Two days ago I had an accident with my Phantom 3 (watch video)it fell into the ocean but I was able to recover it. For some reason the battery was not on when it was found so I have some hope that the electric components aside from the battery had no power when it hit the water. I immediately cleaned it with fresh water and have now fully disassembled it and cleaned with isopropyl alcohol and dried with compressed air. The only two things I didn't manage to disassemble were the gimbal motors and main motors. Both have a lot of sand in them and friction. They main motors are the "newer" 2312a motor, I did not find any info as to how to disassemble those.
