I have CA hinges on my Ultra Stick Lite. Hundreds of flights and no problems. Its powered by a G26, by the way. Perfect combo. My GP Christen Eagle, on the other hand, started breaking CA hinges after 3 flights.. I replaced them all with Robart Hinge Points. No more problems. I had CA hinges on my GP Giles too. Worked great. Finally sold the plane after a couple of years hard use. Hinges are still holding up.
