The plans call for using 8 inches - 16 inches of the wing cord. So forward point would be 8 inches aft of the wings front edge. Aft would be 16 inches. This is for the RAF 48 airfoil. I wonder if the new airfoil would be different

KR> weight and balance

Most aircraft use 15% to 35% mac. The forward limit is influenced by the distance to the horizontal and size. The aft limit is not. I think most go wrong in the mac. The mac for a kr2s is slightly smaller than for a KR2 and the plans are for a kr2. The governing factors are taper and sweep.
