Try thin plywood around 1/8 thick or balsa wood. It depends on what size boat you are building.

Just make sure the radio is on a ground frequency, not an aircraft frequency. Lite ply and balsa wood for a hull would work great.

Buy a 1/2" thick sheet of Dow blue foam, 4' x 8' for about 11 bucks. That will make several airboats, airplane floats, etc. I've made two airboats so far with it. I love working with it. It cuts cleanly with a band saw, lamiates quickly with 3M Super 77 spray adhesive (just don't overspray or it will melt the foam...lite coat sticks well), and I can shape it on my bench sander. You can glue on balsa covering and decking, or just coat it with 2-part bar epoxy or poly fiberglass resin, which is what I do. I epoxy glue in a square of 1/4" lite ply to attach my motor mounts to.
