It was a single-bay biplane powered by a 300 hp (224 kW) M-6 inline engine with a retractable radiator. The prototype first flew in 1927 and entered production with an order for 55 for use as an intermediate trainer. Problems with the original strut-based wing bracing resulted in many aircraft being modified to use bracing wires." ] ,
