OK you assemble the flight controls together then add a drop of THIN CA and it will wick it's way all the way to the edge of the hinge. A tip to use is to put a pin through the center of the hinge to make sure it is centered on the flight control. Once it is assembled pull the pins out and bend the surface a little farther than it would be in flight. Place 2 drops of, I'll say it again, THIN CA on what you can see as a thin strip of hinge watch it wick away.

BTW Once they are in they are in, I have never been able to succesfully remove one without tearing away wood in the process. Also I believe most hinges are treated with a chemical that slows down the curing process of thin CA to allow for better wicking action.

I hope this helps.
