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

Compact Type-K T-arm Overview

The Futaba FUSHORN-K T-arm is an RC servo horn engineered for Futaba standard splined servos. It features a robust T-arm profile with a D6mm marking and is supplied in a 3 pcs pack without screws. Use it where a small T-style arm is needed to connect the servo output to steering or other control linkages.

Installation advice: ensure the spline fully seats before tightening and cycle the servo through its full travel to confirm there is no binding. As screws are excluded, match screw thread and length to the servo case according to the servo manufacturer's recommendations. For geometry trials, label each horn position so the neutral centre is preserved when changing parts.

Tuning benefit: the T-arm provides straightforward leverage adjustments for throw and response. Moving mounting holes or swapping arm lengths changes the mechanical advantage and helps fine-tune steering precision or surface response without adjusting servo endpoint settings.
