You are not being a pain. You are just fine. You re-worded your post and now it makes more sense as to what you may looking for. It's just that at times, some of us just can't figure out what some folks are looking for when they write here.

But, I think you are looking for wires for the control rods that go from the servo to the control surface, or at least the ends of those rods. Is that correct? The "spar" is in the wing and is what gives it strength. It runs along the entire length of the wing from tip to tip.

Sometimes, those rods are made of wood and have a short length of wire on each end. One end goes to the servo and has an L or a Z bend on the end. That's a bend in the shape of an L or in the shape of a Z. On the other end, is one that has a wire that is threaded and has a "clevis" on the end of that. The clevis connects to one of the holes on the control horn on the control surface (rudder, elevator, aileron) and the rod threads on to that. It is threaded so you can easily make adjustments to the length to set it up properly.

Then again, Mike has another possible solution to your question... struts. Now that I look at the picture a bit better, it could be struts too. But, you have the benefit of both possible solutions.
