Dave, you've got to be doing something wrong! That's just too many broken hinges. There are a lot of people using CA hinges with no problems.

Many pattern fliers use CA hinges on 2 meter pattern planes and put literally thousands of flights on them without any troubles.

I know that pattern planes don't use extreme throws on all control surfaces but they do use pretty large throws on the rudder. There's just got to be something wrong with the way your installing them.

Why don't you describe exactly how you installed them and maybe someone will pickup on your error. I remember a thread a while back where some guy had similar problems and he didn't realize that you were supposed to insert them before putting the CA on them. I think he was putting medium CA on them and then sliding them in. I'm not suggesting that you're doing this, but there must be some detail of what you're doing that's causing your problem.

Also, if you describe your approach include what type of CA you're using, what brand, and how old it is. This sometimes makes a big difference.

Best of luck,
Keith
