Greetings to All,

I'm having a problem with controlling my DJI Spark Drone. I have been experiencing difficulty controlling my Spark for some time.  Yesterday, I update the firmware on my Spark and again, right after take off, I found the drone to be out of control.  My flight log can be viewed here: https://www.phantomhelp.com/LogViewer/28ZCZ28XXKT2XRSOJHGG. .

The flight ended abrubtly when the drone got caught in a tree before falling and hitting the ground hard and braking a piece of the drone off.  I reviewed the logs and it appears from my limited experience reviewing log files, that the flight was flying too fast to control. I appreciate any suggestions as to a possible fix.  Thank you. John

Hi,

To me it seems that battery is defective. /Way/ too much cell voltage difference.
Spark wanted to land automatically because of that.

Hi! Thanks for everyone’s responses. I also wanted to add that it was refusing to land. Thanks for your help!

Hi,

Had a look at your flight.

Your VPS height sensor did measure/indicate the whole flight some low values.
That is the rerason why it entered few times a forcelanding. (100% down stick + low VPS height > landing)

The autolanding was initiated by you and cancelled again by you.

Indeed max 234 mVolts deviation, too much but imo not the reason for this weird flight.

Many times a SpeedErrorLarge ; wich means that the GPS position and the GPS calculation by the IMU are not in sync.

DJI should help you out.
cheers
