Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Enstrom 480b vs Robinson R66

The Bell 525 Relentless and the Enstrom 480B and Robinson R66 are helicopters, while the Cessna 208B Grand Caravan EX is a fixed‑wing utility turboprop. In category terms, the Bell 525 is a larger, twin‑engine transport-class helicopter designed for higher-speed, longer-range missions; the Enstrom 480B and Robinson R66 are single‑engine light helicopters aimed at simpler utility, training, and personal or light commercial use. For range, the Grand Caravan EX typically offers the longest legs in practical operation for point-to-point travel, while the Bell 525 is generally the longest‑range helicopter of the group; the R66 and 480B are shorter-range by comparison. In passenger capacity, the Grand Caravan EX usually carries the most people, commonly seating up to about 9 passengers (depending on configuration). The Bell 525 typically seats around 16 occupants in high-density layouts, but in many executive/offshore configurations it carries fewer; either way it exceeds the light helicopters. The Enstrom 480B and Robinson R66 are much smaller, typically accommodating about 4–5 people including the pilot.
