RE: Repair of a fully sheeted built up wing.
I have found out over the years the hardest part of fixing a plane is the first cut into a wing tail or fuse after that its easyer than you thought .This does not mean i jump into repairing them either ,i leave them sit for a while till i miss them like you have . I cut or repair them sooner or later and then ask myself why i left it in the corner that long when it was this easy to fix.lol Good luck and happy flying with your old, knida new plane.

I always figured one had to let a crash sit in a corner for a couple of weeks before starting on the repair. I'm pretty sure I do this to teach 'em a lesson!

Thanks for the replies. I was afraid the glue on the sheeting would hold tight enough that the ribs would crack. I'll tear into it when I get home. I really appreciate your answers. You are right Gray Beard - sometimes I over think things.

Tip, when re-sheeting, use Gorilla glue. You can dampen the sheeting to easily conform to the contour, and the glue uses the moisture to cure. It also fills gaps as it cures. Your plane will be better that it was when new. I use stretch wrap to hold the sheeting in place while drying.

AA5BY... Thanks for the pics of your wing repair. That's a good illustration of what I was talking about using temporary spars. Since that wing (the 4-40) had a constant chord, another method of repair would have been to cut out one wing rib to create a pattern, cut new ribs, and from there reassemble a whole new wing. The last major repair I did involved a Skyshark Avenger with a fully sheeted tapered wing. Considerably more difficult repair.
I really should take more pictures.

I have found that the glue on most ARFs is not as good as we would like it to be. Should not be a problem.

It was built back in the late 70's early 80's. Here it is in better times.By the way - anyone know who made the kit?

RE: Repair of a fully sheeted built up wing.
I was quite active during that time but don't recall a kit looking like that. I'd hazard a guess that it is a scratch built stick design that was initially built with painting it in mind (hence fully sheeted wing) but at some point either changed hands or was rethought to use film covering.
