Futaba FUSHORNA-4 Type-A Cross-Arm D6mm 4pcs Servo Horns  [FUSHORNA-4]

Standard Type-A Horn Description

This product is a set of four Type-A cross-arm servo horns designed for Futaba-style spline interfaces, supplied without screws or retail packaging. The listing specifies 4 pcs and the D6mm cross-arm dimension noted in the title.

The horns are suitable for replacing damaged arms or modifying linkage geometry. Screws are not included, so retain your existing fasteners or obtain suitable retaining screws separately. Always confirm the D6mm cross-arm interface and spline compatibility on your servo before fitting.

Fitting involves aligning the horn with the spline, seating it fully, and fastening with the correct screw for your servo. Changing the horn type or lever arm length will alter throw and leverage, which you should verify during setup to achieve desired control characteristics.
