Thanks, I can use that calculator. Although I did finally get the CG figured out. In the end it came out where the manual said. What fooled me was that the front of the AT6 win just squares off and goes straight across the fuselage. I put a straight edge along the tapered wing leading edge and found the gap to be one inch at the fuse. After I added that to the root chord, my calculations came out the same as the manual.

The reason I got so involved with the CG was that the plane seemed to be too nose heavy using the manual info.
