Incredible Flight Endurance!

I came across this video on my youtube feed today. How is this kind of endurance possible with standard LiPos? The last best flight time of 45 min was achieved by Holger Buss with his hexa mikrokopter if I'm not wrong. Can anybody shed light on how microdrones managed in excess of an hour?

  • - 51 minutes quad flight

  • Still, it's an amazing stamina :)

  • I'm having 15m with 5000mAh 30/40c 3S battery, Emax gt 930kv motors, alum frame and 12x3.8sf apc props. Considering I'm using a cheap battery, if I optimize all this let's say with carbon props and carbon frame removing about 300gr, I guess I could get more 5m flying time, and that's the same time they're getting with 4S, so that's just a matter of optimization and money :)


  • I friend of mine saw one of these quads flying at the Belgian distributor.

    They are €25000-€45000 units. They have large slow roting props and big batteries. This makes them fly long.

    Despite the claims that microdrone makes, my friend wasn't impressed with the stability. When he visited them there was a only light breeze and the microdrone was flopping around quite a lot. They do have excellent camera stabilisation though. 

  • There is always cheating.











    Get a wireless charging pad.

    Hook the charging reciever to your power system.

    Hover over the charging pad.

    Wow look at the incredible endurance!!

  • I expect the model was also a special  lightweight build stripped of everything not essential.

  • Well said Squalish!

  • Here's how you do an endurance 'record' run, in order of importance:

    1) Saturate payload capacity with battery, sacrificing maneuverability, useful gear, and wind compensation

    2) Tune. Test combinations of prop, motor, and battery until ideal combinations are achieved.  Large, slow rotors are preferred.

    3) Run the batteries until absolutely dead (damages them)

    4) Perform the test indoors, where there's no wind

    5) Streamline the frame in vertical airflow

  • No one was questioning them about dropping a battery.  There was just a debate as to if it would allow a longer flight time if the craft was to drop batteries in a similar way to an aircraft using drop tanks.  The consensus was that it might be effective, but it would be over complicated for the application.  

  • as you see in the video, there is no battery dropped from the drone ;)

    and they mein parallel for parallel, not for selective battery switching, that means the lipos are hardwired which menas that all batteries drain at the same time, no empty batteries while the others are still fresh.

    I can't think of a way you could switch between empty and full batteries without loosing power in between (at least not in this power range of a hundreds of watts)
