Futaba FUSHORN-F 4pcs Type-F Cross-Arm D6mm for Futaba-standard Servos (no screws)  [FUSHORN-F]

Compact Type-F Servo Arm Overview

The Futaba FUSHORN-F Type-F cross-arm functions as a straightforward replacement for Futaba-standard servos where a D6mm cross-arm interface is required. The pack contains four matching arms and does not include fastening hardware, making it suitable for spare parts or tuning setups.

As a basic linkage component, this horn helps preserve consistent control throws, makes swapping during setup quicker, and provides a reference part for small linkage adjustments. Match the arm only to servos with Futaba-standard output splines and a 6mm cross-arm fit.

Installation notes:

• Verify spline compatibility by checking your servo manual or comparing the spline pattern to Futaba-standard before fitting.
• Screws are not part of the package; either retain factory mounting hardware or use appropriate thread and length fasteners from your parts supply.
• If altering the arm for clearance, cut conservatively and test full range of motion to ensure no binding occurs.

A practical spare set for routine setup changes or to standardize arms across multiple servos.
