A method of counteracting a rotor moment of one or more rotors of a concentric dual-rotor helicopter (10) includes sensing angular velocity and angular acceleration of a helicopter during a flight maneuver. The angular velocity and angular acceleration are compared to a set of control parameters and one or more control servos change the cyclic pitch of the one or more rotors (12a,12b) to counteract the rotor moment. A control system for counteracting a rotor moment of one or more rotors (12a,12b) of a concentric dual-rotor helicopter (10) includes one or more sensors configured to sense angular velocity and angular acceleration of a helicopter during a flight maneuver. A computer (42) is operably connected to the one or more sensors (44) and configured to compare sensor data to a set of control parameters. A plurality of control servos change the cyclic pitch of the one or more rotors (12a,12b) to counteract the rotor moment.
