has abstract	The Hoppi-Copter was a functional backpack helicopter developed by the American company Hoppi-Copters Inc. founded by in the 1940s. The original Hoppi-Copter consisted of two contra-rotating rotors on a pole attached to a motorized backpack. Although it was capable of flight, it was extremely hard to control. Later prototypes of the Hoppi-Copter included versions with the pilot in a sitting position, and were in effect miniature one-man helicopters of a more conventional design, though retaining the contra-rotating rotors and thus obviating a tail rotor. Despite interest from the British Ministry of Supply in the 102 and 104 models, none were adopted commercially.
