Use CA (Super Glue) for the hinges as those hinges are made to "wick" the CA down thru the hinge. Your local hobby shop should carry some thin CA. Get a minimal gap between the 2 surfaces you are hinging (be it ailerons, rudder or the elevator) then carefully deflect the surface downward and put 3-4 drops on each hinge. Turn the surface over (again, ailerons, rudder or elevator) and put 3-4 drops on each hinge again. Let the CA set for atleast 10 minutes, then you can move the surface up and down, to "free" it up. Also, a fine tip applicator helps avoid getting the CA all over the surface, as an example, I use an insulin syringe to get the drops right on the hinge itself. It should tell you somewhere in those instructions to use CA only, never epoxy the CA type hinge. Hope this helps
