twin rudders

I did a Beech 18 twin rudder setup, and used a bellcrank buried in the horizontal stabilizer driving two pushrods,1/32 wire takes the little bending it gets just fine. I ran the wires in tubes out to the rudders who had tiller arms running forward into the vertical stabilizers. Not much of a way to avoid exposing the tillers, but the eye, at least mine, isn't drawn to them and I think it's a tolerable bit of model-building applied to a model. And the Beech had empennage hingelines all in the same plane, so I would have had no opportunity to try out that ultra-slick idea of using the elevator hinge wire as a rudder pushrod, which requires that the rudder hinge be offset from the elevator by the distance the pushrod is offset from the rudder. But I can use it on my Twin Lizzie....
