.

As far as models go, a model built for pure speed would be so overpowered you could launch it straight up and accelerate vertically. Landings would be hot but if you have the room.........
