I've used CA hinges on over 30 planes I've built for myself, and others. I havent had one fail yet. I actually prefer them over the Dubro hinges. They are much easier to use, you dont need to worry about aligning them, and they hold glue very well. Just stick them in the slot, and run a few drops of CA on them, Presto! They dont get brittle, and they actually hold stronger and longer than Dubro hinges. I would recommend them for any planes .25-1.80 size. Monokote hinges work best for small planes.

Good Luck!
