Enstrom Helicotper F 28f vs Robinson Helicopters R22 Beta Ii vs Robinson Helicopters R44 Raven I
The Enstrom F-28F, Robinson R22 Beta II, and Robinson R44 Raven I are all light civil helicopters, but they differ in role and capability. The Enstrom F-28F is typically considered a light turbine helicopter aimed at utility, training, and personal transport, offering the smoothness and reserve power associated with a turbine engine. The Robinson R22 Beta II is a very light, piston-powered two-seat helicopter commonly used for primary flight training and low-cost personal flying, making it the smallest and least capable for carrying people and fuel. The Robinson R44 Raven I is a light, piston-powered four-seat helicopter positioned as a step up from the R22 for family or business travel, with more useful load and comfort. In passenger capacity, the R22 carries two people including the pilot, while the R44 carries four. The Enstrom F-28F generally seats four to five depending on configuration. For range, the R22 is generally shortest, the R44 is longer, and the F-28F is typically comparable to the R44 or better depending on fuel and mission fit.
