I've tried all kinds of different methods and materials for rigging from sewing thread to stretched sprue and the easiest I've found by far is guitar strings! You'll need a good pair of needle-nosed pliers to hold onto the string while you cut it, but I think steel guitar strings are great! They stay straight after youo cut them and you can attach them easily with either white glue or CA. I use the high strings for rigging in 1/72 scale. It might not be totally to scale but it looks fine to my Mk. I eyeball. Here's an example of steel guitar string rigging on a recently built "what-if" A1/72 scale Ansaldo "Avanti". The fuselage is an old drop tank and the penny should give you an idea of the scale.
This method also works for rigging fictitous SPAD Triplanes:
