RE: Reducing the surface area of the wings for going faster?
Rock, I must admit, I''m going through this right now on a different level. I have a wing panel that was 29 inches with 16 inches of sweep and took it down to about 24.5 span and 20 inches of sweep.
Original airfoil was naca 008 root 22.125 and tip naca 0012 about 10 inches.
Same root, tip naca 0010 8 inches.
Goal of course to go faster.
I don''t pretend to understand everything you wrote, but I do want to hear if I''ve done something over the top wrong. The fuse width is about 12 inches wide.
