Futaba FU1K17401 3pc Type-N Circle Servo Horn Kit for S9150/52/53/54 and BLS154/BLS174 (w/o screw)  [FU1K17401]

Three-piece Type-N circle horn kit

Included are three Futaba FU1K17401 Type-N circle servo horns intended for Futaba S9150/52/53/54 and BLS154/BLS174 servos. The horns are sold without mounting screws and are aimed at hobbyists needing quick replacement parts or tuning options for scale RC linkages.

To install, match the horn to the servo output spline, centre the servo, then attach with a correctly sized screw from your servo accessories or the original hardware. Screws are not included, so use the existing fastening hardware or a precise equivalent to protect the spline and horn integrity.

Switching to a Type-N circle horn modifies effective lever arm and ball link locations, allowing subtle control over steering throw, sensitivity and centring without reprogramming. Adjust gradually and bench-test to confirm full travel and eliminate binding.
