T-Arm Servo Horn Details

The Futaba FUSHORN-K Type-K T-arm is an RC servo horn intended for Futaba standard splined servos. It is a robust T-arm with a D6mm specification and comes as a 3 pcs pack without screws. The part is suitable where a compact T-style horn is needed to connect the servo output to steering or other control linkages.

Installation guidance: confirm the spline is fully engaged before tightening and verify full travel to prevent binding. Screws are not provided; select the correct thread and length per the servo manufacturer's recommendations. When testing multiple horns for setup, clearly mark centre positions to retain neutral alignment during changes.

Durability and tuning: the T-arm offers direct leverage allowing adjustments to throw and responsiveness. Changing arm positions or lengths modifies mechanical advantage and can refine steering feel or control surface reaction without altering endpoint settings.
