A coaxial rotor pair assembly, e.g., for a flight vehicle or drone, with a fixed-pitch rotor and a variable-pitch rotor that are axially spaced relative to one another on a rotor axis for rotation via rotor shafts. A first motor and a second motor are provided for the rotors to drive the respective rotor about the rotor axis. The first and second motors are each controlled by a speed controller, and speed controllers are controlled by a vehicle flight controller. A collective pitch of the plurality of blades of the variable-pitch rotor is configured to be selectively varied by the vehicle flight controller during rotation of both the fixed-pitch rotor and the variable-pitch rotor about the rotor axis. The plurality of blades of the fixed-pitch rotor are maintained a constant, fixed pitch, e.g., during operation of the flight vehicle.
