Wow wow wow, absolutely kudos to you for putting your drone in the position to show others what can happen and for others to avoid. Great educational video as usual 👍
I encountered this phenomena here in Austria in a region which is known for its dense fog. First I lost thrust then the motors stopped and the drone fell like a stone into long grass.
If you wipe your props with rain x nothing will stick to them including ice!!! Try it and you will see it works!
great tip thanks
Today I carefully flew the Mini2 in freezing fog conditions. The drone didn't want to land. I guess the drone recognised the clouds below as ground. Luckily at a certain moment it come down again.
The icing and the ' max load ' caution were exactly as you showed in your video. It was a good experience!
You rock. Thank you as always for amazing content.
Another great video - Henrik 👍😀
Great stuff thanks!
Great video - I’ve only ever had problems once in fog and never since as I don’t fly in it anymore - was my m2p and nearly lost it
Amazing!!!! You really go extra mile for making amazing content, Henrik! 🤩👍🏻
I personally love flying above the fog, so this is very useful info!
Yes, I’m curious of nature so I guess that helps
😱👍. A great and very important experience indeed. At least we know what to expect from icing on The propellers.
So glad it made it back home. And no damages to the motors.🙂👍.
Thank you so much for sharing this video and God bless. Have a great week everyone
Great review and test. 👍👍✌️
I’ve never flown in that know of weather before. This is great information to know as it’s not something most people would not think about. I would have figured the ice would have built up on the back edge vs the leading edge.
I have had this happen with my P2 vision plus years ago. The flight issues started only when one or more blades started to fling off the ice buildup causing an imbalance in performance between the rotors. Luckily it was not at a very high altitude. Scary stuff.
another great test video from the master. Thank you. I was about to fly with the same condition but I have watched your video first so I deferred.
yes you need to careful
YES! Exactly. I experienced this with my Autel EVO II Pro. Flying on a cold, foggy morning, after a few minutes I got to the top of the fog, panned around a bit and started a Hyperlapse. Then I got "High Battery Temperature, flight performance limited" warning and so I decided to start back down. Then a few moments later I got "Battery Overheated" and "Critical Low Battery" and the drone came down rapidly right where it was. All this within 5 minutes in the air. It landed in tall grass and there was ice on the propellers. Fortunately, no damage. Whew! The extra load on the motors due to ice build up on the blades overheated the motors and rapidly drained the battery.
Thanks for bringing this up to your viewers.
No guts no glory 🤣
Amazing how fast the ice can build.
Thanks for showing 👍🇨🇭

Just have to put some (pg) Propylene Glycol on your props and your ready to fly in all safety
Ah the icing problem. Knew that since iron man 1.😉
Yeah, it happens in snowy conditions too if your drone runs hot.... Had my fair share of "we must use attitude mode and land manually the hard way" .... quite scarry with an expensive drone
Great testing! I think I'd just stay out of the sky in light of this if I had those conditions. Nothing I film is urgent.
Never been a problem in Sydney Australia!
Super interesting 🤟🏼🤟🏼
To get a drone pilot certification in Canada, ice build-up on an aircraft's props is a section covered in the exam. It would seem this is why.
good know it's part of the material - it's not in denmark
Same thing happened to my mini 3 pro, my drone was about 600m away from home point when I got the first “motor overload” warning. Luckily, I was able to bring it back safely at full throttle. This would have been a devastating loss since it is my replacement drone that I payed out of pocket due to a previous incident. In short, don’t risk it!
A good thing to avoid this, is to dip the propellors into some baking oil or butter, so the water does not stick to it.
Nice of you to test it out for us 👍😀
my pleasure
Happened to me on my first mini. It dropped from the sky as you said. Luckily it landed on grass. No damage
Darn it. We will now need to develop heated drone blades. 😊
ha, yes = short flight times
You can still fly with perfectly flat non airfoil props or props that have some blades bent up 90 degrees you would be surprised how much the flight controller can compensate for
Nice tips ❤️
Thanks for the video. I had the same problem with frozen props. Error received was: "Aircraft max power load reached, decrease altitude" at less than 20m. If you see this or any motor alarm in low temperature conditions, get the done back immediately and low as you can. Do not use RTH as it will potentially cause accent making it worse. Went from warning to fall from sky in 20 second's. I got lucky, landed in a soft field with no apparent damage
Yes, this issue is very real
Including part of your comment in my Emergency protocols...👍
I don't how many air disaster shows have touched on this subject. These are just smaller than a commercial aircraft, the same weather rules apply with regards to poor weather conditions, especially in freezing temps.
Ran into this problem in Canada in a similar situation. Luck for me it was a short and straight up flight. I was up maybe 8min in total. Ended up having to wipe the blades. Not recommended. Managed to get some cool pics in the end.
it can easily go wrong
Being a former pilot, icing is well known. Flying my drone the fingers get "iced" when it's cold.....
Being low on battery, is sports mode the most efficient mode for distance versus battery usage?
Aerodynamic is same for planes, drones or heli... This is why planes have de icing systems. In case of drone you could expect that centrifugal force will solve the problem but seems like not - I guess using on rotor blades sort of hydrophobic layer would help a lot. Guess even ordinary car wax could help already...
Helt fantastisk video, (kan ikke bruge den til noget når man bor i Sydfrankrig) men nok en af de bedste demonstrationer jeg har set i lang tid 💯
Tak Peter (lidt heldig har man lov at være)
Hello 👋
For the fog to appeared, you need to be in a No wind condition. So it’s a very stable air mass.
The layer close to the ground contains more moisture than the one on the upper side of the mass. As the altitude rise, the temperate degrees, a normal rule under, except in a temperature inversion situation but that’s an other subjects. So you will think by lowering the altitude you will be in some warmer temperature and hopefully out of freezing conditions. That’s a good idea … at first !
In a contrary if you go higher the temperature will go down and you will be even more into a freezing conditions where you do not want to be …. Maybe you do.
As you Clim you will get out zoner from the height moisture layers and even out of it, All that dépende of the thickness of the fog you are in, but no moisture situation is what you are looking for. It will not take raid off the problem but at the least it will not get worst.
The number 1 rule is to get out of visible moisture !
All fogs do not touche the ground , radiation fog does ! But that’s an other subjects too.
It is a very complex subject the formation and disparition of the fog. It is beautiful to witness because been so close to the ground, it makes it so well visible for us all to watch.
Take care a be well.
Great supplementary information :-) I learned a few things from this :-)
I lost an DJI Air 2S in freezing fog. I got the message "Motor is Blocked" instead of "Max power load reached". The drone fell out of the sky immediately. DJI was kind enough to cover it under warranty.
Wish I would have known about this phenomenon before I took my drone out this AM. I never would have gone out to fly. It was foggy and about 21F (-6C) this morning after a good snowstorm yesterday, so I figured it'd be awesome to head up the canyon and film the river and all the fresh snow on the trees, paths and bridges. The flight was going great and I was only about 0.3mi (0.5km) from my drone in fairly dense fog. After only about 5-6 minutes of flight, I was getting ready to spin the drone back around to come back to me and it suddenly fell out of the sky into the snow! Fortunately, I was able to somewhat control it sideways so it didn't land in the river and it had a relatively soft landing into the fresh powder. I couldn't believe it when it happened!... Still can't, really. No warnings on the screen or nothing until the propellers stopped when it hit fell into the snow! But this totally makes sense if there was some icing of the propellers, which caused it to fly ineffectively and not generate enough lift.
Thankfully, I had just gotten my footage of the small waterfall before I had gained altitude to spin it back around to come back, because otherwise, it would have landed right in the river. I called DJI tech support after it happened thinking it may have been something defective with the drone for it to dive out of the sky like that, since I was operating under the correct temperature conditions and distances. I explained the conditions to the guy I spoke with on the phone, but he didn't mention this particular phenomenon and may not even be aware this can happen. He was able to pull my flight data and get a case entered for me to escalate it further. I suppose they'll review it and see if it's worth replacing if something's faulty with it. Fortunately, everything still seems to be perfect with the drone since it was a nice soft landing in the fluffy snow. Even though it was an awesome idea for some footage, I definitely won't be doing anything in fog and sub-freezing temperatures with the drone again! Hopefully my story can help some others avoid an issue too. However, it's likely they'll be like me and find this video when it's too late. Hopefully, they won't damage theirs too badly either! Thank you so much for your video and the explanation!!!
I wonder if coating the props with wd40 or pam to prevent precipitation build up help
I think it could
Hope you have your DJI Care up to date.
Interesting, however i would never fly in those conditions.
Just an add-on to last comment, I have also wiped props with hand sanitiser with high alcohol content which also is quite good.
I believe this device does much better on the cold then the heat
Any chance for fcc hack ? All old tricks not working on mavic mini se
Drone hacks
Interesting things happen when we mess around in mother nature's space. I learned about this icing stuff while flying IN real aircraft. Basically when aerodynamic structures stop producing anti gravity, gravity wins. Do not fly over water in thick freezing fog. Why would you? 🤪
it hapend to me as weell
Looks like I'll be the first to mention that drone flying in fog is not legal (in the United States). Where's your 3 mile visibility and distance FROM clouds? None and zero. When I first obtained a drone, I flew straight up in a fog hoping to pop out on top for a glorious view; never found the top and nearly crashed the drone. Relatively thick ice had formed on the propeller blades in just a couple of minutes and not just on the leading edge; where it really matters is the upper side that creates low atmospheric pressure and thus also reduces temperature. That's where the lift-killing ice forms and changes the shape of the blade; it is no longer an "airfoil".
Have To Oil Your Props Before Flying In Fog Bud LOL
Hi, TDM
watch out for WATER WAPER !!
Had the same today after about 3 mins - my advice - do t fly in freezing fog 😂
True it could very easily go wrong very fast
It happened to me as well. At the same time. It fall down and crashed. I wonder if warranty will cover that. I had no I idea about this weather condition not god for drones
@@mantealis I managed to land mine safely. Suspect manufacturers will not repair/ replace under warranty as it stats in manual not to fly in those conditions!! As everyone says - read the manual !!!! Hope you get it sorted at reasonable cost
Hey! Never use metal surfaces to take off! Maybe you will get compass error and can your drone fly without control!!! Nobody try this, Clever people don't use car's roof to take off his drone!
Ehhh it’s a glas roof
@@TECHDRONEMEDIA but nearby there is metal. You should not take off next to metal surfaces. It is better to keep 2-3 meters distance.
Hi buddy, I give my props a wipe with WD40 and that gives me a good chance of staying ice free for a good while.
Without conformal coat protection, you're kinda asking for trouble flying
So....if the FREEZING FOG has clear space over the fog up to 120m AGL can you fly? Edit - An afterthought for you, that would not provide VLOS, would it - End Edit
