This is perfect.
I presented this in another forum because i wanted to to find the CG for my wing using this theory/diagram. Best answer i got was the typical 1/4 - 1/3 back from LE.
So i will let you gents work out the numbers and see if you came up with what i did. :P
Desired 25% chord CG.
one wing half:
Root Chord: 9.0 inches
Tip Chord: 5.5 Inches
Wing Half Span: 16.25
.
You need the leading edge sweep dimension also.
