Hi,

Your airdata is private, need the flightlog to analyze.

If you like post a cloud-link to your flightlog on here
or use this link > https://www.phantomhelp.com/LogViewer/Upload/  
and post the uploaded link here



cheers

For anyone to tell more they would need to see the actual data.
You'll have to tick the Share box on Airdata so that the data is available, and post a new link.

Hi mitchy,

Had a look at your data, see my charts of your data.At 2m44s in flight your AIR2S showed high pitch/roll values.
Shortly after this message "motor blocked"
Drone spinning down.

In this log no data for motor RPM, if you like post the link tou your DAT file ( FLY022.DAT ), also on your mob device)

cheers

Hi mitchy,..........."f you like post the link tou your DAT file ( FLY022.DAT ), also on your mob device)"

Is the Air 2S DAT readable? If so, has it always been readable? If it has NOT always been readable, was the change brought about by an App update, if so which one? Thanks

Hi, thank you for reaching out. We're sorry for the unpleasant experience. In this kind of situation, I'm afraid that you may consider sending the unit in for a proper diagnosis. You can contact our support team to start up a ticket at https://www.dji.com/support. Also, the warranty can be applied depending on the outcome of the damage assessment including the warranty period of your unit. Thank you for your understanding and support.

not sure    AIR2 is readable...so i thought AIR2S too

Do you guys think it is a faulty unit considering it was only 2 days old

Maybe .. but it's hard to tell without the data to show exactly what happened in the incident.
Start up a case with DJI's online support people and hand it over to them to investigate.
They can read the data that the drone records and stores in the drone.

I think you had a problem with a prop or motor or perhaps a bird strike causing those, the logs report an impact but that could be a blade breaking and hitting the drone. I think what JJB is looking for in the DAT is motor data, which might gives clues as to what went wrong e.g. speeds, current drawn, voltages etc. If you can post the DAT we can maybe see if it is readable. The DAT is in a folder with a a name that starts MCDat......  you can post the file directly to here I think.
Did you recover the drone? If so were the props intact? Do the motors turn freely? Any feathers or blood on the drone?
If you recovered the drone is it smashed? if a prop was missing check inside the motor for any broken of prop mounting lugs, I pranged a M2P/Z in the house (my fault) and it broke a mounting lug off the prop's base, have a look at an intact prop to see what I mean and for comparison.
If an entire prop was missing and there are no bits inside the motor then I would begin to wonder if the prop was properly mounted.
If the DAT is encrypted then you might need to open a case to get them to look at the DAT, if a prop broke or a motor seized then it should be a warranty matter but I don't think we have the necessary information to determine that yet.

I can't find a DAT File for that one any tips?

Do you sync your flight logs with DJI? If so it maybe that the DAT was deleted during the sync.
Did you find the MCDatFlightRecord folder, if so was it empty?
What controller did you use?

Hi,

...the logs report an impact....

Not sure if the original log shows that kind of information.
Recently AirData shows general messages about impacts in pitch and/or roll direction....
I think they add by themselves, checking the sudden pitch and roll angles, speed ect.
Impact messages are not written in PH or AirData CSV files.

"Problem" with the decrypers is that we do not know if they share all information from the log into their CSV file.
Uhm i know  they don`t show all decrypted data into their CSV, just check headers in AirData CSV and the info on the site of a flight.....

cheers
