Abstract: An unmanned aerial vehicle includes a fuselage, a motor mounted at the fuselage, and a control apparatus configured to control the motor. The control apparatus includes one or more processors configured to obtain a present electrical parameter of a battery configured to power the motor, calculate a compensation amount of a control signal of the motor according to the present electrical parameter, and modify the control signal according to the compensation amount.

Abstract: A remote controlled aircraft includes an aircraft that may be flown. A plurality of light emitters is coupled to the aircraft. A plurality of fans is coupled to the aircraft. Each of the fans may move air thereby facilitating each of the fans to urge the aircraft to fly. A control unit is coupled to the aircraft and the control unit is electrically coupled to each of the fans. The control unit includes a global positioning system. Thus, the control unit may identify a position of the aircraft with respect to Earth. A remote control is provided and the remote control may be manipulated. The remote control is in electrical communication with the control unit such that the remote control controls directional flight of the aircraft.

Abstract: The present invention 10 discloses a model aircraft 14 for preventing the fouling of control lines for tethered aircraft controlled by means of radio frequency transmission 12. The present invention 10 has a coupling 22 for model aircraft attached by a semi rigid conduit 20 to a base control unit 18. The rigid conduit 20 is a composite material tube providing anti-sway control. The tube 20 houses a lubricant and drive cable 40 connected to a coupling 22 connecting the aircraft 14 to the base control unit 18 whereby various aircraft may be substituted. At the other distal end the semi-rigid member is removably secured to a drive module housing the drive motor 36 that forms part of the base control unit 18. The base module 18 houses a power supply 52, receiver 48, servo motor 50 and speed control 46. A hand held remote control 12 unit is used to transmit control signals for the aircraft elevator control and prop speed.

Abstract: A toy airplane game involving a central upright member, flying device, airplane tether mechanism attached to the flying device, and landing area, wherein the operator controls the operation of the flying device in takeoff, flying and landing to different predetermined location on a map or the like.

Abstract: A toy game consists of a map hung beneath a ceiling or a pole, a model aircraft suspended from a map by flexible, plastic string, and a double remote control--one for flight control and another for altitude control. It is operated indoors or outdoors. The aircraft maneuvers including take-off, climb, descent, and landing are controlled by operators. The system consists of tracks in hanger going along the border of the map of the United States of America, an upper motor, a lower motor in fuselage of aircraft, wheels, wired-plastic string, a battery box, bulbs, electric wires and cables. The upper motor is used for propelling to simulate an aircraft flight with all features along border for locating states and cities. The lower motor is used to make altitude changes. The purpose of AIRPLANE FLYING GAME is to help memorizing the location of states and cities. It is an entertainment game but an educational toy as well.
