Savox SB-2273SG+ Digital High Voltage Brushless Steel Gear Servo
The Savox SB-2273SG+ is a standard-size digital high-voltage brushless servo designed for demanding RC applications where high torque, precision and long service life are required. With 35.0 kg/cm torque at 8.4V and a speed of 0.095 sec/60° at 8.4V, this servo delivers strong steering power with fast and accurate response.
The brushless motor provides smooth operation, high efficiency and cooler operating temperatures compared to conventional motor designs. Combined with digital high-voltage servo technology and a 12-bit PCB board, the SB-2273SG+ offers precise positioning, strong holding power and consistent response under load.
The specialized steel gear train is built for strength and durability, while the aluminium/composite case provides a solid balance of rigidity, weight and heat dissipation. Thanks to its high torque output, 25T spline and water/dust-resistant protection, the SB-2273SG+ is an excellent choice for 1/8 scale buggies, RC cars, large scale aircraft and other demanding high-load applications.
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.
