 This is an OFNA CNC Machined Aluminum Single Arm Servo Horn, and is intended for use with servos that have a 23T spline output shaft. This servo horn has been CNC machined from high grade aluminum for precision and durability, and features a clamp type holding mechanism. This allows the servo horn to grip the output shaft, so if the output shaft screw vibrates loose, the servo horn will remain attached to the servo allowing you to remain in control of your model! Additionally, the linkage holes are 3mm, for versatility and universal compatibility with almost any vehicle.
