Awww shucks. I was hoping for an Excaliber build thread.
I have considered the Excaliber several times,but never went through with it. Those twin rudders look cool. But I don't think there is any good way to make them functional. Except for looks. That said,I have owned a lot of planes with a functional rudder that didn't function all that well even though it was functioning

At any rate,congrats on the Taube. It will be unique also
