I agree that rudder is very useful when flying a twin (OK, it's necessary) but wouldn't judge the amount needed based on ground handling.

Both my Twinstars and my Duellist needed less than 1/2 of the set rudder throw for straight and level flight. Speed will definitely effect how much rudder will be required.

The Twinstars were able to take off on one engine (25 FXs). The left was much easier than the right. It took full rudder to steer it straight down the runway. As it built up speed and the rudder started working there was less input required. After climb out and a decent speed was obtained, less than half of the throw was needed.

Hopefully that made some sense! [8D]
