This is the path I'd probably follow.His DA-11 is a good example of his “less is more” approach.
But the Quickie doesn't stall.Quickie would stall that low. 47 mph would imply a net CL
With a canard wing up front and biplane wings in back, I wonder what is required to make sure the forward wing stalls first. Even if all the airfoils are identical and the canard is more heavily loaded, surely the flow field around those stacked rear wings has an impact on the stall behavior/critical AoA of one or both.I think either the Catto Acro-X biplane canard layout or a monoplane canard layout could work fine, ditto a Mignet tandem or something like the Autoplum. Of them all, I think the Catto layout is most appealing. It’s easy to imagine an ultralight-style, ladder frame of bolted spar tubes and bracing wires, identical sheet metal ribs, and Oratex or sewn Dacron fabric going together very quickly.
