If the KR2 is built to plans, the spars and wafs will support 7G at 800 #. At 1200 # the max G is 4.667 Except at landing, having fuel in the wings will reduce the loading on the wafs since the fuel weight creates a downward force countering the force of lift that the wings transmit to the wafs. My previous hair split was important since a significant % of light aircraft fatalities are caused by pilots overshooting the turn to final, tightening the turn by increasing the bank and back pressure, but not increasing the speed. This causes the angle of attack increase leading to a stall and a low altitude spin. It appears that too many pilots out there are not sufficiently aware of G impact on stall speed. This one of the reasons that I plan to add an angle of attack meter to my plane. It will tell me immediately as I approach a stall angle of attack.
