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.

A radio controlled (RC) vehicle includes a receiver that is coupled to receive an RF signal from a remote control device, the RF signal containing command data in accordance with a first coordinate system, wherein the first coordinate system is from a perspective of the remote control device. A motion sensing module generates motion data based on the motion of the RC vehicle. A processing module transforms the command data into control data in accordance with a second coordinate system, wherein the second coordinate system is from a perspective of the RC vehicle. A plurality of control devices control the motion of the RC vehicle based on the control data.

A remote control vehicle comprises light fixtures, which when operated at high speeds, can create a neon glow in its wake. The remote control vehicle has at least eight distinct color combinations, can spin and flip in three hundred sixty degree stunts, and travel through all terrains. A remote control is responsible for remotely communicating aspects related to the control of the remote control vehicle, such as speed and drifting.

Water reveal objects and methods of making and using same are described. In some embodiments, the objects are three-dimensional objects (e.g., animals, figurines or toy models) that are assembled by the user from a variety of pieces. The pieces may be comprised of multiple layers, such as a base layer, a film that includes one or more designs covering the base layer and a water-reactive coating that hides the one or more designs when the coating is dry and reveals the one or more designs when the user brushes water on the coating. The coating and film may be on one or multiple sides of the pieces. The pieces may be provided to the user in a sheet that is partially precut to facilitate removal of the pieces. In other embodiments, the present disclosure provides a sheet or roll of stickers.

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.

In one embodiment there is provided a flying toy that can be manually pumped with air. The pressurized air is kept in a canister and use to drive a propeller to propeller the toy for flight.

The subject matter of this specification can be embodied in, among other things, a modular vehicle that includes a vehicle body defining a seat space that is at least partially enclosed and defines an interior volume to contain one or more character figures, a first character seat assembly removably mountable to the vehicle body within the seat space as a first simulated seat, and a second character seat assembly removably mountable to the vehicle body within the seat space as a second simulated seat that is sized differently from the first simulated seat such that the second character seat assembly is prevented from removably mounting to the vehicle body within the seat space when the first character seat assembly is removably mounted to the vehicle body within the seat space.

An objective of the present invention is to eliminate unnatural behaviors of a wireless controlled airplane during PID control. In a wireless controlled airplane, a receiving section receives a first operation signal for a first actuator, a second operation signal for a second actuator, and a third operation signal for a third actuator, wherein the first, second and third operation signals are provided as operation signals wirelessly transmitted. A first actuator control section is configured to generate an actuation signal for the first actuator by means of PID control depending on the first operation signal, and to reduce an integral element in the PID control depending on an operation value for the second or third operation signal. Alternatively, the first actuator control section is configured to perform switching to a control without an integral element from the PID control.

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.
