Castle Wire is a premium-quality wire designed for use in the RC hobby and is the same wire used on all Castle Creations ESCs and motors. Built with high strand count, silicone-coated copper, it is engineered for high-performance electric power systems where low resistance and reliable conductivity are essential. Its low-resistance design helps deliver more power from the battery to the motor with less energy lost as heat, improving overall system efficiency.
In sensorless brushless systems, the extremely low resistance of Castle Wire also helps the ESC accurately read low-voltage back EMF signals, contributing to smooth and consistent motor starts. The ultra-high strand count and silicone insulation make the wire highly flexible, reducing the risk of work hardening and breakage during use. Available in red, black, and white, it is sold in 24", 36", or 60" lengths depending on gauge.
Warnings:
Do not exceed more than 18 inches of total wire between the battery and ESC, including existing wire on both components
Do not solder wires directly to the circuit board, as this will damage the ESC and void the warranty
