Design and development edit
Curtiss started work on a small six-cylinder engine in May 1927.[1] The engine was unusual in its design with aluminium cylinders mounted at 60°, so that it was in effect two staggered three cylinder engines.[2] The engine was first run in December 1927, and was taken to market producing between 170 and 180 horsepower (127 and 134 kW) at 1,800 rpm.[1]
