Introduction of remote control helicopter
A remote control helicopter is a helicopter that can control the flight at a long distance. It can be divided into toys, model airplanes, civilian, military, etc. Now the most common is the model airplane remote control helicopter model. The remote control helicopter is divided into two types: electric and oil-powered. The biggest difference from a real helicopter is that it has an additional aileron to better control the direction of the rotor.
The actions of remote control helicopters, such as take-off, flight, and landing, are mainly completed by the rotors. When the main rotor blades rotate, an updraft relative to the air is generated, which naturally forms an upward force. The rotation speed of the rotor and the angle change of each blade are used to cause the aircraft to complete various flight actions such as take-off, ascent, and landing. The forward flight of the remote control helicopter is caused by the change of the angle of each blade in different positions according to a fixed law. The pulling force generated by the rotor tilts forward with respect to the rotating shaft, pulling the remote control helicopter forward. The same goes for making the remote control helicopter fly to the left or right.
