Mike,

Can you provide more detail on the installation of the rudder horn? I think I know what you are saying regarding "what I have done is to open up the area between the two rudder horns completly to make a big slot and inserted a balsa former above the top horn"

However, I want to ensure that I have this right... I am planning on making a set of these for a Xtreme Composites 2.6m edge and I want to ensure that I get it right...

Thanks!
