ABSTRACT:
A remotely controlled model airplane includes a receiver responsive to signals from a transmitter to control the direction of flight of the model airplane. The receiver, powered by a battery, demodulates the signal transmitted by the transmitter to selectively energize an electrical coil to generate a magnetic field of a first or second polarity. A rudder pivotally attached to the vertical stabilizer includes a magnet responsive to the magnetic fields generated and is urged in one direction or the other resulting in commensurate pivotal movement of the rudder. A hinge interconnecting the rudder and vertical stabilizer urges return to center of the rudder after it has been deflected left or right by the magnet responding to the magnetic field created as a result of a signal transmitted by the transmitter. An electric motor also under control of the transmitter and receiver may be incorporated to rotate a propeller to provide thrust and forward motion of the model airplane. By employing a transmitter to selectively transmit a plurality of signals, control surfaces of the model airplane can be deflected to provide 2-axis control to selectively alter the direction and pitch of the model airplane.
