A wide range of engines were fitted, including the Anzani three cylinder inverted Y radial engine, the Anzani 6-cylinder two row radial and the Gnome. The last, a rotary engine, was usually covered over the upper part to screen the pilot from oil spray; the Anzanis were mounted uncowled. They all drove large, rather broad chord propellers. The very broad chord, low aspect ratio tailplane was constructed like the wing with a flexible rear surface acting both to improve stability and, by warping, act like conventional elevators, its trailing edge extending well beyond the end of the fuselage. A small, near rectangular, one piece, rigid fin was pivoted near its leading edge from the extreme tail. The Types M and N had a tailskid undercarriage. A transverse steel bar was fixed at each end to an ash V-strut from the lower fuselage and further braced with a steel V-strut from its centre. A pair of axles, hinged at the centre of the bar, passed through the vertices of the ash struts via rubber shock absorbers with the mainwheels, slightly toed out and apart, beyond them. Early versions of the undercarriage used a single axle rather than a split one. There was an unusually long, curved, tall tailskid at the rear to keep the long tailplane clear of the ground. Apart from basic specification (dimensions, weights and speed) in Laérophile and Jane's All the World's Aircraft 1913, no records of the Type M2 are currently known. The first flight dates are not currently known, nor which type flew first, but there are reports of a Type N, piloted by Renée Caudron, flying on 23 December 1911. Fitted with the Anzani engine, it flew an out and return flight from Caudron's Le Crotoy base to Pointe-Saint-Quentin at . Two days later it was on display at the 1911 Paris Salon. It was re-engined with a Anzani for an English owner, E.W. Ewen, who flew it home across the English Channel on 2 May 1912. Flown by Maurice Guillaux it took part in a circuit of London race in June 1912, starting from Hendon, but retired from lack of fuel just before the end when it looked a likely winner. After many modifications it was on display at the Olympia show in February 1913. In September 1913 F. Goodden demonstrated it the Aerial Derby at Hendon, powered by a Anzani; it had been entered for the race with the engine but did not compete.
