I've not tried those hinges yet, Opjose. They look like you really have to be careful with alignment, but look pretty reliable, once installed.

Every glow plane that I own have CA hinges. The best advice I can offer for new installations is to CA once on each side. Apply your three or four drops of CA on each side then do NOT re-apply. All mine are intact and secure.

For the Original Poster, for repairs, you should cut the aileron away, and do exactly like Opjose suggests, carefully trim the old CA hinges flat to the surface, sand it a bit, and re-slot fo rnew CA hinges near the original slots or use those hinges Opjose has suggested. Either way, do not fly that plane with the broken hinge. It will put more stress on the other ones and they can and may tear apart on you.
