Default RE: Need CA Hinge Help

One suggestion was to first glue the hinges into the control surface and later glue the other half of the hinges into the airplane
NO! If you glue half the hinge into one surface, the CA will wick into the other half of the hinge. You can't stop it. And once the hinge has absorbed CA it won't absorb more later.

As I mentioned earlier, you do not have to drill holes when using this type of hinge (with the slot). I've used many types of CA hinges, plastic hinges without pins, that have to be epoxied in, the "Robart type" hinge points that I believe Istool and Balsa Master were referring too, as well as about any other hinge out there.

CA hinges are great for most sport type aircraft in the 40 to 60 range, and even slow flying planes like Cubs in larger sizes. CA hinges allow for easy installation and tight (no gap) control surfaces. There is nothing wrong with them if installed correctly. (And installation is simple.)

I prefer hinge points for larger and/or faster aircraft. I don't like most flat plastic hinges though.

You'll be fine with the CA hinges. If installed as in Minn's article they'll work great and last longer than your plane.
