Robinson Helicopters R22 Beta Ii vs Robinson Helicopters R44 Cadet vs Robinson Helicopters R66
The Robinson R22 Beta II is a lightweight, two-seat piston helicopter commonly used for primary training and short local flights. Its range is the shortest of the three, best suited to nearby point-to-point hops and pattern work rather than longer cross-country missions, and its passenger capacity is limited to one passenger plus the pilot. The Robinson R44 Cadet is also piston-powered but steps up in size and capability. Although derived from the four-seat R44 line, the Cadet is configured for three seats total, giving more useful load and cabin space than the R22 while still targeting training and cost-conscious operations. Its range is typically greater than the R22, making it more practical for extended local touring and longer training legs. The Robinson R66 moves into the turbine category, offering higher power, increased performance margins, and generally greater range than either piston model. It carries up to five people (pilot plus four passengers), making it the most suitable for passenger-carrying, utility work, and longer trips where speed, payload, and turbine reliability are priorities.
