Technical Performance

The SG0211MG represents the pinnacle of servo engineering for glider applications, combining advanced digital technology with precision manufacturing that sets it apart from general-purpose servos. The coreless brushed motor delivers smooth, responsive performance whilst consuming just 5mA of idle current when not in use, helping preserve battery charge during extended field sessions. At 6V operation, the servo draws 180mA under no-load conditions and reaches a maximum stall current of 1900mA when locked in position, making it compatible with modern LiPo battery systems commonly used in RC gliders across the UK. The servo operates reliably across a wide temperature range of -10°C to 50°C (-14°F to 122°F), ensuring consistent performance whether you're flying on cool winter days or during warm summer soaring sessions. Measuring precisely 30.0mm in length, 10.0mm in width, and 36.0mm in height, the compact dimensions allow installation in wing sections where conventional servos would be impossible to fit. The 21-tooth output gear spline is the industry standard for servo compatibility, ensuring you have access to a wide range of replacement arms and linkage options. With an operating travel of 100 degrees (1000 to 2000 microseconds) and maximum travel capability of approximately 165 degrees (800 to 2200 microseconds), this servo provides the control range needed for precise aileron, rudder, and elevator control in glider applications. The 250mm servo lead length with 5mm tolerance provides adequate reach for most glider fuselage layouts, though extension cables are readily available if required. UK RC glider enthusiasts appreciate that this servo is backed by a comprehensive one-year warranty from Savox, providing peace of mind and protection for your investment.
