RE: kavalier surface throws
I debated the dihedral decision and decided to go with most of it. It isn't much to begin with, and the plane always had a great flying reputation. Building a new wing without it is always an option. Most of it is basically building from scratch anyway, so I will only lose tme cutting out ribs. I do think it will fly differently without dihedral, and that question will always be there until I try both.
Gizmo, did you fly your with the CG all the way aft?
