I agree with this post. I also seal the gaps both top and bottom and believe this adds strength to the hinge joint. I also have never had one fail from flight loads. Here is my last crash and the CA hinges didn't even fail in this. Notice all the controll surfaces.

I've had no trouble from quality ca hinges on gas birds. It also helps if you seal the gaps. Tends to spread out the stress. The only time I've had a CA hinge fail is when I've over stressed it(crashed![&o]). For the moment, fly it and check on your preflights. Replace if and when they fail.
