You should now have a spar built, assuming you can understand my instruction and drawings.

Next step, the wing panels. I always run my flutes chord-wise. The pic shows the majority of the dimensions. The strip at the tip of the 11 3/8 measure is about ½ inch wide. One side of the plastic was removed for the leading edge. Total width of the panel is 22 ¾. So you need 2 panels 35 ¾ X 22 ¾ . The 22 ¾ should run with the flutes.
