Abstract: A toy paper airplane conversion kit has a nose-piece with a combination capacitor mounting portion and nose clip connected to a rear, electric motor driven propellor unit by a lead receiving, square section conductor conduit which keys into a complementary socket of the motor mount, maintaining the rear propellor unit tilted upward. The nose-piece has a combination capacitor mount and nose clip with two paper-clamping, cantilever spring arms extending rearwardly in spaced-apart, coplanar, side-by-side relation under the capacitor mounting portion and having converging portions adjacent rear free ends and, a stubby, paper spreading, crease stuffing fin from the nose-piece, rearward of free ends of the springs. The capacitor mouth receiving a charging plug of a battery pack unit.

Abstract: An inexpensive apparatus for powering a toy plane including a rubber band motor which is connectable to the plane's propeller and to a winding mechanism, including a gear mechanism which is activated by a handle. As the handle is repeatedly squeezed and released by the user, the motor is wound up. An anti-reversing ratchet is coupled with the motor to prevent unwinding until the user wishes to launch the plane.

Abstract: A launcher has programmable keys that activate a programming device to communicate with a flying toy to set up any one of multiple different motions of the toy. This is affected when the flying object and the launcher are connected together. Different combinations of program keys include changing of speed and landing procedures. The flying toy includes a receiver that operates a motor, and the flying object is clipped on the launcher and ejected after a user triggers the release button on the launcher.

Abstract: Disclosed is a method and system for providing an elastic drive mechanism in which the compressive force and torque created by the twisting of an elastic member used to power an aircraft are isolated from the fuselage, and specifically isolated from the flight control and aerodynamics surfaces of the aircraft. By isolating the elastic drive mechanism from traditional rearward fixed contact points on the fuselage, the detrimental consequences of these elastic forces are eliminated producing longer, farther and more controlled flights.

Abstract: A model airplane includes a main body component, a wing component, a horizontal stabilizer component, and a vertical stabilizer component. At least some of the components are fabricated of a shell of lightweight wood with spaces therebetween. A sheet of lightweight plastic material covers each of the components. The material is wrapped around the components with an individual sheet for the components. The plastic material is lightweight with a thickness of between about 0.65 and 0.85 mils and has the ability when heated to contract to about 25 percent of its original size.

Abstract: The present invention relates to a model glider having twin propellers, which includes a central frame which forms a body of the glider, a vertical tail and a pair of horizontal tails respectively provided on the rear part of the body, a pair of main wings horizontally provided on the middle part of the body, a rotating member, a power transmitting part, an elastic band member, a stopper, a driving part to rotate the twin propellers, and a link lever, wherein the elastic band member is elastically twisted by the rotation of the link lever and while the elastic band member is restored, its rotary power is transmitted to the propellers via the transmitting part and the driving part, so that the model glider has strong propulsive force by means of the twin propellers to increase gliding distance and user' interest.

Abstract: A toy airplane and launcher assembly comprises a rubber band powered toy airplane having a propeller at its front end, a winding coupler disposed at its rear end, and a pair longitudinally aligned sleeves mounted to its belly. A rubber band extends between the propeller shaft and the winding coupler shaft. A pistol-shaped launcher includes a handle and with an elongated guide rod extending therefrom. The guide rod is sized to be received through the aligned sleeves of the airplane to mount the plane on the launcher and a latch releasable latches the plane in place when the guide rod is fully received through the sleeves. A coil spring extends about the guide rod and is progressively compressed as the plane is mounted on the launcher to catapult the plane from the launcher when the latch is released.

Abstract: A device for winding a rubber band motor has a very light weight so that it may be carried by a model airplane, almost without any weight penalty. A pulley with a recoil spring has a string wound thereon so that the release of a pulled string rewinds it onto the pulley. A clutch mechanism engages the pulley and rubber band when the string is pulled and disengages when the string rewinds. This way, the string may be pulled repeatedly in order to store more energy in the rubber band.

Abstract: A model spaceship having a tubular propulsion duct (1) with fan (25) to which a circular wing (2) is attached at a top-forward position and pod wings (3,4) positioned at each opposite top-side position. The circular wing (2) is supported by a forward strut (8) extended forwardly and upwardly from a top-front portion of the propulsion duct (1). Each pod wing (3,4) is supported by side struts (5,6) extended sidewardly and upwardly from an intermediate portion of the propulsion duct (1). The pod wings (3,4) are joined by a horizontal wing (7) that provides lift and horizontal stabilization. Contour of the circular wing (2), the pod wings (3,4), the side struts (5,6) and the horizontal wing (7) all provide lift. Lateral attitude control is provided by ailerons (15) on the pod wings (3,4). An elevator flap (18) for horizontal attitude control is positioned on an aft edge of the horizontal stabilizer wing (7). A model-airplane motor (24) provides rotation of the duct fan (25) for propulsion.

Abstract: A toy airplane launcher apparatus includes a toy airplane having an electric or rubberband motor for rotating a prop which is rotatably mounted to the airplane. The launcher includes a guide rail which slidably carries a rear launcher section which is slidable into engagement with a front launcher section engaged to the front end of the guide rail. Two rubberbands are engaged between the front and rear launcher sections to hold them together and for biasing the rear launcher section toward the front launcher section when the two are separated from each other. The rear launcher section is engageable with the trigger and is either fixed to or detachably engaged with the airplane. When the trigger is moved, the rear launcher section moves quickly along the rail into engagement with the front launcher section. If the rear launcher section is fixed to the airplane, both front and rear launcher sections leave the rail and are launched along with the airplane.

Abstract: A flying model airplane which has a triangular shaped fuselage (20) with a wing (34) attached through a combination of an attaching eye (28) passing through a wing interlocking member (38) held in place by a landing gear wire strut (54). A tail is similarly attached with a body dovetail fastener (32) penetrating a tail attaching plate (46) through which a stabilizer projecting finger (50) is positioned. The wing is further supported by a pair of tendons (40) attached to the fuselage through a hook (26) on one end and a wing supporting hook (36) on the other. The model is assembled or dissembled repeatively heretofore unavailable.

Abstract: Disclosed is model flying vehicle wherein the main wing returns from the slanting position (that is, with a proper elevation angle) to the flat position when the power is disengaged, thereby ensuring stable and smooth landing without impact or damage to the flying body or the wing.
