I was hurting for room, so I cut U360 mounting bracket.  Took about 1/8" off so I could mount it next to an 8-way.   Problem is, I think the magnet in the U360 is picking up the something in that 8-way.  
This is tough to explain.  So let me explain the position of the sticks.  
This is a SlikStik Fighter Control Panel.
I mounted a U360 to the Left of the Right 8-way.  The U360 is unable to get anywhere close to the bottom left hand corner in the joystick calibration.  By this I mean it goes from the left postion straight to the down position.  So, my problems seems to occur when the magnet is closest to my 8-way.
Am I way off of thinking this is my problem?  If this is my problem, can anything be done about it?   At this point moving the stick is not an option.
