I know the dihedral isn't a problem per se. The wing is pretty straight (by design). The wing screws were tough to get aligned, given the other fitment issues of the wing. What is nagging me is that it is only about 1/8" up in the back, but it is up because the trailing edge is extending just past the back of the saddle, and resting on the back of the fuselage. It's hard to see in the pic because the offending side is on the other side of the picture. The two wing halves are about 1/32" or so from being even at the trailing edge.

I guess I can sand the back a little. It shouldn't take more than a 1/16" notch or so to get it to sit down. Then I can see what else may be off. I guess I could try to shim the wing (which will be easier and hidden). But it sounds like I first have to commit to getting it in the saddle cleanly.

Thanks for the suggestions. I guess you really do have to shave and sand and cut and bend a little to make these things work. I'll have another go at it tomorrow (or maybe when I'm rested next weekend. Not giving up yet!

Thanks for the help.
