Yeah, Epoxy is just fine for doing what you want to do. Anything in moderation, meaning, only use what you need to use to do the job. You can also use a dab of Gorilla Glue with a spray of water. Watch it, and wipe any that may seep out as it expands.

But, I have the same plane, and assembled it using both foam safe CA and 5 minute epoxy.
