 Initial testing showed a top speed to 178 mph, but with enlarged tail surfaces and a Townend cowling, it recorded 190 mph at 8,000 ft.The aircraft performed poorly, with a poor rate of climb and a high landing speed.The USAAC did not order the aircraft for production and on 7 February 1931, the prototype was destroyed when a propeller blade failed and the engine tore loose from its mounts.
