SRT BHX9 HV Brushless Servo

The SRT BHX9 HV Brushless Servo (SCH-SRTBHX9) is a high-torque, high-voltage digital servo engineered for demanding RC applications. A CNC machined aluminium case provides exceptional cooling, while a brushless motor, dual bearings and steel metal gears deliver precise control, durability and efficiency. With operating speeds down to 0.10 sec/60° and stall torque up to 75.0 kg.cm at 8.4V, the BHX9 offers superior holding power and rapid response in a standard-size footprint. It is programmable and supports SXR, SUR, SR and SFR ultra high speed modes for optimised performance.
