TYPE-L small-circle horn for precise control

This Futaba FU1K17201 horn is supplied as one item and does not include packing or mounting screws. The TYPE-L small-circle configuration aligns with the mounting pattern used on the cited Futaba servos, providing a compact footprint suited to tight linkage arrangements.

Designed as a direct-replacement for the listed models, always verify spline count and bore fit on your servo prior to final fitting. Typical roles include steering and throttle or brake linkages on scale electric and nitro rigs where reduced throw and repeatable geometry help with fine control.

Fitting checklist: disconnect power before changing horns, set the servo to neutral, seat the horn completely on the spline, and secure with the correct screw from your servo or a compatible hardware pack. Once mounted, confirm full travel and adjust subtrim and endpoints to avoid binding or overtravel. Consider this part a precision accessory during tuning sessions.

Compatibility

  • S9150/52/53/54
  • BLS154
  • BLS174

Will this change servo throw noticeably?

Yes, a small-circle horn reduces effective throw compared with larger arms, so you will need to adjust endpoints or gearing to regain range if required.

How do I ensure the horn is centred correctly?

Power the radio and receiver, centre trims and servo output, then fit the horn so it sits square at neutral; use subtrim and endpoints afterward for fine alignment.

Best uses for a small-circle horn?

Small-circle horns are ideal where space is limited or when you need reduced throw for smoother control in steering and throttle linkages on scale models.
