The Robinson R-44 Raven is a single-engine light rotorcraft produced by the Robinson Helicopter Company. Built for general aviation operations, it features an enclosed cabin accommodating a pilot and three passengers across two rows of side-by-side seating. The aircraft utilizes a semi-rigid main rotor and a skid landing gear arrangement, and it is powered by a horizontally-opposed piston engine.
Developed by Frank Robinson and his engineering team, the helicopter took its initial flight in March 1990 and achieved federal certification near the end of 1992, with deliveries commencing shortly thereafter. Over the subsequent decades, the type evolved through several iterations, including news-gathering variants, versions equipped with hydraulically assisted flight controls, and models featuring more powerful fuel-injected engines. It has also been adapted into cargo-focused configurations and experimental unmanned drone platforms, while test programs have explored alternative diesel powerplant options.
