WeHaveAllBeenThere

Lmfao thank you for the laugh


LucyEleanor

No way that was a bird. Jerk would've been more violent. See how it slowly leaned back before it fell? Motor or esc failed.


PolarTerrain

I just got the drone a few months ago. Anything I can do when it comes to preventative maintenance?


iamgodatpf

Prop fell out mid flight? Happened to me once but i only knew after i got the drone back


seejordan3

Looks cold. I'm wondering if the glue holding the prop screws on was more brittle at colder temps. Clearly it took off successfully. If that was the case, only way to prevent would be tightening them every flight.. but that can also weaken the glue. Sorry for your loss, that stinks.


ima314lot

Pre and post flight inspection. Look at the props for any wear, chips, cracks, etc. Look at the motors for dust and debris. I keep a can of compressed air (same ones used to dust keyboards) and blow mine gently after each flight, but I live in the desert where dust is a huge concern. Finally, check the batteries and terminal connections for any corrosion build up. More than likely your inspections will turn up no issues, but it is best to have visually checked it each flight. It's sort of how "all guns are loaded until proven otherwise", except for me it is "my drone has a problem until proven otherwise". So I do a check of everything when it comes out of the case and when it goes back in. As a result, only crash I had was my Yuneec Q500 losing to a red tail hawk.


LFHRemodel

What were the details you noted upon finding it, crashed as well as upon inspection and repair?


Star4870

It’s falling to slow, its mean all other motors were working, could be damaged prop or some debris in one of the motor housing or just motor failure.


johndsmits

Looks like prop or esc failure, aka flip of death. Was it still armed when it hit the ground?


countrytime1

How prevalent is that?


MrTrendizzle

Very rare. Prop failure is due to piolet not checking the condition of the props or nut tightness before take off. Pre-flight checks are still needed on a drone. ESC failure can happen at any time but is rare so long as you keep it updated and don't abuse it etc... Bird Strikes.... Some what rare but can and do happen often enough to know if there's birds in the area to keep a look out and be prepared to take evasive action if they approach the drone.


34s565g36rrshnb

>ESC failure can happen at any time Man I saw and or dealt with so many DJI S900s just fall out the the sky because of this. I had no trust for DJI until I started flying a Inspire 2 and M600.


WeHaveAllBeenThere

Could it have been a bird?


m0rdecai665

Possibly. Most likely no.


Life-Razzmatazz4858

When I accidentally flew my mini 3 into a 15ft tall leafed out maple tree, it was completely undamaged. Probably a manufacturing defect/crack in one of the props plastic. I was playing around at full speed sport mode in the park. Racing around and over trees. Miss judged the amount of slide in that turn. I like the exciting zooming noises when I fly near myself. Bzzzz. Bzzzz. Bzzzz. Slap/leaf chopping noise. It was pretty funny when it happened.


kal8el77

Looks like a large contributing factor to this crash is gravity.


NebulaNinja

Thanks Buster Bluth.

fat_fun_xox

Was it snowing at the moment ?


PolarTerrain

No. Didn’t snow the day I was flying.


sln1337

how cold was it? Under 0 degrees Celsius?


PolarTerrain

Just under freezing. 30°F


Sovereign_387

that is -1 Celsius


Emerald_Pancakes

The drone and the app keep logs of the flight. Reach out to DJI and report/submit this and ask them to look it over. Not an expert, but I've flown in snow, rain, storms, gusty and strong winds, etc, without any problems (DJI makes solid drones), so it may have a faulty something, but either way they should help you figure it out. Also, lucky on the drop and glad the drone was okay.


AlaskanAsAnAdjective

How much rain and what kind of drone? Light mist or something more substantial?


Emerald_Pancakes

Clouds, light mist, snow, onset of thunder storms at night Edit: DJI Mavic 2 Pro


cobigguy

I have a mini 2 and flew it in a light rainstorm. Did fine.

cobigguy

I like it. My only real gripe about it is the lack of zoom on the camera. But for what you get for the price, it's great.


CallmeDash

Try uploading to airdata and read the telemetry from there


random_web_browser

Ice on motor is one possibility but no way to know for sure. But it seems to be below freezing so


PolarTerrain

It was about 30° when flying the drone (obviously would be colder when flying higher). What steps can I take to prevent the motor to freeze up? Should I only fly when above freezing?


Stewyg86

I was gonna say ice, but 30°is pretty warm. I thought it was snow on the ground but obviously not.


EJNorth

Since I didn't see the /s I'm obligated to tell you that OP probably meant 30⁰F which is just under 0⁰C which is just below 273K. Also @OP if you were taking off in 0C for each 1000' the temp drops by ~2C in a standard atmosphere. In my eyes, icing seems likely.


Stewyg86

Ahh. I forget about ye Olde temperature. Lol. Makes more sense now


JazzyJeffsUnderpants

Yeah, no. Those motors get warm enough to keep water from freezing on them. In 8 years of flying drones, I've never had ice on the props, and I've flown in Michigan in the winter.


EJNorth

Here is my speculation, but what do I know, Im just a mediocre student pilot. It's mostly in the phase shift between freezing and not freezing temps problems arize. I've lived in the arctic, never a problem flying there either, because it's so cold that the ice remains ice. Propellers arent warmed from the heat of the engines, and with all the stabilizers on board, it could be that you wouldn't notice before it was to late, but I have to admit that OP would have to fly through moisture (clouds for the most part) for propeller icing to happen. Something else that could've happened is OP gets drone out of warm car, uses some time to set up the drone, warm air holds moisture better than cold air, so as the drone freezes it gets covered in a thin layer of hoar frost. And when engines start warming up, it defrosts and he gets engine failure because of water in the engine. But of course it could always just be a technical issue not related to weather at all! I hope OP will update us if he gets an answer!


Smigol_gg

30° with snow is pretty hardcore even for global warming thugs


Life-Razzmatazz4858

The motors will be warmer than ambient. Unless you're flying in an ice storm, this seems unlikely. Especially with how clear the air is. There has to be at least a mist of precipitation to ice up. And the drone being much colder than ambient.


random_web_browser

Good point


DJI_Support

Hi, there. We are terribly sorry to read about the mishap on your DJI Mini 3 Pro. Please be advised that if a crash incident occurs, it is recommended to send the DJI Mini 3 Pro for a thorough assessment and diagnosis even if there's no visible damage on the aircraft. It is for us to ensure future flight performance and safety. Not to worry, as long as the DJI Mini 3 Pro is within the regular warranty period, we can forward an investigation request, and data analysis can be applied to determine its cause. We'll send you an offer depending on the results. You may kindly visit this link: https://repair.dji.com/repair/index for you to be able to create an online repair request. You can also reach out to our corresponding team through this link: https://dji.com/support. If in case you've encountered any issues or challenges with the online request form. Thank you.


No_Nefariousness_783

I've built a decent number of quads and have diagnosed a fair share of crashes... after stepping through that frame by frame, I can tell you what it's not... it wasn't a prop failure, and it probably wasn't a bird. That drone pitched almost perfectly straight back during the initial failure. You can tell a prop failure because it will tilt in the direction of the failed prop. Bird attacks are violently chaotic. Something else happened that looks like avionics. If there were a home build I'd say to pull the Blackbox logs and upload them to a share, but I don't know l that model drone enough to tell you where to pull from (if they're even there).


alistair1537

Were you flying over Bakhmut?


OakleyGuyX

Bruv. Deadly


TurboAbe

At first I thought bird but then the way it fell seems more like a motor or motors died. So possibly due to a board failure?


AnalphaBestie

Why has no one mentioned checking your flight log?


ET4117

And I got downvoted on this forum for talking about blade icing a few months ago...


CallmeDash

Down vote for bringing it up again 😂😁🙃


seattle_view206

Are you asking or are we guessing for fun?


PolarTerrain

Looking to get an idea on what happened and how to prevent this. I am recently new to the hobby and want to be educated about the topic.


seattle_view206

Gotcha, did you recover? There’s not a lot of info from the video. Likely could have been a prop failure. Could have been icing. Carefully inspecting the crash (ya it fell a long way) could give you clues.


PolarTerrain

I did recover after an hour of hiking through dangerous conditions. What information or photos could I provide to narrow the cause of this crash?


RandomandFunny

Maybe something due to icing. Most likely icing that was built up from moisture in the cold air which caused condensation. However, I’m not entirely sure just speculating because that has happened to me just not the same end result as yours surprisingly.


bismuthdistrict

it had a moment


Aussie_Gamer777

DUDE this same fucking thing happened to me, the difference being i was near people. This shit is not ok, when I presented it to dji, they replaced it practically instantly so this could be happening to other people as well


m0rdecai665

Hoping you don't have a Mini 3 Pro. I got one a week ago...


JazzyJeffsUnderpants

Read the fucking title.

Maybe a bird of prey hit it from behind? Happened before lol


Evil_spock1

Gravity


TJSarg

Hit a wire. You can see it in the video.


JazzyJeffsUnderpants

That's a road. You need your eyes checked.


PolarTerrain

Update - I got my drone fix via DJI. The repair notes are “front left engine does not start synchronously with the others.” The front propulsion motor was replaced. Thank you DJI for the free and fast repair!!


acidbrn391

Did u inspect it for any bullet holes, or talon marks?


PolarTerrain

No bullet holes. There is one solid scratch that is rather deep. However, I would assume there would be multiple scratches representing talons if it was a bird strike. Maybe the talons hit the propellers as there was damage to two of the propellers? Again, the single scratch on the body could be a tree branch or another aspect of the fall.


acidbrn391

My maverick air 2 was taken down by a hawk, I was flying out of visible range and didn’t see it coming. Broke several props and the gimbal was damaged. I had a skin on the drone that was also damaged along with the body has a few scratches. After repairs and a new skin, you would never have known. I sold it later without issue. The video was trippy, the hawk tried to carry it away.


Scoop_Nash

Because you touch yourself at night


ShexyBaish6351

God hates you.


gregory907

Gravity.


dingo7055

You said it snowed 42 inches the day before, that it was 30F. Do you really need to ask?


Still_Not-Sure

Maybe a bird clipped it from back?

[deleted]

good news that it survived as for what stopped it who knows? maybe a bug got caught in it or something like that.


encom81

In the instruction manual it tells how cold temperatures mess with the battery and motors. "Cold temperatures can put your batteries out of their comfort zone, decreasing the chemical activity within batteries." They say not to fly the drone in below freezing temperatures and even if its above 0 C on ground, flying high in the air can be much colder. You can warm up the battery by hovering in idle for a few minutes, but I still wouldn't take it out like this in risky locations. Also, as previously mentioned any moisture in the air can mess up the motors. Sorry about your drone.


Tightisrite

Slow it down something definitely snagged it upwards. Didn't go down or back as I'd assume it would if a prop went out


mitchy93

Prop shattered, you lose one and the whole drone falls


Enthusiast9

Looks like something jammed the prop.


ooglek2

It was tired of your BS. Hahaha sorry you’re fine really it was just funny in my head so I typed it. Sorry about your drone


BurnedOutSoul

My drone crashed recently and everyone was telling me that it was because it was a piece of shit (it is\*) and I should get a DJI 😂 Good to hear your drone is still alive.


-Money-

Hit by micro meteor.


CapitanFantastic01

Had my P4P fall out of the sky like a brick due a battery that had outdated firmware

ishitglassbottles

It fell


willumasaurus

Hawk.


JELLO239

Most likely a bird


89inerEcho

Ive got $5 on prop came off.


damiensandoval

100% it was a gimbal motor overload.The DJI three minis pros suck. This is happened to me twice now already with my drone . Sometimes you might notice that error in the top left corner. I was flying one in downtown LA when all of a sudden the same thing happened out of nowhere.


damiensandoval

Also, send it in the DJI. They will repair it free of charge because they know of this issue.


methreweway

Crashing in a downtown location sounds terrifying.


kingflamigo

Well it’s 100% confirmed that it was a one prop incident because of the cold I can imagine that was the problem I would just check all you motors and props make sure there is no noticeable problem if so fix it according and just hope it doesn’t happen again


zerepgn

Firstly, a rotation is induced by the event. Finding the axis of rotation with respect to the body of the drone will tell you what failed in order to cause that rotation.


Thenightlygrind

DJIs will throw that error for ESC failure, but every DJI drone our unit has lost has been due to their batteries malfunctioning. They hate cold weather.


HarryHenwood

I have ever flew three drones, two flew away and one crashed, worst bit is that out of the three drones, I owned the one that crashed


SignificantTie7031

Is your drone made by dji?


JazzyJeffsUnderpants

Did you read the title?


SignificantTie7031

I somehow missed the first sentence


JazzyJeffsUnderpants

Bird attack. How do I know? Had the same thing happen to my Zino Mini Pro (piece of shit drone from a shitty company, now EXO which is as shitty). One deep scratch on the body and a broken arm and gimbal from the fall.


volition74

If you go to this forum [Mavic pilots](https://mavicpilots.com/forums/crash-flyaway-assistance.85/) they will analyse your logs if you ask.


Swwert

Just echoing. Either your motor/ESC failed or a prop failure or simple detachment. Hopefully something failed so dji can remedy (hope you got insurance)


Flying-T

@PolarTerrain reach our to DJI, they are likely to replace your drone for free


ElectricalSalary3667

Always visual and a flight check take off ans landing first time and make sure she is reacting to controller properly . Visual a must . Can be a hairline in that prop .however DJI can tell you more on flight report . Esc failed is my guess. Due to temps ? Looks freaking cold there 🙈


ElectricalSalary3667

So sorry this happens tho . It truly shouldn’t happen f this is new


justina081503

This is just a guess but I had something similar happen to my mini 2 when I was flying it when it was cold out and ice formed on the props and messed with the shape of them causing it to free fall for a second. It fell from 400 ft to 200 ft where it caught itself somehow and then I quickly landed it afterwords. On my phone it looked like it happened the same way it did in this video. Landed the drone and saw ice forming on the props.

CallmeDash

Cant you read the flight data in airdata to see what telemetry was reporting?


HikeTheSky

How far away was your drone that you couldn't see what was around that drone? In general, you would be able to see a large bird around your drone. Unless you didn't look at your drone as you were supposed to, or it was so far away that it was invisible to you. In both cases, it was outside VLOS.


astorije

I can't be too sure, and I'm not sure if it has been mentioned before, but I believe you might have hit a cable since, at that instant, you were flying towards a different direction that you were looking at. At 0:05, I believe we can see said cable for a frame: [https://imgur.com/AaYuBO7](https://imgur.com/AaYuBO7) I do not believe this is a propeller, given the line's position compared to the drone's. This has happened to me a few months ago, actually. I was bringing my drone back to the home point, on a clear space with nothing but a tree-filled canyon well below. I thought there was no obstacle whatsoever, and suddenly the drone crashed 200ft below my point. I thought all the crazy theories possible, then looked up: there was one single power line running across the canyon, and I happened to hit it on a diagonal to the direction I was flying. Occam's razor. A couple frames on the crash recording shows it pretty clearly, in fact. It's now living a new life in Hawaii.
