The log files showed that battery temp were 20°C at start and went up to 30°C at the end of the log.
So, battery temp were not the issue here.
The logs showed a slow, but steady increase of Amps being drawn from the battery.
This were in no correlation to the fly state the aircraft was in. (I.e. sport mode, or other 'aggressive' flying style)
Then more Amps being drawn, hence props RPM were increasing, at one point the message 'battery overcurrent' popped up.
This could indicate prop icing. Icing results in slowly decreasing lift and increasing drag, the flight controller tries to counter these effects but at some point the ESC's maxed out.
Due to the fact that the props could not produce enough lift to keep the aircraft in the air, then gravity took over ...
The OP itself came to the conclusion, that icing could be an issue here.
More details on that incident can be seen on the .DAT files on the phone/tablet. |
