2. This configuration is sometimes referred to as a synchropter.
3. The K-MAX relies on two primary advantages of synchropters over conventional helicopters : The increased efficiency compared to conventional rotor-lift technology; and the synchropter's natural tendency to hover.
4. At the same time, the synchropter is more responsive to pilot control inputs, making it possible to easily swing a load, or to scatter seed, chemicals, or water over a larger area.

All of these configurations use differential cyclic pitch to control movement about the yaw axis, tilting the rotors in opposite directions to cause the aircraft to spin in the direction of the tilted rotors.
9. Of all the commonly used rotor systems-- Sikorsky system ( conventional single-rotor ), NOTAR ( if different from Sikorsky system ), Piasecki system ( tandem rotors ), Kamov system ( coaxial rotors ), and Flettner system ( synchropter ), how do they rank in the order from least stable to most stable ( or if you prefer, from most stable to least stable ) ? talk ) 10 : 56, 29 November 2016 ( UTC)
