<p>Dr. Andy Elliot (a PhD in Aeronautical Engineering) registered his 601XL (basically the same plane as a 650) at 1400 pounds. He certainly has the engineering background to make a reasoned decision on that one. If I recall correctly, it was originally at a bit higher weight but was reduced to 1400 pounds when he did the "B" upgrade, just to be sure. His CG envelope gets tighter at the higher gross weight (once you pass the 1320 weight the kit uses as a max gross) and he calls the higher…</p>

His CG envelope gets tighter at the higher gross weight (once you pass the 1320 weight the kit uses as a max gross) and he calls the higher weight a "cross country weight" which infers it is only a good idea to use that weight in smooth cruise type flight, not romping around playing fighter pilot. </p>
