Enstrom Helicotper 480b vs Enstrom Helicotper 480b G vs Robinson Helicopters R66 vs Robinson Helicopters R66 Marine

The Enstrom 480B and 480B‑G are both light, single‑engine turbine helicopters in the same basic size class as the Robinson R66, generally used for training, utility, personal transport, and light commercial work. In category, the 480B‑G is essentially a mission‑configured 480B variant (often aimed at specialized government/utility roles) rather than a fundamentally different aircraft, so its core performance and seating are broadly similar to the standard 480B. For range, the Robinson R66 family is typically regarded as having longer legs than the Enstrom 480-series in comparable day‑to‑day operations, while the R66 Marine is usually similar to the standard R66, with marine equipment affecting useful load more than nominal range. For passenger capacity, all four are commonly arranged as four-seat helicopters (pilot plus three passengers), with the R66 and R66 Marine widely marketed as four-place and the Enstrom 480B/480B‑G also typically operated as four-place in standard configurations. Actual usable range and payload vary notably with fuel, equipment, and conditions.
