Enstrom Helicotper 280fx Shark vs Enstrom Helicotper 480b G vs Enstrom Helicotper F 28f vs Robinson Helicopters R44 Cadet vs Robinson Helicopters R44 Raven I vs Robinson Helicopters R66
All six are light civil helicopters, but they split into piston trainers/tourers versus turbine utility. The Enstrom F-28F, 280FX Shark, and 480B-G are two-seat or three-seat light pistons aimed at training and personal use; among them, the 480B-G is generally the most capable and longest-legged, while the F-28F and 280FX are typically shorter-range and more trainer-oriented. Robinson’s R44 Cadet and R44 Raven I are four-seat piston helicopters in the same broad category, commonly used for training and private transport; the Cadet is configured around two seats (with simplified equipment and lower weight) and tends to have less usable load and range than the Raven I, which is the more fully equipped four-seat variant. The Robinson R66 is a light turbine helicopter with higher cruise capability and usually the greatest practical range and load flexibility of this group, carrying up to five seats (including the pilot), making it better suited to longer trips and higher-demand missions than the piston models. Capacities thus run from two seats (280FX, F-28F, often R44 Cadet) to three (480B-G) to four (R44 Raven I) to five (R66).
