This one took a bit of thinking, and several changes of mind between a) fitting a micro servo right next to the rudder and b) making a mechanical linkage actuated by a rod running forward under the rear deck into the main bay where everything else lives. In the end, it was tight, but the micro servo option worked out fine. I can still remove it if it ever fails or gets wet.

The rudder and prop shaft are now also glued in, and the hull filled and sealed, so we're pretty much ready for painting.

Before that though, I want to hook up the motor and ESC, and see if she floats!
