RE: Used epoxy instead of CA, now what?
It should be OK, but for added insurance, "pin" the hinges in place. Drill a 1/16" hole through each side of each hinge, from the top of the wing (stab, fin) and aileron (elevator, rudder) through the bottom. Then push a common round toothpick through each hole, trim the toothpicks flush with the top and bottom surfaces and put a drop of thin CA on each end of the toothpick.
