Before reading the manual, rigging the wings seemed like a major undertaking. After a couple of readings the mystery began to clear. It went something like this.
"Hey, I never noticed the factory pre-drilled a hole in the trailing edge spar. I get it, pin that spar, position the wing, and drill a hole in the other spar to match the... Wait a second, how am I going to see through the front spar to match drill? Ah, that's why the reference measurements were made to the second mounting hole. But there is absolutely no way am I going to get the hole in the spar perfectly positioned. Oh, that's clever, drill a small hole, shape with a file, then ream to a perfect fit. These Kitfox guys are pretty smart cookies."
As when using clecos for the first time, mounting the wings will feel like I'm really building an airplane. A chance to step back from looking at individual trees and see the whole forest as it were.
