04/30/2008. Remarks by Walter van Tilborg: "The M.D.80 ABC was a private venture project of Avions Marcerl Dassault and the company's smallest (and so far only) light plane. It was intended as a basic trainer for the French AF and had to compete with similar designs, the Nord 2800 and Morane-Saulnier M.S.730. Only a single prototype was built and was first flown at Melun-Villaroche by Kostia Rozanoff on October 16, 1950 and had a 220-240 hp Renault 6Q piston engine. Plans to re-engine the M.D.80 with a 240 hp Potez 6D-30 were almost certainly never carried out and development was soon stopped."
