for the Cleveland Speed Foundation, Laird was already famous in the air racing circuit. It had a large radial engine and an extremely faired windshield. Other than being a biplane, it was similar in appearance to the Gee Bee, a more famous racer from the period. It was an advanced design for the time because of the relatively clean aerodynamic construction and tight engine cowling. The Super Solution was the first winner of the Bendix Trophy race from

Development

Construction of the Super Solution started on 8 July 1931. The aircraft was complete and test flown at Ashborn Field in Chicago by 22 August 1931. Further changes were made by the Christopher Bros. in Wichita, Kansas in 1932, such as raising the seat, installing a sliding canopy, and adding retractable landing gear.

Design

Two engines were used in the Solution, the second being a geared variant that allowed a lower propeller rpm with a larger propeller. The engines ran with high-compression pistons and "doped" leaded fuel. Both produced over 500 hp from the standard 375 hp P&W R-985 Wasp Jr. S2A engine of the day.

Operational history

Initial flight tests proved the aircraft required more rudder area to maintain stability and the fixed pitch propeller needed to be adjusted to allow takeoffs under a mile in length. *1931
