I'm surprised Minn didn't post a link to his article on installing CA hinges:

What kind of CA are you using? You should be using the thin kind. If you can see it on the hinge, it sounds like either too much or it's too thick.
Edit: I forgot to ask, what size hinges are you using? They do make small sizes for smaller planes.
