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.

An airplane, which includes an airframe and a full-segregated thrust hybrid propulsion system mounted on the airframe. The propulsion system includes: one or more sustainer thrust producers; a plurality of electrically powered thrust producers disposed in predetermined positions as a means for providing additional thrust to the airplane, and to supplement airflow over the wings, flaps, and roll control devices of said airplane; whereby increasing the lift of the wing surfaces and providing enhanced control in the roll axis. The trust producers operate independently from one another, with no aerodynamic, electrical or mechanical inter-connection. Safety is enhanced by the ability of either the sustainer thrust producer(s), or the electrically powered augmentation thrust producers to sustain flight to a suitable landing area, should the other system fail.

A motor assembly that includes a motor having a motor casing, a rotatable shaft extending from said motor casing to a shaft length and a hub coupled to said rotatable shaft, the hub having a circumferential skid surface disposed immediately proximal to the motor casing and having a channel configured to seat a propeller, when a propeller is present, wherein a bending moment applied to the shaft through the hub results in the circumferential skid surface contacting said motor casing.

A vehicle control system may include a vehicle frame, a mount secured to the vehicle frame and configured for rigidly securing a smartphone therein such that motions experienced by the vehicle frame are correspondingly experienced by the smartphone, and system electronics arranged on the frame and in communication with the smartphone and vehicle controllers, the system electronics configured to receive signals from the smartphone and control directional devices of the vehicle based on the signals via the vehicle controllers. A system for preparing signals for transmission to the vehicle to control navigation may also be provided.

Locking device, propeller, and aerial vehicle are provided. An exemplary propeller includes a blade; and a locking part, configured for locking the blade to a driving shaft. The locking part includes a fastening portion and a pressing portion. The pressing portion includes a pressing end, an abutting end including an accommodating hole, and an abutting part configured within the accommodating hole for abutting against the fastening portion. The fastening portion is accommodable within the accommodating hole of the pressing portion. The pressing portion of the locking part is slidably connected with the blade. A portion of the driving shaft protrudes into the accommodating hole of the pressing portion. The fastening portion is abutted against the abutting part of the pressing portion and engaged with the driving shaft to lock the driving shaft on the blade.

An angle detecting device includes a rotatably supported magnet, and a magnetic sensor disposed opposite to the magnet. An output of the magnetic sensor is changed based on a magnetic flux change due to a rotation of the magnet. The magnet is disposed such that a distance between the magnetic sensor and the magnet is changed by the rotation of the magnet.

A method for beautifying a balsa wood model aircraft with a thermal shrink covering film, so that the balsa wood model aircraft with a thermal shrink covering film is obtained. This method makes a model aircraft colorful, reduces labor costs, improves the beautifying and painting effect of the model aircraft, and also improves the pneumatic performance of the model aircraft.

The invention relates to a method for covering light aircraft and/or parts thereof with a polyester covering fabric, and to a dispersion hot-melt adhesive and to the use thereof for covering. The invention further relates to a light aircraft or to a part of the same which is covered with a polyester covering fabric by means of the method according to the invention.

Embodiments of the present invention discloses a wing detachment assembly and an aerial vehicle. The wing detachment assembly includes a first connecting portion and a second connecting portion, one of the first connecting portion and the second connecting portion being fixed on a wing and the other being fixed on a vehicle body. The second connecting portion includes a thumb wheel, the thumb wheel being provided with a threaded hole and being rotatably mounted on the vehicle body or the wing. The first connecting portion is threadedly connected to a threaded hole of the thumb wheel, the first connecting portion and the thumb wheel being fastened or detached when the thumb wheel is rotated. The aerial vehicle includes the foregoing wing detachment assembly. The wing detachment assembly and the aerial vehicle have the advantage of being convenient to detach and mount the wing.

A model vehicle with body mount components are provided. A tongue member attached to a model vehicle body with a first and second tongue member is configured to engage a first securing member attached to a model vehicle chassis. A top surface of the second tongue member draws the model vehicle body towards the model vehicle chassis when the second tongue member engages the first securing member. A lever member with a lever handle, jaw clamp, and a lever pivot is configured to pivot between an engage and an unengaged position. The jaw clamp engages with a second securing member in the engaged position. The lever member further contains a retaining mechanism that is configured to rotate between a retained and unretained position. The retaining mechanism inhibits the lever handle from moving from the engaged to the unengaged position when the retaining mechanism is in the retained position.
