This is a really interesting build. But I wonder if the final result is a device that is neither a great quad nor a great wing. Given the amount of time it spends as a wing, and that you use a camera switch (rather than gimbal), why not just build it as a twin rotor wing with VTOL capability? You could place the 2nd (liftoff) camera at a 45° downward angle (with respect to wing) for takeoff and landing (or if you want to float around at slow speed). There is so much drag when the wings are vertical, there is little benefit to having rotors forward and aft anyway - I am guessing you can get good pitch authority just with props blowing on the elevons.

Peter, you may want to delete the link, since the miniqbit domain is no longer active and could get hijacked.

Thanks buddy for drop this video,that's huge benefit for me🥰

We fckn love it bruh!

Can you share your Onshape design to me? I would like to make a copy and improve a few things before trying it.

would be interesting to have a more dynamic approach where the drone will check if there is a drone in the area with a similar flight path. Both drones would need to ad hoc decide if the path adjustments would be worth to fly together. This would have the effect that there could be multiple rendezvous and breakup points per flight. For this I'd write the algo in a way that every 'plane' would build the optimal path along some nodes and whenever there is a 'plane' nearby the middle path of both will be calculated and compared against the optimal path. This could be done in a loop for N waypoints (N < remaining nodes in flight path) to generate the optimal path.

can you do a tutorial of the wiring? how did you not use any pins for the drehmflight boards? 😍

I am interested this drone

I need to know more about formation flight path. How to keep distance between them to avoid collision by having single path in between goal and start state. can you share code? implementation

Why did you stop selling it?

Ahh the i term thing...thanks so much!

does the foam board help flight time without any camber? It's kind of interesting, wonder why all drones aren't just like that then.

What wing setup would allow for max speed? Monoplane in the middle? And shape?

Overall, have all of your crashes been due to pilot error or some of it due to the drone design? If yes to latter, what are the limitations or maneuvers to avoid

Very interesting idea! I was super curious to see Joshua’s review, but unfortunately it’s not available (UA-cam says it’s private). Does anyone know how to get access to it?

If I may... you should always have a Victorinox (wrongly named Swiss Army Knife) on you 🙂

Sorry to Tell You I built This 15 years ago.

4:34 How is the Music Artist Please?

well done mate!

Looking forward for next improvement

Great! which Autopilot did you use for it? And Did you design the whole model at Simulink then upload the generated code on a microcontroller board or you used a build-in configuration?

The downwash flow of the propeller is quite different from the upcoming flow , I don’t think it’s necessary to change the incident angle if the wing is hiding behind the downwash disks of the propellers.

Hi, great video! Is this script available anywhere for download and use with in own projects?

Very informative and professional video! Thanks for sharing.

Great Job! Thanks for sharing this video. I'm looking forward to seeing more contents from you.

i wanna buy this,,please give me link

Hey, this is awesome! I'm building a similar RC model. Can you please share the 3D Printing files in stl format? Thank you!

Wow! Nice job doing all that. Not sure, though, why you talk about the importance of building a scaled down version of the concept as if it were a new idea. All evtol companies do that.

A fascinating problem to explore. There are many details to consider when comes to real world application. For example with actual aircraft the flight path lengths will vary from the ground path lengths due to wind. Flying into a headwind will make effective flight paths longer, vs shorter (time) for paths that align with the wind. Other details like how the additional aircraft are position relative to the first can vary based on speed and design and weight of an aircraft. No complaints, just realizing the real world complexity. Love the visualizations and the detailed explanations.

Lovely visualization, great video. One critique: I'm not sure your using RRT* effectively. The first pass, which seems to be the regular RRT* seems to have no affect. I'm not sure if I've missed something, but after the first pass you seem to only retain the points/nodes, and rerun RRT* again with a different setting. I assume you could just select nodes at random, without any pathing calculations, and run the second pass. As for the second pass, the configuration seems a bit suspicious to me. Since you don't limit the search radius, doesn't this degenerate the RRT* to a more basic search algorithm? I'm not an expert in pathing algorithms though, I'm sure I missed some important points. Correcting my ignorance would be most welcomed.

Did you also make the amount of cost saving change depending on the amount of aircraft in formation? What if the aircraft take off at different times ? What other applications do you have in mind? I’m a robotics engineer with MSc in drone design, my dissertation is about unmanaged, unmanned battery swapping landing platforms for vtol UAVs. What if you have “refuel stations” spread across the region?

Lot of work, nice video, superb theory...built on sand. The position where to fly in close formation is difficult to find, will vary with speed and altitude and in addition, this will increase collision risk. And your figure, gain of 50 or 70% of fuel is far from being demonstrated. Even if the starting point (economy of energy) has still to be demonstrated and quantified by real measurement, nice 👍 job.

I assume the leading bird expends more energy then the trailing birds. But is there an understanding on birds energy expenditures between leading bird and last bird?

Based on your previous videos, id suggest using ROS2 + PX4 instead of Ardupilot to code this. It's a bit steeper of a learning curve but its way better maintained than Ardupilot so you will have less headaches!

Did both drones get the 30% benefit or only n-1 of a set of n flying together as the leader doesn't get any benefit. The omniscient algorithm then has to direct per the greater good rather than individuals coordinating for personal gain (game theory stuff). Cycling leaders may affect the willingness to coordinate though. Very interesting idea!!!

How you try the Google wing drone

But, do you know why bird formations are sometimes asymmetric?

Buying a higher quality microphone is one of the best, easiest investments you can make

As always, this is great work and fantastic, clear technical communication 👍🏻

since you allow for longer distance travelled to increase efficiency, aren't there some other options that should be considered for more optimal routing ? (realizing that complexity might explode). The thoughts below revolve around scenarios where a formation flight might have occurred but for slight mismatch in timing when passing over a possible randevou point. This can be ""corrected"" by a) varying speed - drone (a) should slow down, so the drone (b) can catchup with it b) delayed or staggered departure - drone (a) should take off slightly after (b) so they coincide at the right point and time

I see this becoming a thing with kamikaze drones flying in flocks to increase the loiter time and have them break off as needed.

This was fascinating. You should explore what happens when the efficiency increases as a function of how many drones are flying together (instead of just fixed at 70%). My rough hypothesis is that when birds fly together, it is a bit like tricking the air to think there's just one bird with a very high aspect ratio wing. So the more birds, the larger the equivalent big-bird aspect ratio, and the higher the collective L/D. Implementing this might motivate the algorithm to prefer formation flying even more.

any suggestion for make a toys?

You are Super Man! and this is Perfect project!

if you're looking for efficiency, one longer wing would work better, esp if inbetween the rotorwash.

why not have a single larger wing beteen the rotors. interaction would be minimised then

@Peter Ryseck Now do a Lilium Jet.

Hiii very cool Can i use pixhawk instead hglrc728?

This gave me an idea: You should be able to use the hotend as normal and just swap out the nozzle for some sort of stiff metal rod like solid copper wire or a small screw, and then use the 3d printer like a sort of router, the foam would just get stuck to the bed with double sided tape or something and you'd cut the foam leaving like 0.4mm at the bottom and you'd finish the rest with a normal box cutter. It could work for making some foam inserts and such.
