- Laxå flygplats 2019-04-17. A speed test has been on my list for a long time, and now is finally the time. The structure is optimized for light weight and hovering flight, which becomes apparent in this speed test where the back side of this design surface, namely high drag. Sitting in the chAIR it fees pretty speedy but the actual ground speed of around 50km/h is not very impressive. There is still headroom on the throttle but when flying the vehicle it is apparent that air resistant becomes a significant counterpart around 50km/hand the overall flight efficiency drops. A maximum practical take off weight test will be carried out later on this spring.
163kg TOW, 35kg LiPo currently mounted on the craft.
Typical hover efficiency 7.5-7.7g/W
Setup:
FC 5x KK 2.1 running stock 1.6 firmware
Motors 76x Multistar Elite 5010 274Kv
ESC 76x afro 20A HV, with one extra 63V 330uF low ESR capacitor fitted to each ESC to handle the long current path from battery to ESC.
Batteries 80x Multistar 4S 5.2Ah
RC 5x Turnigy TGY-i6S Digital Proportional Radio Control System
All of the above purchased from Hobby King.
Total cost approximately 10.000USD - Наука та технологія
Is there a reason why you are still using a timer on a manned drone? To me it would make more sense to have a voltage display or a "Fuel Gauge" seeing as how you are physically on the aircraft. Very cool project and i'm looking forward to watching more of it.
Well, I want to answer simplicity, but when doing multiple start and stops, using a timer is not a very simple or accurate method of keeping track of how much flight time you have left. The thing is, that I started out having the battery bank fractionated for redundancy so that to get an accurate picture of discharge state I would really need 20 voltage meters, but now two flight seasons later, seeing how evenly the batteries discharge there really is nothing wrong with just sampling one or two battery packs for a good enough indication of overall battery status.
Maybe you could automate the timer to start and stop according to a minimum throttle speed of a few of the controllers? Or a few ground switches on the bottom of the chair? Just curious, wonderful build!
@@amazingdiyprojects Wouldn't you simply need the minimum voltage displayed? After all, if one of your packs is nearing critical low, you'll want to set it down anyway, right?
Fuel gauges are not practical in this type of prototype.
A timer is going to give you a end time within a known safe period. Ignore the timer at your peril.
I would suggest tripping the timer on arming like you can do with most RC models though. Having to split your attention and remember to arm the timer each time is a problem waiting to happen.
@@amazingdiyprojects you do realise that if the batteries are in parallel, they will equalise, yeah?
Who care how fast it goes? You’re FLYING!!
yeah, it's awesome!
Facts he made it happen
Hovering is enough for success for me. Doesn't have to move an inch.
It’s very exciting. Feels like technology is finally catching up to our imagination.
People like this guy push the industry by making their imagination real.
3D printer were talked about for decades but only became a practical and affordable reality because ambitious people made it happen.
I think personal, affordable, safe and easy flight will finally happen for the same reason. Pessimism is cowardice. Our dreams are coming true.
You must not be american
50km/h is more than enough for the occasional night time beer run !
Pull a Tucker Gott and do "Flying my personal multicopter to McDonalds"

I have been watching your activities for quite some time now, and find them fascinating. I fly multirotor machines, not manned, and get a great deal of enjoyment from them. I will soon be 85 years of age, and only wish I was younger, as I feel I was born too early. Keep up the great work you are doing.
Go to panama and do stem-cell injections, in combination with keto diet that will keep you alive for another 20 years which will be enough for this guy ( david sinclair)to prolong your life with his research.
Just google joe rogan and stem-cells panama and then also proffesor David sinclair.
There is still time for you old man, to become a young man :)
You're an inspiration buddy. It's great to see someone engaged in a project that lights them up.
The amount of time, money, patience, knowledge, etc... that this project must have required is astounding. Hats off and two thumbs up for your achievements !
Keep doing what you do and the future is sure to bring you great opportunities.
Wishing you the best...
Miss your great videos! Hope you are well and still doing that great stuff.
WOW well done. I have pretty much followed you from the start of your project, and to watch you fly around like this gives me goose bumps.
Great job on this, stay safe, well safe as you can. You and the other guys doing this are definitely pioneers in this form of flying. Years ago, the first time I flew an RC quadcopter this is the first thing that came to mind, a manned multi rotor. I congratulate you on taking it to this level. I'll be watching and dreaming. Good luck and thanks!
A very well done! Your projects are always amazing! I must say you've chosen the most appropriate name for your UA-cam channel.
Very impressive bro been watching you for years...

No need for that..
This is Sweden (say it with the voice of Gerard butler in movie The 300.. this is Sparta)
'It's a huge privilege to sit in the chair and fly.' You are too modest, Sir. It's your chair, your flying machine, and it wouldn't exist without you. You deserve every bit of that privilege!
Amazing progress man. It’s must be an absolute joy to fly in something you unique in this world that you painstakingly built.
very refreshing to see someone actually applying dymaxion principles
Amazing, as always, of course! Frohe Ostern! Happy Easter! Glad Påsk!
Your incredible character shines in this project. May you be blessed with health and further progress.
This is just such a remarkable achievement, congratulations again! The control you demonstrate makes this project look so refined, it is easy to imagine practical applications. It looks so fun though! Thanks for sharing.
The project in itself is, as usual, totally amazing and hopefully a lot of people will get to appreciate your ingenuity and fabrication skill through your videos. Furthermore, I think your video editing in this is spot on, which is a talent in itself. Great cuts between action and exposition, it never gets dull. Since I was there, I can say this video is in some ways even better than seeing it live.
Thank you for those kind words!
You, sir, are my hero. Amazing DIY project, indeed.
Dude, I cannot convey how cool this is, it has to be the coolest things I have seen on youtube, scratch that on anything!
Beautiful execution of a complex system. The result seems somehow organic. Very graceful and and powerful for such a light creation.
My dream has always been to build something like this and while I haven't had the money to do it yet I just want to thank you for actually following through and inspiring me.
Leaf Blower: "Well, I'm out of a job!"
Lawn Mower: "If he gets any lower, I'll be out of a job!"
So lovely to see you enjoying the fruits of your labour. You are inspiring!
Very impressive!
I love how your always so in tune with what you enjoy and the things that give you pleasure. Your passion truly does shine in everything you do and say.. Thanks for sharing!
So graceful! Looking forward to placing my pre-order!
i wonder what the cost would be for a pre-assembled model.3rd of a mill? about?
@@leemaples1806 I think it was closer to $5-10k. Prob cheaper as he previously tried various methods and spent more money developing it. It's simply quad copter parts mainly.
wow. if i could get all the parts in a kit for under 10k i would sign up for one.
Everybody will be flying a helicopter/multirotor someday, at the rate this is going.
+1 on the pre-order.
That thing is amazing!
Glad to see it out of ground-effect finally... time for altitude trials!
Big Time!
Bring a parachute.
i think we all want to see a manned altitude test. i would thinkthe best place for that would be over water? but, what about water-proofing.thats a whole other issue i suppose.
@@leemaples1806 Lol, water don't get him past that slice-o-matic, He'll have to do it in increments. The Flybye was at least 30', next 50', 75', then a 100'. I think the best thing is to stick a 170lbs of sand bags in it, and see how long it'l fly remotely.
This is the problem with this type of aircraft, you have a failure, you are toast. And unlike a helicopter, you cannot autorotate. The typical cruise heights make parachutes impractical. Failure is not an option.
So great to see the progress you've made since I last saw. Pioneer and all around good man.
AMAZING! What a crazy project, cannot believe you pulled it off!
Superb. Genius!! Love the redundancy.
Hey man! Hope everything is ok! Haven't heard from you in a while! If you're taking a break, then enjoy it! It's well deserved!
I think something happened 9 month without any info. I think he let us know if he wanted to take a break :(
I must say this is the most impressive attempt at this I have seen to date and I follow a lot of projects.
Good to see you are taking your safety more seriously. Part of being a pioneer is living to talk about it!
Hi, With the 17x5 props, you are currently displacing 1135ci volume of air per a single rotation. With the maximum amount of static thrust being at a ratio of 6 in forward propulsion to every 10 in diameter, a 14x8 prop would give you slightly ( just less than 10% ) more static thrust (for lift), but would increase your speed in forward propulsion by 60%. If it creates too much load on your motors or ESCs, you could go with a 15x7 which would give you about 6% less static thrust but still gain 40% more in speed. Hope this helps and Happy flying!
The pitch is way to high the efficiency would go down like hell
@@peterzingler6221 Actually, it's the a ratio of 10 diameter to 6 forward is the perfect pitch for lift to get the smallest diameter prop without loosing lift. Unfortunately, most props are made at a ratio of 2 Diameter to 1 forward at the most but that is an easy one to find props for such as my hex with 15x7.5 props.
Over the 10x6 ratio and you start loosing lift efficiency, draw more amps, but gain speed. Under that ratio and you've lost both lift efficiency and speed.

Very cool! For now I've given up on my project to build a internal combustion quad rotor due to time and money, but it's so great to see this craft in the air again. It's simply brilliant in so many ways. Well done!
the string tethering is absolutely INGENIOUS
how long does it take to charge all this
Hope you're doing ok. No posts for a while? Looking forward to seeing a new video from you soon!
Wow!
A manned drone-competition would be awesome! I'd absolutely LOVE to see the different designs up against each other!
Unglaublich, bin Mega begeistert von deinem Projekt. Für mich die BESTE selbstgebaute Flugmaschine die ich hier je gesehen habe. Sieht so aus, als würde es richtig viel Spaß machen damit zu fliegen.
P.S bin froh, dass du jetzt immer einen Helm trägst 👍
Damn, 8 months without any activity on youtube, I hope you're okay.
No idea what happened :(
@@GoncaloRijo Maybe he crashed and hurt himself bad ? He did crash the petrol powered one he made but luckily didn't hurt himself
@@diyguy928 I hope he is OK... But I'm starting to be afraid of something bad happened...

I remember when you were building the first chair! You are a pioneer and have come a long way, congratulations!!!
Great project. I was smiling through the whole vid. Looks like great fun!
nice Venus fly trap ya got there if those strings snap buddy.
6:28 You compared the drag coefficient of a sphere (0.47) to a streamlined body (0.04). In fact the value for a cylinder perpendicular to flow ranges from 0.7 to 1.2 depending on things like surface roughness & Reynolds Number. However since the craft pitches relative to the direction of travel, there is no way to properly implement a streamlined cross section, so what you have is as good as it gets.
Sir, I am guilty of laughing at this when I watched your earliest video. Now today! Bravo Maestro.
The best compound-copter yet. Keep it up!
Who designed this? They're a genius. Also, makes a change to see one of these fly at speed, rather than just endlessly hovering.
dude he designed it he's the genius
No problem bro, I'll fly it for you so you can watch and feel the airflow from underneath 😂
That is just above and beyond bad ass engineering and brave piloting skills. You Rock brother! Awesome work.
Dude that’s so incredible!! I’d love to sit in something like that. Way to go buddy
Hey, noticed you haven't posted a video for a while. Hope everything's ok?
He's now flying upside down

Looks like fun ...must be very rewarding to have designed something so different and have it work so well. Blessings to you and yours in Jesus' name!!!
Oh for fuck's sake, get your god mongering out of here. You're in the wrong crowd buddy. Keep that bullshit in America.
Thank you for not being afraid to acknowledge our Creator sir. Respect
@@flybeep1661 U should know that Jesus Christ is Lord of the whole earth not just America :)
This is so exciting to watch. I can only imagine what flying over the trees must feel like
Congrats on the great results!
And thank you for sharing this with us. =)
Have a nice summer. Fly safe.
Hasn't posted in awhile, hope he didn't get hurt in a crash or something
Yes, exactly what I was thinking.
Great project. Glad to see that you have "proper" protection equipment. Cheers from Toulouse, France.
Congratsss man!!! keep us posted on your progress. I'ts a preassure to see that things! Hugs from Barcelona!
No update yet ? Please, tell us that you are ok !!!
Wow, didn't know this would come back! Maybe you should stop before you get yourself hurt, but it's very very interesting to watch
I am so happy I found this channel! All those projects are very amazing. Its weird that you have only 60k subs with such great projects.
PS. Got and idea:
To build some kind of vehicle (like 3wheel bicycle) that will run purely on solar panels mounted on top. And maybe some supercapasitors as buffer for passing areas cowered with shadows.
That's so graceful. Nice job done there.
This shit reminds me of Hey Arnold episode where the man has all the pigeons who fly him away.
More than 5 months without a post :/ Are you OK?
Fantastic build. The control is so precise and smooth
Vous êtes un pionnier de l'aviation en drone! J'espère que l'histoire retiendra votre nom, comme Blériot, White, St Exupéry! Vous êtes un héro génial! Bravo, Monsieur🙌
Put it in Acro mode Buddy and you can do 100km :) Joke apart, you have done a great work buddy. stay safe
Imagine driving down the highway and you see that one guy on his regular morning commute
I would convince my employer to let me build an ultralight landing pad on the roof.
How coool is this, i nearly cried. Out of words. Stay safe.
This is simple AMAZING. Here we have the future of the trafic. Excelente y maravilloso¡¡¡¡¡¡
The next question is how far can you go? Looks realy good and realy stable in the air!
you can actually go so far with it there's no coming back from it ha ha
*really
We all know Natalie had emergency services on speed dial...
"You dial 91, and then when I say, dial 1 again".
Wow this flying chair looks pretty cool. Really enjoyed to watch it flying in the air. 👍👍
Been following this for ages,I absolutely love it,and want one.
What if there is a power outage problem, what safety measures are in place ? Just curious, not criticizing.
it would just drop like a brick. its a simple quadrocopter. verry dangerous indeed
I am not sure if he has any redundancy in place. Ideally there would be two independent power sources making it exceedingly unlikely that both would fail simulateneously
But how high can it go?
Very well done sir. I recognise and salute the determination and discipline you have applied to achieve your requirement. I once designed, built, and flew an RPV autopilot back in the 1980s but senior management at the company reckoned that RPVs would never catch on. How short sighted and stupid was that! Keep living your dream and I hope you get industrial support in moving forward. Fantastic.
“Walking through the air@.
Such guys as you give us the future
You definitely need a field charger. Or spare batteries :)
May be they have a Tesla Supercharger at that airodrome :-)
Or replace the batteries with super capacitors
Daniel Hughes
That would make battery life even worse. Supercapacitors just exert energy faster, meaning they would have much worse battery life than batteries.
@@-Burb One of major advantages of supercapacitors - virtually unlimited charge-discharge cycles. The catch - energy density is too low to replace regular rechargeable batteries. On a bank of supercapatitors of the same weight as li-pos - expected flight time will be something like 30 seconds instead of 10 minutes...
PS: it needs an arc reactor :)
Put carbon roll bar on.
Useless and more weight.
It's simply fantastic! I can't believe this happens in reality! This is our future!
Flying that looks immensely fun!
Really cool. Anyone know his name so we can look up to see if he has had an accident or is still alive?
Axel Borg. I could not find anything though.
Why don't u post anymore
I can watch this for hours.... AWESOME !
there is several apps that tell you your speed (on your phone)...wouldnt that have been easier?
K.I.S.S.
Why risk fucking up a flight on an experimental craft by adding complexity, and taking brain power away from the controls, when you can simply match speed with another big ass vehicle?
No accurate GPS-speed?
Beautiful work. Congratulations and thumbs up!
Oh my gosh, this is amazing! Videos like these should get more views.
I HAVE TO KNOW 2 THINGS!!!
1. What is the flight time your getting?
2. How high does she go?
Being that it lifted him quite easily off the ground, probably a few hundred feet. The wind up there would be a problem though haha
5 months no updates... did he had a drone accident?... I hope hes ok
Maybe he crashed and hurt himself bad ? He did crash the petrol one he made but luckily didn't hurt himself
I love as you care, maby he is building more drones in China to sell
Great video can't wait for it to come out on the market , can't wait to fly it .
It looks so easy to control I’m so happy to see this in market soon
Is anybody here from Sweden? Lets try find this man?
This video is shown airporn neer Laxa city in Sweden. I found it on google map. This man Axel Borg. He is living Orebro, Sweden. Lets try find this man, and know what happend. You looked his materials and now forget about him!! Why?? Have you got any heard??? People, answer me
nobody cares about him? Hello!
It's been 5 months since your last video. You posted at least every 2-3 weeks before that. Is everything OK? Can someone who reads this give us all any news? Thanks.
Now 8mth, not looking good he could be dead with all these high risk activities, hopefully just taking a break and spending more time with his young family...
@@noproblem2big337 or maybe he is preparing something really big
very underrated channel. keep up the excellent work 👍
Still wondering why you don't have way way more subs and views, I have been folowing your channel for a a while and the things you are making are wonderful and amazing to see!
Please keep up the awesome work, thank you for sharing and as always keep building👍
This is the last video, it is 8 mounhts ago. Are you alive?
