My method is to use Gorilla Glue, this glue spreads out and anchors the hinges in place. I'm flying also up to 100cc aerobatics and there you need something what is proven and secure.

With a small stick (longer then a toothpic[8D]) I drop some in the hinge hole and cover the inside of it. Then I cover the hinge and put the hinge in the hole. The hinges are oiled with light oil. After a while the Gorilla Glue starts to expand and try to cover your hinge - a Q-tip with acetone will remove quickly without smears the glue.

You have to have an eye on it for the first 30 to 45min after that it's fine. Some guys cover the trailing edge (wing) and leading edge (control surface) with blue masking tape --- I don't.

The advantage is the expansion of this glue in any direction. the epoxy just goes with the gravity. Disadvantage : It takes just a little more time and effort BUT it's worth it!

happy landings
