You considered a 400 lb load on one wing due to a stalled wing during a 10 g maneuver. One way of looking at it is, is a 400lb load possible? For a wing with area of 1600in^2 (800 per side) it would take a speed of more than 350 miles per hour at a lift coefficient of 1.5 to produce 400 lbs of lift from one side. If the other side produces no lift, the roll rate would be awesome.

I think your English is excellent.
