New Gnome Rotary Engine Production Resumes after 100 years

GNome Monosoupape Rotary Engine

Gnome Monosoupape Rotary Engine manufactured by CAMS

Production of Gnome Monosoupape 100 hp rotary engines has resumed after a lapse of nearly a century. These high quality, period authentic engines are now manufactured by Classic Aero Machining Service of Blenheim, New Zealand. For those who want to experience exactly what it was like to fly during the Great War era, the smells, sounds and other characteristics of a rotary are unlike any other engine. They were fitted to many aeroplanes of the period, including Sopwith.
