DE Stubby, with 2180 VW engine, was built with many "extras", and is heavy, 564 lbs empty. This is "real world" but probably not the norm. If you resist adding anything extra, a typical DE will weigh closer to the plans weight, which I don't have available right now.
We registered this aircraft as experimental amateur built, and put the gross wt at 1100 lbs. But, we have no experience flying it at this weight.
I flew our DE with test weights in the passenger seat. We had about half fuel, 7 gallons (42 lbs), me (225 lbs) and gradually put in test weight until reaching 160 lbs. Total about 427 lbs. It flew like a dump truck, but it did fly. Needed a long take-off roll.
A partner (180 lbs) took his daughter (140 lbs) up and it flew well. Probably full fuel (84 lbs), total load 404 lbs.
So, based on this, if you build it light, it should fly a couple of 200 lb persons fairly well.
Hope that helps.
