The only hinges I've ever had fail were Robarts. I had two shatter like glass on a Meister Corsair rudder. Drilled out the remains and installed two new ones with epoxy, which are still working now after many flights.
Never ever had a CA hinge fail. I have seen evidence of improper installation in failed CA hinge documentation. Usually they neglect to get CA wicked into each of the 4 contact surfaces. Some actually break the Tyvek cloth, by setting up the joint with zero gap between the control surface and the stationary surface - and then apply lots of travel, which stresses the cloth each time the control surface goes to extreme travel.
Looks to me like the common failure mode for CA hinges is breakage due to improper installation, while the common problem mode for any other hinge is binding - which doesn't necessarily break the hinge. People who try CA hinges can install them without much technique, no binding, and only have to make sure they drip CA into 4 locations per hinge, with the control surface deflected to its extreme position (away from the side being CA'd.)
If you're comfortable with Robarts, by all means use them.
Best wishes,

I finally got started on my Sig Somthin Extra!!
The last Kit I built was about 10 years ago and I used to use
Robart Pin hinges...

#307 or #309. I have never used a CA hinge and I am
a little leery of them. Am I way off base?
Thanks for the help
