Help with Rotation

I have noticed my DJI Phantom Vision+ has developed a strange behavior.

When I have it up in the sky and rotate it either clockwise or counterclockwise its rotation point seems to be over a motor and not the center of the Phantom.  Has anyone else experienced this?  Is there a calibration I can perform that deals with the way the Phantom rotates?  Last I checked all calibrations were within limits and the Phantom has no modifications that would throw off it's CG.

Thanks,
Ryan

Hello Ryan,  I would not consider that to be a problem.  There are a number of much more concerning things that can happen to the Phantom.

I would look at the Advanced IMU calibration for a fix on that if you feel the need.

Well as with any calibration it needs to be done correctly.
IMU as the name says is the Internal Measurement Unit, it needs to be calibrated now and then to keep the Phantom flying level.
But it must be done on a completely level surface.

Thank you very much Tom.  What you have experienced is exactly what I'm experiencing now.  So frustrating.

John is right the calibration must be on a level surface.  The problem is the electronic component inside the P2 my be slightly askew.  This is what cause it to rotate slightly off center.  Mine rotates around a imaginary point between the two front motors.
