The forward flight of a remote-controlled helicopter is caused by the fixed pattern of changes in the angle of each blade at different positions. The tension generated by the rotor tilts forward relative to the axis of rotation, pulling the remote-controlled helicopter forward. The same principle applies to flying a remote-controlled helicopter to the left or right.

A remote-controlled aircraft refers to an aircraft that can control flight from a long distance. Most remote-controlled aircraft are sold as all-in-one machines, and the manufacturers have already debugged them. For some beginner models, they have reached the state of ready to fly, and the prices are relatively low.
