Forum fam.  Just got my Phantom in the mail 1 hour ago.  Did all the standard configs, Firmware update and all working well on inital flight.  On second flight Phantom powered down at about 80 feet and crashed, totally destroy! (*&^%$#$!!!!)  I have yet to activate my DJI care, but it's still under 1 year warranty.  What are my options?

By the way, I am not a newbie to DJI drones, Currently own I2 and Mavics, first Phantom 4 though.   

Can you upload the flight log and post a link to it here please.

Without the log there is no way of telling what happened

Will do thanks !  Give me a sec

If the log shows it to be a malfunction with the drone then you should be covered by warranty.
Either way you will need to send the drone back to dji for repair

Sorry uploaded a log from two days ago.  Just uploaded the log from today.  It was the second flight as I described in the post.

I can see the last entry in the log shows the Phantom @

8m 35.2s        Sport        21satellites        143.7ft        N/A        22.5mph        169.6ft        60%        14.989V        3.746V        3.755V        3.752V        3.736V        0.019V

This is the point at which it simply powered down and fell.   

Can you post a link to the flight log here please

Ok not sure whats happened but im sure once our flight log gurus have a look they may come up with some answers.
Im curious as to why the log has started at 3.5 minutes tho and why the battery hardly lost any power while flying in sports mode.
I recommend waiting till one of the other guys looks at the log file

How tall were those trees where it fell?

How tall were those trees where it fell?

Thanks.  The trees are about 100 - 120 ft.  Did not fall by the tree though.   Loss power and crashed on the way back just over the house adjacent to the tree line.

Hi, I'm sorry to hear about the accident. Please kindly contact our support to start a case and send it in for diagnosis: https://www.dji.com/support. If the drone is still in warranty period, the local team will arrange data analysis after they received the package. If you encounter any difficulties during the repair progress, feel free to contact us with your case number, we'll be here for help.

Thanks for the feedback Diana   I have already put in a support ticket.    I will keep you posted.

Not a betting guy but, last recorded position was at that tree,  in sports mode,  at 22mph,  your guestimate of the max tree height is only 20ft below  your drone height, inexperience of the ac is perhaps whats led to this? a bit like me trying to go under a wee bridge, but hey, this aint about me ;)   Your flight stops at the tree chap

That's the weird part,  I did not go down by the trees.  I was on the way back from that path which was not recorded for some reason.  The drone actually loss power 1/2 back from the trees just over one of the houses.  X in the images is where it crashed.  I have over 250 hours flying DJI drones and have never seen this happen.

looks to be well above the trees

[view_image]

It was at least 20 - 30ft above the trees;  This is my neighborhood so I often fly this route during initial flights or after making any firmware updates.  The Phantom actually loss power and crashed some distance away from the location depicted in the logs.   Frustratingly weird.

Fair enough, looks like its down to DJI to ascertain the malfunction

Just heard back from support.  So far, so good, they are reviewing the logs.  Hope to hear postive info soon.

I just have to ask, If you had flown this this route several other times with other drones, and knew the trees were 100-120 ft high, then why did you set your rth altitude at 98 ft?  I know it wasn't used, but that just seemed strange to me.

Yes you can see it in 0.4 sec that at one time the sensors see something.

I assume you are referring to return to home ATL.  To answer that question, I had not planned to use RTH for this intial flight.  That said, I have and I2 and Mavics (x4)  (and a few other of non DJI drones).  I take a lot of low ALT nature footage.  So during many of my initial flights or firmware updates,  I run a default route.  Given this was my 1st P4P, I wanted to see how it responded compared to the I2 and Mavic during flight.  That said, the P4P did initially respond as I had hoped, but unfortunately, it loss power and crashed some distance away from the tree line as indicated in an image I posted yesterday, and during that final run, I was well above the trees at least 20 feet or so.  I am getting increasingly concerned that DJI will assume like some of you have that I crashed into the trees.  To add to this increasing concern, I was filming and decided to take photos during the final run rather that video.  So at the surface, I don't have hard digital proof of the event, only a neighbor, my 13 year old son were eye witnesses.     Given the amount of equipment I've purchased from DJI ( OSMO+, OSMO, I2, Phantom, Mavic, X5, X7, and a number of accessories) without incident, I am hoping they can trust that I am being honest here.
For what's it's worth, this was my 1st hard landing with a DJI drone, guess it was bound to happen soon.  I am thankful however it occurred at homebase rather that over a populated area.

Sorry if you think I was assuming,  Didn't mean for it to sound like that. The flight log does show that all telemetry just stopped for some reason and I think it's a good case for review. There have been others lately where hardware failure turned out to be the reason and this could certainly be the case.  Good luck and I hope you get it straightened out to your satisfaction.

No worries.   And thanks!

Well the internal log in the drone may prove more usefull in solving this mystery.
Hopefully you get it all sorted out.
