Futaba FUBS0169 Heavy Duty Aluminum Clamp Servo Horn (10-gram)  [FUBS0169]

Aluminum clamp servo horn for Futaba servos

This Futaba FUBS0169 clamp servo horn is an RC-scale servo accessory built from aluminum and specified at 10-gram mass, intended to replace a stock plastic horn when improved stiffness and longevity are required in model steering and control linkages.

The clamp design secures around the servo output, providing a simple mechanical interface that reduces play compared with some push-on horns. In practice this part is used where tighter steering response and reliable link geometry are important, such as on on-road and touring car setups or scale models with metal linkages.

Installation notes: align the horn with the servo output spline in the neutral position, slide the clamp over the output, and tighten the clamp screws evenly to avoid shifting the horn angle. Use a suitable hex driver and confirm there is no binding across the full travel before finalizing link adjustments. The aluminum construction changes the feel of the control link relative to lighter plastic horns, so re-check end points and trims after fitting.

Tuning role: this heavy-duty clamp horn helps keep linkage geometry stable under higher steering loads, which can make steering inputs feel crisper and reduce incremental slop introduced by worn plastic horns. For fine-tuning, pair the horn with properly adjusted turnbuckles or ball links and verify servo centring to maintain predictable steering geometry.

Choose this horn when you need a durable, metal clamp-style replacement for standard servo horns and when maintaining tight steering geometry is a priority in your RC model setup.
