The Savox SB-2290SG is a monster torque standard-size digital HV servo built for demanding RC applications that need extreme power, strong holding force and reliable control. With up to 70kg-cm of torque at 8.4V, this servo is well suited to heavy-duty steering and control setups in large RC cars, monster trucks, crawlers, large aircraft and other high-load models.

Built with a brushless motor, steel gears, 3 precision ball bearings and a full aluminium case, the SB-2290SG delivers excellent strength, efficiency and durability under load. The aluminium case helps improve heat dissipation, while the steel gear train provides the toughness needed for high-torque applications.

The SB-2290SG operates from 6.0V to 8.4V, allowing strong performance across common HV setups. It also features a 25T output spline, JR universal connector with black lead, and water/dust resistance for added protection in demanding RC environments.
