Mark, the guy that built the plane, was an FAA engineer, DAR, commercial pilot, and a BSEE. If that counts for anything. Is it possible he built the plane a bit sturdier to achieve 2000 max gross? If so, what evidence would we look for? I am really not interested in a one person plane with 3 seats that might lose a wing if it hit an air pocket in a turn. I already own a plane with 750lb useful.
