Today I drilled the flap ribs to the spar and to the bottom skin. I also fabricated the FL-708 spacers and spacers to go between the ends of the ribs and the "skin spar" on one flap. The other flap didn't need them. Finally, I marked a 1/4 inch line off the edge of the flap hinge in preparation for drilling it in combination with the rear spar and bottom skin.
