General Characteristics
The Stearman-Hammond Y-1S was a unique, two-seat experimental aircraft designed in the mid-1930s with safety and ease of control as its primary goals. Its unusual pusher propeller configuration and tricycle landing gear were radical for the time.

Design and Powerplant
- Engine: One Menasco B6S six-cylinder air-cooled inverted in-line engine.
- Power Output: 150 hp (112 kW).
- Propeller: Two-bladed propeller mounted behind the wing trailing edge in a pusher configuration.
- Landing Gear: Featured a tricycle landing gear (nose wheel and two main wheels), a highly advanced and rare feature in the 1930s, designed to prevent ground looping.
- Flight Controls: Simplified three-control system. Notably, yaw and roll were controlled by combined rudders/ailerons (“rudderons”), intended to be easier for non-professional pilots.
- Configuration: High-wing, twin-boom monoplane.
Performance and History
- Maximum Speed: 204 km/h (127 mph).
- Cruise Speed: 185 km/h (115 mph).
- Operational Range: Approximately 725 km (450 miles).
- Historical Note: The Y-1S won the U.S. Bureau of Air Commerce’s competition for a safe, low-cost private aircraft, but poor sales due to its high price and unusual configuration led to the company’s collapse.
- Legacy: Although a commercial failure, its innovative design elements, particularly the pusher engine and tricycle gear, influenced later aircraft safety and general aviation design.
