Savox SW-1212SGB+ Black Series Digital Waterproof Coreless Steel Gear Servo
The Savox SW-1212SGB+ is a standard-size digital waterproof coreless servo from the Savox Black Series, designed for monster trucks, crawlers, scalers, boats and demanding RC applications used in wet, muddy or extreme outdoor conditions. With 52.0 kg/cm torque at 8.4V and a speed of 0.13 sec/60° at 8.4V, this servo delivers massive pulling power and reliable control for high-load RC use.
The coreless motor provides smooth, efficient and responsive operation, while the digital high-voltage controller ensures accurate positioning and consistent response. The specialized steel gear train offers excellent strength and durability, making the SW-1212SGB+ a strong choice for applications where heavy steering loads, large tyres and rough terrain place high stress on the servo.
The hybrid aluminium/composite case combines strength, cooling and reduced weight, while the Waterproof IP67 design helps protect the servo against water, mud, snow and dirt. The Black Series finish gives the servo a clean, stealth-style appearance, making it ideal for custom builds, premium crawler chassis and RC models where both performance and visual detail matter.
Thanks to its slightly taller standard-size format, 25T spline, high-torque output and waterproof construction, the SW-1212SGB+ is ideal for monster trucks, rock crawlers, scalers, 1/8 vehicles, 1/5 vehicles, boats and all-weather RC builds.
The “+” version includes additional functionality such as Soft Start and Sanwa SSR compatibility, offering improved start-up behavior and broader compatibility with advanced radio systems.
