Drone comitted suicide, warranty?

[xxx]

Hi all and help please,
I figured I would ask here before contacting dji regarding warranty due to a malfunction.

I was flying through a forest, narrow sensing assign to c2 button. p4p stopped due to obstacle, narrow sensing wouldn't react, height 5 ft, distance about 200ft. Couldn't get the p4p to move. Battery dropped below 30%. Pressed and released c2 button several times. Nothing. So I turned off the obstacle avoidance in the go app menu. Then I could move the drone, flew past the obstacle and turned it around to fly home. That's when the auto RTH countdown started, I tried to land within 7 seconds. Drone wouldn't react. Then the p4p decided to commit suicide: it took off in the opposite direction at high speed and crashed into a tree.

If the p4p doesn't react, is it my fault? I uploaded the flight record.txt here:
DJI Flight Log Viewer - PhantomHelp.com

I couldn't figure out where to upload the .dat file so I attached it to this post.

Thanks in advance for any help!

ps. "you shouldn't fly in a forest" comments will be no help. Have done so many times before and got some of my best footage that way.

It did not take off in the opposite of its own accord - it did so because you applied full reverse elevator at 755.7 seconds, 1.6 seconds after it switched to RTH. It appears to me as if you panicked, because you pulled back on both sticks when you tried to make it land. That crash was pilot error.

Thank you sar104! How did you decypher the dat file?

I didn't need the DAT file - those data are all in the txt log. But if I had needed the DAT file then I would have run it through DatCon to decrypt and process it.

• Litchi tablet app
• Autologic tablet app
• FPV tablet app

DatCon
DatCon reads the .DAT from a Phantom 3, Phantom 4, Phantom 4 Pro, Inspire 1, and Mavic Pro and produces output files that can then be used by CsvView, Excel, Dashware, and Google Earth.
