Yokomo YOKYTSS1 RC Silver Solder for Battery and Motor Leads  [YOKYTSS1]

RC wiring silver solder guide

This solder wire is supplied as a targeted choice for RC electrical joints where conductors carry a silver finish. In many silicone-insulated RC cables the conductor is silver-plated to enhance conductivity, and using plain tin solder can sometimes remove or disturb that surface, potentially increasing resistance at the joint over time.

The YOKYTSS1 racing silver solder adds silver to the alloy to better match silver-plated conductors and to reduce galvanic tendencies that occur when different metals meet at a solder joint. In application this helps maintain low contact resistance on battery leads, motor leads, and other power wiring used in radio controlled vehicles.

For both field repairs and workshop work, this material is intended to preserve electrical continuity rather than to act as a structural filler. Standard small-wire soldering practice applies: clean joint surfaces, ensure solder wets both parts, and avoid excessive heat that can damage insulation or nearby components. You will notice some differences in flow compared with standard tin solder when working on silvered conductors.
