Jane's All The World Aircraft 1919
M. Vendome, one of the earliest of French constructors, produced in 1916 a machine somewhat after the style of the Moineau.
In the fuselage, one on each side, were two Monosoupape Gnome engines, each driving a shaft to a bevel gear, which in turn drove a tractor airscrew. Thus the machine had two rotary engines turning in opposite directions, which would give it considerable lateral stiffness (though not stability), owing to their gyroscopic action.
A gunner sat in the nose of the machine and another behind the pilot.
As in the case of the Moineau, it was never put into production.
