Might there be a market for somebody to offer hollow connectors here? Perhaps they would require too fine casting for the smaller scales, but I would think they would be viable in 1/32 scale.
I'm thinking here of a cast unit representing an RAF-type connector or indeed the various LK options. The unit would look like the complete apparatus from attachment point to bare wire or RAF wire, but with a small diameter hole through the middle.
You would thread two of these onto fishing line, microline, or eaziline and then run the line between holes in wings etc. You could use the old technique of going right through the wing if preferred. Once the line was fixed you would just slide a connector to each end and secure with a drop of thin CA.
I think this would be much simpler and quicker than current methods. Only drawback would be that the line would be continuous with no visible space in turnbuckle where appropriate, but this might be rectifiable and anyway these usually cannot be seen even in good quality photographs.
I'm really thinking of solid connectors with a fine guide hole which could be drilled out. Since there would be no need for any strength, they could be moulded from standard plastic or resin.
If any of the after market guys think there is any mileage in this idea, please feel free to use it - but I'll happily accept a few free test shots!
