The Cicaré CH-8 is a series of ultralight, kit-built helicopters based on a single-seat Argentinian design from the late 1980s.[1] It was later developed into a tandem two-seater, and later into a tandem side by side ULM and remains in production.

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 ski,d making easier to get a ground reference while landing. The frame is built on aeronautical SAE 4130 chrome molybdenum steel tube [2] 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 tailplape, with small endplate fins, and the lower one ends with a tailskid.
Operational history
100 Helis were built between 2014 and 2021.[3]
