I flew my P3A over the water yesterday. And it too far to see the quad with naked eyes. So I look through my phone. It was about 1km away. Everything was ok, 20 GPS signals, remote controller signal is full bar, got only an image weak alert. Then tragic happened. I saw the camera flip a lot then the quad disconnected. I asked a local diver nearby to salvage the quad. The camera gimbal was cracked and fell off. It was sunken for about 15 mins. After cleaning, drying session. I put in a new battery and start it up. It starts with a gimbal error. So I can't start the motor to check if other things are malfunctioned or not. I check other parts status in DJI app and all of them are normal. So I guess it would take off again after replacing the gimbal & camera. I have some questions: Is there anything I should check physically? How do I view the crash reason? Can I claim warranty from DJI if the crash reason is some bird (or jerk) attack my quad? This is my flight record: Phantom Log Viewer - PhantomHelp.com Got a lot of speed error before crash.
