Go to the links below for useful atmospheric data and how to calculate aircraft center of gravity.
If you have a Horizontal Tail Volume Coefficient = 0.60 (approx.) the airplane usually requires balancing at approx. 25% m.a.c. This will result in a longitudinal static margin of approx. of 20% with the neutral point at approx. 45%
