In order to meet the demand for mailplanes, Waco aircraft developed two models during 1929, the JYM and the JWM.
The JYM was a taperwing model based on the earlier ATO design but with a 14-inch fuselage stretch to provide further cargo capacity compared with the earlier design. It was powered by a 300 hp (220 kW) Wright J-6-9 engine and had a single seat cockpit for the pilot.[1]
The JWM was a straight-wing model based on the ASO, also with a 14-inch longer fuselage and was fitted with a 330 hp (250 kW) Wright R-975 powerplant.[1]
Operational history
Four Waco JYM aircraft were delivered to Northwest Airways (later Northwest Airlines) in 1929 and were operated on the 892 mi (1,436 km) CAM-9 airmail route from Chicago to Minneapolis via Milwaukee, Madison and La Crosse.[2] All four Waco JYM's still exist, with the third JYM NC631N on display at the Historic Aircraft Restoration Museum (HARM) at Dauster Field near St Louis, Missouri, wearing its 1929 NWAL CAM-9 route markings.[3]
