The Focke-Wulf Fw 61 was a twin-rotor helicopter technology demonstrator developed by Heinrich Focke and Gerd Achgelis. Its fully controlled free flight in 1936 established a foundational practical-helicopter milestone, and the design later became known as the Focke-Achgelis Fa 61 during its public record-setting demonstrations.
