I now have TWO P4s which landed in the water. I thought the first one was drone error (flyaway)while using Litchi waypoints. The second one was operator error (mine). Both landed in water. DJI support has really nice on hold music. I pretty much have the tune memorized! And the very nice person in tech support quoted a repair price for one that is MORE than the retail cost of a new P4. This question seems really dumb but I wondered if anyone has some good ideas for repairs.
