How do i use these Hinges the Glue on the hinges dry before i get the whole hinge in the slot.

The CA hinge needs to be in both surfaces before any glue is added to it. It's my understanding that once glue has been put on the hinge, you can't glue it again, so any hinge that has had glue on it will have to be replaced. Put the hinges in all of the slots on one surface, then line up the slots on the other surface and slide it onto the hinges. Once everything is set where you want it, put 3 to 4 drops of thin CA on the top side of each hinge, then turn the surface over and put 3 to 4 drops of thin CA on that side of the hinge. There should be step by step instructions on how to do this in the manual that came with your plane.

I would like to add a few things to that. After the hinge is in one side push a small T-pin through it at the hinge line. Otherwise it's possible to push the hinge to far in while putting the other side on. Also when putting the CA on it do drops with the wing tipped forwards and backwards. Gravity will help with the wicking process. Like rtn said if the have glue on them throw them away. If you need more Great Planes makes a good one.

AND: Never use anything except Thin CA on CA hinges. Medium and thick will not wick into the hinge material properly.

Some people like to draw a line with grease pencil or crayon for the actual flex line (the part between the fixed and moving surface... both sides of the hinge) The grease or wax prevents the CA from staying in that portion of the hinge's fuzzy coating and this can make the hinges last longer.
