Remarks by Walter van Tilborg: "The KV-3A motor glider was developed by Roger Kieger and Georges Vaisse (hence KV-3A) and was built by their company Lorraine Aviation (trading as lorAvia) at Yutz. It was based on a Scheibe SF-28 Tandem Falke fuselage and tail surfaces, fitted with shortened Lorraine LCA-12 (license-built version of Scheibe SF-27) glider wings and a 35 hp Hirth 493 engine. Registered F-WAQI it first flew towards the end of 1985. Later the aircraft was redesignated KV-3B when a much more powerful 95 hp Hirth F30 engine was installed, making the aircraft suitable for use as a glider tug. Thereafter development of the KV-3 was halted, however, Lorraine did build a two-seat refinement, the KV-5."
