Terry,
I like the wing w/ dihedral, combines 3 things ---the roll stability of the fin, the downforce of an inverted wing and drag brake when rotated and it's in the right place. Detail is not real clear but the bottom surface of the horizontal wing should be convex (wing shaped) and the top should be flat and the near vertical "wing" should be convex on the interior surface and flat on the outer surface (left wing rolls body right and right wing rolls body left. Lift increases the more the body rolls (self righting or one wing counter acts the other hopefully to keep it shiny side up. Downside-- if one wing fails the other will cause the vehicle to roll. How will these act in a strong side wind? The near verticals should probably have a short chord length to minimize there area to cross wind?
Hydraulic control for the air brake function?
What is the current frontal area? (with the correct engine diameter?
Fewer comments, I guess folk are busy getting ready for SW!! I've been busy..
