Wow, in one sentence your manual says to check carefully that all hinges are glued to the aileron, and in the next sentence it's telling you to glue them. That doesn't really make sense to me. My bad man, looks like you followed the directions as you should have. I think we've found the problem. It definitely looks as though those are CA type hinges. You The wing halves should have been epoxied together, and the torque rod should have been epoxied in. Always make sure the torque rods are lined up properly (by bending if necessary, which it sounds like you did), and then epoxy them in place. This is done simultaneously with CA'ing the hinges in place. The epoxy will cure in the torque rod hole, and make a nice tight fit, with no slop. You should call the manufacturer and ask for a replacement. I don't know if it will do you any good or not, but they have definitely misled you in your manual.
Sorry about that dude, but I think that is the problem all together. If they won't replace it, then when you rebuild it, for sure take those hinges out (or cut them off if they are still stuck) and re-hinge the aileron. Cut your own slots with a razor, putting 4-5 hinges in each aileron. Then, match all of the hinges up, make sure you have free movement, press the ailerons and TE of the wing together firmly, and then fully deflect the aileron surface downward--this will expose the hinge for glue, and give you all of the gap you will need. Apply about 2-3 drops of THIN CA glue to each hinge. Wait a minute. Do the other Aileron. Wait a minute. Turn the wing over, fully deflect the ailerons upward and repeat the process. Allow the glue to cure for a couple of minutes ,and start flexing the crap out of both ailerons. You will have a joint that will be as flexible as you need for a trainer!
Even if those hinges will pull out, please cut and use different slots for your CA hinges, as the epoxy that cured in those slots will not allow the CA to cure the hinge to the balsa.
