My h3-2d gimbal broke and I've ordered the h3-3d to replace it. I noticed that the h3-3d has a usb male that plugs into the side of the goPro. My h2-3d didn't have that and I used that usb port on the camera for the fat shark transmitter. Why does the gimbal need that port and can I not plug the gimbal in there and plug the fat shark in instead?
