The Chu Hummingbird was an experimental co-axial helicopter developed by Chinese aviation engineer Major General C.J. Chu (朱家仁) in China during the 1940s in two versions, designated the Model A and Model B.

Model A was a single seat double rotor test craft used for static (non-flying) test and made its debut in 1945.^[1] This model was destroyed when the rotor broke off.

A replacement craft named Model B was introduced in 1948 and was able to fly, but the aircraft was abandoned when Chu left for Formosa.^[2]

Not much is known about either model, as they were abandoned in China after 1949 as Chu exiled to Taiwan after the formation of the People's Republic of China.

A successor model, CJC-3 was developed by Chu in Taiwan in the 1950s.
