Harold E. Emigh founded the Helicopter Research Corporation in 1954 to develop and market a single-seat personal helicopter. Known as the Helicom Commuter Jr Model H-1 A, the prototype first flew in 1960, and was sold both in ready-to-fly form and as a kit for assembly by amateur constructors. A ground trainer version was developed also, mounted via a gimbal to a castoring base which was too heavy for the helicopter to lift from the ground.
The commercial rights were sold to Southern Pacific Aircraft Co and then to International Helicopter Inc of Mayville, New York, with the machine being refined along the way as the Commuter II.
