I would say you are probably right. My ribs have a normal leading edge radius instead of a long gradual one tapering back. But if I have all the covering stripped off I have the one time option of making a solid leading edge. Something I want to think about.

Ron,
I start the rib profile change for about the forward 1/3rd of the rib. Your experience may have to do with having an abrupt change ot airfoil cross section. My finished model looks about like the full scale. This may explain your unhappiness with the sag between the ribs. As to my not liking iron-on...I started this hobby too many years age. I don't know how to use it.
