Personally I think that just 650kgs is needed, not 760, but an increase none the less over the current 600..
My roll cage will add almost 10 kgs by the time it's completely done, some other weight increases due to seriously cutting both costs and ease of construction, are you suggesting the status quo of expensive planes, as well as this, are acceptable?
I want to build safer, cheaper aircraft, it requires a tad more weight if fat blokes, which, speaking of status quo, there is a lot of about now, want to be included.
Plane manufacturers and the Governing bodies simply haven't been realistic about people getting larger, both in body mass and height.
