EcoPower Aluminum Clamping Servo Horn
New from A-Main Hobbies is their high-strength EcoPower Aluminium Clamping Servo Horn available for use with their EcoPower servos as well as other 25T splined servos. This extremely tough servo horn has been machined from a solid block of aluminium 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.
