When you are ready to install the F6111's you might want to check out this web site that Mike Schipper has up - www.my9a.com
. If you go to his Top Skins section you will see a picture of how to go about putting these in. I found Mike's site early on while working on my plane and often go out and read sections before I attempt to tackle them for real. This really helped me on these stiffener ribs because the information in the plans for this amount to zilch. Tim has the steps down in his earlier post but seeing a picture can be very helpful indeed. Not sure how long Mike will leave his site up but it helps me visualize how to go about doing things while its still available.
He is currently building a RV-10 and has a link to his progress on it as well.
