- This video was so much fun to make. I can't believe what the swing wing is capable of. I really wasn't even sure what to title this video because I had so many good ones in mind. Its an RC sky diver, its an RC wing suit, its an RC space shuttle! it really blew my mind and I hope you guys can help me figure out why it flys so good like this.

Too bad you never sold a kit so people can buy and make this from you
You can thank your parents for supporting you with such enthusiasm. Bravo to them for encouraging your imagination and your entrepreneurial spirit, it's such a change from these parents who resign from their responsibilities and let their children vegetate in the magma of social networks
It's tough for us that grew up poor to realize our creativity was no different, just less capital to realize our dreams.

A glider instructor once told me:
"Now THIS is flying, everything else is just getting dragged through the air by an engine [or two]".
Super cool that you accidentally ended up with a lifting body with an utterly extreme variable sweep wing. Gives lots of options for high speed and low speed flight. A rebuild with a focus on this newly discovered capability would be really neat to see.
It's time to optimize the wing shape to resemble a narrow wing profile when folded.
Put the wing pivot points behind a streamlined center section to keep maximum slipstream effectiveness.
Add in additional roll servos that switch into action when folded. (Mini servos, mini alerons) A limit switch when folded would switch the wires from folded to unfolded servos and vice versa so nothing changes for the pilot to control roll movement and no additional channels needed on the radio.
Also possible to mount the battery on a sliding tray that is coupled to the folding function. This would provide a way to use the battery movement during folding for maintaining the correct center of gravity in open or folded flight positions.
make a ''wind tunnel test'', a tube, a fan, and some glued threads on the spots... there's airflow, between the boat and the folded wings... and at high speeds it gains speed, saving power [less friction] you only need wings unfolded to maneuver, slow down, land and take off... the slow stuff...
With enough thrust everything can fly. 😄
So true
I've heard a helicopter called a triumph of brute force and engineering over the laws of physics and common sense.
Projects like these are great! Exactly the kind of thing schools should be teaching.
Eggggsacktly I agree. The most important teacher in school is the wood shop teacher.
@@eternalprogression I am on an school in Germany where we have woodworking gardening and copper working as lessons and it's pretty cool and a nice Variety from the normal boring lessons.
@user-ke8sf2kp6h oh that is awesome!! Outside of America some places have some really cool schools.
@@eternalprogressionits not like there aren't schools like here, it's just that they are either rare or expensive. I would definitely approve of the sort of stuff being added to the public curriculum though.
This only keeps on getting better.
I think a cool set of experiments would be to eliminate one thing at a time (while keeping track of how the CoM is moving) and seeing what is actually producing the lift. It would be crazy if it was the boat hull all along 😂
To answer why its flying like that its simply thrust factor. It's essentially a Bi-copter when employing the rotors to full power. That's why you're sustaining flight. The rotors take over and the body of your aircraft is just there for the ride. Great work! Keep it up
How nice, 👍👍👍👍
Lift I think comes from the fuselage, really any shape at the right angle generates lift, it just might not be the most efficient profile.
I have a glider plane that I launch from another plane, which is literally an almost square box and has a 2 to 1 glide ratio, without an engine.
You could put some servos in the fuselage with small fins directly attached to the servo arm and have aileron control when the wings are folded.
Love to hear the excitement in your voices…you are creating some amazing memories with your dad!
This is an amazing project!
I would love to see swing wings in the Flite Test shop.
Twisting wire does help with some kinds of interference due to long straight wires acting like antennas. This is why phone wire and cat5/6 is twisted-pair.
that's only half true, every length of wire acts as an antenna, the length determines how good of an antenna it is for which frequency (wavelength). The twisting keeps the wires as close as possible, this helps to reduce interference, because these wires carry information via the difference in their potential. When there's electromagnetic interference, it acts on both of the wire at the same time, meaning the differential is not affected by the interference. Hope this explanation was more or less understandable 😅
You are my inspiration
Love the flying boat swing wing design it’s so cool! I used to design and build large model-scale aircraft for competitions in college. Some others have said that the folded wings act as a single wing and that’s correct, and with that much thrust from the motors you can get away with reducing the surface area by quite a bit and still fly. At these speeds and weights the airfoil shape isn’t as important.
Your videos are awesome man. You’re a great engineer too. Keep it up
Thanks man!
Awesome that it flies with the wings swept in! I'd love to have one of these in my Hangar!
Dude you're seriously one of a kind! Totally amazing design! Makes me want to design something!
Thx man!
If you could move the cg back when the wings fold such as sliding the battery for example, it might be more controllable. In any case well done great idea.
Love the HOME song. Though we were watching SummoningSalt for a second lol
Hahaha I love summoning salt. I have to give him credit for the amazing songs in my video. Not only his main song but I wouldn’t know abt HOME if it wasn’t for him.
I love your swing wing so much! I'm considering making one with a pivot and a linear servo to retract the wings.
Your Swing Wing videos have inspired me to get into designing rc planes. Keep up the good work!
Awesome man!! You to! Thx
I've always loved lifting bodies and you made one that has fold out wings!
1. Very cool project. 2. Twisted pairs of wires do in fact cancel much (but not all) emf interference. That's why it's a standard practice. especially in low-power systems
there's airflow between the boat, and the folded wings... even the new tail gives some lift...
Yes, twisting pairs does help with interference - just look at Ethernet cables for example, 4 twisted pairs within a cable, some for data, some for power.
Patent this beautiful design.
Big fan
Awsome video. Great design. I would love to build one of these. If you had different sweep stop positions you would be able to get a larger speed envelope. Something like 50% 80% and then 100% sweep would be great fun.
This such a cool video! also twisting the wires does help 🙃
Yes I want one ! AWESOME !
Such a cool design!
I Enjoy your Joy!
I wonder if you set a stop for the wings in a semi-closed position can you gain a bit more attitude control and lift. You might even still have some aileron control. Perhaps having it in a more swept-wing configuration is preferable to fully collapsed, but have a sort of "Dive" button to instantly collapse the wings at will. Maybe it could afford even more agility when doing acrobatics.
Oh, and as for the lifting body question: it's extremely similar to the offset wing question. You have flat bottoms on all of your surfaces, which acts as a single lifting body, even though they are separate. It's the cumulative force on the body, not the individual force.
That's some awesome flying m8
Bro you are the best
Loving the stuff you're making!
Thx man!
another awesome video buddy! keep it up!
Thx man!
I bet you can use this as a stepping stone to making a Lifting body, or blended wing / body design. 👍
You have a cool dad!
First. Just here to give you the view. Everyone should go to your patron
Haha hey Kent, thx man
I believe it is because it has a huge elevator and plenty of thrust from the two motors.
making a swing-wing plane with internal wings should be the next project
Great video!!!🔥 Love the fpv cam view👌
You’re an artist in the UA-cam community, amazing video
Edit: You made a plane with no wings!
Thx man!!!
dude made a real life third person view amazing
1:26 twisting the wires is normally use to keep it more compact
I have really enjoyed watching your journey on here since Flite Fest this year. Look into the history of the lifting body X-planes that were part of the pre-space shuttle development. I think you'll find a lot of cool stuff. Also, if you're going to fly with the wings folded, or even just to simplify the build, you may consider changing over to tailerons/elevons (split, independent elevator surfaces for both elevator and aileron control). Good stuff man, keep it up!
MORE POWER!... IT NEEDS MORE SPEED, to fly like that... and unfold the wings for the slow parts... AND PATENT IT!... before they steal it!
Wow! Another amazing video as usual! I know there are lifting body planes, I think the dream chaser spacecraft is meant to glide back to the earth without real wings by just using the fuselage as its wing, but its really fascinating that your's flies so well! Keep it up!
Your parents are the best!
hey bro! a hug from Brazil, I love your content. Keep doing this awesome crazy things hahahaha
Thx man!!!
Excellent works. Digging the enthusiasm. I found on the one like this that I built, that placing weights on the rear of the wingtips helps keep the plane flyable and from diving due to shift in the cg location when the wings are swung back.
Absolutely amazing. Also have you considered testing the wing swing to have different angles of sweep like the tomcat. Also it might help if you turned the elevator into a elevon control
Great video and project. The plane does many strange things that a plane doesn't normally do. And I love it 😄. I think the reason why it flies with the wings folder in. Is that it's basically still just a wing. Narrow but long. That's why it gets more unstable. It is like the F14 Tomcat. Maybe try to make a curved edge on the body end of the wing. So when the wings are folded in. The leading edge is still a lift-generating surface. and not a blunt surface. That might make more lift and stability.
damn bro nice discovery
i love your channel and you deserve 1 mil subs, hpoefully 20k subs by end of 2023, ive been subbed when you had 2k subs
This was so cool I had to watch it again 😁
We need you to get somebody to chase you and film you with a drone with the wings folded back!
I dooooooo!!! So bad
@@eternalprogression You need to ask on your next video
@mikeehuber ya I should. Maybe I’ll also ask on instagram.
This is awesome
It seems like the fuse with wings retracted still has an airfoil shape, and you still have a good fraction of the overall wing area.
Twisted wire pairs definitely helps unless you are trying to pick up or radiate EM waves of some kind. So don't make a twisted pair antenna, but for everything else it is probably going to help. One limitation is that it will slightly increase capacitance. If your signal is getting into the GHZ range you either need to stick with engineered solutions or conduct your own tests. Twisting the leads to a motor can reduce EM noise from your motor controller, and that might get you slightly longer range, but probably not as much as better antennas would.
We need more swing wing full sized jet fighters
There was one. The old german fighter jet tornado.
@@TinMar79 The Panavia Tornado is a great example of swing-wing fighter jets along with the F-111 Aardvark, F-14 Tomcat, MiG-23, and Su-23. It's truly a shame that the era of variable-sweep wings is over.
The F14 Tomcat is next.
Lift..
The elevator? There is alot of surface area...perhaps some lift from the motors if the angle of attack is just right and then you have a boat shape at the front that may be pushing the nose up as well.
Nasa did some testing with lifting bidies. You could find some video's on UA-cam.
Congratulations on your build.
Man ever since I saw you’re video on the controller ur working on. I am just so happy that I found ur channel I love these kinds videos
So how many defense contractors have tried to recruit you? This is so damn cool!!
That's so cool
So good, would love to see some gps speed telemetry to see how much faster it flies in folded config
Oooo yaaaaa good idea! I’ll look into getting one.
Twisting the wire eliminates the interference. I experienced this first had with a four engine bomber with a wingspan of 55 inches. Each motor had its own speed control. Needless to say I had a lot of wires and a lot of current. The symptoms I was having was intermittent severe fluttering of my elevator and ailerons. When I twisted the wire, the problem disappeared.
An example of this could be like the flying pancake
You should try landing and/or taking off with the wings closed. I would totally build and fly this thing!😁
There are two theories about lift, the simple one is angle of attack, which is how a nutball flies. With an airfoil, the idea is that the air on top is moving slower than the air on the bottom which creates suction that pulls it up. I think all the drag on the top and smooth surface on the bottom are actually acting like an airfoil.
The wings still produce lift when folded back, it’s just moving the center of lift back really far, which makes it’s stall speed much higher while making it more stable and make less drag. The center of mass moves back as well but not as much as the wings. The craft still makes just as much lift, just the center of lift is moved back
Awesome 🔥
Body lift is a thing. Look at some of the early super sonic planes and some of the wild concepts in the early days of aviation. Even the Piaggio p180 produces a significant amount of lift with just the body of the plane.
You might also try breaking your elevator out into 2 control surfaces with seperate servos. Then setup mixing in the radio so when in folded mode you have some roll control moving the elevators separately and together as an elevator.
Yes twisting wires does help with interference
Would be cool if you made a version where you can fold both wings individually and where you can unfold them only half or so. Most radios have these potentiometers. Would be cool if you hook them up to the fold angle of each wing.
I would def buy this as a kit. @FliteTest
Yay thx for the comment!!
I really think you should sell kits or at least plans for your beautiful design. Also put links for the stuff you added on to the original design to give it First person vision capability. Congrats on a great design!+

@@eternalprogression
You made a lifting body!
This is an absolutely awesome build, plus it changes the 'gameplay' of the flight itself. Would love to see a kit for it or at the very least, downloadable instructions to source and put it together (I'd buy that) xD As for why it flies well with the wings closed, you're creating lift with the front props plus it seems like it's really light so it kind of makes sense. The pointed diamond shape it has probably contributes, basically makes it like a kite with thrust? I'd suspect if the center of the wing was widened too much it'd probably flip over, or if it was too thin it'd sink more due to less lift. Would be cool to see some variants with different wing thicknesses or maybe a smoke test to see the airflow :D
I see many applications for a control scheme like this. It would provide an ideal mix of payload capacity, control and efficiently for loitering munitions.
When you retract the wings inward, it reduces the aspect ratio to something like 0.5:1. That causes a giant increase in drag which makes the airplane sink much faster to the ground. But it also makes it so the wings don't stall as easily, giving you great control over the pitch angle, allowing the motors to do the lifting.
Hope this explanation offers some insight! 🙂
You could try pinching together the fuselage adjacent edges of the wings which seem to be hidden while the wings are deployed but are leading when the wings are folded. Perhaps that would reduce drag and increase lift while in the folded position.
Merry Christmas 🎄⛄ Hope you and your family have a great new year 🎊 God bless 🙏🏻
Hey thanks so much!! Merry Christmas and happy new year to you as well🎄 I really hope you had a good one!
This is so sick dude, i love the fpv system !!! I'm wondering how fast it goes, could you maybe add a gps of some sort?
Ya I’m gonna have to get one to find out!
I would buy this if you made it into a diy package on your store
I would like to see you fly one without wings fitted and see if the hull and tail plane would give you enough lift to fly but great vid all the best from Scotland
Excellent! My very non-expert theory is that the body and tail are enough of an aerofoil for it to glide like the shuttle and the thrust from the props is enough to cancel out the sink. Whatever is happening it is cool and I am enjoying following along. :)
If you laser cut these and make them available I would be ecstatic. I have had a pix hawk sitting on the shelf for 6 months not being able to decide to make a drone plane boat or sub. I think this would be fun to try autonomous flight catching thermals and see if you could dart between them to travel long distances.
Awesome video! Btw awnser to your question, does twisting wires work? Awnser is yes as long as you twist tightly enough and have a active ground wire in there then it will shield somewhat
Cool project
Could you fly it like a peregrine falcon? That would be awesome to see. Great Video, had me smiling as well as you flying it!
How about a flying model of a wing suit where the "arms" are your retracting mechanism
Liked and commented just hoping to give your channel a push it deserves.
Thanks man!
🤯🤯
You don't need wings, or a tail. It can hover by it's propellers. But then it would become a tail sitter VTOL. Since you have differential thrust you can get away with one servo for pitch. Have you considered coaxial propellers?
I am working on something similar.
I mean, technically, it's just switching from something high aspect ratio to something low aspect ratio.
You've built a weird variant of the Northrop Switchblade.
