Yokomo YOKYTSS1 Silver Solder for RC Power Connections  [YOKYTSS1]

Electrical solder for scale RC models

This solder wire is described as a specialist option for electrical joints in RC models where silver-plated conductors are present. Many silicone-insulated RC cables feature a silvered conductor surface to aid conductivity, and ordinary tin-based soldering can sometimes erode that surface or encourage migration of silver, which may compromise joint conductivity over time.

The YOKYTSS1 racing silver solder incorporates silver into the alloy to better match silver-plated conductors and to mitigate galvanic effects at joints between dissimilar metals. In real use this helps keep contact resistance low at battery leads, motor leads and other common power connections on model cars.

For bench or field soldering tasks, the product is intended to secure electrical continuity rather than add mechanical strength. Standard practice for small RC wiring applies: clean the surfaces, apply solder so it flows to both parts, and avoid excessive heating that could damage insulation or adjacent components. Expect modestly different flow and wetting compared with standard tin solder when working with silver-plated wires.
