Hopefully not! I'm getting ready my Phantom 2 (latest version) to take footage from the lake. I have flown 60 flights without any accidents (yet!!), maybe because I'm super cautious. Anyway I already have a solution to avoid it going to the bottom of the lake should it fall in the water, but I was researching about this protective spray H2OFF ELECTRIC. It a nano technology spray. It isn't cheap but it could be worth to use it to protect circuits of the phantoms. Has anyone have experience about this. Any other suggestions are greatly appreciated. By the way, here you can get an idea of what kind of lake I'm talking about.
