Titanium Turnbuckles M1.8x32mm (pitch)(for TRex 450 series)
When you follow the 'Align-rules' you have to twist the stock links one full rotation to keep the little 'A' on the links 'face-wards'.
For fine-adjusting you very likely will need a half- or quarter- turn to get a really satisfying result.
Works very precise and very fast, because you don't have to 'peel' off those ball-links every time.
Highly recommended!
