What basic knowledge do you need to learn to make a model helicopter?

First, don't be afraid of suffering and annoyance. Because there will be many problems!

Second, you should have basic electrical knowledge and awareness of safe operation.

Third, we should have the basic concepts of driving, flying and sailing.

Fourth, for the altitude model, you must respond quickly. You must also have the skills to listen to the oncoming plane and operate in the opposite direction.

Fifth, we must have psychological endurance. The beloved model will crash, crash and sink into the water at any time.

Sixth, we must have certain practical ability.

Remote control helicopter, that is, a helicopter that can control flight from a distance. It can be divided into toys, airplane models, civil and military. At present, the most common model is the model airplane remote-controlled helicopter. Remote-controlled helicopters can be divided into electric helicopters and oil helicopters. The biggest difference from a real helicopter is the addition of an aileron to better control the direction of the rotor.

The take-off, flight, landing and other actions of the remote-controlled helicopter are mainly completed by the rotor. When the main rotor blade rotates, it will produce an updraft opposite to the air, which naturally forms a rising force. Using the rotation speed of the rotor and the angle transformation of each blade, the aircraft can complete many different flight actions such as take-off, lifting and landing. The forward flight of remote-controlled helicopter is caused by the change of the angle of each blade at different positions according to a fixed law. The pulling force generated by the rotor tilts forward relative to the rotating shaft, pulling the remote-controlled helicopter forward. The same is true for flying a remote-controlled helicopter to the left or right.
