Nice job on the War Duck. How did you remove the dihedral from the wing? I'm considering converting my Nexstar to a tail dragger and would love to flatten the wing. Making it a taildragger would be easy but I'm a little stumped with the wing. If you remove the plastic coupler than you have to make a different way to attach the wing. It appears from your pictures that you retained the plastic coupler. Did you remove the metal bar as well?
