The American Eagle A-1 of 1926 was designed by Robert T McCrum and possibly Waverly Stearman. First flown on 9 April 1926, the model designation didn’t appear until late 1927.

The company’s initial effort was designed to replace war-surplus Standards at the Porterfield Flying School. The unit cost was $2,450, $2,515 in 1929, $2,985 in 1930. After receiving its ATC (17), the model designation was changed to A-101, offering 100hp Curtiss OXX-6, 150hp Hisso (2-55) as A Special in 1929 [511], 125hp Ryan-Siemens (2-48), 120hp Anzani, and 125hp Quick as A-1 Special [X4387] (length: 23’5″-24’6″).

The design had dangerous spin characteristics, resulting in several fatal crashes, and was dropped in 1928 in favor of A-129.
