The two-seat R44 CADET is a versatile helicopter ideally suited for flight schools and operators who want the economy of a small helicopter without sacrificing the power and performance of a large helicopter. The Cadet has the same airframe, rotor system and Lycoming O-540 engine as the proven R44 Raven I. The differences are the Cadet's aft compartment is reconfigured for cargo, the maximum gross weight is reduced to 2200 lb, and the engine power is derated to 210 hp take-off and 185 hp continuous. The lower weight and derated power provide increased performance margins at high altitudes and extend the time between overhauls to 2400 hours. Cadets feature streamlined instrument panels and a crashworthy fuel system.

The R44 FLOAT CADET is equipped with fixed utility floats providing an extra layer of safety for over-water operations. Fixed utility floats remain fully inflated, add approximately 50 pounds to the aircraft’s empty weight, and reduce cruise speed by approximately ten knots.
