[edit] Development
This helicopter uses the functional principles of the Flettner Fl 282 Kolibri developed in Germany during WWII by Anton Flettner who joined the company Kaman after the war (Operation Paperclip).
The K-1200 K-MAX "aerial truck" is the world's first helicopter specifically designed, tested and certified for repetitive external lift operations and vertical reference flight, an important feature for external load work. The aircraft's narrow profile gives the pilot an unprecedented view of the load looking out either side of the aircraft.
The K-MAX is based on Kaman's unique intermeshing rotor technology with servo-flap control. The aircraft has counter-rotating main rotors and no tail rotor, which allows all engine power to go directly to the main rotors for the highest lifting efficiency of any rotor configuration.
