During a flight yesterday, ascended from the ground up to about 40 ft, and then all of a sudden, the mavic did a flip in mid-air...  There was a little bit of wind, but nothing that the MP can't handle.  Not sure what happened...don't know if it was a software error or sensor issue... video clip on YouTube, would appreciate your opinions.  I sent it to DJI support, waiting for a response, but figured I would post something here to see if anybody else has seen this.

I think the gimbal did the flip if that's what you meant- a wonky calibration attempt of some sort. I think someone posted a similar issue a few weeks back.

No, my buddy saw the actual drone flip, not just the gimbal, and I actually caught a glimpse about mid flip.

I also just checked my logs, and I'm not seeing that particular flight recorded...so I have no idea.  I can see the log before and after, but not this one.

OK... Yes it flipped big time!

First mistake, you took off from a CONCRETE SLAB. Second mistake you took off next to 2 cars. Third mistake, your antennas were not in the correct position since you were flying straight up above you.

Most likely all of those factors messed the hell out of your MP and it did this AWESOME FLIP...Man that was cool dude!

From now, never fly off your concrete driveway or walkway. Do it off the street and away from cars!

What mobile device are you using? See if you can find the flight record files in your phone. For Android devices, connect the device to the computer, find the flight records stored in …\DJI\dji.pilot\FlightRecord\,  For iOS devices, connect the device to the computer, launch the iTunes, find the flight records in the DJI GO 4 app. Please provide me with the flight record, I'd like to look into it. Besides, since you've contacted the Support, do you have a ticket number or case number?

Bro, most concrete does not have reinforcement...especially sidewalks and driveways. This was the gimbal and not the drone most likely, put your .DAT file from this flight on Dropbox and we will see.

It had nothing to do with the concrete, antennas or cars, something just glitched.

Regards Mike

I have one of those 36$ drones the size of a playing card and it has a button that does this flip.

I kinda wish I could make my mavic do it.

Obviously two of your motors cut out for a second.

Lucky for you they cut back on!

You unlocked the secret acro mode, apparently. This was almost certainly not a gimbal "flip." I've had mine do it before, but this is clearly the entire rig going end over. I'm interested to see what the results of this are.

wow....i tot only the other made can flips...didnt know MP can do that....really safety reason ..dji have to get a fully check on this issue...

Definitely a flip - camera view upside down if you look at the footage frame by frame. "Gimbal gone wild" looks different, and besides when gimbal glitch happens, it cuts off recording. Here recording went on.

Concrete slab is the most probable culprit.

I too have (a bit cheaper) hexacopter with a "flip" mode button. Press it then indicate with the right stick which direction it should flip. The maneuver loses quite a lot of altitude.

It seems you were able to unlock the super sport mode

If you can tell us what they say about it, that was scary...

lol

What happens when your Mavic takes off (same speed) from the identical spot, in identical conditions (also the same phone) and identical flying mode?
Will it do this flip again?
Did the motors stop or perhaps only one or two in a flash? (you were close enough to hear a malfunction)

I have had a Mavic 'glitch' this way once.  Interestingly, like you, there were no logfiles afterwards... this might be indicative of a power brownout/failure mid flight?  EM interference perhaps?

The amazing thing with that flip is it recovered!
But, I'd be checking the ESC for a glitch for sure, must have killed 2 motors for a second, eh?

Yeah that was definitely a flip

Maybe you bought a Mavic clone instead of a real one. The clone does the flip trick. Good thing it recovered. Scary.

So the secret code to unlock the flip is up, up, down, down, A, B, up....jk

I flew in the area for a bit, and this was the only erratic behavior it displayed... But yeah, definitely had to change my drawers afterwards...  DJI responded with the following:

Hi Cody,

Thank you for reaching out DJI Technical Support.
We'll be more than happy to help you out with your concern.

We apologize for the inconvenience that you are experiencing with your DJI Mavic Pro. Upon reviewing the video that you have send, we have noticed that you are trying to fly your unit in a urban area. We do advise to fly your aircraft with caution.

There are many signal interference within your areas especially the Wi-Fi Connection. Some other signal interference that might affect your flight efficiency are radio transmission towers, power lines, base stations, electromagnetic interference devices, and large deposits of magnetic metal.

If ever you have any concerns or questions, please feel free to contact us again.
Thank you and have a nice day!
Best Regards,

Are you happy with what DJI support said?

This expensive  drone easily get "Interference" and my cheap quad copter doesn't.
They are making excuse to avoid any responsibility for any glitch of system.

Yah thats a flip I knew mavic could flip Just didn't know how it was done ...
.I would be very cautious with that bird for a while incase it goes side ways and you can't control it
I had my mavic fall from 30ft into soft grass and still can hear that sound to this day it hit the ground and puked out the gimble  assbly $350 later... My bird is rock solid....C

there are scary videos of this out there but more cause people are  jailbreaking the Mavic to do 'aerial-acrobatics' which will void your warranty and can be unpredictable and dangerous...

To be fair, in all the manuals it does say that flying in urban area's can cause silly things to happen - Interference and stuff. Never seen this though and glad that it righted itself instead of being a broken mess. I take it the craft is stable in flight the rest of the time and functions as it should..??

First, how does a concrete slab launch have anything to do with that? I am new to the drone, and I have taken off multiple times from a concrete slab (and near cars as well) and never had any issue like this. I am not being incredulous, I'd like to know if it DOES affect the drone like this, I don't want it to happen to mine.
Secondly, I see something right at :11 that appears in the camera view...almost looks like a black piece of fabric or something. It's not the prop, since the camera is pointing downwards as far as I can tell. Was something broken and hanging down? It appears for a split second...seems like something got either tangled or something broke and is hanging under the craft..

They are thinking the rebar in the concrete may interfere with the signals. Sometimes it may be cheaper wire mesh, much thinner but still, a bunch of metal spread out inside the slab.

I disagree with DJI's explanation.

When a drone flip it is something to do with the firmware or the hardware itself, and I believe the former is the culprit.

I would be silly for DJI to blame on the interference, it only makes its product appeared to be a cheap toy.

I've been trying to flip mine since  I got it.... tell me the secret!!!

Please I can haz flip mode?

It is true about concrete, it can have metal reinforcing it. I simple test is to pick a landing spot, and then look at the magnetic sensor data in the GO app. I would recommend doing that check any time you try a new takeoff point.

When the compasses get bad data things can go very wrong. I myself flew too close to some metal and the Mavic went crazy for half a minute and I was very lucky because it almost crashed at very high speed and no buttons or any actions could control it until it calmed down. Somebody could have gotten hurt! Now I changed my Sport switch to ATTI mode instead for just such an emergency.

Unless the video was edited, that was a forward flip. At no time did the camera show the body of the drone which is normally behind the camera. You can see the street below slide out of view at the top of the frame and slide back into view coming from the bottom of the frame

Wha??  How did you change your Sport switch to ATTI mode switch?  (Or was this a cruel joke?)  I guarantee there are thousands of Mavic owners who would kill to know the secret.  OK, maybe not 'kill', maybe just remove limbs from someone one at a time.

While ATTI mode is handy in an emergency, it is also something that can be dangerous in the wrong hands. We can assume this is why DJI has not made the option easily accessible. We can respect DJI in this regard.

No, 'we' do not have to.  Maybe you can.  I think it's disgusting that they removed this ability from the pilot in the Mavic series.  

Reminds me of Airbus, which was basically designed for the lowest common denominator from the get-go.  And no, I'm not just voicing an opinion here.  The whole point of Airbus' philosophy is to be able to get low-hours pilots flying you around.  The aircraft knows better than the pilot.  Because in most Airbus-operator cases, it really does.

Interesting flip.

And I thought only SYMA copters flipped.

Well given "human factors" cause the majority of incidents then its not a bad policy.  Its also a policy boeing have belatedly adopted especially with the binliner.

Road accidents are the same.  The squishy bag of skin and liquid in control is usually the cause of the accident.  The less control you give it the less accidents happen.

Lowest common denominator bash about airbus is (i) deluded and (ii) factually incorrect.  Im assuming the poster is american.

Guilty as charged.  I would congratulate you on your perceptive abilities or detective work, but the "United States" below my name kinda takes all the sport out of it.

As for the ATTI switch, I've located the answer.  There are even youtube videos with circles and arrows explaining how to do it.  When I first searched for the answer (textual web pages only), it wasn't immediately easy to locate, mainly because all you get are hundreds of pages of gripes that there is no ATTI mode.  Thanks sigkill.

Was your battery fully charged? Lol, seriously that was pretty cool..
