Or perhaps lack thereof.

Thinking about the FacetMobile and the tail design on the Sonex series of aircraft.....

Suppose you use all the vortex tricks, and simply make the center portion of the wing flat with the ability to droop the leading edge and trailing edge like so:

Very easy to build in aluminum.....How much performance will be lost from a lack of airfoil?? The wing is thin.... It is an "airfoil"-just a really bad one. But the primary lift mechanism is from vortex flow at "high" CL. I figure if a Regallo wing can fly...so can this. As long as the area is large enough. Obviously a smaller optimized airfoil wing will outperform...though at lowish Reynolds number bad things start to happen with that type of wing and it's much harder to build.
