SRT BHX8 HV Brushless Servo

The SRT BHX8 HV Brushless Servo (part number SCH-SRTBHX8) is a high-performance, high-voltage digital servo built for demanding RC use. Delivering up to 60.0 kg.cm of holding torque at 8.4V with rapid transit times down to 0.07s/60°, it combines a robust CNC‑machined aluminium case for cooling, steel metal gears, and dual bearings for precision and durability. A 25T output shaft and standard-size footprint make installation straightforward in platforms that benefit from a premium servo.
