here is a good question for you guys I have been looking at the manual about building the wings for my kitfox 1 and it states place the wing strut attach brackets on the spars, and rivet them in place before rigging, it gives a measurement of like 86 1/2 inches then it says drill, debur, glue and rivet. Now to me it makes more sense to hose clamp them on, then after rigging attach them. like I see pictures of people doing. what do you guys think
