Type-N Circle Servo Horns 3pcs — Futaba FU1K17401 for S9150/52/53/54 BLS154 BLS174 (no screw)  [FU1K17401]

Type-N circle horn pack, 3pcs

This set contains three Futaba FU1K17401 Type-N circle servo horns, made for Futaba S9150/52/53/54 and BLS154/BLS174 servo models. The items are supplied without screws and serve as replacement parts or tuning accessories for scale RC models that require altered linkage geometry.

Fitting is carried out on the servo's splined output: align the horn with the spline, ensure the servo horn sits at neutral, then fasten with a correctly sized screw from your servo's hardware. As screws are not included, reuse the original screw or fit an equivalent to avoid damage to the horn or spline.

Using a Type-N circle horn changes the effective lever length and ball link position, enabling fine adjustments to steering throw, sensitivity and centring without changing programming. Make small changes and bench-test thoroughly to confirm safe, full travel and prevent binding.
