KST SV915-12 High Voltage Brushless Cyclic Servo
The KST SV915-12 HV is a premium high-voltage brushless cyclic servo engineered for precision, speed, and reliability. Built for 550–700 class RC helicopters, it delivers the brute torque and smooth response required for advanced 3D maneuvers. Featuring hardened steel gears, dual ball bearings, and a CNC-machined aluminum case, the SV915-12 ensures consistent performance under the toughest flight loads—while its wide 8–13 V range supports direct HV LiPo operation without regulators.
