Bell 505 Jetranger X vs Enstrom Helicotper 480b G vs Md Helicopters Md 500e vs Md Helicopters Md 520n vs Md Helicopters Md 530f vs Robinson Helicopters R66

All six are light helicopters, but they split between piston and turbine utility. The Bell 505 JetRanger X and Robinson R66 are single‑engine turbines commonly used for training, patrol, and light utility; both typically carry a pilot plus four passengers, with the R66 generally offering the longest practical range in this group and the 505 close behind. The Enstrom 480B‑G is a piston, four‑seat utility/training helicopter (pilot plus three passengers) with a shorter range than the turbines, but valued for stability and load‑lifting in its class. The MD Helicopters MD 500E, MD 520N, and MD 530F are turbine “500‑series” aircraft optimized for agility, high performance, and mission equipment; they commonly seat a pilot plus four passengers, though mission kits can reduce usable seats. In range terms, the MD 530F is often among the stronger performers, especially in hot‑and‑high conditions, while the MD 500E and 520N are broadly comparable and typically trail the longest‑range R66. The MD 520N stands out for its NOTAR anti‑torque system rather than capacity or range.
