The 100 pound increase = 1 G reduction in load that has been thrown out is an approximation for a KR built to plans. In round numbers, a 800-850 pound KR should be able to take 7 Gs. Of that gross weight, approximately 700 pounds is being supported by the wings and contributes to the bending moment on the wings. If the fuselage weight increases by 100 pounds, the wings are now supporting 800 pounds. If the wing structure is unchanged, the ultimate load factor will decrease by approximately 1 G.
