Forgive me for asking this question if it's already been covered, but I've searched the archives and can't find a solution - With my previous P2 (which I lost in a lake last week), if in GPS mode in a static hover, when I did a 360 rotation (left-stick), it would rotate perfectly within about a 2 foot circle or less, regardless of speed of rotation. Yesterday I received my new replacement P2 and when I attempt the same manuever it wallows around within roughly a 6 foot to 12 foot cirlce, depending on speed of rotation, then returns to the exact point in space where the maneuver began. While in a steady hover, it's rock solid. It only wanders around while rotating. My new P2 has all of the latest software and firmware updates, everything has been calibrated in Assistant v1.08, except IMU calibration which it says is "not required" when I click on the "begin calibration" link. I have done my compass calibration in the field to appease the drone gods and I'm not near any obvious souces of interference like cell phone towers, power lines, etc. Any suggestions or ideas?
