2DOF Seat Mover QS-H13 Challenger sets a new benchmark in the world of motion systems for those seeking a compact and ultra-quiet solution for their driving or flight simulator. The Qubic System seat mover – QS-H13, built using the same advanced technology as the QS-220 actuators, outperforms and challenges all currently available seat mover solutions. By delivering smooth and precise motion across two axes (pitch/roll), it accurately simulates the forces experienced during braking, cornering in a car, or executing sharp maneuvers in an aircraft.
