How do you control a drone designed to spin itself at over 250 RPM, and how in the world does this allow for it to maintain stable flight with 2 dead motors? In this video, we answer just that with some unique flight control methods on this tip-jet tricopter VTOL.

I’ve been working on this tri-mode VTOL drone for a while now, and it was finally time to tackle the toughest problem yet: directional control while in the efficient spinning mode. In the first video, we demonstrated the efficiency gains of turning itself into a huge prop-driven propeller, and in the second video, we showed its fast forward flight capabilities. Not only do we now have excellent control while it’s spinning, but I also discovered a secondary benefit of implementing high frequency periodic control. This drone now has the unique ability to lose not one, but two motors in flight and still maintain the complete ability to fly and maneuver around for a safe landing. Seeing how well this actually worked has given me plenty of ideas for future projects, so be sure to subscribe so you don’t miss them!
