Thanks for your comment. I did have prop icing once on a previous trip to the same location but it was foggy that day and the temperatures were in the teens. It is pretty surprising to have a drone return with ice on the props. Before this accident happened I had just completed 30 min. of video and there was no ice on the props at that time. The temperature was near 30 degrees, sunny with no fog and I was even using the controller without even any gloves. At the beginning of the flight log file the drone is stationary above me for about 11/2 minutes. This is because I had to stop and remove one of my jackets because I was getting warm.
HI,
Prop icing does not make the vertical speed in the log goes wrong.
With enough prop icing drone will descend, vertical speed and baro height shows both descending, motors revving up to try to keep height, amps goes high, voltage drops.
In your log only voltages recorded, end of flight during uncontrolled descend all the 4 cell values show higher values.
cheers
JJB
