This is a Racers Edge Large Aluminum Clamping Servo Horn, intended for use with 25 spline R/C servos. This extremely tough servo-horn has been machined from a solid block of aluminum for incredible precision, rigidity and durability. The horn features a clamp type design that grips the servo’s output shaft so if the retainer screw comes loose, the horn will have a better chance of remaining in place, decreasing the chance of the horn coming off.
