Well, materials aren't quite that limited. The complete list of materials is: wood, foam, paper, plastic film, carbon fiber, and/or glue. Any malleable, non-metallic material for ballast.
Note, the usual caveat applies, this is not the official rules site, clarifications or other. Check rules for yourself, and only go by official rules and clarifications.
And I'll add my sincere thanks to wisguy for getting the AMA Glider site back up, an invaluable resource.
