I bought a Phantom 2 Vision a week ago, did all the upgrades to aircraft, controller and camera right out of the box. When flying, I can only reach altitudes of 200 - 250 FEET and "Controller Lost" and "Return Home" takes place. I even switched from CE to FCC and it made no difference. From my understanding, at minimum these are supposed to have range of 300 meters which is 984 FEET. I have also tested at multiple locations to rule out interference issues and no luck. Any ideas before I return for an exchange??
