Propeller redundancy is a huge deal for UAV pilots flying expensive equipment. Many companies claimed to be able to do this, but most of them can't. To demonstrate propeller, motor and ESC redundancy, we disabled a propeller on the Perimeter 8 Drone while carrying a 5 kg VUX LIDAR from Phoenix Lidar Systems. We then proceeded to yaw the vehicle. This is a very hard maneuver to do with one of your propellers missing. For more information, visit www.skyfront.com
