Good questions! On the first page of the plans, it gives to empty weight as 487 lbs. Then the wing loading at gross is 6.9 lbs at gross weight. The wing area is 143 sq. ft. That results in a gross of 986.7 lbs.On the weight and balance pages, the weight for the most forward CG is 678 lbs. with one 170 lb pilot.The most aft CG is at 910 lbs, with two pilots totaling 340 lbs. and 20 lbs of baggage.I find no mention of design G loads.
