Materials

You will need a Delta Dart kit (sometimes called the AMA Cub), which includes balsa wood, tissue paper, and the propeller assembly. You will also need a razor blade to cut with, straight pins for support during construction, and glue for the actual assembly.
 
You will also need a building board, larger than the piece of tissue paper (which is roughly 8.5" by 14") and which you can stick pins into.
