Woody, I don't know about the FB one. I own a PST wich is 73"L x 73"S. Only 3,3/4" shorter and 1/4" less in span than the FB. The proyected weigth is 22pounds dry and it should fly very good with a 14 thrust pound engine. I'm also concern about power to weigth ratio but everybody who flew one told me I should be OK with my pst 600r.. Terry is flying one with an wren SS and flys aweson. For me the FB is too heavy for the size. I'm very happy with mine and haven't test fly her yet. Just my opinion.
