A coaxial rotor system includes a plurality of upper rotor blades and a plurality of lower rotor blades disposed at a mast assembly. The upper rotor blades rotate about an axis of rotation in a first direction and the lower rotor blades rotate about the axis of rotation in a second direction opposite the first direction. A control system disposed at the mast assembly between the upper and lower rotor blades includes an upper swashplate connected to the upper rotor blades and a lower swashplate connected to the lower rotor blades. The control system adjusts the upper swashplate and the lower swashplate relative to the mast assembly to adjust respective pitches of the upper and lower rotor blades relative to the axis of rotation. The control system is operable to adjust the upper swashplate and the lower swashplate relative to the mast assembly independently of one another.
