Which multirotor configuration uses vectored thrust to control yaw axis?

• A. Quadrotor
• B. Hexacopter
• C. Y6
• D. The Tricopter

Answer: (D)

The ability to control yaw with vectored thrust comes from tilting one rotor’s thrust so its force has a horizontal component that creates a yaw moment. In a tricopter, the rear motor sits on a servo that can tilt side to side. By tilting that rotor, its thrust vector is redirected, producing a sideways push that makes the aircraft rotate around the vertical axis without needing to rely on torque differences from all rotors. The other two motors stay mounted with vertical thrust, so the yaw motion is driven by the angled thrust of that single tiltable rotor. Other configurations keep all propellers vertically oriented and manage yaw by changing the relative speeds of the rotors, which changes drag and reaction torque but does not vectord the thrust itself. So the tricopter is the one that uses vectored thrust to control yaw.
