I just installed the x2 phantomount wide gimbal and everything seems fine until I put the Gopro on. Tilting up and down perferct, but the horizon axis is very shaky. When you tip the phantom sideways, the camera keeps level but it is very shaky, moving in small shaky increments to keep it level. Anyone come up with a fix for this. I played around with the gimbal settings but nothing seems to help. As soon as I remove the Gopro, this does not seem to happen. It is a weight issue I presume. Is my gimbal defective?
