Hello forum world!

I recived my Mavic Pro about a week ago as I was headed out the door to China for a business trip. I frantically unboxed it and made space in my backpack, I was excited to say the least! I landed, got to the hotel and finished the unboxing and setup (including firmware update). Yes, Mavic Pro it is truly amazing to travel with. The picture is great! The controller is better than my P4 (IMO). I got some gorgeous shots in Shanghai, Zhujiajioa, Suzhou, Tongli and other places. All was well.

Fast forward one week to today - While flying over the Bund in Shanghai I was performing a backwards shot over the water leaving the new Shanghai Tower and its surronding. Everything was going great and I was just getting ready to slow down and bring her back home. Then the video cut out... and the RC lost connection. I waited patiently then impatiently for 2 minutes (A small crowd had gathered to watch me fly). But no connection. So i took off.

I did the only thing that made sense which was to run and go find it, and here is where it gets weird for me. I switched to map mode and it showed my Mavic moving left and right in place about two miles down the road from me. I got to the location of where it should have been and there was no clear site line from where it had been coming from (between a gold building and one that said citi). I looked at the map closely and realized my starting point according to the map was a few thousand feet inside the city, not the harbor from where I took off from. I spent the next 3 hours trying to project my flight path from where I really took off to find where it really would have landed but nothing. I looked at my log and compared it to the video preview on my phone and the two didnt' quiet match up right. I searched and searched and searched but as the sun rose higher and the streets got more full, my heart sunk. After walking around for 7 miles I had to call it quits. My Mavic Pro had disappered.

Called DJI Support and found out they are only open M-F... Will call again on Monday.

Now that i'm 6 hours removed from the incident and about to board a plane regret and panic is setting in. My Mavic just flew away somewhere and either crashed or landed in some random place. I'm not mad, I'm not frustrated, I'm not straight up blaming DJI for anything (although it did just disapper), just sharing my adventure and hoping for anything good out of this situation.

Keep flying everyone!

Aha! So the DJI Go App was tweaking out. My healthydrone.com shows something else all together. So I either hit a building or it landed on the sidewalk and someone walked away with it.

Mine arrived in Xi'an a day after I left so couldn't bring it to Shanghai which was a real bummer, although I wasn't that comfortable about flying it in a major city like this. Going down to the bund tonight, if I find one lying around somewhere I'll be sure to let you know.

Did you attach any contact info on the drone? First thing I did when I got my Phantom. Taped a tiny piece of paper with my phone number. There are some honest people in the world.

And you ahould be mad, frustrated, and blaming DJI if the device did something it was not supposed to.

RTH should work in all modes. It should just stop current flight mode and switch to RTH.

Hey F.C. Drone City.

I actually never switched modes at all. I was always on P mode (or so I assume...). I pressed (and slid the bar in the app) for RTH once I lost signal, thinking it would reconnect and come home.

I've seen guys on my team crash plenty of times before and the video would still record for a few seconds. This just completely cut out which lends me to think it didn't crash maybe!? Lost signal and just landed somewhere.

That is strange. You were out in the open, over open water, I'm not sure how you could have lost GPS signal at that point and there clearly wasn't anything you could have hit unless it was a bird strike. And I don't think a bird strike would be evidenced by the video completely blanking out from a stable shot.

Hey Zatx,

Thats what exactly prompted me to write in the forum; seeing if I missed something. I'm usually a very conservative pilot and don't take unnecessary risk (for the sake of people around, not necessarily my drone).

Hi !
Sorry for your lost Mavic, its a nightmare so shortly after you received it :-(

Could in not just be a simple thing:

As you were flying backward, couldn't you have simply hit a bird (well, or another drone however unlikely that is) ?
Wouldnt that explain it all ?

When i fly my larger crafts i never had a problem, probably they are scared by their size & noise but with the small Bebop 2 that i used for travelling / backpacking it got often attacked by birds, one time brought down by a falcon.

Could this be the secret ?

Greetings,

Nils

It would depend if you were flying forward yes it would be right turn, however if you turned sideways to the left and aircraft was facing up river then it would be a left turn.

It looks like you were flying backwards straight into a big building. The route stops at that building. Fairly foolish flight really... interference warnings, out of line of sight, busy city, buildings too high for RTH etc..

Just had dinner in front of those buildings, went to have a look but if it had fallen to the ground it would have been found long ago and if it didn't there was plenty of places it could have fallen that it won't be found for a long time.

Yeah my guess is you hit something while flying backward at top speed causing the signal to cut and the drone destroyed. Hopefully it didn't hurt anything or anybody else.

My first concern was that I hit a building too or worse somebody could be injured. I passed the building shown in the map a few times and asked the security guard if a drone flew/landed/crashed around there and he said no. Same with the reception inside the building.

Sorry for your loss.  But losing eye contact, flying backwards in a high interference area with skyscrapers sounds like a bad idea.
