Tight Response from the Sanwa SRG-BZX-R

The Sanwa SRG-BZX-R is aimed at drivers who prioritise fast steering feedback and steady centring. Its coreless motor gives prompt shaft movement that helps when reacting to mid-corner corrections.

Why the Design Matters

The coreless construction reduces internal drag for quicker starts and stops, while metal gears provide the strength needed when the servo is under heavy load, keeping steering consistent.

Suitable Environments

Designed for track use and demanding hobby applications, the SRG-BZX-R performs well in touring and buggy classes where steering precision influences lap times.

Specifications

  • Torque: 12.8kg-cm (7.4V)
  • Speed: 0.07 sec/60° (7.4V)
  • Motor Type: Coreless
  • Gear Type: Metal
  • Dimensions: 40.5 x 20 x 37.2 mm
  • Weight: 55g

For those tuning a 1/10 scale racer where steering precision is key, the Sanwa SRG-BZX-R provides the speed and durability to support competitive setups.

The metal gears are designed to cope with higher torque demands, making the SRG-BZX-R suitable for heavier steering loads compared with plastic-geared units.
If your setup draws significant current, a dedicated BEC or regulated supply can help maintain stable voltage to the servo and prevent brownouts under load.
Inspect for play in the output shaft, unusual noise, or visible gear tooth damage. Replace worn gears promptly to avoid degraded steering accuracy.
