AC is the aerodynamic center. It appears, on quick glance, the Palo website asks you to pick the CG as a percentage of MAC and shows you how to find it..

The Whitehead formula tells you where the CG should be for a properly trimmed pattern plane

  MAC

    Ron the parentheses do help. Larry the ac is a function of the planform, only, and does include the area occupied by the fuselage.

    Can someone who is computer literate show a sample of the graphic method to determine a tapered wing ac ?
