The reason that I feel that the zdz combo is better is not because of power issue it is just that is makes the plane fly better not having as much weight. This is the first plane that when something happens put the 3d elevator in and it will harrier with out a wing rock at all. I flew saddlers and loved it and flew extralongs with a da while its still a sweet plane in my openion it flew a little heavier
