I thought about that a little. I am planning on using the plans as a reference. Establish a line on the outer panel, then place the root rib, the blanks, then the tip rib. I think you are right, but not having it in front of me at the moment I cant verify. The main thing is to get any washout (TE) and leading edges lined up too. I was going to leave the root rib out until ready to mate up to the wing center section so the angles come out correct. This project just got bumped down a little further due to a Waco. At this rate, I'll have to live to 150 to finish all the builds I want to do.
