- Hey all! I really do appreciate everyone watching, thank you! In today's video we're exploring the physics behind the mono-wing. I started by 3D printing wing sections that was glued in order to complete an entire wing. However, it proved to be too heavy. I made a new wing out of depron foam which worked a lot better. The best way to support the channel is to simply watch my video, thanks guys!

Your English is just fine. Certainly beats the hell out of my Swedish.
Same here. The extent of my Swedish after a couple trips to Sweden is "Tak tak". (I don't think that I interacted with any native Swedes that didn't speak English...)
My Swedish is limited to the goods in the Ikea catalog 😂😂
There are people who claim that English is their mother tongue but few understand a single word they say. I understood you perfectly.
@@NimmoJamie A LOT of people speak English less well (or with heavier accents) than this guy does. I can barely hear his accent;
Dude, don't worry too much about your translations. They get the message and details across. Good stuff!
Completely agree
translations are fine
Same here. Love the difference in speech and it doesn't detract from the info at all
100% agree!
Now those "landings" on the other hand... 🤣
That one flight where it skipped off the ground and recovered was my favorite 😅 that thing is terrifying
Imagine enjoying the playground then seeing that thing coming for your head!
Pioneering work for future A380-size boomerangy airliner?😅😅😅
It briefly became a one-bladed lawnmower 🤔
Nice one Simon 😊 So cool to see someone else trying these one winged helicopters! I also based by designs on that original Charybdis design and found the extra stabiliser unnecessary. If the wing has a positive angle of attack, it works just like a flying wing (with no tail). I’ve also found other designs work without the counterweight (again, like a flying wing).
wow
Ello
Now let’s try to find a genius who can give basic directional control. Maybe with some gyro magic? Since it’s rotating an upward force might translate into a pitch or yaw if timed properly?
I have made monocopters with directional control, using a magnetometer (digital compass sensor). A gyro is usually too slow, since most gyros have a maximum measurable angular velocity of 2000 degrees per second, which translates to only 5.6 rotations per second. So unless your monocopter rotates very slowly a gyro can't keep up.
An old Popular mechanics magazine has a design that supposedly works perfectly
You humor is matchless. I don't really care which project you pick, your sense of
comedic rhythm and involvement rivals the all-time greats, like Buster Keaton.
I am a fan!
Agreed!
Those 9:50 minutes until you mentioned the leading edge of the wing was facing the same way as the prop were Excruciating man...I did not see anyone in the comments mentioning it at a glance...I was screaming internally ! And then...FINALLY !
You saved me from 5 minutes of agony
It was painful to watch!
I was in the same state as you were... I simply couldn't understand (unless made on purpose) that fatal error.
I will post it on the general comments but unless the rotating axis is positioned at the beginning of the wing, it won't fly.
Clearly, engineering is not his forte.
Yeah, I saw that, but I just assumed that either a) I was wrong, what the hell do I know about making a mono-wing or b) he spotted the error and fixed it before testing.
Never occurred to me that the real answer was c) he made a boo-boo! 🤣
Anyway, this was fun!
I love that you show the failures along the way, it makes the successes that much sweeter.
The weight on the stick isn't to offset the centre of gravity, but to provide pitch stability of the wing. Without getting too deep into the dynamics, the weight on a stick increases the moment of inertia along the wing spar axis which, once spinning, creates a stabilising gyroscopic force that prevents the wing from pitching.
Yes, and another function is to set the wing's pitch angle (as well as the prop's pitch angle). The weight basically makes the vehicle strongly prefer to align its "plane" perpendicular to the spin axis. At that point, you can set the wing and prop's pitch angle relative to the weight pole.
@@IsaacKuo yep good point
So adding a servo to move the weight stick up and down, could be used to control the wing angle of attack.
when having issues translating, dont be afraid to just say the word or phrase in your native language. Laura Kampf has said "Geil" so often, im sure everyone understands it now
Yeah, just don't say the same word in dutch lol
I like how you said it spins the right way and then you used a left-hand propellor.
See, that's what I'm talkin' about! Like a "master juggler" keeping all the balls in the air
Your English is fine.
When the wing is free to move, the center of gravity is going to be directly below the center of lift; that is just physics. If that orientation of the wing is then such that the thrust vector is not pointing straight down, the wing is going to spiral off at random.
The problem is, the center of lift tends to be halfway down the length of the wing, while the center of lift is much closer to the motor, so the wing will yaw (or bank, depending on how you look at it) severely, trying to get the COG directly below the COL. I don’t see how to overcome this.
His English is better than some of my English friends 😂
It's really untrue that the wing will spiral off if the thrust vector is not pointed straight down.
In fact, it's impossible for the thrust vector to point straight down due to drag. The wing has no propeller to counteract drag, so its thrust vector will always point "backwards" compared to its motion. The propeller is there to prevent drag from slowing down the spin rate, but it's pointed in the opposite direction so this doesn't "straighten" the thrust vector downward. It does the opposite, making the thrust vector even further away from straight down.
Nevertheless, monocopters work and the fact that the thrust vector does not point straight down simply is not a problem. Why not? Because the vehicle is spinning. That means that the thrust vector sweeps out a cone, and the overall effect is an average thrust vector that points straight down.
@@IsaacKuo "monocopter"? Should be “monopter”, one wing.
But drag is resistance to horizontal motion. The monopter is supposed to hover, isn’t it?
Why didn't you stick the pole into the ground to run these first tests so that you didn't have to be in the line of fire 😂
What’s the fun in that😂?
Thats when you would be in the line of fire, anywhere but right below the wing.
Engagement ❤
I've heard native English speakers do worse. No need to worry at all. Besides, sometimes it helps the goofy tone of your videos and makes them that extra bit unique and fun. Thanks for always putting a smile on my face!
Great video! I love how people are rediscovering the .049 models we use to build and fly 50 years ago...
I love how the noise it makes is comically cartoonish, nice work dude!
that's also a wonderful example of doppler effect! so cool!
yes! it reminded me of the old Batman scene transition sound effect!
that or one of the old time sifi radio shows.. maybe "X - 1"? OR the old "lost in space" shows.
it's definitely one of the most hilarious flying contraptions I've seen.
translations are not a problem, the fact that you actually put effort in doing it is really appreciated!
I really enjoyed the translated captions at the end; I thought they were great.
The issue with your English is in your head, I am English born and bred there and a proud member of the UK. I understood your speech very well. What a concept, does one have to be mad to think of it 😁 You have earnt a subscription from me. Thank you very much. What a wild idea.
I'm very surprised at how such a tiny motor could have the power to move such a big wing so fast, that's a lot of torque, considering its length, goes to show how obscenely powerful brushless motors are nowadays lol. Great job.
That thing is nuts! But I gotta admire a guy who admits to his mistakes!
You might be able to lower the weight of the counter balance by placing the battery et al on the other side of the rod, where the counter balance goes.
Next phase, make it possible to steer. Just add a servo to alter the wing/motor angle... (I have no idea what that would do)😁
Love your projects!
The wing piece being heavy is not a setback, it can give momentum and stability like a flywheel, also, the wing is too deep, it needs to be thinner from leading edge to trailing edge, much like a boomerang wing.
Also, the centre of wing gravity is where you could place the battery and receiver giving it more stability as the differences in weight distribution can make the wing fluctuate like a guitar string.
But given the delicate nature of this project in respect to flight characteristics and technical problems in build quality, I think you did a damn good job to get it flying in the 1st place.
So glad you noticed the backwards airfoil that was driving me insane haha
Thanks for the bonus Swedish lessons so cool! Also amazed that it survived those seemingly violent crashes!
I have never been more frightened for an RC hobbyist.
Have you seen his hovercraft? At least the wing on this is PLA/Depron 😅
Am I crazy or is the wing spinning the wrong way? Surely the motor needs to be turned about 180°.
Edit: nevermind. He figured it out @9:32
Your English is better than most people that I come in contact with daily in the Chicago area.
Long-term subscriber here, and it's been awesome watching your progression from informative 3D printer reviews to creating flying deathtraps.
I love that this channel consistently makes things I've never seen or heard about before. You got your like for mental stability from me. These inherently unstable projects must cause more self doubt than a more conventional one, but I really appreciate watching the success and failures of someone learning new things.
loved the video and who the translation wasnt perfect, the vibe trancended language, hilarious video!! 😂
Wow, that '50s flying saucer sound though! Awesome.
9:50 From the start of the video I was screaming at my screen about it!) And also it seems you tilting the motor upwards at the beginning also was incorrect.
Great video!
Haha I had to go thru the comments & see if someone else noticed & then got to that part of the video 😂
Glad to see you added a helmet to your kit. Great job on this project!
I couldn't get over how much your mono-wing sounded like the flying saucers soundtracks in the bad old sci-fi movies of the 50's. It brought back memories.
Good work, keep going, you will suceed!
Your translations are fine. I didn't even expect you to address them because I am pretty sure you got your points across just fine.
Now I want to build one but style it like Cloud's Buster Sword. Because it really looks like some anime weapon.
I loved your video and especially that you are not afraid to show the whole creative process including some mistakes! Kudos!
A Pole understands a Swede speaking English, that means your English is very good.
Very cool content you have.
The final version looked like an anime sword attack. Imagine how terrifying this would be if the wing had a blade on the leading edge.
Always happy and thrilled to see your content!!
Pretty Amazing that you took this from concept to pseudo-flight. No need to make apologies to us who are watching with awe.
95% of people in the UK can't speak a second language and most of them are lousy at speaking English because of the different dialects. Your English is just fine. Great video btw.
honestly, the translation was fine. I didn't realise it and wouldn't have thought to think that you'd translated it all from Swedish until you mentioned it at the end.
There's a very impressive TED talk from 8 years ago, where Raffaello D'Andrea shows a fully maneuverable version of this.
another good video, never disappointed in years. It's this kind of person who one day invented an essential object. Long live RClifeOn
In amateur rocketry, long burn rocket motors are used instead of electric motors for monocopters. They fly very well.
therapist: "a rotating self flying hatchet is not real and can not decapitate you out of nowhere"
someone walking around with headphones and not hearing it coming: ...
I honestly think he is way smarter than he is letting on and is just trolling UA-cam, a 2 second search will show how simple this project would be and how many other people have already done this.
Now your 'wing unit' flies, maybe one on either end of a spar, Chinook style. Or even the 'Osprey'!
(Love the way it deals with 'ground effect' - 'just punch the planet away & keep on going!' : )
You have the CG in two dimensions, now consider the third Z axis. From the current CG, drop a flexible rod with a small weight, and use the aileron control on the controller with a servo to push that weight in the direction that keeps the wing horizontal, until you want to tweak it to make a change of direction.
I'm not a english native but I understand everything u want to say even watching in 2x speed, so I think everyone can do. Keep going, nice video :)
I've been watching your videos for awhile now, always top notch! Keep having fun with it and you'll continue to thrive 👍
As others have said the translation was fine, you speak clear and at a good pace, easy to understand you :)
Remember lots of fun with the free-flight version from 1955 called the _Charybdis_ - very hairy LOL 😁😁😁 (think plans are still available on Outerzone!)
Dont apologize for translating. Its amazing that you can speak English and Swedish fluently.
Best LiPo Launcher I ever saw
Also the Swenglish is perfectly charming. You're bringing us little bits of ROSMT years later
Interesting. Suggest leaving the launching rod attached to the wing to stabilize the wing in flight, like a pendulum. Then, with a bearing and a gimbal and two servos controlling the angle of the rod, you can vary the angle of the pendulum to change the angle of flight, like a gyrocopter. The left stick on the transmitter would then control it like an airplane, with elevators and ailerons, to control its attitude. Unlike a helicopter, the angular rotation of the wing currently acts like a gyro to stabilize the wing. You would need a fin on the pendulum, to keep it pointed in a forward direction. If you added weight to the wing tip, that would increase the gyroscopic effect. A wing of that size should be able to lift several pounds, depending on the angle of attack and rotor speed. A thicker airfoil will generate more lift for a given rotational speed. The angle of attack of the wing should be varied, greater near the hub, less at the outboard end, like a propeller blade, with a "twist". Your airfoil may be somewhat thin to generate more lift to accommodate extra weight. A gyrocopter can be thought of as a rotating wing with a pendulum suspended below the wing. In this case, the electric motor rotates the wing, not the forward motion of the blades moving through the air at an angle. Might or might not work - you're the developer, not me.
the swedish subtitles were great! your english is great! do you man, because i love your stuff. i've never seen a mono-wing before, so this was a blast to watch. i also loved how it sounded like the spaceships in Mars Attacks somehow heh. much love from Alaska!
The sound it makes taking off is like a UFO from the old timey black and white movies :) Excellent project!
9:52 THANK YOU!!! 🤣🤣🤣 I laughed and I cried at the screen for the whole time up to this point 👍
Super cool! It sounds crazy and I can't believe it flew that well.
It's also impressive hearing the Swedish language with Subtitles.
Talking about what's happening.
Bro, your English is spot ON. Awesome video!
I like that it sounds like a flying saucer ! Also the ohhh....... 's on impact are all good !
I love watching your videos because you show your failures, I think a lot of people don't realise how much failure goes into success. Failure is what teaches us how to succeed and you always succeed in the end ☺️ Keep up the great work ❤️
So you basically made what looks like a thrown spinning lightsaber for this May the 4th video.
Actually many ships in star wars has same shpe you probably know that right ?
what fun! Very determined and rigidly applied process leading to "maximalt olyckligt" and "bra" crashes. Keep up the work
Great video!!! Your English is perfectly fine. I always enjoy your videos
Great fun! Love to hear the Swedish + Swedelish + English -- All of it!
I like the idea. If I had a 3D Printer, I'd consider only printing the wing's ribs and then assemble with a spar and then cover with shrink-wrap film (as many balsa, RC planes are now covered rather than dopped tissue paper). It would be ultra light and may function even better than what you built.
This thing also has a free flight version. In 1960s, people flew the gas powered free flight helicopter a lot. Also it has a nickname "The Big Knife".
I had a drawing for a design of one of those 50 years ago, for a diesel engine model, though I never tried building it, it was fun watching your attempts though!
your english is perfectly fine and understandable without issue
Outstanding! We can all take a lesson from you on perseverance and a commitment to success.
The translations were good. I know what you mean with it being hard to translate from Swedish to English, as I am swedish myself.
Du gjorde seriöst bra med översättningarna, inte alltid det lättaste att översätta, man vill liksom inte bara direkt översätta utan istället hitta rätt motsvarande ord som matchar. Men du gjorde det bra och jag tror nog alla som inte pratar svenska uppskattar de översättningar du gjorde :)
Btw, fan vad kul att jag hittade en svensk kanal som är så här intressan :D
It was so hard to hold myself back from going to the comments and telling you that the airfoil was rotating the wrong way :D Well you got it in the end :)
Your English is amazing! You always amaze me with your thoughts and ideas! Keep it going, you inspire so many people.
My English is as good as yours my friend and it’s my first language ! 🤣 no worries at all easily one of my favorite channels I always await the newest upload ! Keep them coming !
Imagine sitting on that thing. It would be so much fun!
14:19 Maple seed: "Am I a joke to you?"
you could try modulating either the propeller or add a small control surface on the wing tip to control the orientation.
That would require a whole bunch of extra sensors and computers, though.
You convey very well very articulate well
Nothing wrong with your English. Great entertainment from the "mono wing" - thank you.
I was very happy when you realized that the motor went the wrong way. :D
I would love to see you get this fully under control
As always. Top notch video!!! Thank you!
For the whole first half of the video I was yelling at my screen "you have the motor on backwards!!" lol
This is extremely cool - never thought it would work that well but you sure proved me wrong!
It sounds like a 1960's UFO.
Great video. Keep up the good work.
"Popular opinion wasn't favoring this invention to be a feasible design path for air travel. The surviving test group complained about dizziness, nausea and injuries caused by both hard landings and high g-forces experienced during the flight."
One word. Fascinating ❤❤❤❤. Your right up there with the Wright brothers 😀
Giving you my one handed applause. 😎
It's not a surprise to me that it works as a concept - one-winged gliders have been used as a parachute for drop-delivering goods onto farms etc. Controlling its direction will take some smart electronics, though.
translation is totally fine. Respect that you do it in english. Greetings from Germany
Amazing! It's great that you have the courage to speak English. I haven't get through yet 😅
Super project! 🎉🎉
Protip, those holes actually make the wing heavier. Do the one hole for the dowel and then leave the rest as infill. It'll be way lighter. Add more walls for strength if its too weak.
LMAO.....😂🤣😂 !
I think it's the accent, but when the part flew off the Wing, during testing, it just reminded me of the guy they called the Crazy Russian !
So funny when he would screw up !
Thanks for the humor, intentional or not !
Keep up the great work !
👍😉
As too any translation, please don't change a thing !
It is great !
And I come from a place, where myself and friends were building Flying Wings, and had so many good laughs at our misfortunes !
So I feel your pain !
Lol !
So refreshing to see someone admit to obvious mistakes just like I would do😅
At 824: Your wing is spinning the wrong way relative to its airfoil profile for the majority of it's length. You need to cut the wing in half and face the longer side so the airfoil provides lift.
What a cool weapon!
