my p-2 with zenmuse h3 3d gimbal and go pro was just purchased a couple of weeks ago. i had s fly away early on and the danged compass would not calibrate in the nose down position. i seemed to have that resolved and did a couple of flights where it calibrated better than ever in the nose down position(it has always done the horizontal in less than a turn. this time it went green in less than a turn horizontally and i turned it nose down and it just went to normal flashing green instead of yellow first. the last time i used it was only about 4 miles away so i hesitatantly took it up a couple of feet and it hovered really stable. i went rt. then left then landed and then up a bit and tested again. all was perfect. then i went up a few ft. and it started going rt. i thought maybe i had a little stick activated so i let go of both to see if it would stop and hover but it just went faster to the rt. and nothing would stop it. i did not have time to put it in manual as it only flew about 20 ft. and hit a tree near a small backwater edie of the river..yep..upside down in the water! i ran in and grabbed it and started trying to get the battery out. i had turned off but when i tried to take out the battery it started to power up again and i finally got the battery out and removed the go pro,which was flashing different modes and turning off and on. i took out the battery from it after the tedious job of unscrewing the bracket. then i took it all home and took apart everything and every connector inside the phantom. i also took what i could of the gimbal apart and then took canned air and blew the excess water out of everything. then i took a warm blow dryer on high and blew everything until i had everything i could see dry. not much is exposed and i even took the naza m case off and it was dry inside.of course it could be fried already. at this point i am putting it all in my sunroom for the rest of the week just in case. i know i could put it in rice but i think it will dry like this fine as there does not seem to be much hidden except maybe in the gimbal. i did unscrew what i could of the gimbal and blow it out as well. not sure if anyone has had good luck with a fresh water dunk on these? any thoughts are welcome and prayers are in order. the worst part for me is i put it on a credit card and have not even made a payment yet..can i cry now?
