Most CA hinges are good hinges. I've never seen a failure from the ones that have that fiber coating on both sides. The only ones I've seen fail were ones in models that came already hinged and that had the slick, cheap hinges. There are a number of "great value" ARFs that come with what looks like reclaimed scrap plastic for their pre-hinged hinges. We had one of those shed an aileron about two days ago. It actually didn't shed it, just lost all three hinges and the flutter made the sucker uncontrollable. BIG MESS. Might have ruined the engine.

There have been posts in the past that told of using the plastic in the media taken from old floppies. Seems it flexes ok and will bond to balsa with CA. I cracked open an old floppy and the plastic looks very much like what I've seen used in the prehinged hinges.

I'm just now starting my new Skybolt ARF and it comes with CA hinge material. The stuff looks excellent. I'm debating using it because it feels like it'd be flexible enough and looks bulletproof. When you have the chance to choose your own hinges, there's nothing wrong with good CA ones. And I've never seen obviously good ones fail.
