Savox SH-0257MG+ Digital DC Motor Metal Gear Servo
The Savox SH-0257MG+ is a micro digital servo designed for small RC aircraft, 450 size helicopters and compact models where low weight, fast response and metal gear durability are important. With 2.2 kg/cm torque at 6.0V and a speed of 0.09 sec/60° at 6.0V, this servo delivers quick and reliable control in a compact micro-size format.
The DC core motor provides smooth and predictable operation, while the digital controller ensures accurate positioning and reliable response. The metal gear train improves durability and long service life, making the SH-0257MG+ a strong upgrade over lightweight plastic gear micro servos.
The aluminium/composite case helps improve cooling while keeping the servo lightweight. Thanks to its micro-size design, 21T spline and compact dimensions, the SH-0257MG+ is ideal for small planes, park flyers, 450 size helicopters and other compact RC applications where speed, precision and reliability are required.
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.
