Bug HLG

I did it with out recalculation. I built the wing on the copy of the plans and just installed the rod in the first and last rib. Then I placed each rib flat on the plans and marked where the rod crossed the rib to know the location of the hole. That way I did not decrease the strength of the wing with less ribs per/span. --- In BugHLG@y..., Allan Wright <aew@m...> wrote: > Actually, if you don't add any ribs, and just stretch the wing by moving > all the ribs out proportionally, you can use the holed on the plan, you > just get a different curve to the leading edge.
