I remade the rudder using 3oz satin fabric rather than the previous 9oz. All other construction remained the same.
I ended up saving nearly 1oz (2.82oz/79.9g compared to 3.70oz/104.7g), a 24% weight savings. It still feels bullet proof with no noticeable flexibility. I could probably drop down to 1.5oz cloth for a little extra weight savings.
The second version came out with much better quality than the first one, so I'll call the second one a flight part. Time to move on to the inner flaps.
