Bell 525 Relentless vs Embraer Legacy 650 E vs Enstrom 480b vs Robinson R66

The Bell 525 Relentless is a large, fly-by-wire, twin‑engine turbine helicopter aimed at offshore and executive missions. It typically carries around 16 passengers in a high-density layout (fewer in VIP configurations) and offers long helicopter range on the order of roughly 500–600 nautical miles. The Enstrom 480B and Robinson R66 are light, single‑engine turbine helicopters for utility or private use; the 480B generally seats about 5 (including the pilot) with a range roughly in the 300+ nautical mile class, while the R66 typically seats about 5 with a similar, often slightly higher, roughly 300–350+ nautical mile range depending on configuration and reserves. The Embraer Legacy 650E is a large-cabin business jet rather than a rotorcraft; it commonly accommodates about 13 passengers and has far greater range—around 3,900 nautical miles—making it the clear choice for long, nonstop intercity or intercontinental travel, while the helicopters prioritize vertical access and short-to-medium legs.
