I just bought two vision plus's one is a v1.0 and the other is v3.0. Both when I move the quad forward and back the gimbal works fine, but side to side it doesn't stay level. Its level when it's neutral. They both some times work and then some times don't work. I just got them last Friday. And the company's I bought them from say to call phantom. But I've heard they have tolerable customer service. Any ideas? Thanks inn advance for your input.
