Whoops! I forgot.
Wing mating. You actually set the dihedral in two places. One was setting the angle on the joining ribs and the other was using the dihedral brace. I ended up with 1 3/4 inches wing tip height.
I used 30 minute epoxy. Any spaces I filled in with Med CA
Mine went together quite well but it is a hair raising experience.
