I just purchased a used EVO ii version one drone with no camera. I attached my 6k camera to the drone. The gimbal works great the ribbon is tight, so it recognizes the drone. The screen on the controller is black when i hit the display button. Has anyone experienced this, and can anyone help me? I have tried everything re-hooking the camera back up. The screen is black and there is also a spinning motion on the screen the controller. any help please ! thank you Ben H
