What did you use to push the hinge into the slot with after you applied thin ca???
seems like the hinge would adhere to what ever you were holding it with.
Also, this would be a weak bond, although you are having success with it.
Be carefull of your control throws, if you have no gap for flex, one would
summize that the hinge would be in jeopardy of fracture not to mention you
are cutting your performance envelope with decreased throws.
Have fun flying, and stay safe.
