Enstrom Helicotper F 28f vs Md Helicopters Md 520n vs Robinson Helicopters R22 Beta Ii

The Enstrom F-28F, MD Helicopters MD 520N, and Robinson R22 Beta II are all light civil helicopters, but they sit in different niches. The Enstrom F-28F is a light piston helicopter typically used for training, patrol, and utility work; it generally carries a pilot plus two passengers (three total) and offers a moderate range for its class, roughly a few hundred miles depending on fuel and conditions. The MD 520N is a light turbine helicopter aimed more at professional missions such as law enforcement, utility, and executive transport; it commonly seats up to five (pilot plus four) and usually provides the longest practical range of the three, again on the order of a few hundred miles with mission-dependent reserves. The Robinson R22 Beta II is a very light piston helicopter optimized for affordability and primary training; it carries two (pilot plus one) and typically has the shortest range among the three, though still suitable for local and regional flights.
