  • Patent number: 6022260
    Abstract: A model rocket kit which has a substantially lower material and manufacturing cost is provided. The model rocket kit includes at least one flat sheet of cardboard material which includes the outlines of the various components of a model rocket such as the rocket frame, nose cone, and recovery device. In order to assemble the model rocket, the various components are either punched by means of perforations or cut out of the flat sheet of cardboard material. The various components of the model rocket are then folded into the appropriate form and secured using conventional adhesive tape or the like. The resulting model rocket has a structurally stable and aerodynamic configuration which is reusable and results in a stable and true flight.
