This Drone Can Fly for 24 Hours Straight!

In this episode, the Roswell Flight Test Crew speaks with Christopher McCall of Perspective Robotics AG, a start-up based in Zurich, Switzerland that is developing the “Fotokite.” There are two versions of this tethered multirotor drone capable of carrying a GoPro Hero sports camera. The professional version incorporates a two-axis gimbal and is capable of staying aloft indefinitely using an A/C power source. The recreational version, called Phi, uses a standard lithium-polymer battery and has a fixed camera mount, and can fly for approximately 15 minutes. The flight control system on both versions of the Fotokite is optimized to accept tether pulls as a control input and respond appropriately. The professional version also includes a ground station with a real-time video downlink and the ability to re-position the drone and the camera gimbal.

    wanna give dislike two times

  2. Trent Pettyjohn on May 10, 2021 at 2:10 am

    Drone kite is a really fun idea.

  3. JOSH786MANCHESTER on May 10, 2021 at 2:10 am

    Just fill up a balloon with helium. Attach a camera on it and tie up with a string.

  4. Adam lol on May 10, 2021 at 2:11 am

    This is going to flop quicker than the ps vita. How utterly POINTLESS 😂😂🤣🤣

  5. Doug Johnson on May 10, 2021 at 2:12 am

    Whats really so insulting about this is they probably build this POS for 500 bucks.

    I would rather fly a kite

  8. Wile E. Coyote on May 10, 2021 at 2:16 am

    He blatantly said $8,000!!!!!!!! It’s just a hovering security camera on a leash! People trying to be innovative with stupid ideas. Anyone can make something waaaaayyyy cheaper:
    1) telescoping pole with a tripod base you can stake into the ground
    2) a GoPro Hero 6 or similar quality camera
    3) a mini HDMI cable from the camera to a display at the base, or just use 5.8Ghz VTX and receiver
    4) rig the camera so that you can provide constant power to it from the ground

    Boeing and Airbus are looking for the blueprints of this…

  10. Barbu Vulc on May 10, 2021 at 2:22 am

    GREAT. 💯
    BETTER than using awful batteries.

    The title of this video is misleading.

  13. paulkazjack on May 10, 2021 at 2:25 am

    Tethered?? Erm very very single use application.

  14. Sebastian Gil on May 10, 2021 at 2:25 am

    How about a balloon… since it needs to be held thr whole time anyway

  15. tharun narayana on May 10, 2021 at 2:27 am

    I am from a computer science background and I don’t have much knowledge on electrical and electronic things.
    I have drone which was built by assembling all the drone essential requirements.
    I have a battery which is 5200 mah, 11.1v 35C. I think I can continuously fly the drone for 10-15 minutes.
    Now I am thinking of another power source , which is tethered drone. I don’t mind drone tethering
    I have an idea in my mind to build the tethered drone. I am not sure whether it will work for me or not. Please help me on that.
    On the Ground I use AC power supply which is 230 volts and use some 14 – 22 gauge wire for 100 feet and at the drone end convert AC 230 volt to DC 12.5 volt. I mean some kind of adapter(AC to DC , 230 volts to 12 volts 1 amps) I will use. Now I am worried about is the amps which is required by the drone motor. I have a 180000uF 50V Electrolytic Capacitor which weighs about 700 grams. So when the capacitor gets charged from the source side and discharges at the other end.
    Will the discharge side able to run the drone motors? Please help me on this.
    And I also have some super capacitors, Can I use those capacitors.
    I am providing you some link on the capacitors which I have already purchased.

    $8k??? For only a little bit more you can get an Inspire 2 with a tether, and you could live stream in exponentially better quality than that thing.

  17. Bob Keller on May 10, 2021 at 2:28 am

    Why are you dressed like your going on a safari when you interview? And…what is the patch on your left arm?

  18. Jiseon Kim on May 10, 2021 at 2:29 am

    What the hell. Hoax! you should change the title.

  19. Hayden Boyer on May 10, 2021 at 2:29 am

    Or use a stick

  20. Joel H on May 10, 2021 at 2:29 am

    we need a solar drone … this drone is like a kite lol

  21. TheDroningPreacher on May 10, 2021 at 2:30 am

    You could pay 8k for that piece of hot garbage OR just rig up a power adapter for an inspire 1 with 100 feet of wire for 50 bucks. Let’s do some math here…

  22. Jimmy JAMES on May 10, 2021 at 2:33 am

    yep, $8K for this, insane!

  23. vikram raj on May 10, 2021 at 2:34 am

    Umm 8000 cents is ok price for this garbage 🤣

  24. Stephen Peters Aerial Photography on May 10, 2021 at 2:34 am

    So why not just attach power cables to any old drone and do away with the battery. The higher you go, the heavier the cable. So this thing is utter crap unless you launch from right where the action is… plus no GPS, which means in anything other than a dead calm day, this thing will be buffeted around like a swing ball. No… No, absolutely not.

  25. Bachelor Frog on May 10, 2021 at 2:34 am

    better this thing was wirelessly powered.not bad.

  26. Owen Walters on May 10, 2021 at 2:37 am

    So you can fly for 24 hours but I can’t fly 2 miles away like the phantom 4.

  27. Mitchell Peterson on May 10, 2021 at 2:39 am

    8 grand?? Dream the eff on. The consumer unit is little more than a toy.

  28. KITSUNE Fpv on May 10, 2021 at 2:40 am

    Wait what? Then what about the esc and motor overheating?

  29. Owen Walters on May 10, 2021 at 2:41 am

    And the consumer drone looks like a toy.

  30. dimitrimoonlight on May 10, 2021 at 2:41 am

    I’d pay €50

  31. Dan Elgaard on May 10, 2021 at 2:41 am

    The tehtered one looks interesting, but what is the flight altitude?

  32. NAVEEN M on May 10, 2021 at 2:43 am

    1month stay drone how to buy

  33. RAiNblasst24 on May 10, 2021 at 2:44 am

    Did it have a video output for video mixer ?

  34. Red Alpha on May 10, 2021 at 2:45 am

    It’s as useless as an iPhone… It can stay charged too if connected to the wall charger… Same price and both are useless at the field. Sorry I’ll pass on this one…

  35. Elbow on May 10, 2021 at 2:46 am

    How do you swap batteries out in the field without dropping the drone?

  36. Mitchell Peterson on May 10, 2021 at 2:47 am

    Crap in a tube. You can’t polish a turd!

  37. Mark Scott on May 10, 2021 at 2:47 am

    8k for 1080P? PPPAAASSSSSS!!!

  38. Monoblock Adi on May 10, 2021 at 2:49 am

    a rod or a relatively large balloon can do the trick

  39. Jimmy JAMES on May 10, 2021 at 2:49 am

    Isn’t this $8K?

  40. Screen Apple on May 10, 2021 at 2:50 am

    Will TV news get job like Drones Cam?

  41. blue280485 on May 10, 2021 at 2:52 am

    FotoKite ground station could be plugged into a Portable Inverter Generator like Generac iQ2000, this way it could be possible to fly it off grid in remote locations!

  42. SAMITH RAO on May 10, 2021 at 2:52 am

    Excellent work !!
    For long duration surveillance, you can look into power tethering solution.
    You can look out at these guys they are with power tethering for mavic 2 pro.

  43. nmsidewinder on May 10, 2021 at 2:52 am

    You have got to be kidding ! Anyone with any DIY could make their own with any decent priced quadcopter that has strong brushless motors on it. What a joke.. lol I wonder how many people bought one of these and did they feel their change hit them in the back of the head as they walked off. lol

  44. Whymehh on May 10, 2021 at 2:53 am

    O its called a cable drone btw

  45. DAKTiger1 on May 10, 2021 at 2:54 am

    I could wire up a drone with a long power cable connecting to a voltage regulator and power it up from a wall outlet. That won’t cost me more than $50USD + cost for a regular drone.

  46. Skyblock Veteran on May 10, 2021 at 2:57 am

    8000?😂😂but I can buy 100 spare batteries or 10 more drones or make same system just for a couple hundred bucks

  47. Scott Marshall on May 10, 2021 at 2:58 am

    Powerloops are hell…

  48. BABYLON on May 10, 2021 at 3:03 am

    So what’s the point? It’s plugged by cable

  49. Doug Johnson on May 10, 2021 at 3:06 am

    My goodness the price is laughable, 1080p, I wonder how many they have sold, lol zero I am willing to bet. 8K dollars that insults my intelligence. WTF

  50. The Bread Thingy on May 10, 2021 at 3:06 am

    GTFOH!!! That’s Super Whack and so Not Need for a single thing in society. Unless u have a buncha lizards on board who wants to climb down.
