My buddy had a Four-Star 40 that he built from a kit. He enlarged the elevator and rudder and added a counter balance to each. It was powered by a 46SF. It could hover, flat-spin, knife-edge very well. Alot of people were impressed by just how well it could do these manuvers. So with a few mods here and there it should be able to do what you want! Even if you keep it stock your going to have a very good flying plane, which can do all standard aerobatics with ease. You can always enlarge the control surfaces after you flown it for a while!
