I got a Phantom 2 Vision+ new last week. I took it out followed the setup guide and took it outside. I started the blades and then shut them off and packed up as there were too many trees around to fly. When I got to where I wanted to fly it just keeps blinking fast yellow and will not connect with my remote control. I have downloaded all the latest firmware, done an advanced cal, calibrated the remote controller, and have linked the controller to the receiver using the link button on the underside. Still constant flashing yellow. Any ideas? I have yet to get this thing off the ground.
