I am going to weigh my plane soon and do not have all the radios 
installed yet so I will need to calculate their addition.
Where does the weight show up?  At the FS of the panel, or at the center 
of mass of the radio?

Say you had a 10 inch long, 10 lb radio and it was installed in a panel 
at FS 90.  Will the weight show up at FS 90 or at FS 85?  (assuming that 
the mass is evenly distributed along the length of the radio)

Don't worry, I will weigh it again before I fly.  This is for planning 
purposes only.  I am concerned that I need to move my batteries.

Thanks to all you math whizzes out there..:>)
