25T Aluminum Alloy Single Arm Servo Horn 61mm

25T Aluminum Alloy Single Arm Servo Horn – 61mm

Upgrade your servo linkage with this precision-machined 25T aluminum alloy single arm servo horn. At 61mm in length, it provides excellent mechanical advantage for large-scale RC aircraft, heavy robotic joints, and demanding automation linkages. The 25-tooth spline fits the most widely used servo output shafts – including popular models from the DS, BLS, CLS, and RBLS series – making it a versatile and essential accessory for any serious builder. Machined from high-strength aluminium alloy, it’s significantly more durable than standard plastic horns and won’t flex or strip under high torque loads.
