Overview

The Savox SG-1211MG is a high-torque, high-voltage glider wing servo engineered specifically for the slim installation constraints of sailplane and glider wings. A full aluminum case provides secure mounting in thin wing sections, while 2S LiPo (7.4V) compatibility takes full advantage of modern high-voltage receivers and packs.

With 11.03 kg of torque and a quick 0.15 sec transit at 7.4V, the SG-1211MG delivers the authority needed to drive flap and aileron surfaces on larger gliders while maintaining the precise centering those applications demand.

Scale Capability

The SG-1211MG is engineered for medium-to-large gliders where thin wing sections demand a slim servo and HV operation provides the necessary torque and speed. Its aluminum case resists twisting under load, ensuring accurate control surface movement even on aggressive launches and fast thermal turns.
