Design and development

The piston engine-powered CH-8 ultralight series use the traditional "penny-farthing" layout with two-bladed main and tail rotors. The main rotor is formed from composites and is a teetering, semi-rigid design with 6° of twist. The pod-and-boom fuselage has a carbon fiber and epoxy resin cabin with a long transparent forward-opening canopy. This large windshield allows the pilot to see the tip of the skid making easier to get a ground reference while landing. The frame is built on aeronautical SAE 4130 chrome molybdenum steel tube and welded in spatial reticulated configuration. The steel frame also carries the engine, semi-exposed behind the accommodation and connected to the main rotor shaft by a belt drive. A slender aluminium boom, strengthened by a pair of long struts to the lower fuselage frame, carries both the tail rotor and swept fins. The upper fin is topped with a short horizontal T-shaped tailplate, with small
