We have a strange problem. The error appeared on drone, which normally flies well.
Right after arming in loiter mode, without rising throttle, the drone flipped backwards as you can see in log 13-16-41. (RC1_IN is at minimum, desroll changes quickly and RCOUT obviously is flipping drone )

After the incident we removed the props, restarted drone and tried to arm again, but this time it didnt tried to flip. Log here

Can somebody explain me what happened after first arming?
Can it be caused by low outside temperature (arround 0°C) ?
