Yesterday I sheeted the second bottom wing panel and today they have been joined. The joiner is a peice of 1/8" vertical grained balsa with 3.7 oz glass on each side. As you can see it ties into the wing skins. Depending on weight, I would like to glass and paint all the wood surfaces. Usually on something like this I will glass with 3/4 oz cloth with an 8" overlap in the center and then an additional 10" layer of 1.4 oz in the middle. If I end up having to use iron on film then it will be 2 layers of 1.4 oz cloth 8" and 10". I think I have it straight enough while the epoxy cures.
