Among other things, a game includes individual game pieces and an airborne vehicle (having a motor, a battery connected to the motor, a propulsion device connected to the motor, and a game piece support). A controller is configured to activate the motor when a first period of time has passed after one of the individual game pieces has been received at the game piece support and to deactivate the motor when a second period of time has passed after the motor has been activated.

A monitoring terminal includes a transceiver, a receiver, and a processor. The transceiver provides a two-way communication with an unmanned aerial vehicle (UAV) via a first communication link and is configured to receive feedback data and a feedback data indication from the UAV and transmit control data to the UAV. The receiver is configured to receive the control data and a control data indication 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 based on the feedback data indication and the control data indication.

Flight control method and apparatus for multi-rotor aircraft that is programmed for varied control commands and conditions in the control of the aircraft in flight.

A toy system having a folding kite projectile and a launcher that launches the kite projectile into flight. The kite projectile is launched in a folded configuration. Once in flight, the kite projectile expands into an open configuration. The kite is biased into its open configuration by an internal spring bias. The kite projectile is manually manipulated into its folded configuration prior to launching. The transformation of the kite projectile its folded configuration to its open configuration is delayed by an internal deployment control that opposes the spring bias and delays movement of kite projectile components that expand after launch. In this manner, the kite projectile cn fly in its folded condition for a period before it opens. This maximizes the distance the kite projectile travels by the force of the launcher.

A propulsion system for a vehicle or toy vehicle is disclosed. The system comprises rotary drive means for driving the vehicle along ground, the rotary drive means operating in a plane and having a peripheral ground-engagement part. The system further comprises a rotor comprising one or more rotor blades rotatable about a rotor axis for producing thrust, wherein the rotary drive means and the rotor are positioned relative to each other so that during rotation of the rotor, the rotor blades pass through the plane of the rotary drive means, inside the peripheral ground-engagement part. In this way, the rotor blades are protected by the peripheral ground-engagement part.

A disk-like toy includes a resilient base, a flexible cover overlying the base, and a deflectable core disposed generally between the base and the cover. The base is affixed to at least one of the cover and the core.

A pitching arrangement for a model helicopter includes a securing base, a plurality of servers supported by the securing base, a main connecting shaft linked to the servers, a supporting ring, a control device operatively provided between the servers and axially mounted to the main connecting shaft, and a plurality of connecting rods connecting the servers and the control device through the main connecting shaft, wherein the supporting ring is mounted on the main connecting shaft, wherein the connecting rods are connected to the supporting ring of the main connecting shaft.

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.

There is provided a transmitter for facilitating control of a flying object including an elevation control lever 22 for controlling a flight height of a helicopter 1, a cover 24 through which the elevation control lever 22 passes via an opening 26, a step 27 formed on an edge of the opening 26, and a rotation member 28, which rotates, disposed to a backside of the cover 24, where apart of the cover 24 is formed into a curved surface which overlaps a curved surface of the rotation member 28, and rotational speeds of motors 11, 12 internally mounted on the helicopter 1 are set corresponding to the step 27.

A throwing or catching toy includes a generally elongated spheroidal body defined as having a longitudinal axis, where a length of the body along the longitudinal axis between a front end to a back end of the body is longer than an equatorial diameter. A support is attached to the body and extends beyond the back end of the body and does not extend beyond the front end of the body. A lift-generating wing is non-movably attached to the support. A push surface is disposed near the back end of the body, where the push surface is generally perpendicular to the longitudinal axis. A horizontal stabilizer is attached to the support and disposed behind the lift-generating wing. An impact transfer surface is attached directly to the support, where the impact transfer surface is disposed within the body and fixed between the front end of the body and the support.
