Savox SW-1240SG Digital High Voltage Waterproof Coreless Steel Gear Servo
The Savox SW-1240SG is a large / Rhino-size digital high-voltage waterproof coreless servo from the Savox Blue Line, designed for 1/5 scale off-road vehicles, large scale competition models and demanding waterproof RC applications. With 75.0 kg/cm torque at 8.4V and a speed of 0.15 sec/60° at 8.4V, this servo delivers extreme steering power for large-scale RC use.
The coreless motor provides smooth, efficient and responsive operation, while the digital high-voltage controller ensures accurate positioning and consistent control. The specialized steel gear train offers excellent durability and strength, making the SW-1240SG a strong choice for applications where large tyres, heavy vehicles and extreme terrain place very high loads on the servo.
The aluminium case provides strength, rigidity and improved heat dissipation, helping the servo perform reliably under heavy load. The Waterproof IP67 design protects the servo against water, mud, snow and dirt, making it ideal for large-scale off-road vehicles, boats, trail builds and all-weather RC applications.
Thanks to its Rhino-size format, 15T spline, 32-bit control board and Sanwa SSR compatibility, the SW-1240SG is built for serious 1/5 scale performance where maximum torque, waterproof protection and precise control are essential.
