What does the rudder control in a multirotor?

The rudder in a multirotor is primarily responsible for controlling yaw, which refers to the rotation of the aircraft around its vertical axis. When the rudder is adjusted, it influences how the multirotor turns left or right in flight, allowing for responsive maneuverability. By changing the yaw, the pilot can manage the orientation of the multirotor, which is crucial for tasks such as navigating around obstacles or capturing specific angles during aerial photography or videography.

While altitude and speed play significant roles in the operation of a multirotor, they are controlled by other mechanisms and inputs, such as the throttle and pitch, rather than the rudder. Similarly, while direction may seem closely related to yaw, it is the specific aspect of rotational movement that the rudder effectively manages. Thus, understanding the rudder's function in controlling yaw is essential for effective multirotor operation and navigation.
