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 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 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.
