Yeah - I shoot for about 45 degrees of throw also. Make sure both rudder blades are parallel to one another throughout their travel too.

Here is one of my boats with air rudders fitted. This boat doesn't need more than about 30 degrees of rudder throw to get good steering and control.

This is another of my boats with too small of rudders on it. It goes straight nicely but spins out easily. Putting bigger rudders on it made a remarkable difference; however I don't have a video of the boat with bigger rudders on it. This boat has 45 degrees of rudder throw.
