P4 Crashed uncontrollable spin

[DocDiggler]

Hm maybe some other quadcopters but not the p4 its to heavy
I know a hexacopter can but even they will struggle

I doubt weight is the issue, Seemingly it's the absence of the necessary code in the flight controller that is the issue. Check this out if you are interested Watch This Intelligent Quadcopter Recover After Losing A Prop In Flight

My P3 Standard did almost the same identical thing. It was hovering and then started a violent spin, tilted. I could not ever gain control. I was flying a couple nights ago in my cul-de-sac. It came down very fast and basically exploded on the asphalt. It hit so hard the battery cracked. I tried to communicate with DJI to see what they thought (via chat) and they just wanted me to "send it in so they could look at it." This was absolutely ridiculous as the whole thing is ruined, pieces all over the place. The gimble broke off, the propellers all broke. One of the shafts was broken and bent and the whole shell was cracked. It was a mess and I was picking up pieces all over. I had even given him the link to the log which I will provide here. It was not under warranty, so they didnt seem to care. I've seen videos on the internet that show the same exact occurrence. DJI knows **** well what happened and didnt want to tell me. The only thing I can see is magnetic interference, but it often says that.

HERE IS THE LOG

Update.....

Drone has been repaired by DJI for free.

Interestingly it's also my original drone that came back i.e same serial no.

They have repaired motors, gimbal & camera.

And the icing on the cake, they sent it back with a new P4+ battery. I only sent the bird and controller back as requested.

So well done DJI I am very happy.

Now if only they can sort out the android DJI go 4 app!

I had this happen twice back to back on my Phantom 4 and DJI replaced them both with 100% coupon.
Seems like magnetic Interference kicks you into atti mode and Yaw errors take over , the bird spins and flys away.

I know that death spin anywhere . lol

"100% Coupon" -- is that the warranty?
By the way, thanks for the reply. My conversation with the DJI associate was not great (through chat) and it seemed like he was just blowing me off by asking to send it in when he could easily look at the logs and see what happened.

Yes you get 100% coupon in an email for the replacement of your drone.
With that said we had 15 emails back and fourth each email taking a full day for them to respond.
I was also on the phone with the agent that was assigned to me.

If you have the drone you do have to send it in, in my case it was two fly aways.

Your flight data shows that at 1:22.2 your drone was almost hovering, only moving forward very slowly and things came unstuck.
It rolled quickly to one side and leaned back and started rotating anti-clockwise.
A fraction of a second later it was losing height.
It fell tumbling and spinning to the ground.
It's pretty clear from the data that the cause of the incident was the loss of either a motor or a propeller.

If DJI looked at your flight data, they would see what I've told you above.
Since it was an old drone, long out of warrantythey aren't going to do that without payment.
But they would need to look at the internal data recorder to find out what caused the incident.
Without that, DJI have no idea whether there was a fault in one of the ESCs or a motor or if the nylon thread inside a prop broke or something else.

Where in the Flight Data did it show the Magnetic interference , sorry that was for the guy with the Phantom 3 , my mistake.

 

[Meta4]

Where in the Flight Data did it show the Magnetic interference he referenced ?

On the very last line.
But it's irrelevant as it was 6 seconds after the problem happened and the drone had already fallen 280 feet.

In regard to a propeller -- I thought that as well. All the propellers were on it upon retrieval (broken, but on it).
Is it possible that the propeller came loose? That wouldnt make sense though b/c it was flying fine.

Thanks for your response(s) -- everyone.

Is it possible that the propeller came loose?

It's not likely. Loose props usually fly off.

I just had the same thing happen with mine but unfortunately it landed on the water and was not retrievable. Looking at the flight data on Airdata it shows just a seconds or 2 before it had 2 error messages of Not enough force/ESC error. Explained this to the gentleman on chat and was given a phone number then an email address for them to tell me that the drone was over a year old and they would be happy to sell me another. It seems as though this is a known issue from speaking with them and there solution is to sell another drone. Just my opinion though.

Also curious on how much time on the Phantoms that have done this. Mine was about 32 hours.
