The '''Chu Hummingbird''' was an experimental co-axial helicopter developed by [[China|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 March 1948. 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]].

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

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