Materials

You will need the Raven kit, which includes balsa wood, rubber bands, and the propeller assembly. You will also need a razor blade to cut with, straight pins, a pencil or pen for marking, scissors, and ordinary white glue for the actual assembly. (Though super glue comes in handy for field repairs!)
 
You will also need a building board, larger than the pieces laid out. And you can use the plastic bag in which the kit came as a non-stick gluing surface.
