SUMMARY
The optimal location for a wing spar in the S1223 airfoil, which has a 17-inch chord, is approximately at the aerodynamic center, situated about one-quarter of the chord from the leading edge. This position is critical as it is where the lift acts most effectively. Additionally, the spar should be placed where the airfoil is thickest to maximize structural integrity, as the strength of the spar is proportional to the square of its depth, adhering to fundamental principles of material strength.
