SRT 922S HV Brushless RC Servo SCH-SRTBH922S

SRT 922S HV Brushless Servo, part number SCH-SRTBH922S, is a high-voltage digital servo for radio-controlled vehicles requiring strong torque, quick response and efficient operation. Its brushless motor, metal gearing and dual NMB main bearings are combined with a CNC-machined aluminium case to help manage heat during use. The standard-size format makes this servo a suggested compatibility choice for 1/10 2WD electric buggies, 1/10 4WD electric buggies, 1/8 nitro models and 1/8 electric models. It is also SSR mode compatible and uses a 25T output shaft, with high-resolution control and a narrow 2 μsec dead band for precise response.

The servo operates across a 6.0V to 8.4V supply range, allowing its performance to be assessed at different voltage levels. At 8.4V it provides a stated 22.0kg.cm stall torque and 0.055 seconds per 60 degrees at no load. Direct potentiometer drive, titanium and steel gear materials, and a 300 mm JR connector lead complete the practical specification. A one-year limited warranty is included by the manufacturer.
