25T CNC Aluminum Servo Arm – Heavy-Duty Single Arm Servo Horn

Upgrade your RC aircraft, helicopter, car, boat, or robotics project with this precision-machined 25T CNC Aluminum Servo Arm. Manufactured from high-strength aluminum alloy and finished with a durable anodized coating, this servo horn is designed to deliver superior rigidity and precise control compared to conventional plastic servo arms. Its lightweight construction minimizes rotational inertia while providing excellent resistance to flexing under high servo loads.

The single-arm design features multiple threaded linkage mounting positions, allowing users to fine-tune control throw and linkage geometry for optimum servo performance. The precision-machined 25T spline ensures a secure fit on compatible 25-tooth output shaft servos, making it suitable for demanding RC and UAV applications.

Whether used in fixed-wing aircraft, helicopters, multirotors, RC cars, boats, or robotic systems, this aluminum servo arm offers reliable performance, improved durability, and accurate control.
