SRT 815S 1:10 On-Road HV Brushless Servo SCH-SRTBH815S

The SRT 815S 1:10 On-Road HV Brushless Servo (SCH-SRTBH815S) is a high-voltage digital servo for radio-controlled vehicles requiring fast response, strong holding torque and efficient operation. Its brushless motor, metal gearing and dual bearings are housed in a CNC-machined aluminium case designed to support effective cooling. The standard-size format makes it suitable for vehicles that can benefit from a high-quality servo, while the 2 μsec dead band supports precise control. Suggested compatibility includes 1:10 electric touring cars, 1:10 2WD electric buggies, 1:8 electric GP models, 1:10 nitro touring cars and Formula One models.

Features

The 815S supports SR, SSR, SFR, SUR and SXR ultra-high-speed modes, providing flexibility across compatible control systems. It operates from 6.0V to 8.4V and delivers progressively higher torque as voltage increases, reaching 15.0kg.cm at 8.4V. Its direct-drive potentiometer and pulse-width control system are designed for consistent servo operation, while the included 180mm JR connector wire supports straightforward installation. A one-year limited warranty is also provided by SRT.
