First modification is done. Because the Super Cub fuselage sides do not taper in like on a J3 I wanted to modify the plywood sides of the forward fuse into a single piece. In the stock configuration the nose of the plane is put on after the main fuselage is built. By making it one piece I believe I have added a lot of strength to the nose with no additional weight. I also pre cut the lower door from the plywood side. The rounded portion of the lower forward fuse is where the pitts style muffler will recess into the firewall. You can also see the curved piece I made by laminating some light ply around a former. The forward most portion of the right fuselage side was also shortened to accommodate for the 3 degrees of right thrust I am building into the plane. The plans show no right thrust but I have 3 degrees built into my 1/5th scale, and my friend's H9 Cub has 3 degrees, and both fly true so I am adding it to this model.
