Md Helicopters Md 600n vs Robinson Helicopters R22 Beta Ii vs Robinson Helicopters R44 Raven I vs Robinson Helicopters R66 vs Schweizer Rsg 300c vs Schweizer Rsg 300cbi vs Schweizer Rsg 333
By category, the MD Helicopters MD 600N is a light turbine utility helicopter suited to commercial work and higher-altitude operations, while the Robinson R66 is also a light turbine helicopter positioned as a step up from piston trainers into faster, longer-range personal and light commercial use. The Robinson R22 Beta II is a light two-seat piston helicopter primarily used for training and low-cost private flying. The Robinson R44 Raven I is a light four-seat piston helicopter commonly used for personal transport, basic utility, and training. The Schweizer RSG 300C and 300CBi are light two-seat piston helicopters strongly associated with flight training; the 300CBi is the fuel-injected evolution of the 300C. For range, the MD 600N and R66 generally offer the longest legs in this group, with the R44 typically next, and the R22 and Schweizer 300 variants usually shorter-range trainers, depending on tanks and power settings. For passenger capacity, the MD 600N typically carries a pilot plus up to five passengers, the R66 a pilot plus four, the R44 a pilot plus three, and the R22 and both Schweizer 300 models a pilot plus one.
