Well, agexpert, you and I couldn't be farther apart on this subject. You know what you know and I know what I know. Anythng I post in here I've either done or seen done successfully. Your mileage may vary.

I, personally, have installed CA hinges on pylon racers, a giant scale Stinger, and Unlimited-class competition fun fly planes. That's about as extreme as you can get. BTW, Unlimited-class competition fun fly was what 3D was before people knew to call it 3D. When you're doing 3' diameter loops 4' off the ground at full throttle, that's extreme. This is on a 48" wingspan plane with 5" wide ailerons and a 4" wide elevator. A .32 engine typically turning a 10-4 prop at over 15 grand.

Minnflyer makes some good factual points. If you make the hinge line gap too tight, you'll stress the hinge. If you do any of the other no-nos other posters, including myself, have mentioned, THEN they will fail.

I don't fly lazy circles. I have a self-designed Miss Martha-type that'll run about 100 mph and will cut its own tail off in maneuvers. All at full throttle. 3 turn per second rolls and a vertical rolling full throttle Death Dive that ends with a square corner pull out. That's extreme.

I'll repeat and stand by it - if your CA hinges are failing, they're not installed properly.

And on that note, I'm outta this one.
