The Humming Bird light helicopter was designed by Major-General C.J. Chu in China during 1945. His Model A Humming Bird was a tiny coaxial helicopter with an enclosed fuselage pod and a 125hp Kinner engine, which was destroyed in ground testing. The subsequent Humming Bird B was similar, but it is not clear whether either helicopter flew - and the Humming Bird B was abandoned in China when Chu fled to Formosa. In 1952, he produced a small tandem-rotor helicopter known as the CJC-3 which was a side-by-side two-seater with a centrally-mounted 190hp Lycoming engine and fixed four-leg undercarriage. No further information is available. R.Simpson "Airlife's Helicopter and Rotorcraft", 1998
