 Like other Kamov helicopters, it features Kamov's characteristic coaxial contra-rotating rotor system, which removes the need for the entire tail rotor assembly and improves the aircraft's aerobatic qualities—it can perform loops, rolls and "the funnel" (circle-strafing), where the aircraft maintains a line-of-sight to the target while flying circles of varying altitude, elevation and airspeed around it.The omission of the tail rotor is a qualitative advantage, because the torque-countering tail rotor can use up to 30% of engine power.The Ka-50's entire transmission presents a comparatively small target to ground fire.
