Design and development
Marcel Violet was a French racing driver who designed his own two-cylinder, two-stroke engines. He also designed a two stroke horizontally opposed flat-four, which was built under licence at L'agence general moteurs "Ava" by Jean Aubry of the Société J. Thibault, G Aubry et Cie, alloy metal specialists, as the Ava 4A. It only produced and was intended to power small, low cost, single seat aircraft, replacing the aging Anzanis and completing with the French Mengin Type B and the older British Bristol Cherub engines.The Ava 4A was on display at the November 1936 Paris Salon. It powered several prototypes and also the forty-six examples of the series production variant of the Farman Moustique, the F.451.
