DJI replaced my Spark last week, I have to say they were totally excellent, it took less than 2 weeks from leaving my house to receiving the replacement.

Second flight with the replacement last night and strangely, after about 9 minutes flight, it started auto landing with 32% battery left and no other warnings, it started a forced landing. I have the battery warning level set to 20%.

There's a disparity between IMU and VPS altitude, I was flying directly towards a setting sun at the time so I wonder if that was the cause although I still don't understand why it would start landing. I could still control the Spark and I wasn't far away so all ended well. It could have been quite different if the Spark was further away, over water, etc.

Here's the log file, it happened at 9:40.4: http://www.phantomhelp.com/LogViewer/8FF958NV3Q8Z4X7MPNWD/

Here's the video of when it happened, I turned the face away from the sun in case that stopped the landing but it didn't:



Any ideas?

Thanks.

I am sorry about this, Peterev, could you please export the flight data in the drone and upload it to Dropbox for this case and paste the link here? I'll help to transfer it to our engineer for a better analysis. Here's the exporting tutorial for your reference:

Thank you Thor but I refreshed the firmware which cured the issue, she is flying beautifully now!

Hey, thanks!

what did you use to edit it with?

what did you use to edit it with?

Photoshop CS6, photomerge. Have to say this one was a little strange as the bottom half of the image after merging was pretty distorted hence the major curve in the road at the bottom right.

Not had that before, normally the merged image is pretty straight enabling a ~6,000 x 4,300 image to be cropped.

You posted wrong link. But hey looks like your sorted, btw nice 180.
