I have seen streamlined aluminum tubing in various sizes in the RC shop. I'm not sure if they offer a size that would be small enough for flying wires but worth looking into. I am using these on my 1/6 scale Cub for lift and jury struts. I run a 1/6" music wire through the center for strenght, as these struts are functional. The ends are easily soldered to the wire. If they are non functional as in your case just CA the clips on the ends with a pin through the strut to hold the clip.
