Do rudders exist?

You guys boast about this being the most advanced flight sim out there for the iPhone yet it DOES NOT have any YAW controls ie RUDDERS. Its like forgetting to add milk to cereal, you just dont do that. you can do a SIMPLE side swipe control for the rudders. How hard is it to do that? Or is it that your laggy game engine is to wimpy to handle it?
