I did fly my copter on top of water (fountains in a park) and at some moment copter felt down in water (my mistake).
It was a Hero2 installed and running on the copter.
I did not have the water case for hero2, just the lens protection from LayerLens (link below).
After drying with heat gun all electronics from copter (APM, ESC, motors, etc) and Hero2 (I did remove the battery and open the Hero case inside), I was surprised all is working as before, not any issue.
Except the image of Hero2 is like not such bright as before. Maybe is just a personal impression.
My question is if it is possible water to enter between the lens and the CMOS sensor.
When I did look at the lens (seconds after immersion) I did not see water inside.
If water was possible to enter behind the lens and touch the sensor, maybe I need to remove the lens and clean it. But I did notice (from other posts) the sensor is somehow "incapsulated" with lens.
I did not remove the original lens until now.
Thanks,C

Hi C.,
Next time (hopefully for you there won't be any next time) turn off the equipment immediately, dismantle everything you can, dry with some paper towel and put in dry rice for the night (rice is a good natural dessicant). Heat gun may damage sensitive electronics.
Main issues when dropped in water are short circuits (immediate effect) and oxidation/corrosion of metallic parts (long term effect if not dried correctly).
On the Gopro optical parts you may have some haze or residues caused by humidity. Try to look thru with good direct light. I would be very surprised if water had time to go inside the optical assembly as it is certainly very tightly fitted to prevent dust.
Note: I have seen some of your videos and it is cool to see our city and surroundings from this angle (I live in the same area).
