I've just received the Phantom 2 with H3-3D gimbal. After attaching the gimbal initially it seemed to work fine...the tilt controls worked perfectly. However, I've now upgraded the firmware and this seems to have knackered something. After turning on the Phantom the gimbal initialises then seems to lock up and repeats, as follows... https://www.youtube.com/watch?v=wEbOQYkf09U The tilt control on the remote does nothing. There seem to be a few people who've had the same problem but I can't seem to find a solution. I really hope I don't have to send it back as I've only just received it, and it took a month to come! Many thanks in advance.
