Thanks for all the ideas and suggestions. I have a weight and balance that's already been done years ago and I believe it is the one from the manual. In reading it, it says to weigh the plane empty to get the CG and then put two 215 lb people in the plane and then weigh the plane to make sure it is still in CG. If my thinking is correct, the spreadsheet does the calculations instead of actually having to add people into the plane. Otherwise I will need much bigger scales.
