About the ROBINSON HELICOPTER COMPANY R44 II

The Robinson R44 is a light, single-engine helicopter produced by the Robinson Helicopter Company. Introduced in 1992, the R44 has become one of the most popular general aviation helicopters in the world. The R44 fits into the category of light utility helicopters and serves a wide range of roles, from personal and business travel to flight training, law enforcement, and sightseeing. Its design carries forward Robinson's reputation for creating versatile, cost-effective, and reliable helicopters. The R44 is an iteration of the earlier R22, designed with improved performance, capacity, and safety in mind. The R44 Raven II, a notable variant, was introduced in 2002. This model features a more powerful engine, improved aerodynamics, and a refined, modernized cabin. It is powered by a fuel-injected Lycoming IO-540-AE1A5 engine, which delivers 245 horsepower, enabling the helicopter to cruise at speeds of up to 130 knots (approximately 150 mph). One of the primary motivations behind the development of the R44 was to address the limitations of the R22, particularly in terms of passenger capacity and overall performance. While the R22 is a two-seater, the R44 can accommodate four occupants, making it a more flexible option for various applications, including small group charters and air tours. The aircraft's relatively low operational costs, reliability, and ease of maintenance have made it particularly attractive to flight schools and private owners alike. Since its introduction, the Robinson R44 has been lauded for its straightforward design, cost-effectiveness, and robust performance. It quickly established itself as a workhorse in the general aviation category, serving diverse roles. Its popularity is evidence of the successful design philosophy of Robinson Helicopter Company, which emphasizes simplicity, reliability, and affordability. Overall, the R44 represents a significant advancement in light helicopter design, continuing to be a favorite in the industry for over three decades.
