While the Wright Brothers are credited with making man's first controlled powered flight, one of their most significant contributions to flight was inventing the modern airplane propeller. Now you can own your own hardwood hand-propelled aircraft patterned after the propeller that powered the Wright Flyer. The Puddle Jumper can soar up to 50 feet. Made of wood and stained in primary colors. Instructions included. Colors of propeller vary and cannot be specified.
