I couldn't find any answer on the forum, sorry if there's a thread already. This video shows my problem (please play with sound to hear it). This issue happens when I start my Phantom 2 V2 with Zenmuse H3-3D and GoPro Hero 3. I've never had any problem until now. So today I took my Hero 3 out of the gimbal to shoot some sport footage. Things started to go wrong when I placed it back in the gimbal. I actually get shaky footage, with some kind of strong interference. If I slightly touch the left knob, the vibration stops and it behaves properly. All the latest firmwares are installed. I've tried different things, none worked: 1) recalibrate the X1 in the Phantom RC software. 2) hold the GoPro in the gimbal with the original bracket or also an elastic band. 3) put some isolating tape on the left and rear knobs. Anyone with the same issue? Thanks!
