  • High performance rubberband launched toy autogiro with fold out wings
    Patent number: 6247990
    Abstract: A new high performance rubberband launched toy autogiro is described. Using lightweight rigid materials, this device ascends at high velocity to over 100 feet, then unfolds its wings and begins a spinning slow-speed descent lasting 15 seconds or more. Minimal skill is needed to launch this toy, and depending on the force used to launch it, short or long times aloft can be achieved. Under thermal updraft conditions, descent time can extend to over a minute.
