Juice,

I made a mistake in my post. In your original system, the connect point between the cable and the elevator control arm will need to move up and down as the elevator is deflected, while the cable wants to keep traveling in its straight line. You could just allow the cable to stretch a little bit, but I don't like that idea. You either need the pulley to have the torque rod as its axle, or use rigid rods connecting to symmetric control arms on the top and bottom of the torque rod. If you simply don't have clearance inside, you might be able to do something with a bell crank in the back, and a coupling between one of the rods and the elevator control arm, but it may be difficult to get the motion of the push/pull rod and the elevator control arm to be identical. Maybe a simple system with one push rod, and careful attention to avoid flutter in the elevator?

Good luck,
