Grey Mavic Down

OK
So I got home and decided to see what I could rescue in footage from the drone.
Most had already been copied but this was the end result.
I'm really pleased with the quality so I haven't given up on drones yet - I will be getting another.
To me, this kind of thing is all about having memories of the wonderful places we have been.

Sorry about the music - I wanted to use a royalty free track so that it plays anywhere.
 
Lovely video.
I nearly repeated a similar incident to yours, but I was lucky and got away with it. Luck plays a part.
Sorry about the thread drift above.
Not as bad as your loss but I broke the tablet I have been using to fly my drone :sorrow:. I had found a stable early version of the DJI Go app and stable firmware for the Remote Controller, Aircraft, and Batteries. I had removed the SIM card and turned WiFi off - which meant I could fly anywhere at a moment's notice with never any delay while the system demanded an update. Now I've got to start again, not as expensive as your situation but very frustrating.
 
A scary, weird thing.
I got back home a couple of weeks ago and looked at my electronic logs/tracks.
I always keep these logs as a history of our cruises.

When I looked at them, I found that there was a MOB (Man Over Board) recorded.
We have never set an MOB.
Now - guess where the MOB was - at the exact spot where the Mavic went into the sea!!!

This is a screen dump from OpenCPN's track.

Scary - or did something actually record it - the boat and the Mavic would have been on the internet.
I'm sure there wasn't an electronic interaction - but ......................
 
Nearly lost mine at the weekend!

Leading the Commodores sail past procession past bray, launched from the boat with a view to filming the whole episode, and the iPad screen went blank (No camera) and the drone wouldn't respond!!

After pulling out of the fleet, I managed to turn round and grab it, at which point it went mentally on full throttle (Not a nice experience let me tell you!) but I managed to hang on and turn the thing off using my other hand and my mouth on the remote.

Turns out it required an update between my morning test run and the sail past a few hours later....DOH!

I left it downstairs sulking for the day before bothering to even look at it :disgust:

But is the drone itself running a RTOS? I know that at least some of the smaller ones are running a fairly standard Linux, probably on ARM.

Yes it is, but the controller (the phone) isn't, so whatever was the last instruction will continue until continue until the phone tells it to stop, or the current instruction will halt until told to proceed by the phone. All in all, not an ideal situation.

I suspect the reason it went ballistic when you grabbed it was because it was trying to get back to its geostationary point. You were moving in the boat and in so doing pulling it away from where it thought it needed to be.

It’s the sensors underneath that cause the pull away when hand catching - you can’t disable them by going into sport mode, so if things are calm the best way to hand catch is have your hand ready, pull down the left stick to land and the MP will raise up and then lower if you persist with the left joystick. But not easy when you are in panic mode!!

I have just joined the club, losing my Mavic in early September through sheer stupidity. We were in the charming and very small port of Sant'Angelo in Ischia, and the quayside of which where we were moored has as its backdrop a large high and vertiginous hill. I had just completed filming some great footage, and I was flying the drone backwards to position it to get a downward shot of Artemisia against the village when, without actually watching where I was going, I crashed it into the top of the cliff face. I only realised something was wrong when I saw on my phone's screen the drone's camera filming it tumble downwards before coming to rest upside down in undergrowth half way up the cliff face.

I was inconsolable for days as, apart from the cost, the SD card had videos and photos from previous flights that I had yet to download onto my laptop and which I knew were irreplaceable memories. You can therefore imagine my excitement when at the end of our holiday, on the flight home from Naples, I discovered that the videos (but not the photos) were actually safely stored on the Samsung S6 that I had dedicated to use with the Mavic controller.

When I have the time I will do a post of of our fabulous summer's cruising with the incredible photos I have taken, and edit and upload to youtube some of the stunning videos.

That is the exact reason I have been flying mine with all external connectivity disabled (ie: SIM card out and WiFi switched off) so the wretched thing couldn't suddenly demand updates at inconvenient moments. The number of updates that DJI distribute is beyond ridiculous. Half the time the updates are to fix bugs in the previous update that hasn't been tested thoroughly before release, if the DJI and Phantom Fliers forums are to be believed.

But none of us has addressed Hurricane's question: did the Mavic send an MOB distress signal? I understand the MOB is on the OpenCPN record of the voyage but is there any information about how the MOB was transmitted? Was it on a VHF channel? A WiFi signal? Lightbridge? Is there anything in the data packet to prove that it was the Mavic that sent the MOB? Was OpenCPN the only software that detected the MOB? - presumably the answer to that is Yes because the plotter would have shown it if it had come through the "usual channels" - I think. Is that right? I agree it is a very weird event and one that bears scrutiny. We don't want the Coastguard to start despatching lifeboats and helicopters to recover drones that have gone into the briny and sent out an MOB. That would make us very unpopular.

That’s awful Mark, but at least you have the video files in the DJI app. I think that they will only be 1080p but thats still fine and better than a total loss...

Look forward to reading/seeing your cruising story - just a note to all, don’t forget that DJI offer a very good care package for £100. You get replace repair service - we used it twice thus far and DJI’s response has been fantastic.

We have had to to send the Drones back on each occasion, not sure how they would react to an MIA drone but I have read that they will replace ‘fly aways’.

Worth registering your drone for that cost imho...

(Can’t do it after the fact tho’), not that any on here would even dream of trying to do that ;)
 
@No regrets, yes as others have said it is perfectly normal for it to go full throttle if you grab it by hand and try to move it from its attempted geostationary position

@mWeiss, sorry to hear of your loss. It becomes normal - I'm on my 4th dji phantom, having this year lost a Phantom4. You can't move in my place for spare control units :D. You gotta take risks with these things to get nice shots, so a few losses are to be expected. And use a fresh SD card for each flight-as you now know! It's good to hear the Samsung saved the videos, but they will be at 720 resolution only (which isn't bad of course). Looking forward to seeing your footage after you have edited it. I'll put a Corsica 2017 movie up shortly

Fortunately, a few months on the DJi forum reading about other peoples 'exciting times' and I expected it, but it has quite a pull to it! Not to mention the noise....and those thrashing blades...and the wife in the background....Dogs trying to jump up and attack it....Jeez! :p
