"As much as I would like to I don't see me "hanging it by the prop" or doing complex IMAC maneuvers with the Twin-Air. So the optimum rudder configuration for me is more a cosmetic thing than anything else."
While I have not built the twin rudder option on my bashed twins, I do have two aerobatic ( For me) bashed twin fuse planes, and so twin rudders, and the increase in rudder response is dramatic. Yes, they will hover quite well and single engine "Surprise" is almost a non event. I will warn you, hovering with a single rudder, unless very large is a bigger challange.
Maybe one idea to control both rudders is use three ball joint connections on a bell crank in the center of the elevator to each rudder.
Use two more ball joint type connectors at the rudders. What I am talking about is to minimize linkage play due to extra joints. A "tee type bell crank" with pull pull to the servo would be better than a push pull rod.
Why would you listen to me. I con'd a poor builder at my field to put five engines on a Kadett!!!
