Bell 525 Relentless vs Daher Tbm 960 vs Enstrom 480b vs Robinson R66

The Bell 525 Relentless is a large, twin‑engine helicopter aimed at offshore, corporate, and utility missions. It carries the most people of the group, typically accommodating around 16 passengers depending on configuration, and offers long helicopter range (roughly in the 500–600+ nautical mile class) with higher cruise speeds than smaller rotorcraft. The Enstrom 480B is a light, single‑engine piston helicopter primarily for training, patrol, and personal/utility use; it typically seats about 4–5 occupants and has comparatively short range, commonly around 200–300 nautical miles depending on fuel and payload. The Robinson R66 is a light, single‑engine turbine helicopter for private, touring, and light utility work; it typically carries about 4–5 occupants and generally flies farther than the 480B, often around 300–350 nautical miles. The Daher TBM 960 is not a helicopter but a high‑performance single‑engine turboprop airplane; it typically seats 4–6 and delivers the longest range of the four, commonly around 1,500+ nautical miles, making it the best fit for fast, long cross‑country travel.
