chAIR -Manned multirotor Episode 19 Quadcopter style

[@Syalria]

Thanks for new video. It's great that we can follow your progress.

[@amazingdiyprojects]

Stay tuned! :-)

[@birdseyeview1543]

Love what you are doing, ignore the negative, you are a pioneer.

[@amazingdiyprojects]

Thanks, I appreciate it!

[@CamaroRick]

I hope you continue to get funding that is truly amazing.

[@lasersaber]

Wonderful machine and inspiring project. Be careful!

[@tedmarks6836]

Sluggish is good and steady . I think I would beef up the landing gear with a few bowed downward skies.

[@XEvil9]

Amazing how easy it accelerates, even loaded

[@amazingdiyprojects]

Im quite satisfied with the vertical acceleration at 70kg payload. It is impressive standing close to it even when you are just in a hovering state.

[@milamiglia2437]

It's a very cool project but I would encourage you to not be satisfied with the power because so much more is possible. Right now the unloaded vehicle has about 1.3g surplus? if you double or triple the propulsive weight, your mass starts to become negligible. You only have to look at a few FPV drone videos to see what agility is possible when you think beyond bare take off power. I would also encourage you to think well beyond hover. 2g powerful vertical take off, lean into fast horizontal flight. A true revolution in personal mobility. I promise you it would be world headlines. Standing upright hull, two small wings with two powerful motors on each. Wings can tilt slightly with motors on. No other control surfaces needed. Spin down and powercut, ballistic chute for safety.

[@flymeetspaddle]

awesome project man i've had plans of building my own manned quad as well.and i love your approach of using a lot of small motors, but one thing that will help is to take off quickly to get out of your own propwash. especially with a bunch of small motors, im sure you're creating a pretty chaotic air bubble under yourself. Good luck man!

[@IncroyablesExperiences]

Hey, you choose the best price / performance ratio for motors and their controlers ? What are the parts name ? :) For 7$ you can have a reliable set of motor-controller-propeller that provides 0,8 Kg of thrust so around 1000$ for your weight, how much is was for you ? (The more surface of propeller there is, the more efficient is your device because to generate thrust you need velocity time surface wheraes the power consumed is a velocity square fonction)

[@Migueldeservantes]

I would say that a few inner tubes for basket balls as a landing gear will be a good idea.. not all landing conditions are equal.. and I would like to see your spine in the same place permanently!! great work wish you the best...

[@TomGoethals]

amazing, I'm wondering how much of a difference it would make to test with a 70kg. test dummy. These jerrycans are rock steady and their weight is pretty low centered. Before getting in I would do a test flight with a dummy first. Wishing you the best and be careful!

[@allenlong1445]

Tom Goethals so true.. how dose it handle being top heavy ?

[@oliveranthony-sparholt5113]

always better - like balancing a pencil on a finger

[@CrispyVideos]

Glad I saw this. Amazing work!

[@TheMoonDr]

I suggest having a ridged frame, have the rotors mounted that way is going to make for very sluggish flying, and create alot of slop in the sticks. Plus the safety factor, you could use that type of mount as a back up if the ridged frame broke, but not as a main part of the frame. If you want to rotors to move up and down, which I dont see why, consider using hydraulics, but that just going to add more weight. Also consider using a 3 blade prop instead of the 2 you currently have, to improve throttle response.

[@-Sunny--]

And when you are in the air, you just tilt the whole thing 45 degrees and fly superfast! Promise to catch that on film too! Keep up!

[@johankarlsson9720]

Fantastic!! So much fun to follow your progress. And as someone said, would love to see it "live". Maybe ask the local news to come have a look? (C: Anyway, all the best and keep up the fantastic work!!

[@GiesbertNijhuis]

Excellent! There is the risk of collapsing "wings", when upside down or such. I like the wires though: low weight. Looking forward to the next video!

[@amazingdiyprojects]

Thanks, I must admit that I am counting on gravity to never fail, call me wreckless if you like.....LOL...true, this is a pure positive G:s aircraft. Yes kevlar wires rather than stiff struts save allot of weight.

[@ahaveland]

Coming along nicely! I hope you'll soon be able to do a video of it doing a course around a field before actually daring to climb aboard! I guess you'll add GPS and waypoints later. Regardless of manned flight, being able to transport 100kg payload around could be really useful!

[@MegaFPVFlyer]

GPS is just another potential point of failure IMO.

[@notanotherrcchannel]

Have you considered a saddle-style seat? In the event of a mishap it may be helpful to be able to extend your legs downward, or perhaps to jump off/push it away entirely. Thanks for continuing to post updates! This is great :)

[@AV1stra]

Wow, you really do live up to your channel name. I wish I had the space, time and funds to build such an awesome project, maybe some day. Keep the dream alive!

[@freddoc4771]

Can't wait for your next video, take care !!

[@modfabcom-au9909]

Excellent progress!

[@manuelpellizzari8540]

Hi, it's good that you seem to know what you are doing, please keep on not being overconfident and be vigilant at all times. I know you are limited by the inertia of this thing, but have you tried cranking up the P-gain up to observing oscillations due to overcorrection ? You probably know that right before this point you will have the tightest control. About the Hiller flying platform, I remembered the self stabilization preventing fast forward flight was not so much caused by the air pressure on the pilot but instead by the effect of the duct around the props.

[@amazingdiyprojects]

True, thanks for the input.

[@onjofilms]

It blows my mind how far batteries have come. To move that much air from such a small space is amazing. You can power a house with that. And not have to pay Tesla.

[@captn_hanky]

when can we oder it at amazon?

[@MegaDragge]

Häftigt duktig du är. Tittat på i verkligheten hade varit en kick kan jag lova :)

[@moomoomoomuu]

+

[@nicolaeivanescu2253]

this is straight gold

[@johnnyj540]

Didn't know it was that big until he walked out.

[@tdavidgraham8675]

It would be interesting to know how you zoned the flight controllers, and why. I think I understand that using five controllers and radio systems adds safety. Whew! What a project. I thought I saw in one of your on-board camera shots - the way the motors started in groups - that you have zoned the controllers in an interesting arrangement. Is that something you are willing to share? Thanks. I am really enjoying this project and your generous presentation.

[@michaelallensteele]

Probably needs more I gain to counter act the wobble. Looks like it's working when you turn off one of the FC's. What do you intend for failsafe event?

[@locouk]

I'm still trying to get my head around the complexity of it, having a fault and locating it must be a nightmare.

[@gadgetmerc]

I would agree. One of the flight controllers was turned off but all of the props spun due to all of the air moving over the unpowered props. You would almost need a test mode where each FC would give each motor 'min command' in order so you could easily see if a motor was having a problem.

[@inlinefilms2152]

Awesome job! hope to see you fly on the next video.

[@amazingdiyprojects]

That is the plan :-D !

[@realtvnow]

Silky smooth 👌☺️

[@danheeks]

Excellent work! Thanks for showing your working; your failures aswell as your successes. For the yaw problem, having same direction propellers is cancelling out the torque effect. I hadn't thought about this until you started describing the problem. Thank you. Is it worth having a mixture of propeller directions on each disc, instead of angle change? ( I guess the control software would be really complicated, but possible ).

[@JackSpiggle]

I chuckled at this comment when I saw it but now thinking about it thats actually a really smart idea. Probably best left to someone designing a new system from scratch as adapting it here would be difficult and introduce so many more potential points of failure (from the software side that is)

[@darkangelmusic8316]

Can you kindly share calculations that you made while selecting blades and motor for respective payload

[@Dimka33100]

Very,very nice Job !

[@fraserashworth6575]

Very Impressive, one FC down, -16 motors, more than stable enough to get it down and fix that FC.

[@amazingdiyprojects]

That is my assessment as well. Im thinking; don't try to fly "home" unless you are over water, just land safe and fix the problem or disassemble and carry it back.

[@bogenriederlukas]

Flies wonderful!I think you should add a little bit to your frame maybe. If weight allowed that.

[@nullerdk1]

this one is giant, what is plans with it ? and when do you take on the helmet and try ? thanks for vid cool job

[@oliveranthony-sparholt5113]

Great again - Tak

[@iw28mo]

Just amazing ! how much was the total cost i may ask? as the lipos and motors must be expensive?

[@airgunningyup]

I hate to tell you this, but I think the neighbors daughter will notice you hovering over the swimming pool with this (-'

[@m1ddleagemadness]

what about a bird strike, how many motors/propellers can you loose before you crash?

[@MrDjax]

he did switch off 16 motors at a time in the test dude

[@m1ddleagemadness]

oh cool

[@davidcerva9864]

Can you put camera on pilot position? :)

[@amazingdiyprojects]

I will!

[@davidcerva9864]

Awesome!! :D

[@RenzVC]

why are you not fixing the circles in their up position?

[@PFANDFRAI]

great progress again! congratulations! whats next on the list for the coming part?

[@amazingdiyprojects]

If everything looks good (I have not had the chance to check out the craft in daylight after previous tests) I will try hovering the multirotor tomorrow, sitting in the (ch-)air. Weather condition seems to perfect anyway according to the forecast.

[@PFANDFRAI]

YES man! wish you all the best for another glory step forward, keep us updated!

[@prav077]

3d printed jet engine u made can it run an aircraft???

[@jimbopaw]

Are you happy with the stability?

[@amazingdiyprojects]

Yes, I am. It is almost as easy to fly as any model quad copter. The only ting that differs is that the joy stick is not self centering so you can not let go of the sticks and let the craft self level, which could be a problem if you for some reason suddenly would loose all visual reference points.

[@forfengeligfaen]

Is there any disadvantage to having multiple flight controllers? I assume that effect any one flight controller can have on the craft is only a 1 / n of the possible effect (where n is the number of flight controllers) If this is true, does it matter?

[@kdevrees]

How long will the batteries last?

[@amazingdiyprojects]

After 14min you are as dead as your very expensive LiPo:s, after 12min you are stupid not to land and after 10min you should aim to land.

[@stackoverflow128]

Very nice. Do you intend to flight it with wireless tx in your hands?

[@amazingdiyprojects]

Yes, but the Tx is mounted on the airframe (don't want to drop it in a freak accident) and it is actually not one Tx but rather Five independent which work in parallel.

[@stackoverflow128]

amazingdiyprojects it must be tempting to remove the radio element completely when you intend to fly it being onboard. good luck with your test flights.

[@rtesimpson]

I don't understand why the four banks of Motors don't all rise together at the same time... you always get one or two coming up before the others when you initially apply power...

[@elfkind5590]

As a victim of my own ignorance, I have had 2 different prop strikes to my fingers this week with 2400kv motors resulting in LOTS of blood, pain and nerve damage. This leads me to ask one simple question here..... WILL IT BLEND?

[@costasvrettakos]

how you gonna sit in there?

[@dahlmas]

Costas Vrettakos hi will remove the jerrycans lol 😜

[@costasvrettakos]

chum drum yeah the problem is that humans have legs also that you need to get in and out from somewhere. he is not the can for someone to cary him in the seat.

[@gadgetmerc]

His legs fit in the space between the hoops. He can lift a hoop and get into the seat and then power it up. Have you seen his previous craft? Clearly its designed for him to fly in it.

[@costasvrettakos]

gadgetmerc yeah i follow this guy for a long time. his previous craft had motors only left and right so he could walk in easily. this one he is surrounded from blades which spin exactly at his neck height. i wouldn't sugest flying this thing. if something happens he cant get out from there.

[@dpqbpqbdpqbpqb4754]

"Why...ever put the cockpit/weight BELOW the props" If the tethers that hold each of your quad lobes ever break, you will find out why. :D :O :< You need a roll cage, and a fat suit.

[@gadgetmerc]

He should write up a will that states that the final video must be uploaded to his youtube channel. I hope they blur out parts if they must but come on... for SCIENCE!!!

[@amazingdiyprojects]

But of course, -FOR SCIENCE!!!

[@thakurkamalsingankit2011]

What I control 4 motors in one transmitters

[@christopherevans5197]

Congratulations on your success, but How do you control 5 parallel flight controllers at the same time electronically and does each flight controller control all the motors or only some?

[@amazingdiyprojects]

With 5 receivers controlled by 5 transmitters....Check out previous episode, (Part 18) They only control 1/5 each.

[@christopherevans5197]

So each flight controller controls 15 motors? Individually or in Parallel? Are you using all the available ESC outputs on each NAZA?

[@mikeyfreeman5776]

wow already a new video!

[@timwilson3435]

How do you transport this thing? Do you disassemble it?

[@ufoengines]

SO COOL!

[@ahmetaksit7481]

hello. this project what happened now. ı dont see new video.how do final versiyon. we are waiting

[@geniuscrash66]

Have you a manned flight planned?

[@amazingdiyprojects]

Tomorrow!

[@Cloudbumps]

wow, amazing!

[@vjay8196]

Sir trance meter and receiver how to connect

[@ivanivanov9070]

Good luck!

[@johnnyj540]

How do you control yaw?

[@amazingdiyprojects]

6 degree tilt on all motors in opposite directions.

[@Berserker71r]

What's the total mah of that lipo setup?

[@amazingdiyprojects]

416000mAh....LOL...= 80x14.8V, 5.2Ah LiPo batteries

[@Berserker71r]

That thing must be pulling close to half a million watts at full throttle!

[@amazingdiyprojects]

Yeah, that sound just about right, it hovers at a quarter million anyway....LOL

[@izzyplusplusplus1004]

So much better!

[@deantubeful]

Awesome

[@drhirsch7979]

Very good work, but to much engines and super dangerous with those props!

[@JHF80]

Kommer du til å styre med radiokontrolleren når du skal sitter i pilot-stolen? - Are you going to fly it using the remote controll when you are sitting in the pilot chair? -

[@brandonb417]

Having the CG above the rotor blades is a perfect example of computers being able to compensate for people's stupidity. Why finesse it when you can brute force it. I suppose they don't realize it takes more power to keep it upright since a lot of the motors will have to rev up to keep it upright. Oh well, when you ignore physics, it reaches up and slaps you in the face.

[@alytechnology]

im waiting you to sit there and fly but be carefull and make sure that you wont be injured

[@Thailand-Servant-111]

I Cheer you

[@kognitionwings4597]

Bravo!!!!!

[@Jeppelelle]

Hur är redundansen per "ring"? Finns det någon SPOF som skulle få samtliga motorer i en ring att stanna?

[@BoHolbo]

Jesper Andersson What do you mean by SPOF?

[@Jeppelelle]

Well, (single point of failure), electrical stuff that is connected in series instead of parallel without supporting dual failure modes, everything should be dual, dual connections (100% separated) between FC and batteries, dual connections between FC and ESC (100% separated), dual distribution boards (if used) etc etc etc. Almost no quad have dual failure capacity but in this case it would be fairly bad if a complete ring failed when flying with a human onboard, fault tolerance is key and ideally any manned multicopter should also be designed to support graceful degradations. I don't want more regulations in this hobby or even business because someone built an unregistrated multicopter and crashed it

[@BoHolbo]

Thanks for the well formed explanation:)

[@yoanaerodrone3043]

nice

[@jeffvenable3845]

just wow

[@g-mech1244]

Just hop on it already!

[@RETROGAME-FIX]

Amazing! imagine if u cud do a barrel roll with this!!!

[@amazingdiyprojects]

You can do that! ONCE....LOL

[@danp762]

very cool very expensive hobby. :)

[@amazingdiyprojects]

Yes it is, I have hole in my shoes, you sure got to get your priorities right, to afford this hobby....:-D....no joke.....

[@prav077]

pls reply

[@gun_nerds]

93kg?! What are you looking to transport, my hamster? Make it 193!

[@amazingdiyprojects]

Cost is proportional to payload....I am not rich and weigh under 70kg so.......

[@pumpuppthevolume]

multirotor.......u ain't kidding

[@camaro92026]

ok now get in it and fly to grand ma's 🏠

[@8vinc8]

Wow wow wow

[@mrfourtysevenman]

cool let me fly it now my turn

[@AdversityZone]

no need for 40 motors mate kzbin.info/www/bejne/eWjcc4qcpq2derM#t=0.996958

[@amazingdiyprojects]

Great video thanks! Well, just as many other amazing flying contraptions on youtube it is flown over water. This is directly coupled to that fact that those machines does not have lets say....76 motors ;-)....mening that they do not have enough redundancy to fly over hard terrain. I think the craft in the video clip would have a very hard time coping even with the loss of one singe motor or ESC. And that really could happen you know.... Also the relative small swept area results in low efficiency which in turn gives the craft short flying times, 4-5 minutes seems to be their safe flight-time limit. But Awesome and cool never the less!

[@ryccoh]

I think kitty hawk is one of the two flight companies funded by google. I bet you could totally land a job with them and show them how its done.
