Servo Overview:
The KST SV4012-12 Aluminum Low Profile Brushless Super High Voltage Metal Gear Servo is a high-performance solution for RC cars, fixed-wing aircraft, and robotics where space efficiency, strength, and speed are critical. Designed for Super High Voltage (SHV) operation, it supports twelve-volt DC or direct drive from up to a 3S LiPo battery, with a wide voltage range of 8.4V to 13.0V. Its low-profile design makes it ideal for installations with limited space, without compromising torque or responsiveness.
About the Metal Gear SHV Servo
Power & Durability
