OK, here you go. The Davis wing was extremely thick in cross section just behind its leading edge. It resulted in a distinctly downward sloping profile on the upper wing root that is so steep it looks concave in profile towards the trailing edge.
The pics in the post above show it. This one does too (ignoring the shadow):
And this one too:
Look at how thick the wing is just behind the leading edge and the sharp downward slope of the wing at the wing root towards the trailing edge.
And here too:
Instead of that, HB gives us this:
It completely lacks the dramatic high shouldered leading edge / steep downward slope of the trailing edge at the wing root of the real thing. In fact it actually appears to have a convex profile from leading edge to trailing edge on the upper surface, which is simply wrong.
It looks to me that the main error is in the wing being too thin in cross section just past the leading edge
Look just how thick the Davis wing actually was. It was one of its most distinctive features:
It appears the wing in the model is simply too thin in cross section just past the leading edge which flattens the slope from the leading to trailing edge at the root giving it the wrong profile:
I can't unsee it. It's the single most distinctive aspect of the plane to me.
