RE: hinge glue?
I have found using 30 minute epoxy and a drinking straw works the best for me! Mix up the epoxy, quickly pushing the straw throught the epoxy over and over fills the staw. Flatten the end of the staw and insert it into the hing slit. Then just squeeze the glew out of the straw into the wood. Perfect fill with no mess.

RE: hinge glue?
I tried using Pacer's (Zap) Hinge Glue on a wing that had a balsa TE behind foam and the glue would not dry. Pacer said that this was due to there not being any air gettinjg to the glue, despite no statements regarding that aspect in any of their instructions, etc.!! I have had very good luck using Gorilla Glue for Robart hinges, as well as with using Epoxy.

RE: hinge glue?
I use Gorilla Glue as well. Never had a hinge failure. There is a great how to here [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=269]How To Install Robart Hinge Points[/link]
Time is the key. When I am hinging control surfaces it takes me 2 days. Use vasoline to protect covering and hinge knuckles, move hinges every so often and you can pick off the dried glue the next day.

If you use Gorilla glue, your fingers will be as black as a Gorillia.
I like using a trash hinge with extra holes in it, to slide in the right amount of Epoxy for the real hinge later. Use 30 minute Epoxy.

RE: hinge glue?
Canopy glue is all I've used on Robart-style hinges for years with good results. I've never had a problem w/ the glue not drying, but then - I haven't used them on foam wings either.
I like the fact that you don't have the potential for a finish-destroying mess you get w/ epoxy or polyurethan glues and that clean up only takes water.
But proof is in the pudding, as they say. Make up a test: install a Robart hinge into a scrap peice of 1" square balsa, leave it to dry overnight and then try to remove the hinge (with plyers). You'll find that the balsa block or the hinge will be destroyed long before that glue joint fails. Unlike epoxy, canopy glue is made to adhere to plastic and sticks like crazy to the stuff.
