We're apparently both in the same boat here. I'm not at all sure if my design will be dependent on delta lift or not. I have not settled on an airfoil yet and I guess that's a vital part of the equation. However, whatever I choose, the internal structure needs to have some 'form' in my mind. Although I started with the D.D. as a basis, it's wing design does suit my needs, it barely has a spar of any sort.The big question is if you're planning on delta lift as part of your flight envelope. If you're going to be going fast enough (relative to wing loading) and at a low enough angle of attack that delta lift is not a major factor, normal wing design should apply -- although you'll pay the cost of a low aspect ratio. (This is where I am at my design... stall without delta lift is at 19° AoA, and I have no need to go beyond that.) If you need delta lift... dunno.
I've spent some time today making a simplified model of what I have in mind. My question would be, will spars of this configuration be able to prevent any twisting? bearing mind that the outer wing is removable. I'm thinking of wooden spars and foam ribs on 3-400 centers. The spars will won't be as high as in my model and will be boxed where they enter the stub wings.
