Except for the fuel storage, you could do it with just wood glue.

Make sure you coat the fuel storage really well with epoxy. I thought I was very careful with my fuel pump and fuel bottle, but on my third trip home with my new flight box, I pulled out the fuel bottle and looked in to see a good-sized puddle of fuel sloshing around.

Fortunately, I had coated it well and it drained out and cleaned up easily.
