Zinc-plated

steel thimbles

Kavan in Germany makes these extraordinary strong for fine adjustment of flying and bracing wires on scale model airplanes.


We went ahead and had our own tensile strength tests done and the results surpassed what we were hoping for.The M2 nickel-plated brass turnbuckles held up to 100lbs each while the M3 brass turnbuckles held up to 350lbs each.


If you do the math you will see how these two turnbuckles will serve all your miniature aircraft needs.


Dr. Vogelsang is using the M3s on his 1:2.2 scale Fly Baby as well as his 1:2 scale Bücker Jungmeister. The M2s find use in tailfeather applications, for example.
