Help?! DJI already blamed it on me (pilot error) eventhought it was clear that the caused of this issue was a well known bug in dji"s drones that causes it to become out of control, but you all customer support ignored the fact and point your fingers to your customers who spends hard earned money and leave them in the dark with your unreasonable solution when they ask you for help.

Thanks for getting back to us. I‘ve checked your case and video,  please find the data analysis result as below:

1. The aircraft was piloted under GPS mode, and it could not respond to the pilot's control perfectly due to the strong wind, T=00:02, the aircraft recorded the Home Point: 40.7261812 -75.1911785
2. T=01:18, H=71m, D=0.6m, the warning of High Wind Velocity popped up, and at T=15:41, H=104m, D=159.5m, Battery 48%, there was no pilot's input but the aircraft titled -16.0°pitch and -0.2°roll flew away from the home point at 6.8m/s; which indicated that there was strong wind from west affecting the aircraft;
3. T=15:46, H=104m, D=193.4m, Battery 48%, RTH was triggered due to the RC One-tap Return-To-Home, but it kept flying away from the home point due to the strong wind;
4. T=22:00, H=104m, D=155m, Battery 13%, Landing was triggered by the Critically Low Power; And at T=22:59, H=22m, D=155m, Battery 10%, the flight record ended and the aircraft rolled over. The last recorded coordinate: 40.7259634 -75.1893588

In conclusion: No warranty. The higher the altitude, the stronger the wind. Fly against the strong wind, the remaining capacity of the battery was draining faster than normal. I'm sorry that from all the info you offered, it is not a warranty case.

Regarding the video, do you still keep the video cache when flyaway appear? We only found some videos before the accident which can not be verified from the flight records, sorry about this. The designated team will keep follow up as well. Appreciate your understanding.

You just keep repeating old emails sent to me with dishonest solution. Look at the videos yourself and see all my evidence including the actual video footage I took before this happened. Is there strong wind that made the thin branches moved? Did you see that I've flying that day and that was my second battery? If the weather was bad, would I've lasted close to 1hr in the air?. Examine carefully the remote control sticks activities and tell me if the mavic pro platinum didn't flyway itslef and didn't try to regain control of the aircraft but failed. Didn't I use the RTH feature but nothing happened?, instead it kept flying away. At the very end, it seemed to be woken up when it was landing but it was too late for me to control. Now you're telling me it was pilot error and say good bye to my $1,400 plus? Don't bother with you respond if you cannot offer fair results.

I want the smart people here to examine this issue and give me an honest and smart solution unlike DJI who tried to look the otherway.

If you wish us to have a look at your flightrecord you may upload it to this site http://www.phantomhelp.com/LogViewer/Upload/ and share the link with us. You'll find it on your mobile device in a DJI subfolder named "flightrecord".

Looks like you lost it due to wind.  When you went up to 300+ feet, you can see that the wind is pushing your mavic at around 15+ mph.  You hit RTH and the mavic was barely moving and spent all the power trying to fight against the wind.  It clearly seems like an error in your part to have gone up that high and used RTH.  You should have used sports mode in this case.  Wind speed that high can be much different than wind speed at ground level.

You ran it into a tree. It wasn’t even in RtH or moving quickly. You were manipulating the gimbal and sticks at 75 feet and then motor obstruction.

Are you sure?  It says 'Go Home' for quite a long time in the upper left corner?

The low speed could be explaned by this topic https://forum.dji.com/forum.php? ... p;page=1#pid1208862
Although I don't see high wind warnings displayed?

The Mavic landed in a tree indeed, should be able to find it.

You are right, I skipped most of the video. I concur the wind was the issue along with pilot error. It landed in a tree.

Hi here is what you asked for. Let me know. Thanks.

Here is the flight log feel free to review it yourself. Keep in mind that the caused of this issue was it flew away at full speed and it lost control btwn the remote and the aircraft. I tried to regain control by turning off the video and move the remote stick but no respond. Finally, I enabled the RTH feature. http://www.phantomhelp.com/LogViewer/UAVTQ33FPLOJPSN6AICX/

Remember that it started to fly away at full speed that I could hear the motor without my control. I did a couple of things to regained control but no respond. Then I pressed the RTH but it kept flying away. How would that be a fault on my side?

Jeff7577 Posted at 2018-2-25 08:16
You ran it into a tree. It wasn’t even in RtH or moving quickly. You were manipulating the gimbal and sticks at 75 feet and then motor obstruction.

What you see there was at the very end when the machine seemed to finally woke up and gained control back but it was too late. I used the camera to look around hoping to maneuver it and land it in the safe place in under few seconds of battery life but there is only so much I could do.

We can see the entire event in the video. The only disconnection was after it crashed. It flew away at wind speed at almost 350 feet. It fought the wind attempting to come home until it hit low battery and landed in a tree. If you had lowered your altitude and/or gone into sport mode it could have been saved.

When it started to fly but itself away from me I could hear the motor at full speed. It turned around by itself did its thing. I tried the basic troubleshooting while this was happening, ex: video off, remote sticks back in forth, but nothing. I didn't want the aircraft to go even further way and do damage so I decided to press RTH but it kept on flying away from me. The connection continued to be lost until the very end of its battery life and then I got connected but it was too late. Tried to look around using its camera hoping I can land it in a safe place but there was nothing I could do at this point.

You had 40 km/h with gusts up to 67 km/h out of W.

The wind was not the issue. The issue was the flyaway that caused all of this to happened. Here is the video I took the same flight before this happened showing the normal wind condition.

Hi here is what you asked for. Let me know. Thanks.
http://www.phantomhelp.com/LogViewer/UAVTQ33FPLOJPSN6AICX/

More experienced users will be able to tell you more than I can but here is what I see:
All what has been posted here above is confirmed. In addition starting from 3m26.6 you got many "Strong remote controller interference" warnings and connection losses. Have you had bluetooth on or an Apple watch/other device with you?
At 15m44.4 RTH was initiated and AC tried to return home. But it had very low speed only, apparently fighting the wind. It came closer for quite a while but then was carried further by the wind as it looks like.
At 21m58.8 Auto Landing was initiated because of critical battery level and at 22m58.1 it crashed into something.
You should be able to find it. Location is quite obvious and it's not that far away.
In summary the flight record does not show any malfunction of the AC.

Wind was at your location on Dec 25, 2017 at 19:00 UTC:

This is what I can conclude from the this video and also from he phantom log.
You set your low battery warning at 20%. That's when your battery level changes from white to red.
At that time you should really try to bring you craft back.
From your Stick movement you where instead yawing around and moving gimbal.
RTH doesn't look like it was ever initiated. Instead at 13% battery you got a warning battery is just enough to fly back and a RTH was suggested. Not long after that the craft went auto landing
You did not do anything to fly the craft back. No movement on the sticks.
At about 80 ft the craft must've sense obstacle below and was hovering above it. You did not know what to do. You where yawing around and also tried to push it down. And nothing with the right stick to bring the craft closer to you. The whole flight when battery reach low level you did attempt to bring the craft closer to you.
At the at when the craft was hovering the object right before the video was cut out you push craft away from you.
To me this is a pilot error. Sorry

Airdata reports following:

Having looked at your log it’s very clear that wind was your only problem, there are no other warnings, when you hit RTH you can see altitude 400ft approx and horizontal speed 1-4 mph you can see in your video your aircraft being pushed back all the time, it’s very difficult to know how strong wind is at 400 ft, when your standing on the ground, and RTH on Mavic with obstacle avoidance on is really slow and lacks very little resistance against the wind.

If you look at your flight just before RTH you were flying gps and direction you were flying downwind you had speed of 16/18 mph. Now if you look right at the end of your flight you again tried full 100% right stick and could only manage less than half the speed you got flying into the wind. In RTH your speed was between 2-7 kph not enough unfortunately to beat the wind and make it home. Correct course of action would have been shift to sport mode you would then have had the power to get Aircraft home.
Sorry for your loss.

sorry, but from this data for me it was pilot error too. remember, that at 100m, wind can be few times stronger then on ground lvl.
but lets go over Your flight vid:
around 3min mark You 280feet, give full throttle, yet get only 6-7mph = strong wind against drone.
6:40 - on way back (to right side of map) You get from 100% throttle 20-21mph...
10:00 - You try to comeback to homepoint, but all You can get is 2-3mph comeback speed, it goes yo to 10-12mph, but this is only because You also drift up on map.
11:00 - You fight v. hard to keep position, yet still going right side of map even with full throttle = wind is stronger
12:00 - wind gust slows down - You are able to get into home point and land. THAT should be END of Your flight for this day.
yet on 17:40 You still decide to fly more... ignoring earlier wind problems... and go even higher (320ft) so wind will be even stronger...
go even higher - 340ft genius.... and wind push You drone away and away. till it goes out of battery power, auto-lands on some tree.

so yes - in my opinion it's not faulty drone, but pilot error!
1. to avoid it, or for some other pilots reading it. lower your height! ussualy it will get into lower wind zone and allow to comeback
2. bad wind even there - just land it anywhere flat in place easy to spot, (if You got good image transmit). later get it with find my drone/on foot
3. be aware, drone will only flight with limited speed in normal gps mode. there is a way to counter stronger wind - get it into sport, comeback in sport, land, go home!
4. if wind is stronger then even sport mode - say your shiny drone byebye! You are an idiot to fly in that condition, or a very rich man, but then just buy next drone and don't qq.

Thanks once more for your analysis.

Hi.

The way your Mavic flew on shows it did not have the power to overcome the strong wind. If you had put Mavic in sport mode and RTH when it would go home, it was possible it had come home by it self. RTH in sports mode usually speeds up 12-15 km/h because the front sensors are put out of service. I'll guess your Mavic is located where it is shown in the log it's auto-landed.

Learn to take the wind into consideration when flying and fly as low as possible when strong wind is against your flying.   

Regards Leif.

i did not view your logs because it seems everyone agrees on the issue - i will just explain one thing that maybe you did not know (forgive me of you do). RTH speed is much lower than sport mode speed and therefore has less ability to fight wind. RTH is pretty much guarenteed in no or low wind but with a stiff breeze or stronger rth does not have enough power to get home and will become blown away. really hope you find it and that it is a survivor. good luck

I guess that concludes it. Too windy, GPS mode with OA, didn't switch to sport mode, didn't lower attitude and couldn't fly back.

As I mentioned, the video before the accident is not available to be verified from the flight records. Again, the conclusion was based on all the info you offered. If you recorded the video during the last flight as well, welcome to share with us, we are glad to forward to our engineers for review.  

Sorry for your loss, I understand that it must be a sad experience. Could you please provide me with your case number so I can check the details of your case?
