Design and development
The W.F. Stewart Company was a custom builder of wooden auto bodies. When factory-built steel bodies overtook wood construction, the company broke into the aviation market with the Stewart M-1, an all-wood monoplane. Sensing wood construction was about to be overtaken by all-metal aircraft, the Stewart M-2 was developed.The M-2 was an all-metal, twin-engined aircraft with conventional landing gear, powered with Wright J-6 engines. 225 hp Packard DR-980 engines were later installed and tested. Townend rings were used on the re-installed Wright J-6 engines.
