The wing frame is nearly complete and going together well. The full scale plane uses a NACA 23018 inner section and 2412 tip section. To keep the wing reasonable scale looking, I used a 23012 changing to a 2412 at the ailerons. There is one airfoil former section that is a bit modified during the transition. Sometimes I wonder if I should have just used a single section like an E197 though. The two sections used in this wing are quite different, and it becomes a bit difficult to set washout without some flexing of the LE. An overlay of the two sections shows the difference in entry point locations, as well as other features. Irregardless it's a good bit of work to properly sheet a light frame without stringers to begin with, so it makes little difference in the end. I may add a few stringers, mostly for the purpose of making slightly more rigid frame. It would then be a bit easier to sheet and avoid having any warps or mismatches across the panels.
