I have often thought the aerodynamic center was taken as a point twenty
five percent of the wing chord aft of the leading edge,. The center of
pressure is very fully discussed on page two of H. Glauberts " The
Elements of Aerofoil and Airscrew Theory", too lengthy to post here.
Copies available on Amazon.com. Regarding center of gravity, this
moves about in the center of gravity envelope which varies due to stab
area, fuselage length, aspect ratio of wing and wing area. As an
aside, most winning free flight model aircraft have their CG at a point
five percent of the wing chord forward of the back edge of the CG
envelope.
