Bell 525 Relentless vs Md Helicopters (mcdonnell Douglas) 902 Explorer vs Robinson R66

The Bell 525 Relentless is a larger, modern fly-by-wire super‑medium helicopter aimed at offshore, corporate, and utility missions; it typically offers the greatest range of the three and the highest passenger capacity, commonly configured around 16 passengers (with variations by layout). The MD Helicopters (McDonnell Douglas) 902 Explorer is a lighter twin‑engine helicopter geared toward law enforcement, EMS, and general utility work; it generally carries fewer passengers than the 525 but more than the R66, typically accommodating about 7–8 occupants depending on interior configuration, with a moderate range. The Robinson R66 is a smaller, single‑engine turbine helicopter designed for private, training, and light commercial roles; it has the lowest passenger capacity, usually seating 4–5 including the pilot, and its range is typically the shortest of the three, though still adequate for regional trips. Overall, the 525 leads on capability, the 902 balances utility and size, and the R66 prioritizes simplicity and operating cost.
