The Savox SV-1257MG Plus is a mini digital high voltage servo designed for compact RC models that need extremely fast response, precise control and durable metal gears. Producing up to 6.0kg-cm of torque at 8.4V with an ultra-fast 0.045 sec/60° transit speed, it is a strong choice for helicopters, aircraft, cars and other compact high-performance RC applications where speed and accuracy are important.

Built with a coreless motor, heavy-duty metal gears, dual ball bearings and a hybrid aluminium/composite case, the SV-1257MG Plus delivers smooth, responsive performance in a lightweight 29.5g package. Its high voltage capability allows increased speed and torque from compatible 6.0V–8.4V receiver power systems, while the metal gear train provides improved durability over plastic or composite gear servos.

This Plus version also features Soft Start, helping reduce sudden servo movement when the model is powered on. With Sanwa SSR compatibility, a 12-bit PCB board, 25T output spline, water-resistant protection and standard JR connector, the SV-1257MG Plus is a premium mini HV servo for customers needing maximum speed in a compact size.
