Crashed into the ocean

[cronkflyer]

Just spent a great week on Grand Cayman Island, amazing place to fly your Mavic. That was until my last flight, just a few hours before checking out of the resort to fly home.

Decided I would like some video from max flight altitude, 500 meters.
When to end of pier, and flew 300m off shore to reef then up to 500m. On return I descended to 4 m above reef then in sport mode came back towards pier at 60kph, at 50m out from pier Mavic hit the ocean.

Thought maybe I had in error provide left joy stick input that caused the descent and crash. On review of flight log there were no inputs to left joy stick, only right stick forward input.

Would appear that horizontal flight accuracy at speed is plus minus at least 3m, well greater than specified by DJI. Fly with caution if you within 3m of ground / ocean

On the upside, when for a quick snorkel, recovered drone, washed in distilled water, packed in rice. It's now been 6 day in rice. Just tested an all works, only issues are battery is shot, and camera lens has water droplets on inside causing a haze in video.

Does anyone have any idea on how to dry inside of camera lens. Should I attempt to take apart? Has any tried this?

More time in the desiccant rice. Warm it up gently also, to encourage evaporation. I dry things out by laying a large box fan across two chairs, blowing downward, then resting objects on the suction side of the box fan. If water can get in, it can get out.

Thanks, I will take your advise, add heat and give it another week in rice. These are really well built drones

Wow! You're an absolute Madman for fishing that thing out of the ocean! I've never heard of this before, and must say, Congratulations! Sadly, though, I've read, and it seems logical, that sodium has deleterious effects on electronics that are not immediately evident when first dried out. But you'll dine out for years on the story!

Makes ya downright sick when it happens doesn't it. Glad you got it back! Let us know how it goes with the heat+rice!

How about putting your oven on lowest setting and putting it in there. Even with the door to the oven open it should still get enough heat to speed up the drying process.
