Hi,
Sorry for your loss! Your type of loss is the same reason why i sold my Spark last year.
Sometimes out of the blue this type of errors pops-up, and if the 'pilot' is not fast enough it will loose the craft, drifing away in ATTI.
Flying in ATTI is difficult, for sure if you do not have the drone visual.
During your PANO, at 5.5 meters away from your starting point the sh*t hits the fan.
Craft started to drift away from postion at 4m57s.
2 seconds later a error in the log : SpeedErrorLarge, this error seen when the actual position is not the same as the calculated IMU postion.
This error followed by a Compass error, yaw error ; Spark in ATTI mode.
You could have seen mayby the start of the drifing away from postion, as the drone was so closeby.
Problem with these errors is that they are not shown in the APP, so no pre warning that ATTI will be there.....
Yaw, compass, speed errors often seen in a random sequence, most likely that a compass error is the cause of this ATTI drift away.
Hope that DJI will help you out. IMO DJI should change the information they present the pilot, not ATTI mode now but a pre-warning for ATTI.
See the charts.
cheers
JJB
