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

IFW610C Description and Compatibility

This Kyosho IFW610C aluminum steering servo horn is an RC replacement component designed to mate with splined servos and provide a robust mechanical link between the servo output and the steering linkage on 1/10 touring chassis such as the MP10.

Compatibility is as stated in the product name: it is intended for servos using 18.5mm splined outputs and common SANWA and KO spline types. Verify your servo's spline pattern prior to fitting. The horn provides a direct mechanical point to adjust steering throw, centring and end points via linkage geometry rather than through electronic servo settings.

Installation is straightforward for those familiar with model assembly: remove the stock horn, align the IFW610C to the servo output splines, and secure it with the original retaining screw or servo saver. Check for correct spline engagement and minimal play, and use the vehicle's existing linkages or adjustable turnbuckles to re-establish tie-rod length and toe angles. Use suitable hex drivers and avoid over-torquing small fasteners to prevent damage.

Tuning notes: swapping in a rigid aluminium horn reduces flex at the linkage interface, which improves steering consistency under load and allows finer mechanical adjustment of end points and sensitivity. The change affects mechanical feedback rather than electronic behaviour, and you should confirm there is no binding over full suspension travel.
