In my opinion, what is really wrong is using CA hinges to start with... though I'm really not wishing to sound contrary.

I used them on one model, an Ultra Stick Lite and two weeks ago fortunately noted when they failed so prevented a possible mishap. I'd started the engine and luckily noted some strange rudder movement when picking it up to carry to the flight line. Two of three hinges were broke. If the third had broken and the control wires had held a flailing rudder, it might have gotten dicey.

Failure came at thirty six hours of operation. The effort needed to replace the hinges and the ruined day of flying were not worth the effort savings of their simpler installation.
