I am strongly considering a purchase of yet another Phantom V2.0 equipped with the Gimbal 4 and a GoPro Hero 4 Black. I have read things to lead me to believe that operation/ flying radius is limited with this setup in comparison to, say, the Phantom 2 Vision I had been using up to this point. Can someone shine some light on this and/or recommend proper mods to allow for roughly 1000 m flight/ FPV radius. THANKX!!!
