P4P Motors S/D and fell from Sky...Really!

[Rotorhead]

First time posting ...Slow hover @ 150 +/- ft. Alt. slight breeze over sunny snow covered ground sliding to the right for the Money shot when it just literally fell from the sky. Battery @ 97% what I gathered from Airdata slight voltage deviation in cell 3? could I have found the perfect storm and Phantom thought it had landed and S/D motors as the breeze caused lift? could the ground detection be to sensitive or hampered by snow and the IMU detected failure to descend and disarmed the motors as in a normal landing maneuver? Took out R.side landing ant/skid broke L side landing ant/skid and lower shell, tore off camera. was able to power up and retrieve DJI Assistant Export DAT file. also downloaded DJI Flight record. I will send in for repairs but would like to keep it in my possession until the cause of crash is determined. I just really want to know what happened. This site has been a godsend since I started my UAS life and from reading previous Threads their are some real Phantom Guru's out there who can assist me

You need to post a link to your Airdata upload or upload the file to here and post a link back.

Can you post the DAT file too?

 

[sar104]

I don't see anything abnormal in the txt log data, which is quite common in cases of sudden power failure. The cell 3 deviation is not large enough to have caused the event. Need to see the DAT.

I am suspecting another battery dislodge. Have seen a few of those lately. A bit disconcerting since they have all been P4's.

 

[Rotorhead]

how do I post the link back?

We already have the txt file. Which link do you mean?

My thought too, but I was going to wait to see the motor voltage data.

That folder is showing as empty. Is it still uploading?

 

[Fly Dawg]

You uploaded an empty folder. Try it again.

Thank You for you patience... Learning how to navigate site...

That is the uploaded and converted .txt file. We need the .dat file, preferably from the aircraft itself, but you can start with the one from the device. Share as you did via dropbox.

I think I got it this time!

You did, but that file does not contain the DAT records from the flight - it was just a power up. You probably need to look for an earlier DAT.

the flight only lasts 53 seconds I will see what I can find. Thank You!

 

[Fly Dawg]

Yep, an earlier .dat.

No - that's the same file.
