    X-tail and interesting, small planes - designed for speed? Or does the design of the rudder as a whole make it more efficient? Excellent photos, thank you for posting!
    If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

      Also a cool sail retractable cover, would like to see that replicated in a model :)

        Those rudders are crazy! In practice, x-tails are about 40% more efficient than standard cruciform, so perhaps they can get away with the control surfaces 40% smaller?

          Its interesting that there's a slot in front of the control surface.. You generally only see those in high lift devices, they prevent airflow separation at high angles of attack. I would think they get noisy, though.

            Don't know if it's noisy, but you can see same device on Le Redoutable class SSBN (here in the Cherbourg Museum).
