Cross-arm style servo horn details

The Futaba FU1K29401 is a metal cross-arm servo horn supplied in a pair and intended as an aftermarket replacement for compatible Futaba servos, offering a solid mechanical link between the servo spline and external linkage rods. The description keeps the focus on fitment and basic function rather than system-level modifications.

Compatibility is restricted to the listed Futaba servo models and the item is supplied without packaging or mounting hardware, so plan to source the correct screws for your application. The cross-arm design offers two orthogonal attachment points that can be used to alter throw and leverage during setup or testing.

Suitable for quick swaps or modest upgrades, this horn can help reduce play at the linkage and let you experiment with different arm lengths on 1/10 scale RC steering systems.

Compatibility

  • S3108
  • S3110
  • S3111
  • S3114
  • S3154

What is the construction and how durable is it?

This FU1K29401 horn is described as metal construction, giving it greater resistance to wear and impact than typical plastic arms. It is suitable for routine RC use but durability will depend on load and crash exposure.

Will this reduce long term play in the linkage?

Replacing worn plastic arms with a metal cross-arm can reduce free play where fitment is tight, but overall results depend on servo spline condition and linkage hardware choices.

Are there special care notes to extend service life?

Inspect the spline and mounting screws regularly, avoid over-torquing fasteners, and replace any bent linkages after impacts to keep the horn performing reliably.
