Lift up your X PlusOne and find its center of gravity by attempting to balance it on two fingers
(one on either side of the pylon, the same distance from the nose)

If the nose tips down the CG is forward of your balance point
11.
If it tips up the CG is behind your balance point
12.
Adjust the position of your fingers until your X PlusOne balances and make note of the position
of your fingers, this is the CG

below

checking the CG easier
