Deezil this may be a surprise to you but not everyone will watch your video of the flight replay in an effort to ascertain what you question may be. Perhaps some will.
I watched the video and watched the sticks... From what I can tell as soon as you stopped moving the sticks. The phantom flew a bit still. Is this correct? If it is then it's nothing to worry about. It won't stop dead. You have to give it time to slow down a few seconds after you let go of the sticks. I may be wrong and not understood this at all this
I'm guessing you mean the fact that it's slowly turning right whilst you descend? I'd image it's just wind?
Unless it's causing you major issues, I'd just ignore and counter it with a bit of yaw. If you're really worried, it's probably worth recalibrating as a starting point...
