Control for twin rudders?

I just planning out a "prospective" future build at the moment and I'm looking for feedback.

Is there a simple way of controlling two rudders from one servo?

The plane that I have in mind is the KK Invader. I built one as a child and it never did perform well as a glider but I like the shape and think that it might make a nice candidate for light electric power and an RC conversion.

Should I try and mechanically link both surfaces and use a bell crank to push / pull on one of the rudders?
Would it be better to come off both sides of the servo arm with flexible push rods to control horns mounted on each rudder?
