I used to use Epoxy but with the advent of the Pacer HInge Glue p/n PT-55 which is water cleanup I dont have any problems. It is just as strong. Believe me I fly fast and larger planes and have not had a hinge failure! (YET) The water cleanup feature is great. Most LHS have this glue. It also comes with a long tip injector. I use the Klett nylon hinges and then run a 1/32nd music wire the length of ailerons , elevator etc. so they are removable in event of a repair requirement.
