What multirotor configuration uses vectored thrust to control the yaw axis?

• A. Quadcopter
• B. Hexacopter
• C. Octocopter
• D. Tricopter

Answer: (D)

Yaw control with vectored thrust means changing the direction of thrust to create a turning moment around the vertical axis. The tricopter does this by using one motor mounted on a hinge or servo so its thrust vector can be tilted side to side. When that motor tilts, the horizontal component of its thrust produces a yaw moment, causing the craft to rotate about the vertical axis. The other common multirotors—quadcopter, hexacopter, and octocopter—typically control yaw by adjusting the speeds of their rotors to generate differential reaction torques, rather than steering the thrust direction. So the ability to steer thrust direction to achieve yaw is what makes the tricopter the configuration that uses vectored thrust for yaw control.
