September 11th day yesterday on a flight with my mapping quadcopter with pixhawk mapping and arducopter 3.1.5.
the quadcopter at 2 minutes into the mapping mission began to spin like crazy
continued to try to regain control passing quadcopter mode stabilized but did not respond.
finally gave it up as lost when I finish spinning and regain control.
although almost did not look Placing an RTL and quadcopter return to launch point.
I learn later that solar storm yesterday had. Could it be the cause?
I leave here the log, if anyone wants to have a look
