The Guangzhou/Kunming 1st Aircraft Manufacturer Yang Ch’eng 74, 75, 76 and 77 were a modified copy of the Douglas O-2MC-3. The fuselage is shorter than the O-2MC.
Based on the “Douglas O-2MC” reconnaissance/bomber, the fuselage structure is made of wood, and the cross section is changed from rectangular to oval. The two-wing layout, the shape of the vertical tail and rudder have also been modified.
The first Yangcheng 74 was manufactured on March 16, 1934, and more than 10 were built.
Ten of these aircraft were incorporated into the third and fifth squadrons of the Guangdong Air Force, and they participated in the Red Army operations that encircled southwestern Jiangxi. After the outbreak of the Anti-Japanese War, the performance of the aircraft was completely behind the Japanese aircraft, so it retreated to the second line, used as Yichang shooting training class and parachuting training class, and then transferred to Chengdu Flying Non-commissioned Officer School as a trainer.
