Hi everyone
This is my first post hope it helps someone as I have gained loads of info by reading these posts. I am building an f22 and have found that if I smear some 5 minute epoxy on the foam before I stick my hinge tape, it makes an incredibly strong bond. Give it a try on some scrap

Great tip Biggles, thanks for sharing with us. I noticed that too. I squeegee the epoxy on the plane, so it is really thin coat. Then Dave turned us on to some really good tape (scotch Filament packing tape) that is so sticky we no longer needed to do that.
We found two more uses for the “squeegee a really thin coat epoxy on the plane” thing
1) Sand the whole plane lightly with 200 grit, squeegee a really thin coat epoxy on the plane. Sand it smooth with 400 grit sandpaper, then paint it. It looks like painted metal; flawless, very stiff and strong.
2) To reinforce the nose, the lead edge of the wing, around landing gear, or the bottom of the plane.

ah yes I wondered if that might work, thanks for that I will try that on my second plane after I have crashed this one

Hey quick question when you put the epoxy on for the hing, do you wait for it to dry then put on the tape or put the tape on as its trying?

I'd put the epoxy on first, then smear it over the threads in the hinge tape. Fiberglass drywall tape works well. Foam-Tac and Fabri-Tac make good alternatives to epoxy too.
Yes, I've known that I'm "different" for some time now...
