Which fuse version you building? Larry had at least three different versions. I have Larry's computer files so if you have instructions for a different version, I should be able to help. First version is just balsa fuse. Second version is sheeted
from the back of the wing with the sheeting at 60 degree angle and third version has convex formers sheeted with either 1/32 or 1/64 ply. The last version makes a very stiff fuse which was the idea. Each version was suppose to be stiffer than the previous.
