I use a lot of the Dubro flat nylon hinges. I use 5 minute epoxy to set them and I have never had a problem with them. The ones that have pulled out in a crash have taken huge chunks of balsa with them. I do things a bit different though when I use them. I prep each hinge by applying a fine line of wax via an Xacto blade and alcohol burner prior to setting the hinges. I have some red sprue wax from my jewelry days and it is somewhat flexable and the red color is easy to see. I flow a very small amount of this wax along the hinge line, from both sides and then set the hinge aside while I prep the rest. I apply the 5 Minute expoxy with a thined hardwood stick so I can push some in the slot prior to setting the hinge. I then wet both sides of one tab and push it into place and wipe down any squirt out. I can do four to five hinge halfs at a time before the epoxy starts to kick. This is important as you set all the hinges in one half of the wing then the next epoxy batch installs the aileron. I come back with an xacto knife after the expoxy has started to kick but before it really hardends and scrape any flow onto the hinge off. The wax prevents the epoxy from getting into the hinge pin, and is still stiff enough that you won't smear it around on the wood like you might with vassoline. It really cleans up nicely. And as I have said, I've never pulled one out, even in a very hard crash.

I've got 1/4 and a 1/3 scale kits waiting to be built, and on those, I'll use the Robart hinge points. I'll set them the same way though.
