Don,

It's interesting that there is a plane that seems to be using the fuselage/canopy shape to some advantage. It had occurred to me that you might want to build up as much of a lifting surface for knife edge flight as you could get away with, and fly the whole course on knife edge, using the elevator to steer. Apart from the inefficiency of supporting the plane's weight using something other than a real wing, it make sense, since the force in the turn is something like 10 or 20 times as much as required to keep the plane up. You could even put the elevator on the rudder channel, to make it more natural. I'm sure that the landing gear could be configured as a pretty decent lifting surface for the bottom ( or 'right' side of the plane, if you visualize it in knife edge flight ), and a prominent canopy, or even a fin-like surface behind the engine could provide lift on the top/left. Maybe a little balast in the left wing for stability, and you could roll it over right after takeoff and fly on your side.
