Some fundamental ideas. The very idea of the mixed lifting body and wing combo was discussed at homebuiltairplanes.com many years ago. System is based on Cm negative and Cm positive airfoils compensating.
Insane amount of research has been put to this to find an efficient lay out for this. I started a rigorous research in 2007.
The foil has L/D of 214..so it is a high lifting foil.
