control line

A control line, in the context of model flying or drones, is a thin, strong thread or wire used by a pilot to manage and steer the aircraft. It is attached to the model at a specific point, allowing the operator to apply tension or slack to influence its direction, altitude, or speed. Essentially, the control line acts as a physical connection between the pilot and the model, enabling precise manual control during flight. This method is commonly used in competition flying and traditional model aircraft to achieve controlled, circular flights or specific maneuvers.
