Shogun,

I believe the technique that you use to install CA hinges may be the reason for their longevity. I too leave a bigger hinge line gap and the stock CA hinges on all three of my UCD's are still holding up. Yes three (two 60's and one 46). I was expecting to have crashed a couple by now.

Anyway, I don't mind a larger gap because I have never seen a tight gap or sealed gap stop flutter or improve control surface authority. I've tried it.
