04/30/2009. Remarks by Ray Watkins: "Aero Vodochody Akciová Spolecnost (Aero Vodochody Co. Ltd.) was established by the Czech Government outside Prague in 1953. It is known as Aero Vodochody to distinguish it from the Letadla Továrny Aero which was established in 1919 at Prague, but ceased to exist after WW II following nationalization of the aviation industry. Products of the earlier company are generally referred to as Aero Prague designs.

The HC-2 Heli-Baby was designed by Jaroslav Šlechta and had its first flight in 1953. It underwent a protracted development and was the first helicopter of Czechoslovakian design to enter production. A small number were produced for the Czech military with the type designation of VR-2. Flown in an over-all red colour scheme, the pictured aircraft was given the temporarily civil test registration OK-45.

The photo source, Czechoslovakian national VZLU (Výzkumný a zkušební letecký ústav, aeronautical research and test institute), was founded in 1922, and had a major design role under the general direction of Aero Vodochody."
