Kyosho IFW610C - Aluminum Steering Servo Horn (SANWA/KO/18.5mm/MP10)  [KY-IFW610C]

Aluminum Steering Servo Horn Overview

This Kyosho IFW610C aluminum steering servo horn is an RC-scale replacement part intended to interface with splined servos and to provide a solid mechanical link between a servo and the steering linkage on 1/10 touring platforms such as the MP10.

Compatibility follows the product naming, matching servos that use 18.5mm splined output and common SANWA and KO spline types, so verify the servo spline pattern before fitting. The horn's role is mechanical, supplying a direct connection point to adjust steering throw, centring and endpoint behaviour through the linkage geometry rather than electronic settings.

Installation is straightforward for experienced model builders: remove the stock horn from the servo spline, align the IFW610C to the servo output splines, and secure with the original servo saver or retaining screw. Where applicable, check for correct spline engagement and minimal play, and use the vehicle's stock linkages or adjustable turnbuckles to re-establish tie-rod length and toe settings. Use appropriate hex driver sizes and avoid over-torquing small fasteners to prevent stripping.

Tuning notes: swapping to a rigid aluminum horn can reduce flex at the linkage interface, which helps maintain consistent steering ratios under load and allows finer mechanical adjustment of end points and steering sensitivity. Expect the hardware to influence feel through mechanical feedback rather than altering electronic servo behaviour, and confirm there is no binding throughout full suspension travel.
