Turning on the spot

Breaking the balance on purpose

To turn left on the spot without tilting, the drone spins the clockwise pair harder, to about 110%, and the counterclockwise pair softer, to about 90%. The balance from Chapter 2 breaks, and the body turns counterclockwise, to the left. The total push stays the same, so the height does not change.

Why?The faster clockwise propellers twist the body counterclockwise harder than the other pair twists it back. The two faster propellers sit on opposite corners, so the drone does not tip forward, backward or sideways.

Go furtherThe twist from the propellers is much weaker than their upward push. That makes turning on the spot the slowest move a drone can make. This drone was set to turn about 84° per second. Turning on the spot is called yaw.
