What are some ways to keep a reletive amount of tension on rigging, and structural wires? I have some EZ line, and some .006 thous. wire. I've started a DH-9a, and need to rig the rudder bars/ rudder wires together, as well as the structural wires for the frame. In studying the drawings, I see also a "skid control wire". Is the tail skid steerable?
