Ed, it sounds like you're putting a lot of effort into this project. We would all hate to see you bring your lovely creation home in pieces after it's first flight. To avoid this, here's what you need to do.

Go to your LHS (Local Hobby Shop) and ask where the local club(s) flys. Then go out there for a visit. Bring your plane with you. There are many things that can be overlooked in the building process that someone with a little more experience can see. You may not want to believe it, but you NEED the help these guys can give! Even if you are a full-scale pilot, chances are 99.8% that you will destroy your plane on the first flight without the help of an experienced R/C flier.

In regards to your hinge question: I also like the CA hinges. CA stands for cyanoacrylic (cyano- [like in cyanide]- Acrylic). It's what the world knows as crazy-glue, but in the R/C hobby, we use several types. The 3 most common are, thin, medium, and thick. I mention this because it is IMPERATIVE that you use THIN CA on the hinges. Crazy-glue is more like medium, so DO NOT USE CRAZY-GLUE from your local K-MArt. Go to the LHS. There you can get the hinges, the THIN CA, and the info on the nearest club.
