An aircraft control system and control method are disclosed. The system comprises a remote control apparatus with a first control rod and a flight controller associated with an aircraft. The first control rod is configured to move in a first movement direction to control a motion of the aircraft in a first motion direction when an external force is applied on the first control rod and after a withdrawal of the external force, the first control rod returns to a preset position. The remote control apparatus operates to generate one or more control signals corresponding to the withdrawal of the external force. The flight controller controls the aircraft to maintain a flight state based on said control signals and one or more state signals, which are generated based on a measurement of the flight state by a flight controller associated with the aircraft state measurement sensors carried by the aircraft.

A radio controlled (RC) vehicle includes a receiver configured to receive a radio frequency (RF) signal from a remote control device. The RF signal indicates command data in accordance with a first coordinate system. The command data includes yaw-velocity command data. The RC vehicle includes motion sensors configured to generate motion data. The RC vehicle includes a processor coupled to the motion sensors and to the receiver. The processor is configured to transform the command data into control data based on the motion data and in accordance with a second coordinate system from a perspective of the RC vehicle. The control data includes yaw-velocity control data. The yaw-velocity control data is related to the yaw-velocity command data. The RC vehicle includes control devices coupled to the processor and configured to control motion of the RC vehicle based on the control data.

Methods and systems for utilizing a mobile computing device (e.g., such as a mobile phone) for use in controlling a model vehicle are described. Consistent with some embodiments, a mobile computing device provides various user controls for generating signals that are communicated to a radio transmitter device coupled with the mobile computing device, and ultimately broadcast to a receiver residing at a model vehicle. With some embodiments, the mobile computing device may be integrated with a controller housing which provides separate user controls, such that a combination of user controls present on the mobile computing device and the controller housing can be used to control a model vehicle.

An aerial vehicle includes an aerial vehicle body, and first and second rotor assemblies. The first rotor assembly includes a first hub coupled to first blades, and a first drive shaft coupled to the first hub via fastening features. The first drive shaft is configured to rotate the first hub in a first direction such that the first blades rotate in a first rotation plane. The second rotor assembly includes a second hub coupled to second blades, and a second drive shaft coupled to the second hub via fastening features. The second drive shaft is configured to rotate the second hub in a second direction opposite to the first direction, such that the second blades rotate in a second rotation plane. The first and second rotation planes are at opposite sides of the aerial vehicle body.

Control of a toy flying toy plane comprises providing the plane having a motor and propeller and a separate remote controller for use by a player of the toy. The plane includes a flexible, foldable wing and a fuselage below the wing. The fuselage supports at least one propulsion unit and the fuselage is removably locatable relative to the wing. A signal is sent from a transmitter with the toy to the controller. A variation in intensity of the received signal to the toy being from the controller. The controller transmits a signal to the toy according to the desired action of the player and thereby to cause the flying toy to move as required.

An unmanned aerial vehicle (UAV) includes a propeller, a driving device, and an elastic abutting member sleeve. The propeller includes a blade base, a blade mounted on the blade base, and a first installation foolproof member disposed on the blade base. The driving device includes a main body, a driving shaft rotatable relative to the main body, a locking member disposed on the main body, and a second installation foolproof member disposed on the locking member. The driving device is coupled with the propeller. The elastic abutting member is coupled with the driving shaft and disposed between the main body and the blade base and abuts against the main body and the blade base.

A hinged component fabrication method in which, in a layup stage of fabrication, the component includes a live hinge joining uncured material portions together at a hinge region and comprising a layer of tensile fabric at least partially infiltrated by an uncured elastomer layer at least partially interposed between the tensile fabric and the uncured material portions such that the uncured elastomer blocks the uncured material portions from infiltrating the hinge region. The method may include locating overlapped tensile fabric and elastomer layers in a tool and introducing polymer-based material into the tool such that polymer-based material portions overlap respective opposite ends of the fabric and elastomer layers. The polymer-based material portions are formed to a desired shape using the forming tool so that the fabric and elastomer layers form a live hinge between the polymer-based material portions.

A device includes a transceiver, a receiver, and a processor. The transceiver is configured to receive feedback data from an unmanned aerial vehicle (UAV) and transmit control data to the UAV via a first communication link. The receiver is configured to receive the control data from a controlling terminal via a second communication link. The second communication link does not interfere with the first communication link. The processor is configured to determine whether the feedback data and the control data are being simultaneously transmitted via the first communication link.

The present invention relates to a book comprising a first outer cover having a substantially planar body defining a first aperture extending therethrough; a second outer cover having a substantially planar body defining a second aperture extending therethrough; and at least one inner element located between the first and second outer covers, the or each inner element having a substantially planar body defining an inner element aperture extending therethrough; wherein at least a portion of the first and second apertures and the or each inner element aperture are aligned with one another to define a receiving aperture extending through the book.
