RE: How to make a Q500 wing??
I do basically the samed as Stan. When I am applying the glue to the skins I lay a strip of Carbon cloth along the inside trailing edge of both skins. Like Stan I sand to a knife edge when cured. That is the reason I never use polyurethane glue to apply wing skins. Epoxy/carbon cures to a very hard stiff edge, Polyurethane glue will not, it stays "Soft"
