Thanks for the props. When I was researching techniques and materials while getting ready for this build, most of the articles and SBS tips suggested that the consensus among small scale aircraft builders was that one of the elastic threads (EZ Line, Infini Models, Usche, etc.) was the way to go. Most of those guys used a technique that anchored one end of the thread in a “blind” hole and the other end was passed through a “through” hole. The excess was then trimmed and the hole filled (usually with just a small dab of paint).
There are a number of very fine gages that can be found for these elastic threads, too. For example, in my photos above, the Infini Models line that I used was the LARGEST size they sell. They have several smaller sizes.
That actually motivated me to use a similar technique on some of the fuselage framing (inside the tail skid well) and the control surface supporting wires (on the trailing edges of the control horns).
Interestingly enough, the second most common approach with the small scale plane builders was to just simply omit most or all of the rigging under the idea that there’s no way to accurately replicate it in the smaller scales and if it could be done accurately, it would be essentially invisible.
After these two general approaches (which seemed to be about equally represented), there were a lot of other interesting ideas and techniques used by the outliers. One guy did some really impressive small scale rigging using HAIR as the material for the lines. Several used vey fine stainless steel wire originally intended as a suture for surgery.
Anyway, the majority of small scale rigged aircraft I studied used one of the elastic thread materials.
Finally, another research / study direction are modeler who build age-of-steam and newer ship models. Those guys have their own collective, community ideas, techniques, and materials for replicating the rigging on their ship models (many of which use the same kinds of elastic thread materials). Anyone looking for ideas about rigging materials might find some amongst the ship modeling crowd.
