Thanks for asking the question and starting this thread. Glad I saw it.
I just cut the slots for the aileron hinges on a Balsa Nova ARF, and was going to do the epoxy thing today. I agree with what everyone in here has said about epoxy....I just never thought "outside the box" about this. I've never heard of Pacer Hinge Glue. What is it and where do you get it? Sounds like Titebond is a good way to go. Also, here's something I've been doing since I had a scary "flutter" problem on a fast pattern plane. I use very small flathead woodscrews to "pin" the flat hinges. Drill from the bottom of the wing and aileron up thru the hinge, but don't penetrate thru the upper surface. This way, nothing shows from the top view of your plane. Put a little clear GE Silicon glue/sealant on the screws so they won't turn loose under vibration. The Silicon glue lets you remove the screws if you ever need to do this. The small flathead screws are put in so they are flush with the surface on the underside of the wing trailing edge and aileron. Makes for very secure hinges.
