Race-grade Precision from KO Propo 30138

The KO Propo 30138 - RSx4s-one10X ICS Digital Servo blends tight control and rugged build for 1/10 scale RC cars. Compatible with Lipo, Life and Ni-MH power sources, this high-voltage unit delivers fast, repeatable steering and throttle responses for both electric and gas platforms.

Durable Design for Competitive Use

Featuring a coreless motor and dual ball bearings, the servo gives smooth, low-friction movement under load. Hard alumite aluminum gears provide wear resistance, while the integrated aluminum heat sink helps manage temperatures during extended track sessions. At 7.4V it achieves 0.09sec per 60 degrees and produces 12.5Kg-cm of torque to handle aggressive driving.

Specifications

  • Torque: 12.5Kg-cm (at 7.4V)
  • Speed: 0.09sec/60deg (at 7.4V)
  • Dimensions: 40.5x26x21mm
  • Weight: 50.5g
  • Operating Voltage: 6.0~7.4V
  • Motor Type: Coreless
  • Gear Material: Hard Alumite Aluminum
  • Connector: Gold Plated

A straightforward upgrade for hobbyists wanting sharper control and reliable hardware in 1/10 scale racing and club runs.
Remark :
Due to limited stock availability, please notice that some KO Propo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this servo fit standard 1/10 touring car mounts?

Yes. With overall dimensions of 40.5x26x21mm, the servo matches common 1/10 mount patterns, but check horn compatibility and chassis clearance before final installation.

What batteries and voltages work best with this unit?

The operating range is 6.0 to 7.4V, so 2S LiPo packs or equivalent Life/Ni-MH arrangements are appropriate. Ensure your BEC or receiver battery can supply stable voltage at peak load.

How should I maintain the bearings and gears?

Inspect for play and contamination regularly, remove grit, and use light gear grease where recommended. Keep the heat sink clear of debris to maintain cooling efficiency.
