With its combination of speed, torque, precision and durability, this micro digital servo is trusted by RC enthusiasts across the United Kingdom and beyond.

Key Features

• Strong 3-Pole Brushed Motor — The servo features a powerful 3-pole brushed motor that delivers accurate and fast response times, ensuring your RC helicopter or aeroplane responds instantly to your control inputs for precise flight dynamics.
• Metal Gear Train — Professional-grade metal gears form the solid framework of this servo, delivering exceptional durability and strength that makes 'crumbled gear' history, even under the stresses of 3D flying or rapid control inputs.
• Digital Servo Technology — Leading-edge digital servo technology provides fine resolution control and accurate positioning, giving you the precision needed for smooth, stable flight performance.
• Aluminium Centre Case — The aluminium middle case allows for improved motor cooling and maintains optimal operating temperatures, ensuring consistent performance throughout your flight sessions without thermal throttling or performance degradation.
• Ball Bearing Construction — Ball bearings ensure smooth, frictionless operation and extend the working life of the servo, providing reliability that casual users and competition pilots alike can depend upon.
• Exceptional Speed — With a speed rating of just 0.09 seconds per 60 degrees at 6 volts, this servo responds faster than larger servos, giving you the responsiveness needed for precise helicopter control and aerobatic flying.
• High Torque Output — Delivering 2.2kg/cm (30.6oz-in) of torque at 6 volts, this micro servo provides more output force than much larger servos, allowing it to handle control demands with confidence and precision.
• Ideal Servo Size — The compact 22.8 x 12.0 x 25.4mm dimensions and lightweight 14-gram construction make this servo perfect for weight-conscious builds whilst maintaining full performance capability.

Technical Performance

The Savox SH-0257MG+ delivers impressive technical specifications that make it stand out in the micro servo category. Powered by a brushed 3-pole motor and equipped with metal gears, this servo represents a significant step forward in micro servo engineering. Operating across the standard 4.8V to 6.0V voltage range, the servo provides 1.8kg/cm torque at 4.8V and 2.2kg/cm torque at 6V, with corresponding speeds of 0.13 seconds per 60 degrees at 4.8V and 0.09 seconds per 60 degrees at 6V. The aluminium composite case design enhances cooling whilst maintaining structural integrity, whilst the ball bearing construction ensures smooth operation with minimal friction. The servo features a 21-tooth spline output, operates with a 90-degree standard travel range (1000 to 2000 microseconds) and can achieve approximately 150 degrees maximum travel across the full pulse width range of 700 to 2300 microseconds. Running at 240Hz refresh rate, the servo maintains responsive control characteristics ideal for helicopter CCPM mixing and aeroplane control surfaces. Current consumption is minimal at 5mA idle, 150-180mA under no-load operation, and reaches 1000-1200mA under full stall conditions. Wire length is a generous 250mm, providing flexibility in servo placement within your aircraft. The construction quality reflects Savox's commitment to excellence, with precision engineering throughout and design principles that eliminate common servo failure modes. This is a servo built to withstand the rigours of regular flying without compromise.

Frequently Asked Questions

• Is the Savox SH-0257MG+ suitable for 450 size helicopters? — Yes, this servo is specifically designed and recommended for 450 size helicopters, whether you're flying CCPM head or tail rotor applications. The combination of fast response (0.09 seconds), adequate torque (2.2kg/cm at 6V) and lightweight design (14g) makes it ideal for this helicopter class.
• What voltage does this servo require? — The servo operates across the range of 4.8V to 6.0V, making it compatible with both 5-cell NiMH battery packs and 2S LiPo batteries commonly used in small RC helicopters and park fly aeroplanes.
• How fast is this micro servo? — This servo delivers exceptional speed of just 0.09 seconds per 60 degrees at 6 volts, making it one of the fastest servos in the micro category. At 4.8V operation, it runs at 0.13 seconds per 60 degrees, still very quick for precise flight control.
• What is the torque output? — The servo produces 2.2kg/cm (30.6oz-in) of torque at 6 volts and 1.8kg/cm at 4.8V, which is exceptional for a micro servo and allows it to handle control forces that would overwhelm smaller servos.
• Is this servo waterproof? — No, the Savox SH-0257MG+ is not waterproof. It is designed for park fly and helicopter applications in normal flight conditions and should not be exposed to water or rain.
• What type of connector does this servo use? — This servo features a standard JR-type servo connector, making it compatible with most RC receivers and control systems using JR connectors.
• What is the spline size? — The servo uses a 21-tooth spline output, which is standard for micro servos and compatible with the vast majority of micro servo horns and accessories available.
• How much does this servo weigh? — At just 14 grams (excluding wires and horns), this is an extremely lightweight servo suitable for weight-critical applications like helicopters and aeroplanes where every gram matters.
• What is the operating temperature range? — The servo operates safely between 14°F and 122°F (-10°C to 50°C), covering typical indoor and outdoor flying conditions in the UK climate.
• Does it have ball bearings? — Yes, this servo features ball bearing construction which provides smooth, frictionless operation and significantly extends the working life of the servo compared to plain bushings.
