Well maybe saying Zero is misleading. As I said and did above 1" block under each wing tip when gluing the halves together makes the proper dihedral. At least that is always what I have been told. I know on my KAOS plan it says 3/4" blocks under each tip. It is really the dihedral created by the airfoil becoming smaller and smaller as it goes out to the tip. When I had a straight edge on the center line of the trailing edge it was straight.
