I've had a couple of threads posted in the P2V+ Help forum about a per roblem I'm having, but I'm wondering if it's something that could happen with other DJI models as well. Over the past several months, on several different Phantoms, with several different gimbals, controllers, NAZA modules, etc, I've had a problem with the camera rolling to the left or right on its own. Sometimes it happens in a turn, but then doesn't return to level. Other times the camera just rolls off-level when the Phantom is level. There's no pattern I can see. I even bought a brand new in the box gimbal, but it's doing the same thing. I've tried calibrating the IMU in different places. I think I've tried everything. Has anyone else ever experienced this?
