Yes, indeed, though this seems to be an experimental drone. Most common commercially available DJI drones fall if single motor or propeller fails, though in future they may gain such functionality, which would be great for safety.
A nice example of a different approach is a variable angle of attack propellers which are driven by a single motor [1]. See after 0:52 and 7:13. In case battery is dead since all the propellers are synchronized they auto-rotate and stabilize the drone (near the earth the pilot activates the motor just to land softly, but likely similar effect can be reached by properly adjusting the angle of propellers in proper time, like in case of auto-rotation landing for helicopters).

- mikepurvis 6y agoOh yes, it's for sure an experimental thing, and probably patented out the wazoo. My point is just that it's physically possible, as I don't think that is well known. (Note also that doing this outside of a mocap arena would probably require a pretty high-quality IMU since you need very accurate yaw and you're constantly integrating your gyro to get it, with only the magnetometer and maybe the camera providing any kind of absolute reference.)
