Four-channel transverse dual rotor helicopter

Abstract

The present invention provides a four-channel transverse dual rotor helicopter, comprising a frame with a battery encapsulated inside it, an empennage breadthwise located at the afterbody of the frame, an aircraft wheel assembly fixed at the bottom of the frame, wherein, two cantilever bars of left and right are connected to the frame, breadthwise located at the two sides of the frame, and capable of rotating around axes of themselves; the left and right cantilever bars are separately via a group of linkage mechanism connected to left and right steering engines located at the frame for driving the left and right cantilever bars to rotate around axes of themselves; the ends of the left and right cantilever bars are separately provided with a group of rotor wing mechanism; the motors in the two groups of rotor wing mechanism, and the left and right steering engines are connected to a signal receiver located in the frame; the motors are variable speed motors. The present invention is easy to control, so as to make the beginner without controlling foundation also capable of controlling the helicopter to fly stably. At the same time, the simplified mechanical structure of the helicopter reduces the production cost, also greatly improves the performance stability of the helicopter.
