Savox SV-1251MG+ Digital High Voltage Coreless Metal Gear Servo
The Savox SV-1251MG+ is a mini digital high-voltage coreless servo from the Savox Original Line, designed for compact RC applications where high torque, fast response and metal gear durability are required. With 10.0 kg/cm torque at 8.4V and a speed of 0.085 sec/60° at 8.4V, this servo delivers impressive performance in a very compact format.
The coreless motor provides smooth, efficient and responsive operation, while the digital high-voltage controller ensures accurate positioning and consistent response. The heavy-duty metal gear train improves durability and long service life, making the SV-1251MG+ a strong choice for demanding mini-size RC applications.
The hybrid aluminium/composite case combines strength, cooling and reduced weight, helping the servo perform reliably under higher loads. Thanks to its mini-size format, 25T spline, high-voltage capability and water-resistant protection, the SV-1251MG+ is ideal for RC cars, helicopters, airplanes and compact models where strong performance is needed in a limited mounting space.
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.
