Im thinking of purchasing the Phantom 3 Professional, i currently have the Phantom 2 with the H3-3D gimbal and a gopro. I know about the major advertised differences, but how is to fly compared to the Phantom 2? Is it more stable , less drifting, handle winds better, or some other differences? I would like to hear from you who has the P3 and has owned or flown a P2 so that you have something to compare with. Is the difference between the P2 and P3 like night and day or is there just a little bit of difference in these things i ask about? What about the 4K camera on the P3 Professional, how is it compared to the GoPro 3+ Hero Black / Hero 4 Black, in terms of quality and functions? Would you recommend to upgrade to a P3 even if i currently have the P2? I would appreciate some input. Thanks in advance.
