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
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

    Your project is wonderful and should be known all over the world
    As I told you in another video
    Do you want us to do the voice dubbing of your videos in Spanish and Portuguese? I do dubbing. Your projects are wonderful and would arrive very well in other languages

    You would be very wise to ensure that the pilot and anyone near that vehicle has industrial grade eye protection. There is no telling if/when a propeller might break or what debris will be blown out by the down force.

    Sir how much it price. I want to purchase it

  4. Dither Jannev on April 14, 2022 at 5:56 pm

    A balloon shock absorber under the body would not be too much for an emergency landing.
    Greeting from France !

  5. gnappibr on April 14, 2022 at 5:56 pm

    This is an excellent project to be sold as a kit for the person to assemble at home !!!

    How do you charge 80 lipos omg

  7. The Slick on April 14, 2022 at 5:59 pm

    the string tethering is absolutely INGENIOUS

  8. lonnie776 on April 14, 2022 at 6:00 pm

    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.

    it sounds like a load of bees wen your flying it

  10. joshua kotei on April 14, 2022 at 6:00 pm

    Wie kann das Sein das sowas erlaubt ist ml

  11. Do you belive on April 14, 2022 at 6:01 pm

    Fans small over and not have carbon fibre glass cover on at all for control wings and wins. For save power

  12. Rgb Rides on April 14, 2022 at 6:01 pm

    hand me that chopper! nice

  13. Victor jeanfranco Herrera tavara on April 14, 2022 at 6:02 pm

    What happen with the chair men? you’re amazing and the chair its increíble!

  14. Энерго Альянс on April 14, 2022 at 6:04 pm

    Hello! Can I ask you what components I need to buy to create such a device on my own? And a guide for creating it. I need it to fly over fields of corn and sunflower. Of course, gratitude on my part will be mandatory!

  15. Dan Ko on April 14, 2022 at 6:05 pm

    I have a solution to the shaped tubes that doesn’t require a rebuild. Attach lightweight, non structural, swivelling clip on aerodynamic vanes to the existing round tubes. It’ll rattle and increase mass by 10kg, but it’ll reduce your drag.

  16. Droning On on April 14, 2022 at 6:05 pm

    How much? So would love to fly this. Brilliant job

  17. Love G on April 14, 2022 at 6:09 pm

    11:49 what planet is that?

  18. Abung Inside Musik on April 14, 2022 at 6:09 pm

    If indonesian people see this,, you will get view more than 3 million view because it’s so cool

    Not a "drone", it has a pilot onboard.

  21. Z и V on April 14, 2022 at 6:11 pm

    Das ist fantastisch!!!

    Hello again. I’ve been following you for quite a while, and you are my "hero", at least from an inventive perspective.
    I was originally thinking I would build a gas engine powered quad copter with variable pitch rotors, but have since switched focus (sounds so pathetic to say I "gave up" – but I could see the obstacles were large) to an electric vehicle. My current project is to build a model of the BlackFly manned UltraLite VTOL (google it if you’re not familliar). The moment I saw it, I knew it was ingenious with a design that has fewest moving parts (to fail). I’m wondering if you have any insight into how to select high power motor/prop/ESC combo’s given the incredible work you did with your manned "quad" (76 motors??) copter. Apparently, the founder of "Opener" the company developing the BlackFly has patents on motor design which focus on reducing eddys in the rotor shell by building it with thin laminations of silicone steel separated by thin layers of epoxy. I’m just wondering if you’ve had any experience with this type of high power motor. The BlackFly design is VTOL capable, but travels in cruise like an airplane, so the high power requirements of the motor are for limited time periods during take-off and landing. I hope to someday build a full scale model similar to the BlackFly. Right now, I’;m working on a model to work out the flight controller software which I’ve written myself with the starting aid of Joop Brooking of Netherlands. I’m doing the orientation calculation using Quaternions so its quite a departure from Joops original code.
    Cheers, and keep on inventing. You’re an inspiration to us all. Many thanks for the thrills and the knowledge you’ve shared.

    "Hey fam how many rotors you want?"


  24. West Nile on April 14, 2022 at 6:14 pm

    anyone see the curious glare on 12m12s

  25. Miguel Boisvert on April 14, 2022 at 6:15 pm

    How did you connect the transmitters together?

  26. TJ Boogie on April 14, 2022 at 6:17 pm

    Oh dear…

  27. Diving Falcon FPV on April 14, 2022 at 6:19 pm

    As many times as I crash my drone this would be scarey.. id prob fly safer for first few thousands flights lmao

  28. Johannes Sjolte on April 14, 2022 at 6:19 pm

    I’m happy that you wear a helmet now!

  29. Abdullah Bal on April 14, 2022 at 6:22 pm

    Can you tell me the brand and model of rope you use? Also, can you send a detailed photo of the motor mount?

  30. ChipHazard on April 14, 2022 at 6:23 pm

    what would scare me the most is not the falling down failure mode (you are close to the ground), but falling up failure mode. What if the thrust potentiometer fails, or the flight controller fails, and you go into an uncontrolled climb? To think my life rides on one cheap potentiometer…

  31. Victor Tsykunov on April 14, 2022 at 6:23 pm

    We’re is this dude now?

  32. edward kearle on April 14, 2022 at 6:24 pm

    I’d like to see rows of propellers that were able to be tilted giving u directional thrust without having to tilt the whole craft, that would also enable a more aerodynamic build.

  33. caro baez on April 14, 2022 at 6:26 pm

    holaaa excelente video me gustaria que permanezcan haciendo contenido similar!!! Voy a seguir mirando sus creaciones. Les envio un saludo chau 👍🏽👍🏽👍🏽

  34. AKASH 46 GAMER on April 14, 2022 at 6:27 pm

    The products which u given was not found in web. After I searched in the hobby king web . But these products are Undevevered ok. Don’t cheat

  35. free juice on April 14, 2022 at 6:30 pm

    keep up the good work

  36. Eddy Santa on April 14, 2022 at 6:30 pm


  37. angargoy on April 14, 2022 at 6:33 pm

    The design is very interesting many engines is a safety symptom in this design if an engine breaks it is possible that the prototype continues to fly. My congratulations

  38. Алекс Эколог on April 14, 2022 at 6:33 pm

    Игрушки многие любят, может пора выпускать хорошие микровертолеты- безопасные, дешевые, надежные, удобные.

  39. Alex626 on April 14, 2022 at 6:34 pm

    You should advance this project further. I can’t watch videos like this without remembering about your awesome project:

  40. drones r us on April 14, 2022 at 6:34 pm

    Smmems like if them strings snapped you get motors to the face

  41. SOSAR on April 14, 2022 at 6:35 pm

    Bad commentary

  42. Ritesh Salwadiya on April 14, 2022 at 6:36 pm

    Very nice job! Very Creative!

  44. Andre Souza on April 14, 2022 at 6:38 pm

    Hi how do you connect so many motors to esc and flight controller? Do you have a main flight controller that it manage other’s? Thanks you

  45. DIY-Dude on April 14, 2022 at 6:40 pm

    How much Wattage do you pull to Hover?

  46. Miguel Boisvert on April 14, 2022 at 6:48 pm

    Just one question, how did you get all the motors to work? Like Betaflight or Naza only supports 8 motors top. Do you mind if I email you?

  47. Chamary stigers on April 14, 2022 at 6:49 pm

    Fun ride big drone
