Center of Gravity information
Check that CG is within tolerance
Make sure all components are installed
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
If it tips up the CG is behind your balance point
Adjust the position of your fingers until your X PlusOne balances and make note of the position of your fingers, this is the
CG
Measure the distance from the CG to the back edge of the battery compartment as shown below
The acceptable range is ⅜” to 1 ¼” from the battery compartment to the CG
TIP: You may want to mark the forward and back CG limits to make checking the CG easier.
