On may 10th 2016, my drone did a rth due to a lost control.
He was close to me, something like 50m.

There were some tree above:
Result: crash, destroyed gimball, but my drone rised up again, threw the branches to fisnish rth.

......... here is the mail from dji !!
Much desapointed !!

^since 9.58 to the end, the drone is in rth !!!!!!!!!!!!!!!!!

  

No recovery at no moment

  

  

  

1)87% battery p-gps mode. home point record ok

  

2) control abnormal all the way long. till 09.58, h=5m,d=78m. 45% battery capacity. Why abnormal ?????

  

  

---------------------Note that at this moment, the drone is in rth mode till the end !!!!!!!!!!!!!------------------------------------

  

  

3) 09.58 RC signal lost and drone step into RTH mode. RTH height seting value= 70m, Right, so, you admit that my drone did a rth whereas he was close from me, nothing betwin the drone and the rc !! this drone is supposed to have a 500m range !!!!!

  

  

so the drone bagan to rise up but pilot did Throttle or Rudder input on RC  right (only left stick 1 to bottom

  

  

(the siganl recovery again) totally false, no recovery, and drone continues to rise up !!!

  

  

  

. let the drone fly downward and spin in the air. then the drone went wrong,because of the branches, at this moment the drone fall on the ground (10:06) -à impact and gimball is dead !!!!!!!

  

Please look at the mat and understand that what you suppose is stupid and false.

  

4.40 m/s, whereas the drone bottom normaly at 3m/s

  

  

up once pilot no input on rc. Wrong

  

  

  

  

4) 11.01 H=68m, d=4.1m. drone flew back to the homepoint, began to land.

  

5) 12.05 app recrod stop. h=2m, d=2.5m

  

so viewing from the whole record, the drone behavior normal. RTH fuction works.

  

and the drone did not have a crash. Wrong, crash at 10:06

  

  

  

No please repair my drone and send it back to me !!!

The is the video of my crash.

Dragon, sorry for your loss.
On the other hand I fear I have to agree with DJI: the drone acted as it was supposed to and directed to.Please try to reread the manual and you will realize that this is true.

You need to contact support if you don't agree, also what is your email, date of the flight, and I can look at your flight.
sync the flight records and

it wasn t supposed to lose control 70 meters away from me

Id be interested to see a more zoomed out video of your replay, It most likely lost signal and started a RTH due to trees blocking the signal. Im not what season you were in at the time but if the trees were as green as the video that will most certainly cut out signal at even such a short distance.

You stated that there was nothing between the drone and the RC which that could be true but the branches on those trees extend out into the middle of that road or even past it, so you flying under a branch, signal is lost due to tree being in the way. Drone starts RTH like normal and flys up into tree branch. If thats the case than the crash is 100% pilot error.

set  "hover" on loss of control, rather than "return to home" - NEVER leave that setting as is, if you are flying under. The manual says it, the tutorials say it - once the RTH kicks in, the drone will go up to RTH altitude and there's nothing you can do... Sure there are accidents, but people need to realize that reading the manual is a must.. it does not seem like much, but it really gives you a way better understanding of the functionality of the aircraft, and options you can and should use to your advantage.... Now that I said this.. I better remember myself to do some checking of the options before I fly.. after a while of using DJI and seeing how smart it is, it  is too easy to become sloppy with preflight checks..

I cannot tell from your video, provide your email and I can loo at the flight.
BUT, if the data analysis already looked at your flight record and came to a conclusion then there's nothing that can be done.

Set it to hover? what if you lost control at far distance and you can't get it back?

The hover setting is for loss of signal. In this case,lost signal triggered Rth.If hover was selected it would just hovered rather than climb and hit the over hanging trees.
If hover is selected and you lost control at a far distance,it would then just hover.
You could then press Rth  and wait for it to return.
It's important to change all settings every time you fly to match your conditions and terrain.

Good points Phantomski and Hawks.
I disable Smart RTH when on the boat.  I also set it to Hover when lost controller connection.
RTH on a boat is a horrible idea.
Most of all... Read the manual.

"

I think he means that if you have to fly under trees or something, say an area with a lot of electricity grid, it's better to set "hover".

Well, you don't need to, you can set the home point somewhere on land, assuming you're not too deep into the water (on a cruise ship for example).

And to the OP, please read the manual. Pulling left stick down when ascending in RTH won't land your drone.

RTFM, I with I had a pound for everytime that answer has come up...

Agree, It only limits the RTH height to 20m, and it looks as though it hit the branch at 10m. Personal I never fly under anything just for this reason. And once again we get a thread header stating hardware or software issues, when it's really pilot error.

Its human nature(for most people) to never accept that you personally caused an issue.

the lowest branches were 5 meters above my drone, and, once again, nothing beetween the drone and me,

So if you dont have signal, how does hitting RTH on tx initiate RTH???

Yes you have it. I have it and I have a P3S

Whell you didn t have it the date of the crash.

thank for you help guy......

You're right,dji are clean,

We ll see if you ll say the same thing if you have this kind of issue.

You think it s normal tha your drone make a rth when it is 70 meters away from you .... ok...

Whell now i ask dji to send me the pieces i need to repair my drone,

but DJI add me lot of stuff i don t need and ask me 136 euros to repair....

In france, i bought it 599 euros.

Once again, you think it s normal.

I'am french, so i speak french, no way to find anybody speaking frensh, whereas the commercial site is all in french....

Once again, thank you for your help

Me, i realy think that DJI has a terrible after sale service.
