The Consolidated O-17 Courier (company designation Model 2) was an observation and training aircraft used by the United States National Guard.
Development
A parallel development to the Consolidated PT-3 series, the XO-17 was a converted PT-3 with such refinements as improved fuselage streamlining, oleo shock absorbers, wheel brakes, balanced elevators and increased fuel capacity.[1]
It was used almost exclusively as a cross-country flying, gunnery, photographic and radio trainer.[2] The O-17 had a removable fairing (carrying a Scarff ring mounting for one .30 cal (7.62 mm) trainable Browning machine gun).
The Royal Canadian Air Force purchased three generally similar aircraft, two Model 7 landplanes and one Model 8 floatplane, the latter with the same float gear as the NY series.
The sole XO-17A was converted from the PT-3 as a demonstrator that failed to secure any orders.[2] It was later fitted with the experimental Packard DR-980 Diesel engine of 225 hp (168 kW).[1]
The Model 15 was also an O-17 type airframe fitted with a Pratt & Whitney R-1340 engine. It too failed to win any contracts.[2]
