I have the H3-2D gimbal which works great for stabilizing the 4 even with it's extra 14 grams. But it will not transmit video. Has anybody else had the chance to check FPV with the 2D or 3D? I've updated to the latest firmware on both gimbal and camera. I've checked the settings and everything is matching with the 3 and 4. Something has changed with the 4 but I will continue to play around and see if I've missed something.
