The present invention is a radio-controlled (RC) model aircraft system with laser tag capabilities. A transmitter and receiver are each installed in at least two separate RC aircrafts. The transmitter on one aircraft emits an infrared light beam to the receiver on the other aircraft(s) that changes the infrared signal to a first servo to move an arm, which releases a model aircraft door behind which there are ribbons. The ribbons escape from the aircraft wings to show a hit. An optional second servo operate a smoke screen and eject a pilot to simulate actual combat. The system may also include audio and lighting effects to simulate firing and hit sequences with accompanying theatrical, physical effects including release of smoke and ribbons, and ejection of the pilot that realistically simulates air combat.

The invention relates to an autonomous return system and a control method of a dual-rotor remote-controlled model helicopter, belonging to the technical field of autonomous return of a remote-controlled model (unmanned) helicopter. The system comprises an airborne part and a ground control station part; the airborne part comprises a main rotor motor, a tail rotor motor, a single-polarity PWM (pulse-width modulation) output drive circuit, an H-bridge direct current motor drive circuit, a micro controller, an MEMS (micro-electromechanical system) single-axis gyroscope, an MEMS dual-axis gyroscope, an MEMS tri-axis accelerometer, a signal conditioning circuit, a resetting circuit, a small voltage difference linear voltage stabilizer, a JTAG (joint test action group) interface, a wireless data transmission module and a power supply, and the ground control station part is formed by sequentially connecting a ground station computer and a ground wireless data transmission module. According to the autonomous return system and the control method, the model helicopter can autonomously return to the remote-controlled range after the model helicopter flies off the remote-controlled range, and the stability of flight of the helicopter can be improved.

A control method and device for motion mode of a remote control model and a remote control model. The method includes: in case that a control mode in pre-configured multiple control modes is triggered, an instruction set corresponding to the triggered control mode is called according to the correspondence between the scheduled control modes and the instruction sets, wherein each instruction set is used to control the remote control model to move in case that the remote control model meets the requirements of the corresponding control mode; according to the instructions in the called instruction set, the movement of the remote control model is controlled. By configuring of the multiple control modes and the corresponding instruction sets, the remote control model can be controlled automatically in case that a specific control mode is triggered, thereby preventing the problems that the model is damaged or lost caused by user misoperation, effectively reducing the difficulty of remotely controlling the model and promoting user experience.

A remotely controlled model airplane includes a receiver responsive to signals from a transmitter to control the direction of flight of the model airplane. The receiver, powered by a battery, demodulates the signal transmitted by the transmitter to selectively energize an electrical coil to generate a magnetic field of a first or second polarity. A rudder pivotally attached to the vertical stabilizer includes a magnet responsive to the magnetic fields generated and is urged in one direction or the other resulting in commensurate pivotal movement of the rudder. A hinge interconnecting the rudder and vertical stabilizer urges return to center of the rudder after it has been deflected left or right by the magnet responding to the magnetic field created as a result of a signal transmitted by the transmitter. An electric motor also under control of the transmitter and receiver may be incorporated to rotate a propeller to provide thrust and forward motion of the model airplane. By employing a transmitter to selectively transmit a plurality of signals, control surfaces of the model airplane can be deflected to provide 2-axis control to selectively alter the direction and pitch of the model airplane.

A radio controlled model rotorcraft implemented with features improving ease of flight and flight performance by increasing structural stability, increasing rotorcraft visibility and orientation awareness through the use of multifunctioning, configurable, and aesthetically pleasing components, while also increasing resistance to damage from crashes through use of impact and vibration absorbing components.

A shock absorber for a remote-controlled model car includes a sealing member fixed on the topside of a piston. The sealing member has two opposite flexible portions respectively matching with the flow-guiding holes of the piston, with flow gaps formed between the flexible portions and the upper outer sides of the piston. The flow gap, matching with the extent of an external force imposed upon the shock absorber, can be properly diminished or closed up. Each flexible portion is bored with a flow-adjusting hole smaller than and aligned to the flow-guiding hole of the piston for reducing the flow amount of liquid oil flowing through the flow-guiding hole. When pressed by different-extent external forces, the shock absorber can automatically adjust its buffering force to an excellent condition by adjustment of the flow-adjusting holes and the flow gaps.

A motor vehicle steering control provides two degrees of freedom with a one-handed operation that is simple and intuitive. The control is achieved with a joystick control movable from side to side (e.g. as in an aircraft) in combination with a yoke control which rotates on an axis (e.g. like the steering wheel of a car). The yoke control (giving one degree of freedom) is mounted to the joystick control, the latter of which adds a second degree of freedom. The steering of both the front and rear wheels of a variety of vehicles may be controlled, including vehicles where the operator rides with the vehicle and, as well, remote controlled vehicles where the operator is situated remote from the vehicle. The latter case contemplates remote controlled steering not only of full scale vehicles designed to move or haul some load but also model vehicles such as radio-controlled model cars and the like.

A braking ratio device for a remote control model is composed of a suspending arm and a ratio device. The suspending arm is fixed with a shaft of a servo motor, having a controlled member formed at its one side and a driving member extended out from one end of the controlled member. The ratio device is provided with a pivotal base pivotally mounted on the controlled member, and a ratio base connected with the pivotal base to be able to move axially. A front brake connecting rod and a rear brake connecting rod are respectively inserted through two sides of the ratio base, to alter the distance between the front brake connecting rod and a front braking set, and also the distance between the rear brake connecting rod and a rear braking set, for creating a time difference of braking for the front and the rear braking sets.

A wrench for an engine clutch of a radio control model includes a handle having a receiving space longitudinally defined in the handle. A control unit is rotatably mounted in the receiving space, and includes a first end formed with a press portion and a second end formed with a hook. The press portion presses a centrifugal lever of the engine clutch when mounting and the hook engages to the centrifugal lever when detaching. A drive unit is pivotally mounted to one end of the handle and corresponds to the press portion. The drive unit includes a hole defined in a free end thereof for receiving an input shaft of the engine clutch. A partition is securely laterally attached to the drive unit and has a separation extending therefrom. The separation is provided for easily detaching / mounting a torsion spring of the engine clutch.
