Developed based on the “Yangcheng 54” and “Yangcheng 55”, the Guangdong Aircraft Repair Factory Yangcheng 56 and Yangcheng 57 Nanxiong reconnaissance/bombers first flew in 1930. One each of this type of aircraft were built.
The Yangcheng 56 was equipped with the Waco ATO, dismantled from a crash, and the Yangcheng 57 used a Pratt Whitney Wasp engine. The Yangcheng 56 was built on August 30, 1930, and the Yangcheng 57 was built on September 22, named “Nanxiong”. The test flight was conducted by Ding Jixu and Tan Shou. The test flight found its oil system and manoeuvrability were poor.
After the two aircraft were made, they were incorporated into the third squadron of the Guangdong Air Force. They were once used for reconnaissance of the Red Army of Workers and Peasants in southwestern Jiangxi.
