Nice Alex, you have some skills. I am gonna try and have the rib templates I have scanned so I can keep this airfoil constant on the plans. I am currently flying a large turboprop aircraft with foam core wing and am really confident in the strength of the build, so I will probably go that route. If I could figure out a way to get these templates to you I would love to see how you work with them to come up with a built up wing plan.
