A fixed wing drone needs at least one extra motor for the control surfaces. More likely two or three.

This design still requires an additional servo for rotor actuation, so the minimum number of actuators is the same as for a fixed wing (roll and yaw are coupled, so the bare minimum is a single rudder servo).

  • No, the rotors are tilted by timing the acceleration from the single motor - there's no servo in the design in the video.
