When yawing (rotating direction of Phantom), I notice my Phantom 2 Vision Plus V3 drifts a foot or two, at least. This was true out of the box, and was also true after updating the firmware and performing an advanced IMU calibration. I've heard of a few others having this issue, but i'm trying to find out what we have in common. Do all Phantom 2 Vision Plus v3 models have this much yaw drift, or is it simply variation between units off the dji assembly line? (I can also confirm I always calibrate compass pre-launch, and this issue occurs in GPS mode).
