Jaroslav Šlechta became chief designer in 1934 and designed the Praga E-114 Air Baby aircraft, which became a commercial success. The aircraft was sold to France, Iran, Romania and to Britain. Most of the British aircraft were manufactured locally in Manchester under a licence, by F. Hills & Sons as the Hillson Praga. 126 aircraft were ordered until 1946. Šlechta remained with Praga post war, designing the E-55 general purpose aircraft.
