importance of IMU alignment

I wonder what's the importance of making sure the APM/IMU is dead center the airframe.

 

no questions about it should be at the correct 'yaw' (ie. facing the front motor)

and being parallel to the arms and not tilted.

 

but at the X,Y plane must it be at the dead center of the arms crossing ?

what is actually the center ? the center of the board ?

 

the accelerometer is not at the board's center, which makes me doubt it's important to center...

 

what do you say ?

    It doesn't have to be exactly centered, but if you want to optimize performance try to get the XY gyro near the point where the arms intersect.

     

    It's more important to ensure that your sensor filters are enabled (solder jumper) and that you've got the board mounted on some vibration-absorbing foam.
