Joe The KR2 is rated at +7/-7 G at a gross of 900lbs. A loose rule of thumb is to lose 1G per 100 lb thus at 1300lb your're looking at only +3/-3. Not sufficient margin in my opinion. Further your stall speed and thus approach speed is likely to be way up. I don't know just what the G limit relates to. It may be the wing attach fittings or it may be the engine/firewall brackets. No one I know has tested their aircraft to destruction to find out :-)). If you want a bigger useful load you would be better going to another design and probably paying more.
