For a low wing to acheve that neutral some degree of dihedral or dihedral effect is necessary and of course a midwing with a flat wing is already close to the neural point.

Yes Al gunn I you are quite right about the low wingers. That gentlemans picture of his low winger I posted above worked out very well but he had built one before that with a flat wing. I had done the initial test flying on both and the flat wing original was terrible being unable to stabilize in level flight constantly falling off in both directions. The second ships with three inchs dihedral each side at the tips made all the difference in the world and become a very pleasant flyer. That ship has even piggy backed 118 inch eight pounds gliders quite stabile and a pleasant roll response.
