Robinson R44 Raven II

Overview

• With decent cruise speeds, reasonable fuel burn, and straightforward maintenance—even though it is pretty much the only choice for someone wanting a piston, four-place helicopter—the R44 is not a compromise. Assuming you can stomach those costly life-limited parts, you’ll be on your way to building that pad in your backyard and being the envy of suburbanites everywhere.
