I've "pinned" CA hinges with toothpick sections pushed up from the lower (less visible) side in pre-drilled 1/16" holes. Back in my real belt-and-suspender days. I have come to trust CA hinges since and don't bother. My 14 lb G.P. Ultimate 43cc has CA hinges throughout (as do all but one of my models - that one has brass pinned Nylon hinges). I just take a lot of care in installing them and yank on the control surfaces as a pre-flight to make sure they're sound. Bennett Built sells 1/4 scale CA hinges and that is a good endorsement. As Da Rock said: I won't use a CA hinge that's not fuzzy.

And I follow Minn Flyers' tips - pin to center and pre-drill a hole in the slots to encourage CA flow.

I cut a bunch of fitting dummy hinges out of a milk bottle so I don't "wear out" the CA hinges during the building and trial fitting process. I think that may happen with over-handling when test fitting and using the hinges themselves to work the slots open. I use a hacksaw blade sharpened on the ends for that.
