Well it does, but is counteracted by directed airflow with an axial component. You can see the craft yerk around the axis when the torque changes due to changed RPM of the fan.

@tesla500

Thanks! There are static vanes in the duct that straighten the airflow out, so there's no torque produced due to the airflow or fan spinning. The inertia of the fan does cause torque when spooling up or down, which the thrust vectoring vanes compensate for quite well as long as there's power applied. At low throttle, it can spin around quite a lot, but if you punch it above about half throttle, it stays in position quite well.

Really cool project. Seems like landing it is one of the challenges at this point. Seems top heavy, but also the thrust is causing a turbulent ground effect. In the redesign of the frame you might consider having longer landing gear support the frame from the top for a wider, more stable landing surface. The legs could also be usefully designed as strakes for flight stability if you get into horizontal high speed flight. Hope to see more on this project!

I still remember the time when I built a plane with nicad cells and a brushed motor and it was just barely able to climb. Brushless motors and lithium batteries are quite something, combined with the electronics to keep them from plowing straight into the ground. The design challenges are very different now, but certainly no easier.

@coriscotupi

+stefantrethan I still have an electric powered glider by Kyosho that I bought about a quarter of a century ago. It was powered by a massive, brushed motor and a 10-pack Ni-Cd battery that added a ton to the sailplane. It barely climbed to altitude, then sank like a brick, and then did one more climb and that was it. Fast-forward to the 21st century, I replaced the motor with a much more powerful brushless one and a much lighter and more powerful LiPo battery. The glider now reaches altitude in about 30 seconds, easily glides tens of minutes at a time, can climb to altitude dozens of times in a single charge. I can literally get a whole flying day out of one single battery charge. Electric powered gliders of the 90s were ahead of their time! It is only now that even 25 year old designs reached their full potential.

Ok that was cool, I've done RC cars, helicopters, quad copters, hex copters. Each have their own challenges but this concept is just cool.

I've had a 90mm EDF sitting in my office for the last 6 months to do exactly this :-). Great work with coupling the autopilot to the pitch rate to compensate for precession.

Dude, you need to cool your fucking jets. (or ducted fans in this case). There are considerable differences between the design of this drone and the T-Hawk (which you refused to even name as the infringed design yourself). The control surfaces are completely different (and innovative) as well as the internal ducting. And you seem to completely ignore his work modifying the software (which also has NO connection to your beloved military craft). The fact is that ducted, single rotor, thrust vectored, VTOL aircraft have been developed since at least the 1950s. See: the Hiller 1031-A-1 and the Willams X-Jet and WASP. airandspace.si.edu/collection-objects/hiller-model-1031-1-flying-platform hyperboreanvibrations.blogspot.com/2011/03/williams-international-x-jet-and-other.html You really don't seem to understand how IP and patents work. This man has done a lot of hard work to make something that functions and you are shitting all over his contribution to aerospace engineering. He didn't "steal" anything. He designed his ducting himself and the geometry of the fins and cutouts alone would be enough to patent his design, but he chose to share it with everyone instead. You need to step off your high-horse and show some respect for a guy that put a lot of love and effort into something so that we could all enjoy it and keep building on the idea.

Holy flying fans batman!

He was actually wrong about something though, the phase delay of helicopter control inputs aren't gyroscopic precession it is an aerodynamic effect caused by blade being unable to exert pitch and roll on the airframe instantly the same as moving the elevators and ailerons on an airplane can't instantly pitch or roll the aircraft (a helicopter rotor is literally a rotating wing) The phase delay is (usually) close to 90 degrees, but not exactly 90 degrees and in some designs it's quite a bit off like with the Robinson R22 which has a phase delay of 70 degrees or the Sikorsky prototype I read about that had a phase delay of almost 100 degrees. (basically the lighter and stiffer the rotor the less delay and the heavier or more flexible the rotor the greater the delay). Gyroscopic presession is always EXACTLY 90 degrees so for phase delay to not be exactly 90 degrees in helicopters disproves the presession myth right off the bat. (helicopter rotors rotate too slowly and and don't have enough mass for gyroscopic presession to have a significant effect)

I would give up much faster I would have NO WAY THOUGHT YOU COULD STABILISE THAT THING WITH ANYTHING SHORT OF MACHINE LEARNING I woulcn't have thought that just applying a simple correction to the code that you get out by using the gyroscopic precession equasions would work, because turbulence and inertial instability and positive feedback loops and angular momentum in a closed system etc, etc JUST SEEING you tweak that one line of code, doing the exact correction the theoretical model tells you and achieving the stability sen at 16:07 SEEMED LIKE MAGIC TO ME like, idk how to describe this but ... YOU MEAN PHYSICS JUST WORKS ? in an IMPERFECT WORLD ? That feeling was nothing short of hope ACTUAL HOPE because even though the world is imperfect, by understanding it you can "negociate" with it JUST ENOUGH SO THAT YOUR THING WORKS this was beautiful

You have built an exquisite flying machine In retrospective, it's so much more interresting than if you just had a co-axial EDF instead

Man do a kickstarter, get this things bugs worked out and built then distributed! It would be the next best drone or hobby flying aircraft!

No, this is a cool engineering challenge. As a drone, it's even more inefficent than the ones we have now.

I was thinking that - but I think noise could be a big problem (I noticed he's got ear-protection on... in the car port I guess) Love the project though! Makes me wanna get stuck into something...

Slow-motion camera is absolutely awesome this thing is spectacular well done🌹

I am working on a very similar project for my capstone project. I would suggest looking into adding stationary blades at the outlet of the duct to counteract the torque effect. Honeywell built a drone similar to this and that is their method of counteracting most of the torque effect so the outlet veins don't have to stabilize as much. It should put less stress on your outlet veins and make stability easier in theory.
