FPV Quadcopter Awesome Crash in River and Scuba Diver Recovery
Oh dear, my Quadcopter spent over 24hrs at the bottom of a river. Here are the results of the recovered footage and how the flight was meant to happen.

Well after a good cleaning with distilled water and many days drying out, the damage was quite minimal:
1x 2200mAh 3S 25C Lipo - registered 0.05v. I had borrowed this from my spotter CamSump (sorry mate)
1x 20Amp ESC - it still ran the motor but at very low RPM and was twitchy
1x Sony PZ0420 Camera - Works perfect indoors but no longer reacts to light outside (white wash)
The flights in the video are in reverse order. I had a great flight and landed without issues, the battery alarm was not going off but I knew power was low. As I was taking my FatShark goggles off one of my spotters mentioned they saw a Common Crane (bird) in a tree, so me being someone that want to capture everything via my Quadcopter thought I would 'just' pop up to get a shot, Bad move!. I miss judge the speed I am descending and apply throttle too late.
About 10 minutes of underwater footage was recovered only due to the battery in the GoPro Hero 3 Black Edition running out. The GoPro footage captured about 25 fish in total and had the sound of Lee (spotter) and I diving into the water in search of the Quad. Underwater we could hear the battery alarm and ESC's bleeping away but could not pin point its location with only half a meters visibility in very cold murky water.
Thank you SO much to my friend Basil Brush (nickname) for coming to my Quadcopters rescue with his skills and Scuba gear, what a star. Also great thanks to CamSump and Lee for all their help and keeping me calm ;)
Has anyone else had to recover anything expensive and electrical from a river that would like to share their story and whether the item still worked afterwards?
