Hi all, I am a fresh member of the forum and also a new Phantom 2 owner. I bought my Phantom second hand and it has a gimbal on it. The box says it is a Zenmuse H4-3D Edition and it has a sticker on it which also states that it is a H4-3D. BUT When I connect to DJI Phantom 2 Vision Assistant (why does it say Vision buy the way?) and go to Upgrade tap, the last item is "H3-3D IMU"??? Is that OK or have I been sold a Phantom 2 with H3-3D gimbal with a different box and a fake H4-3D label on it? Thanks for your time.
