You always think it won't happen to you until it does. Today I was flying over the ocean just under 400 feet and then all of a sudden the bird starts tumbling and I get the dreaded "motor obstructed" message as it continued to spin out of control and then right into the ocean. Needless to say, I am pretty bummed that my 5 month old bird is no longer, but I did manage to rack up over 600 miles in that time and have fond memories with videos and pictures. Now, as you will see in the logs, the flight only lasted 3 minutes, the battery was at 85% at the "incident" and there were no birds and obviously no trees or buildings in the ocean. The only thing i can figure is that one of the motors either seized or the mother board failed and shut down one or more of the motors. I am at a complete loss to explain why this happened which is why I am asking if anyone here might be able to shed some light on it.

Any help from any of the experts here would be really appreciated.
