The Praga E.114 was a single-engine sport airplane, designed and manufactured by the Czechoslovakian company ČKD-Praga. In total 275 were produced with the first flight in 1934. The last E.114 variant was the -M, fitted with a more powerful engine that changed the nose profile and increased its length, the wing carried noticeable dihedral and it was fitted with a tailwheel rather than a skid. This example was restored in 1965 and came to the Letecké Muzeum Kbely in 1993.
