What materials is Dragonfly made of?
The main structural materials are made of fiberglass and epoxy laid up over stryofoam blocks or sheets that have been carved or glued into the exact aerodynamic shape desired. Some wood is used for reinforcement of the fiberglass composite and for the firewall. Some metal is used where really heavy loads have to be attached, such as the wing and canard attachment points, the engine mount, etc. There is a small quantity of aluminum and steel tubing for the controls, angle and sheet metal, and so on.
