I just upgraded to the Phantom 2 3D gimbal. When I use the "stock" 3D USB video cable (the uber flimsy one) I have FPV video. (I have the DJI hub + VDL58 and a GoPro Hero3 Black, original Phantom2 - modded for the 3rd axis gimbal motor ) I replaced the stock flimsy cable with the GoPro Hero bus assembly from my original 2D and lost video from the GoPro. FPV telemetry is fine.. So. Any thoughts? I remember seeing a YT video where the bloke had the same issue, but of course, now I can't locate it. I think he fixed it by re-seating one of the ribbon cables. I tried this, but no joy... I ordered this: http://www.goodluckbuy.com/dji-h3-3d-3-axis-gimbal-upgrade-back-insert-av-output-part.html thinking that my original 2d cable may have a broken trace... Thoughts/comments appreciated.
