Seems like maybe you should paint it bright orange before heading out in the snow. 🙂
oh hell naw, I don't want get kill confirmed by a bright Orange UAV
Epic flight! I am planning on doing this one day. surprised i haven't seen this sooner.
Absolutely fantastic video- Thank you.
Great flight!
Fantastic flight :) :)
Just imagine Concorde flew higher at mach 2, while people on board sipping champagne, wearing Saville Row suits
Halo,
what is means Saville Row suits?
@@Bhatt_Hole Saville Row is where the most expensive tailors are in London.
Shocking beauty.
wow, awesome. too bad this wasn't on a 'cloudless' day.
How did you keep the Electronics and control surfaces from freezing up?
Silicon coating. Simple solutions.
And the battery functioning?
@@pcka12 ceramic heater. Be creative bra🍻👌
@@scyonyc your ceramic heater requires electricity to function?
Do you run on Solar panels?!
heloo, można gdzieś się dowiedzieć o danych technicznych?
what video transmission and control module did you use?
Thats awesome. Do you notify the FAA when launching the weather balloon? Or just go to remote areas?
I couldn't stop thinking about the batteries at -60ºC
So start thinking about a PIR foam container. This is the obvious solution to the issue of stratospheric temperatures.
Judging by the moderate stiffness of the entire structure, the ENTIRE hull was made of this foam.
@@andrzej3511 insulation only works until temperature has equilibrated on either side of it, & it has to be sealed against convection.
@@pcka12 Have you never noticed that batteries have internal resistance? They heat themselves. Here, that might be a smart idea, pull Amps and drain that thing, to keep it warm.
@@voornaam3191 now you mention it I do know that (strictly speaking) cells have an internal resistance, so that rapid discharge will create heating, quite how effective this might be I don't know, all of this relates the maxim 'a 10 degree Centigrade/Celsius increase in temperature doubles the rate of a chemical reaction' which is why electrical cells work so poorly at low temperatures - a factor very much effecting electric vehicles.
@@pcka12 As the flight of this plane showed, somehow the battery did not freeze. And I bet dollars against peanuts that no one did any sealing of the battery. Why? Because the battery heats up when under load...
And rather, the battery needs to be cooled rather than heated or particularly protected against frost. I am absolutely sure that PIR foam is a completely sufficient solution in this case.
We've seen solar panels put on the tops of wings, but I wonder how effective solar panels on the bottom of this airplane would be with all the light bouncing off of the cloud layer.
that is pretty awesome
Very cool, I'm guessing its autonomous while at stratosphere altitudes (flying via gps waypoints?)
Would have expected the propeller to be larger given the altitude
I would expect no propeller at all. It can fly for a week, anyway. Why stay up any longer?
what is the wind like that high?
Brilliant!
Łączność z kamerami on-line czy zapis? A jak radzi sobie szybując na dużych wysokościach?
Tutaj zapis, możliwa jest transmisja na żywo. Wszystko zależy od rodzaju misji. Radzi sobie wyśmienicie :)
Awesome!
Amazing
Is that large screen ?
such a wonder
Nice model airplane.
Holy shit surprised this doesn’t have more views
becuase people still think earth is flat, belive that israel is defending itself and elections arent staged. this is a clowns planet. people like scientists in this video are the rare breed
love to do science.
what does this give you that a balloon doesnt?
Do takich lotów trzeba miec juz nadajnik a-dsb ??
"Hey turn around" that's Earth where they are all killing each other!
They call it the Gun Hobby, or something like that. No guns, no killing, but they never got that copied. Stupid, huh?
How did you communicate with it?
It looks like the ELRS radio protocol
1:43 42 hPa? That's about 4% of normal atmospheric pressure here at the surface? That must make the aerodynamics interesting, I'm sure 😊
Nice to see above the jet exhaust plume trails that spread out and block the sun. Thanks.
a flat earthers nightmare, love it.
what 🤣🤣
The Flat Earthers have many members from around the World.
What are you even on about? That fish eye lens curve?🤣 LAMO that’s globehead’s nightmare
Flat earthers make very nice dreams about fish-eye lenses mind you...
Truly amazing how that globe spinning at ~1040mph below the drone had zero effect on the pin point landing.
كيف يمكن للبالون ان يحمل وزن الطائرة
how do you get clearance for that?
Just do it early in the morning 😂
Wow, from space to earth.
Looked like 900mHz antennas sticking out of the fuse.
☠BLACK BARON☠ For such high altitudes ... I presume mHz and not gHz. Well done Techies, communication and battery tech works ... even at -69°C👍
LoRa is incredible
wonder how the GPS signal was lol
Dobra nazwa :)
😉👍
What kind of permission you need?
To go above 400 ft?
@@pcka12 To enter controlled airspace and above.
Are you aware that not everybody has your German mentality? Like, it is against the rules, so you NEVER even think about it? That is very very German. You are like todlers: ah, what they do is not allowed by mommy and dead! OMG! Call the FOO!
Man, they did crowd funding and they BOUGHT that airspace. Yes, billions and billions of bitcoins. Now it is THEIRS, they can legally go to the moon. All airliners and spy planes must ask permission to those two weirdo's. Has it ever occurred to you, this could be TRUE? Your government is strange enough for this. Watch your presidents. Same thing. You all are pretty weird. Just saying.
that’s why he flys while it’s cloudy and also the landing is foggy.
As simple as that
@@pettz18Please do explain a little more
How can a propeller work in the stratosphere ??
Fly is on ~21 km. Kármán line is arpund 100 km. Нe was the first person to attempt to calculate a theoretical limit of altitude for airplane flight. At approximately this altitude the atmosphere becomes so thin that aerodynamic aviation becomes impossible.

@@ivankoval3540 so the propeller is spinning but not doing anything else
@@omarjassar4650 Not. The propeller is spinning and doing good work as well as wings, but not so effective as on the lower altitude.
☠BLACK BARON☠ 1:44 Pressure Indicator
That was awesome to see. I'm not sure if you are from a different country than I am but to pull off a flight like this one would have to have all the "Okays" from the FAA
Or.just do it.../tc
Forgiveness not permission!
That’s a tad over 400 ft.
No permission needed for FL 600 ?
Cool video, unlike the bragging wannabe funny comments down here
solar panels on all the surfases up..
it go way higher then 21 km..
Prodrone dostarcza anteny widzę :)
😮😮😮❤👍👍🙋♂️🙋♂️
Thats where all my data goes ...up in the cloud.... Planes like these do cloud transfer
Кто заметил что в определенные моменты горизонт становится абсолютно ровным?
The curve may be an artifact of the lens.
With the altitude you have …. Why you need a propulsion system ?😝

Testujemy różne rozwiązania, które są odpowiednie dla warunków "bliskiego kosmosu".
Doskonała robota!
A film powinien zobaczyć każdy płaskoziemca!
Where's the dome and the waters above flatheads?
Where is earth curve?😂
@@andreym325 literally in the video you flathead
Was the done over American airspace? If so how did you obtain clearance for such altitudes
Bean dear, seen dad, drone dead. You "gorfot" a question Marx. Hello, you can EDIT your typo.
Antennas from Poland detected!
Oh, look, we can see the curve of the Earth just like people flying on Concorde could so the Earth is definitely NOT flat!
Who knew? 😂👍
With the right lens, and the right angle, even a telephone pole can get curves 😉
@@Vtarngpb
The Earth still isn't flat.
If you watch the video, sometimes the horizon is concave and sometimes it is convex. The curve you see is from the wide angle lense that distorts the image. While the earth is round, this observation is certainly not proof of the roundness of the earth
And the motor acts as charger generator at whilst decending from the stratosphere...?
.
Ooh what a nice ball...
На такой высоте атмосфера разряжена, лопастям винтов незачто зацепиться, какой толк от него
If the wings are working, why not the propellor?
Nie dobrze , na ujęciu ze zwolnienia balonu, widać ze ziemia nie jest ani kulisa ani płaska tylko WKLĘSŁA😮😮😮!!!! No to, żeście teraz chłopaki namieszali 😂😂
Once you go flat.
You never go back.
usually because the meth addiction takes over
This must be CGI, it's showing a round earth 😁😁
I can not see any star.
This is the stratosphere,not the outer space. There are several km of air between.
@@Bonewerkz So...? , I can see the srtas from the ground .
The reazon I can not see the stars is ther Sun light is too strong.
@@mans4104 you need to learn how a camera works
@@evolicious I know how a camera works.Was a trick question related to the moon landing.
No, you still need to learn how a camera works 😂
They used a gas propeller on an electric airplane... I wonder the thought process behind that?
?
Flat!
Show this to flat earthers.
looks pretty 'flat' to me :P
Flat earth Real Yes
How far to the edge? Why has no-one been there, filmed it and proved it?
@josephinebennington7247
Exactly, they see the curve but they just can't admit it and blame the camera lens for bending a straight line but there was a guy who sent up a balloon with two Go Pros equipped with lenses that show straight lines as straight lines and curves as curves and the Earth was still curved much to Flat Earthers' chagrin.
Grammar Real No
😂 lol nope
😮
Look the earth is flat 😂😂😂
Fake! Earth si flat!
🥱
Boże co to za ulep znowu?!
The fisheye lens elastic horizon effect.
Is it a ball from the inside
Is it flat
Is it a ball from the outside
Is it all horseshit
In the old days the " space" was begining At 100 km.... but today its at 20 km... hahaha....
Nice definitely proves my suspicions of how flat the earth truly is ❤🥏
