9-502: 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. The JWM

18-485: A cockpit under the upper wing and ahead of the pilot, who had a separate cockpit. It had a split-axle fixed undercarriage and a tailwheel. The main undercarriage was fitted with hydraulic shock absorbers, unusual at the time on a light aircraft. The fin could be trimmed on the ground to offset engine torque, and the tailplane could be trimmed in flight. Initially it was powered by a Curtiss OX-5 water-cooled 90° V-8 engine producing 90 hp (67 kW). Its first flight

27-520: 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. One Waco JWM aircraft was built. The sole survivor NX8550 is also preserved at HARM, wearing the markings of the "Art Davis Air Circus".

36-524: The wing installed, S or T meaning Straight or Tapered wing, and the final O indicating it was a derivative of the 10. An -A suffix indicated an armed variant intended for export. Apart from the water-cooled V-8 Curtiss and Hispano-Suiza engines, all of the rest were air-cooled radials . Other engines were fitted experimentally, without unique designations, including the Rausie , Ryan-Siemens , and 115 hp (86 kW) Milwaukee Tank engine. This last engine

45-594: Was a range of three-seat open-cockpit biplanes built by the Advance Aircraft Company , later the Waco Aircraft Company . The Waco 10 was a larger span development of the Waco 9 , both single-engined three-seat single-bay biplanes constructed around steel-tube frames. The wing covering was fabric, and both upper and lower planes carried ailerons, which were strut linked. The two passengers sat side by side in

54-480: 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. 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. All four Waco JYM's still exist, with

63-493: Was also much used as a trainer and by small operators for charter flights. In 1928, after the Waco 10 had entered production, Waco changed its designation system so that the basic model 10, powered by a 90 hp (67 kW) Curtiss OX-5 engine became the GXE . Later aircraft used three-letter designations, the first denoting the engine (except for the two mailplanes), the second denoting

72-593: Was an air-cooled version of the Curtiss OX-5, and was intended as an aircraft engine. The JYM and JWM were mailplane derivatives with a 14" fuselage stretch. In the 1990s the unrelated The WACO Aircraft Company in Forks, Washington offered a homebuilt kit version of the ATO model. The WACO 240-A was a straight-wing fighter, built for export, powered by 240 hp (180 kW) Wright engine. At least six were bought by

81-439: Was in 1927. It was numerically the most important type to be built by Waco, with at least 1,623 built over a period of 7 years from 1927 to 1933 and was fitted with a very large variety of engines of radial and V configuration. The Waco 10 turned out to have excellent handling, and there was a ready supply of war-surplus Curtiss engines. It was widely used for the popularisation of aeronautics through barnstorming and joyrides, and
