ABSTRACT:
An electrically powered tethered model airplane connected to a central post or pylon. The tether line is also the electrical wire to supply power to an electric motor in the airplane that drives the propeller. The airplane assembly typically has two airplanes connected to the central pylon. A unique connection arrangement at the interface of the tether lines and the central pylon allows not only for electrical contact, but also for circular movement of the tether lines and planes around the pylon without becoming wrapped or wound on the pylon. Two transformers are connected to the electrical connection at the top of the pylon, enabling two operators to control their respective airplanes for various maneuvers.
