Ed, the info I received from Don at Eureka, from Jim Martins origional drawing shows the barn doors controlled by 5/32 tork rods. I agree that bell cranks would be inviting disaster. If i go the bd route I will probably use the modern 2 servo situation. Although this install might mess with the aerodynamics on the outer wing surface. Seeing this thing is going ballistic speeds I'm not sure what effect the drag outboard on the wing might have........any thoughts? Freebird, If just one person learns a new technic it will make all the extra effort well worth your trouble in my mind. Not everyone has 35+ years of building experience. I doubt I would have thought of a scarf joint on the stab so I've already learned something from a fellow modeler. Thanks for your continuing efforts......Sugarfox

I'm going with strip ailerons and a servo in each wing panel. I'm also going with conventional retracts (you can leave them down and be legal for BPA). I want to capture the essence of the Banshee. I'm not concerned about complete scale accuracy.
Some forms of 5/32" wire will act as torsion rods and will store and release energy. While other forms are very stiff and not springy at all. If one could find the non springy wire, I suppose the torque rods would be okay. But I've only seen that non springy wire upon occasion over the years. I don't even know the correct name for it in order to find it today. Too much of a hassle for me.
I suppose one could mount a small, high quality servo out in the wingtip(s) and do justice to the authenticity of the model, but that is too much work for me.
