 The main landing gear retracted into wheel wells in the fuselage just forward of the lower wing and the tail wheel retracted into the fuselage.This aircraft was initially powered by a Wright R-1510-92 engine but this was unsuitable so the aircraft was re-engined with a 775 hp (578 kW) Wright R-1670 fourteen cylinder, two row, air-cooled radial engine, which was also unsatisfactory.Both of these engines were prototypes and neither went into production.
