RC Helicopters

A remote control helicopter is a helicopter that can be controlled to fly from a long distance. The take-off, flight, landing and other actions of the remote control helicopter are mainly completed by the rotors. When the main rotor blades rotate, an updraft is generated relative to the air, which naturally forms a lift. By using the rotation speed of the rotor and the angle change of each blade, the aircraft completes various flight actions such as take-off, lift, 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 relative to the rotating shaft, pulling the RC helicopter forward. The same goes for making the RC helicopter fly left or right.
