After finishing the wrong side of a couple skins and nearly starting over, the ailerons are finally finished. They were a bigger pain than expected. The nose skins put a lot of force on the spars, so the skins were very warped when finishing the trailing edges (I read this is common). Well, they finished off just fine, but took a lot of extra effort to keep straight. My Dad was in town for his 81st BDay and helped a lot. See the one picture with my son and dad while riveting the spars. It was great to have them involved!!
