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 toy helicopter is a fun flying toy suitable for children and adults to play with. However, due to the high difficulty of operation and the need for certain skills and experience, it is recommended to operate under professional guidance.
