The Lockheed Brothers left the Company after the Detroit merger and set up the Airover Company, later called Alcor, to build the Uni-twin, with two Menasco engines side-by-side in the nose, driving two propellers. The name of the company was changed to Lockheed Vega when it became a subsidiary of the revived parent organization. The Lockheed Vega Twin then named Olympic Duo-4, crashed 1938.
The Vega Starliner was a five/six-seat low-wing cabin monoplane with retractable landing gear and an unusual powerplant. This comprised two 194kW Menasco C6S-4 inline engines, mounted side-by-side, and coupled to drive together, or independently in emergency, a single propeller. First flown on 22 April 1939, the Starliner was abandoned after some 85 flight test hours as there was no demand for an aircraft in this category.
