I'm in the process of closing my rudder and building the trim tab.  I am thinking about mounting the pushrod lower on the attach bracket and cutting the top of the bracket off, allowing the entire mechanism to live internally.  I know the external arm doesn't create enough drag to worry about, but I am just not crazy about the way it works. 

 

I'm curious as to who else has attempted this and what information they can pass along.
