если я не прав то поправьте меня но по моему в синхроптерах управление осуществляют с помощью закрылков на концах лопастей а не с помощью автомата перекоса , там система другая вот описание на инглиш .
On most helicopters the controls are connected to a big swash plate underneath each rotor which can rotate the entire blade (changing its pitch angle) throughout each revolution of the rotor. On the K-max the rotor blade angle is fixed at the root of the blade, and control linkage runs up through a very small swash under the hub then linkage continues inside the blades out to the servo flaps. They work similarly to elevator and rudder trim tabs. When the flap goes up, the rear of the blade goes down, increasing the overall angle of attack of the blade and vise versa. But because the rotors are fixed at the root, the blade must twist to accomplish this this. That means the K-max blades are twisting and untwisting with every rotor revolution. Yaw control: on a traditional non-intermeshed tandem rotor helicopter (Chinook) when you want to induce yaw, you can tilt one rotor right and the other left creating a large yaw moment. On a coaxial helicopter (various Kamav) you increase the collective of one rotor and decrease it on the other. The rotor producing more lift produces a greater torque reaction and the aircraft rotates the opposite direction while net lift produces is about the same. The K-maxx does both of these at once. It increases the collective of one rotor and decreases the other, while also tilting one rotor forward and the other back with differential cyclic inputs. All of this is handled with mechanical linkages, with no hydraulics.
