My winter project was an original design 96'' span using two wing panels with double taper to wit the the Aircraft Center of Gravity Calculator listed in the sticky on this forum was used and it nailed the CG. I've tested both fore and aft and come back to the recommended point.
Cost was a note or appreciation to those who provided the reference.
There are actually two CG applications listed in the sticky at the top of this forum. They're both essentially the same application, written by the same author. They both consider the features that affect the pitch stability of an AC.
