Jason ,

Yes you are correct

Ah. I thought you were wondering if we had to kill the motors with a CSC if Landing Protection is off, not just hold the stick down.

Wellsi Posted at 2017-4-7 06:36
Lol....!   
Actually, I think you get around $1 per thousand views, so I'd need a million views to make that money....  
Given the specialist nature of this video, I don't see that happening...  Maybe I'll be able to buy a spare set of propellers

Hell, I even watched it a second time, just for the sake of getting you the money

Did i already mention this is by far the best video a watched in a long time.
Informative

My advice, watch this clip.

To clarify, I don't just rely on 30% battery life as the only factor in returning to my original take off point. It is one of many factors I consider that I did not list.

And one factor i use the OP mentioned is wind direction and speed, flying generally into the wind outbound and flying with the wind inbound as much as possible.

4wesome ,

Even with all the many Factors that we all consider --- Chit Can Still Happen
One does not know how they will react when put in Wellsi/Ian's situation
Unless they have been there B4 --- Sure you can picture it and say I would have done this or that
But it wind up being a different story when Fear an Panic set in .  
A lot of people can not relate or except there Faults that they crashed or Lost There Mavic
Ian is an Exceptional RC Pilot , He was aware of his surroundings , he used his human sensors of wind,
estimation of battery life left, visual for distance and to find a safe landing spot and Most of All he remained in Control of his Craft and realized at what went wrong, these may seem like little things But trust me they are not when Fear and Panic set in !
I do not wish this situation on anybody and If people think I'm full of Chit with my post, all I have to say to them is --- One Day You Will Understand, One Day
   

Good analysis / LPT for flying a mavic. Sorry to hear about his drone's loss. I asked my wife for a funeral for my lost drone (which luckly was a cheap drone).

So sorry for your loss first of all.
Thanks for doing this, at one point you say that people can laugh about this. I don't think it's anything to laugh about here. You just show how complex it is and so many things to keep in mind flying this things. I personally feel thankfull for your efforts and vice worlds.

Can I ask a question, you said that you should have made an auto landing instead of a manual one, where you sure that it had landed or not? Ie did you have a video feed at that point or something else that made you sure of that you had landed?
If it was landed I think one thing that we could ask DJI to implement is that if the battery percentage is lower than X % it should NOT be possible to take off again. That way you will still be able to manouver it back home on a low percentage of power but not take of which is something completely different. It's hard do see in the video but I think you where somewhere around 10% which is the "landing" if you have set that parameters in RTH  to "Normal".  I think this feature would save a lot of guys in the repair que aswell cause it seems to be crowded there for many reasons but.....

Anyways, thank you again

Happy flying with your new machine.

Ok, I see -- thanks for the clarification. Even if the motors are still running it knows it has landed and (in my opinion) shouldn't take off and try to return to home just because it lost the connection to the controller. As Jason said, that seems like a bad design decision.

When you land the AC it just lands in order to shut down motors hold for 3 seconds,

The IMU reads that the aircraft is unable to move any further, and after three seconds it determines that is has officially landed and can shut off the motors safely.

I don't think the motors were shut off so hence when signal lost RTH.
There was another case similar here when someone landed aircraft he was 30 feet away, but didn't shut down properly , turned off remote control, and aircraft just took off.

So turn remote control on first off last.

This is an excellent video and it's refreshing to see someone not only acknowledge the loss of a drone was their fault but then to analyze the causes and do a great job of explaining it to others is exceptional .

I personally would not have thought it would have taken off again after landing and DJI should look into this carefully as it could easily become a liability if someone were to walk up on it and it spool up and take off into their face !  Imagine a curious child seeing it land with no one around and it hurting them . In my mind this actually should be a good case for DJI to admit it wasn't all your fault since you did everything to get it down safely in an area where it could be retrieved and their programming caused the subsequent loss of the aircraft .

Hall,

If you have landing protection enabled , once you fully land ( Mavic on the Ground ) motors shut down automatically

I understand that, but OP didn't so only option to turn of motors left stick down and hold 3 sec,

But I read here all the time here people advising others to turn it off, not to sure why.

I thought you did not know about that mode --- I should have known better that you already knew

{:4_177:}  

I feel your pain but thanks for sharing and your points are noted.

Ian if you paid with a credit card it may be covered if its within 3 month

lord. I just got my mavic a lil while ago and have had my issues already ( some of you know what im talking about ) but the more i read on these forums, the more i never want to put my $1000 drone in the air hahaha

As many have already said this video is one of the most informative videos I have ever watched for a Drone in recent months.  Thank you Ian for giving me this insight that will hopefully make me a better pilot.  Respect from a fellow Brit.

I don't know, what am I missing here? Could you not seen the red arrow to see if you were brining it towards you or in which direction it was travelling? Without having to assume that it was going away from you?

Thanks for sharing that with us.  Any experience good or bad is valuable to the next guy, what to do and not to do.

Thanks for putting this learning video together. I find I get over confident sometimes and that could get me in trouble so watching videos like this is a really good reminder to never push the limits. I've pushed the limits before and then once I was 'home' thought to myself I was pretty silly... and won't do it again.

From a learning perspective, do you remember what you were concentrating on at the point it was passing by you (I think it was at approximately 450m)? I know it's easy to say in hindsight you could have looked at the map/radar view so you must have been concentrating on something specific that kept your concentration away from that.

Again, thanks for posting and sorry to see this happen

Sorry for your loss.  Also, great video sharing your insights.

One thing I didn't hear you mention was anything about the onscreen map.  The same map you show in this video detailing the flight path.  I've been flying an Inspire 1 for about a year and a half and I'm now very use to using that map.  Between that and the little radar screen, I can see where it is, where I am, which way the craft is facing and which way the camera is facing.  If I'm ever in doubt (personally I don't like RTH) I aim the craft on the green line and fly home (of course avoiding obstacles).

One thing I've noticed on my Mavic is that I don't always have the onscreen map.  Perhaps it's because I switch between a phone and tablet?  Anyway, I cringed when I saw you were not flying a B-line back to you and you ended up passing yourself.  An additional piece of advice I'd pass along to you and others is utilize ALL resources at your disposal. Use the onscreen map.  Visually look for the craft in the sky (or down the cliff).  Listen for the rotors.  Make sure that everything you expect to see and hear agree with each other.

Hello, first sorry for your lost! And thanks for your video and sharing experience!!

I dont understand one thing!!! If you shutdown your controller and "lost connection" with Mavic, How the flight log locate mavic after you turned off control?

Thanks!

Yeah if way out there and you have to land, auto land is pretty much the best option you have. At least you have some good shots of that memorial!

I thought the Mavic would force land itself if the battery was too low on RTH.  So, even on RTH it just goes until it falls out of the sky?  On several occasions I have ntentionally pushed the battery limit while flying nearby and at some point the aircraft gave me 10 seconds before it started home.  Even if it was on an auto return path, one would think that it would land itself before it fell out of the sky.  I mean, what is the need for all of the automatic tech on this thing and not have this particlular action as part of the backup?

Ian - THANK YOU!  
As someone new to this sport, I'm very grateful that you took the time to dissect and disseminate what happened.  I'm sorry for your loss, but to see someone suffer the loss but then share the lessons learned is invaluable for us to learn from.  Again, Thank You and Good flying!

I am so sorry for your loss!! Nobody should be laughing at this at all!!  Thank you for taking the time to present your information so that others will not follow in your unfortunate footsteps.

Let me say that you are a stand up fellow and putting the blame on your mistakes during the flight. I have done some of these things as well with my Inspire 1 but not to the extent of yours.

I sincerely hope that DJI see's this and helps you with a discounted replacement

All the best to you sir
Rich

Tommy,
This is to help you with your no map problem
It's obvious you are flying without an Internet connection ( Which is a good thing - Less Interference )
what you need to do to get the map's to show is when you are connected to the interweb at home or anywhere you find an interweb access point--Open the GO4 app , click on the radar indicator to open
up the map view or satellite view , zoom in all the way down on the area you are going to be Flying in
then drag the map all around the flight path you are going to be Flying ( I use about a 2000ft radius)
by doing this the DJI GO4 app is putting the Map/satellite views + info into your device's cache -- then
shut it down go to the Flying area that you just Cached --- power up your RC, Phone or Tablet in Airplane
Mode then the Mavic --- Open up your Map or Satellite screen BooM now you have the Map and satellite
view that you Cached earlier visible ( Do not clear cache or Data from your device it will cause you to loose
the maps)
Now I'm going to give you a HeadsUp -- when you are Viewing the map when it's reduced in the lower
left corner of the screen, I believe it's the satellite map setting your going to notice a compass symbol in the upper right part of the screen -- if you click on it --- it keeps the map locked to North no matter what your related position is to the Mavic ---- Click on the compass symbol again and now the map will move with you in relation to the Mavic <-------- when set to this, it is easy to become Directionally Disoriented
if your LOS is blocked or you loose site of your Mavic while flying in FPV .
Sorry for the long winded post I hope
Please if my method or directions are wrong please correct me !!
Happy Flying

That's a very fair point; trouble is, the little map display is now only an inch or so wide on your phone. The You Tube video has the replay blown up large and it's crystal clear what's happening the moment I start flying back.  That wasn't the case on the day; with the setting sun behind me and me focusing on the distance figure not coming down, I didn't notice the arrow was almost pointing towards me but not quite......

Yes, I thought that. The Mavic was 120m below me; I thought I'd held it down for 3 seconds to shut off but was already walking away from the cliff edge back to the car (running actually); so, the moment I stepped away from the edge, it lost signal contact and I'm guessing never shut off and started its RTH ascent.  It took around 3 mins to jog back to the car, by which time the Mavic would have achieved it's return to home altitude, some 40 metres above the cliff height, but still 900 metres away, so it could have regained it's signal contact albeit it briefly. In either case, I'm running, jumping into car and at some point turned off the remote, but that's the only scenario I can see on how it regained contact and updated its location.
On the video around 8:10 you see the altitude jump from around -112m to +40m and the flight time jump up from 17 mins to 19 mins; that's all the data there was.....  How many times have a replayed this flight on screen and in my head...?

alirz5,

         I don't mean to be rude , by posting and saying " I don't know, what am I missing here? "
Makes you sound like this Can Not Happen To You , have you read all the posts in this tread ?
Read Post #44 -- have you seen and listened to his Video? Obviously you need to Watch and read
again. Obviously you never been in a EM situation with your Mavic --- Obviously you never read
all the Crashed my Mavic posts on this Form, they all  blame DJI for it.
In my opinion 99.9% of the time there Crash is due to "Pilot Error" I'm going to put it in Laymen's
terms -- IT WAS THERE FAULT!!!!
Wellsi experienced all of us fear the most " Loosing The Mavic and Crashing "
Your lack of empathy for Wellsi's situation after he did all that he could possibly do , which is way more
than any other loss or crashed story on this site!!! -- Long story short , Wellsi made one small mistake
that cost him his Mavic , He realized it , he explained it , he made a video of it showing and explaining
his flight path , Then admitting to all on this Form and YouTube it was his Mistake !!!
After he had done all this you come along and post the stupidest opening line on a two page thread!!!
" I don't know, what am I missing here " WTF HELLO WAKE UP
Then you question him about a small red arrow ( we all know what the red arrow is ) as if it would have been the only answer to get him out of trouble with all that was going on in his head ?
I find your small post to be Insulting , lacking of empathy and as if this situation will never happen to you
I also see Wellsi answered you insulting Question --- I hope it was to your satisfaction      
Alirz5 I'm finished now so Have A Nice Day

Stop freakin out. You seem to be angry at me whereas the OP seems to be ok. I'm not blaming anyone. I was just wondering, if there was something wrong that the OP couldnt use the map and bring the Mavic towards him. I've lost connection to my P3 and mavic several times, in fact on my very first flight with the Mavic, i was 2KM out over open ocean when the app died and would not reconnect.
I simply followed the display on the RC, and used the distance meter to bring it back to me...Didnt even need to use RTH.
I've been a DJI owner for years now, likely longer than you and probably have more experience than you. I very well know DJI's crooked policies and their lack of support when things go wrong etc...

I feel bad for the OP but while this could have been avoided by simply paying more attention to the radar map. But again everyone messes up at some point. I likely will, one day too.

He convinced himself that if he flew over the cliff line, there would be too much wind to overcome in sports mode. It was just pilot error, and then when he landed the motors didn't shut off. I've been in situations where the battery was low and had a ways to go, so know the situation he was in. I just keep calm and it all works out. The mavic is so nice far as knowing the time left, not much else to say but pilot error pre judging the wind the way he did. But he admits it was just a clusterf.

Unlike some people on here, as skunk points out, they fly into the futon and trees, complain it's not warranty.

Have you tried using your new Mavic to find her?

alirz5,

       I'm not freaking out , I'm not attacking you. The problem is that after all Wellsi did --- Explaining, Posting a Video, Realizing what went wrong and then admitting it was his fault in posts and answering all posts to him concerning when and where he made a small mistake that would have happened to any experienced RC pilot -- except you, according to you two line MindLess post and on the second page
of the thread no less, if you didn't notice Your question was already asked on page one --- either you don't
understand English or can't read which would be understandable to me.
Then your Kocky opening line of "I DONT KNOW, WHAT AM I MISSING HERE" that I already brought to your attention .
Then instead of thinking about the what and how you posted -- you reply to me with a story about how you almost lost your Mavic due to a DJI app crashing while your flying over the ocean , how much more experience you may have over me and then -- This is the best one --------------------------------------------
"You very well know DJI's crooked policies" <-----------Where this one came from I don't know ??????      
           First of all your story that you want to compare to what Factually happen to Wellsi is NOTHING
anybody with a simple mind could have done what you did and I'm going to explain why .
            OK Your flying over the ocean Fa La La De La La --- Oooo Chit The app crashed what do I do I cant see my Mavic , I'm not going to give it down direction it will go into the ocean , I'm not going to give it Up direction because it is already above the water B4 the app crashed I'm not going to go Right or Left
I don't need to engage RTH --- BECAUSE IT WAS ALREADY COMING BACK TO ME THE HOLE TIME SINCE THE APP CRASHED --- alirz5  I'm LMAO are you kidding me ???? Your comparison story is very weak a
NO BRAINER!!! Then you go into having more experience then me LMAO your kidding me again by judging Flight distance numbers ???? "Your a DJI owner for years"<---- Good for you , I have news for you -- your not the only one !!! Then you go into DJI's crooked policies ???????? <------ I never mentioned anything
about there policies and while we are on the subject "I have No Problem's With + Fully Understand Them"
you say they have a lack of support???? <----- I find all the DJI Moderators on this site to be extremely
Helpful and SWAMPED with Complaints due to manufacturer Defects , Demands for information on Repairs and Owners that want there Mavic back Yesterday -- We cant forget the Famous one's of all ---------------
"My Mavic did a Flyaway" "DJI app Crashed and caused my Mavic to Crash"
"RC Disconnect caused Mavic to Crash" "Crashed My Mavic DJI's Fault"
I'll bet that 98.9% of all of these are like always PILOT ERROR !!!!!
You claim to feel bad for the OP but at the same time you are Beating him down by saying and CLAIMING he could have avoided it by SIMPLY PAYING MORE ATTENTION TO THE RADAR MAP
I'll tell you alirz5 ---- Simple things for Simple Minds  --- you have No Clue about Wellsi experience !!!!
I can give you an example of what it's really like to Feel and go through what he did !!!
But I'm not going to --- I want you to experience it unprepared + unexpectedly   
I just wish I can be there when you Crap Your Pants

alirz5 Posted at 2017-4-8 20:09
Ok...sure? I'm definitely not going to read all that...

Alirz5, I got your point and to some the map view / radar arrow is blindingly obvious.   To be honest, all the points I make are pretty obvious once said and with hindsight.  Email and messaging can come across a little blunt sometimes but I took your point at face value;  Either way gents, don't fret about what's said; just focus on the (ever increasing) ways to avoid ending up in the same situation!

On the point of maps, a really good trick I only just found out is that you can easily toggle between large video / small map, and large map / small video.  Both are really useful views for different situations; Map View is clearly more useful when you're trying to head home or unsure exactly where your Mavic is, so dragging the map out to toggle views is a qiuick and useful thing to do....

And I'm hoping to hear back from the home insurance shortly

Cheers all
Ian

Hi Ian,

Just wanted to thank you for the detailed post-mortem, especially with the practical  "do's / don'ts" advice at the end.

I've never flown a drone before (I'm mainly a photographer, rather than a flight buff), and am seriously considering a Mavic.  The idea of sending a $1K investment flitting into the sky is a bit daunting, and I'd really like to get a feel for the practical difficulties and risks before taking the leap.  A video like yours is priceless for this sort of thing.

I can't even imagine how aggravating that must have been to lose your drone like that.  Taking the time and effort to put out a carefully detailed & well-explained post-mortem like this, just to help others, is incredibly thoughtful and public-spirited of you.  I'm very grateful, and I expect plenty of others are, too.

Thank you.

Thank you for the video.  Are you going to get another Mavic?

nay Posted at 2017-4-9 15:57
Thank you for the video.  Are you going to get another Mavic?

Already bought the replacement and got it!  Awaiting insurance decision on whether they will pay for it!

Better luck with the new one!

Thanks for taking the time to help others learn from your mistake. Question I'm new to mavic, Does DJi have the option of RTH auto if it reaches a percent of battery left and if so If im flying under tree and it triggers to RTH will it go up to altitude and crash to the umbrella type tree.  Another question on cliffs like that you should have had an updraft more than a head wind no?   Thank you

Nice video . I've been looking at those GPS locators so I could find mine after it got lost so could claim it on the DJI Refresh. I just don't like the fact that most of them are bundled with the SIM card and you get another montly payment on your credit card. I would prefer to choose the SIM I want to use. That's why I haven't purchased one. Those little things are sturdy and probably would last a crash if attached tightly enough to the Mavic. It would then send the real location and not the last on air in this kind of situation. After looking at this video I'm starting to reconsider buying one...
