I just flew my p3p out about 200 ft off the deck and over the ocean about 150 ft. It was doing great and then all of a sudden it lost power. It plunged into the ocean like I have never seen before. My heart skipped a beat. I saved and saved for this thing and eventually had to trade a truck to get one. It was too far out to swim for it. My wife is extremely mad and I'm hoping it washes up on shore tonight and I can retrieve it tomorrow. This post was really to let people know...it doesn't matter how much you trust your drone. If you want to keep it..don't go over water.
