You are correct about that. I like the look of my Hydeaway but after a few contests flying against the more modern designs it became very obvious that I was at too much of a dis advantage. The newer airplanes work so much better on speed management and rolling. The pilot workload just seems to be much less. With that in mind there was lots of thought put into this design before construction began. I wanted a biplane for the added wing area. I did not want to put the upper wing onto a set of cabanes or pylon because that would mean moving the canopy back. In theory the more forward canopy will perform better but with a Bipe it need not be as far forward as with a mono. For simplicity of fabricating the tooling and fuselages I wanted a single hatch. At that point it was decided that the upper wing needed to be plug it. The fuselage sides needed good flat area. This helps with rolling and knife edge. The wings need the correct area, taper and thickness. Here is where some original thinking comes in. From the root to the intermediate section, the cord is reduced but the thickness is the same. The result is that the intermediate thickness is a thicker section. The same goes for the tip. The tip is not only a thicker percentage airfoil but as the wing progresses from the intermediate section the TE gets thicker. I am hoping that this will yield better tracking and slow speed handling. The stabs are rather thick as well. The templates used for cutting the stab cores are the same as the wing intermediate section and the tip section, although the tip template was dropped some on the CL yielding a slightly thinner airfoil. The lower wing is set to .7 degrees and the top to zero. My thoughts here is that while in level flight, the bottom wing is doing the majority of the work. This lesson was gained from sailplane experience where an airplane with higher wing loading will penetrate better. Any change in AOA however will bring the upper wing into play and the advantage of more wing area will come into play.

This is pretty much how I came to what you see to this point. Eventually we will find out if all my theory is correct or not.
