De Rouge

   The firm designed and built 2 helicopters and 2 biplanes. The first helicopter may not have been finished. It had a small ragged-looking 4-blade rotor and a 3-outrigger tail. The second, marked II on the tail, had a single rotor of some 8 sqm in area and 5 m in diameter, whose torque was to be balanced by a single huge square fin at the tail: it was to be powered with an Anzani and was supposed to carry 60 kg over its weight of only 130 kg. Perhaps it flew.
