<DIV>In the .60 size pattern days, a guy in north east (Mark Scheda I believe) built a pattern bird with all flying wings - no ailerons, the entire wing pivoted to provide roll control. That added considerable mechanical complexities of course. It flew fine, but with no particular advantage apparent.</DIV>
