Benefits of technology

[0008]An object of the present invention is to provide a linkage device for a remote control model helicopter with coaxial and counter rota...

Problems solved by technology

However, the forward and backward device thereof has a disadvantage that, when the rotating plane of the lower rotor tilts forwardly and the helicopter flies forwardly, under the action of a centrifugal force of the flybar, the upper rotor would produce an opposite equal force tilting backwardly to counteract with the force driving the helicopter to fly forwardly; and vice versa.
Thus this type of helicopter has relatively weak forces of flying forwardly and backwardly and is vulnerable to airflows; a strong wind may stop the helicopter.
The conventional three-channel model helicopter also has the problem of the weak forces of flying forward and backward.
Because the tail motor is related wi...

Embodiment Construction

[0020]Referring to FIG. 1 of the drawings, according to a preferred embodiment of the present invention, a linkage device for a remote control model helicopter with coaxial and counter rotating double-propeller comprises a servo steering engine operating system (only a forward and backward servo steering engine 1 and a leftward and rightward servo steering engine 16 showed), a tail motor operating system (only a tail motor 2 and a screw propeller 3 showed) and a receiver controlling device 4. The receiver controlling device 4 is respectively connected to the forward and backward servo steering engine 1, the leftward and rightward servo steering engine 16 and the tail motor 2 via electric wires and able to control the forward and backward servo steering engine 1 and the tail motor 2 to link simultaneously to control the forward and backward servo steering engine operating unit and the tail motor operating system to act simultaneously when the helicopter flies forwardly and backwardly...

Abstract

A linkage device for a remote control model helicopter with coaxial and counter rotating double-propeller includes a servo steering engine operating system, a tail motor operating system and a receiver controlling device; the servo steering engine operating system includes a forward and backward servo steering engine operating unit and a leftward and rightward servo steering engine operating unit; the receiver controlling device is connected to both the servo steering engine operating system and the tail motor operating system and for controlling the forward and backward servo steering engine operating unit and the tail motor operating system to link simultaneously. Compared to a conventional three-channel or four-channel model helicopter, the model helicopter using the linkage device has better resistance to winds and meets requirements to fly fast against winds outdoors.

Description

CROSS REFERENCE OF RELATED APPLICATION[0001]This is a U.S. National Stage under 35 USC 371 of the International Application PCT / CN2010 / 002183, filed Dec. 28, 2010.BACKGROUND OF THE PRESENT INVENTION[0002]1. Field of Invention[0003]The present invention relates to a linkage device for a model helicopter, and more particularly to a linkage device for a remote control model helicopter with coaxial and counter rotating double-propeller.[0004]2. Description of Related Arts[0005]The conventional remote control model helicopter with coaxial and counter rotating double-propeller mainly comprises a landing gear, a body, a receiver controlling device, a motor power transmitting device, a rotor lifting device, a flybar device and a forward and backward device.[0006]The forward and backward device of a conventional four-channel model helicopter is embodied as an operating unit of a forward and backward servo steering engine in a servo steering engine controlling system which is realized by a ma...
