I am a newbee and very pleased with my p3pro. As with most items I purchase, if I see a way to improve or mod I will do it. In this case, I bought the bird to capture boat races from the air and so water proofing the p3 is a priority. I will be exposing each electronic board and sealing them, except the gps board witch is already enclosed behind the signal shield, begging for this bead of silicone. I am currently waiting for silicone conforming I got off ebay. Should be here in a week or so then I will begin. Cant wait.
