Hexacopter with pixhawk4 mini, arducopter 4.0. Frsky 2.4GHz link. I fly in auto mode. To have good view I was control model from window on second floor my house. When I seen that RSSI was low I change mode to RTL and when model was about 600m from home I go down to go ouside to land. During This time I loose RF signal. When I was outdoor I see that model fall down. On radio last message from telemetry was “Forcing safety off for watchdog”
There is to log:
First was cut just before crash and second started during fall down.
Second log is long because pixhawk logs till I found model and switch off.
I wonder what was happens.
