Futaba FUSHORN-K Standard Servo Horn Type-K Heavy Duty T-Arm D6mm 3pcs  [FUSHORN-K]

Standard T-arm servo horn

This Futaba FUSHORN-K Type-K T-arm is an RC-scale servo horn intended for use with Futaba standard splined servos. Its name denotes a heavy-duty T-arm form factor with a D6mm designation and it is supplied as a 3 pcs pack without screws. The part is used where a compact T-style horn is needed to link the servo output to steering or other control linkages.

Installation notes: confirm spline engagement before final tightening and test full travel to avoid binding. Because screws are not included, use the appropriate thread type and length for your servo case as specified by the servo manufacturer. When fitting multiple horns for geometry trials, mark alignment to preserve centre position during swaps.

Tuning role: a T-arm horn provides direct leverage control for tuning throw and responsiveness. Swapping mounting positions or arm lengths changes mechanical advantage and can help fine-tune steering feel or control surface response without altering servo endpoints.
