Hi,I already made some mapping with this 3DR Plane without a problem, in this last flight the plane made 10 of the 13 waypoints and it just flew away and crashed, I managed to find the plane but I couldn't explain this behavior. Its the 3DR Pixhawk plane. The problem happens after 14 minutes of flight. Log is attached in .rar. See More
