Hello fellow flyers. I've had my Phantom 2 Vision for several months now. I have been experiencing an issue i've read about several times on these forums. While flying with the supplied RE500 - I frequently loose FPV around 250-300'. Ideally I would love to fly 400'-500' with semi reliable FPV. Enter what i've read about the RE700. I ordered an RE700 from Amazon last week. It came in last night! My question is - what exactly do I need to do in order to swap the RE500 fro the RE700? I've read something about scanning a QR code, but some detail would be greatly appreciated. Thanks in advance!
