Finale update. As I said before the Phantom flew fairly well after the lake incident but got increasingly worse. Turning by itself, not maintaining height, drifting around.
I suspected the NAZA module thinking water got in it and I didn't open it up to dry it out like the rest of the bird. I bought another Phantom and put this one on the back burner.
Today, I installed a new NAZA module. I had replaced all four motors last month. Everything else is unchanged. Flew perfectly! Apparently the NAZA was affected by the water, even though it didn't show up initially. So I now have a backup Phantom. Yeah!
