I liked my new Slowly pretty well, but I couldn’t help but wonder how it would fly with a straight (or, at least, straighter) wing. So I built a second wing, using the same dimensions, but without any dihedral whatsoever. I made the ailerons really small for some reason that I can no longer remember – 1″ deep and about 7″ wide.
Flight tests on the straight wing were promising but the plane really, really lacked stability. I decided a few degrees of dihedral should help out.
To add the dihedral, I cut through the wing at the front and back, while leaving the center section intact. Then I gently bent the wing to the desired angle, and added thin wedges of foam to fill the resulting gaps at the front and back.
