Abstract: A radio-controlled model airplane, including: a fuselage; first and second wings connected to the fuselage; and a control system including: a battery; a receiver powered by the battery and arranged to receive radio frequency signals; and a computer powered by the battery, electrically connected to the receiver, and arranged to transmit control signals in response to the received radio frequency signals. The airplane also includes a first motor powered by the battery and arranged to receive the transmitted control signals to rotate a propeller; and a single flexible wire: passing through an opening in a distal end of the first wing; with a first end fixed to a point at or near a junction of the first wing and the fuselage; and with a second end for connection to a point outside of the model airplane.

Abstract: A tether assembly for a radio-controlled model aircraft, including: a bracket arranged for fixed connection to the radio-controlled model aircraft and including a stop portion; and a bar with a first end pivotably connected to the bracket, and a second end arranged to connect to a flexible wire for a model aircraft anchoring system. Pivoting of the bar in a first rotational direction with respect to the bracket is limited by contact of the bar with the stop portion.

Abstract: A propulsion system for miniature vehicles, such as model airplanes, having multiple direct-current motors arranged about a central axis of the propulsion system in a radial, opposed, in-line, or V-12 configuration. The motors drive a propeller system.

Abstract: The invention relates to a remote control flying machine, in particular a remote control ultralight helicopter, with at least one rotor blade (104), the pitch (&agr;) of which may be adjusted. According to the invention, the adjustment of the pitch (&agr;) of the at least one rotor blade is achieved by means of a force, in particular a torsion force directly applied to the rotation axis of the rotor blade. Said force is generated by a magnetic field, variable by the electrical control of at least one coil (196) which is not part of an electric motor.

Abstract: A fishing lure to simulate a dragonfly in a hovering orientation above a body of water is presented to effect luring of various game fish. The dragonfly member is defined by an elongate body mounting a plurality of cluster hooks at spaced intervals along the bottom surface thereof. The dragonfly structure may be mounted in a suspended orientation relative to the body of water utilizing a flotation device, or alternatively utilizing a drive motor and associated receiver and transmitter to effect hovering orientation of the lure. Further, the lure may be formed with a concave nose and a container within the body to effect selective tippage and repositioning of the body during its displacement through the body of water.

Abstract: An engine-spiraled, stabilized toy football including a skeleton made up of a plurality of spaced ribs collectively configured as a truncated football. An external skin of strong, thin plastic covers the skeleton. A generally conical zone at each end of the football is not covered by the skin. The circular opening thus formed at one end accommodates an air intake pod. An engine mounting tube is disposed centrally on the interior of the football and is secured to the skeleton of the ball and opens out of the opposite end of the ball from the air intake pod. An engine is secured in the engine mounting tube and drives a propeller housed within a gyroscopic propeller ring. The propeller and gyroscopic ring turn freely within the skeleton and skin, and function to pull air through the air intake pod and force the air out the open end of the engine mounting tube at the opposite end of the ball. A system is provided within the ball for starting and fueling the engine.

Abstract: A remote control lighter-than-air toy apparatus has an inflatable container having a predetermined shape, such as the shape of a dirigible, for holding a lighter-than-air gas. A gondola is removably attached to the inflatable container and has a shaft extending therethrough and rotably supported thereon. A reversible electric motor is attached to each end portion of the shaft passing through the gondola with each electric motor having a propeller attached thereto for rotation upon actuation of the electric motor. Each of the electric motors and propellers are fixedly attached to the shaft. A tether line is formed of a plurality of conductors, each connected at one end to one of the electric motors and connected at the other end to a control box having a plurality of controls thereon for remotely controlling each motor separately, so that a lighter than air toy can be remotely controlled with two propellers.
