I've chosen the semi-symmetrical airfoil for the build. I decided build the TE out of single piece of 3/8 x 1 1/4" pre-shaped balsa. I marked extension lines for the aileron cut outs and the cut out that is centered over the fuselage. I used a small framing square to make sure the ribs were set plumb on the spar. Once I had all of the W3 ribs set in place I installed the leading edge which I had formed using a form made with bondo & a foam profile & emery cloth. The wing uses an I beam type structure for strength. Once all of the ribs were in place I proceded to place 1/8" balsa in between the ribs to join the lower spar to the upper.
