Oh I don't know. Low wing loading and slower flying are still bonuses without all the self righting capabiltiy of the dihedral. Got one wing almost done! Still have at least an hour left on it though then it's on to the next one. Should go much faster! I was a little disappointed with the fit on some of the parts though, especially the web braces? The 2" pieces that go between the the ribs. Mine were short. I had to add small balsa braces to augment them. Seems like I shouldn't have to do that but my wing still looks good.
