These CNC-machined aluminum servo arms are not only connected to the servo via the top mounting screw, but also secured laterally with an additional hex screw. This screw clamps the servo arm onto the output shaft, ensuring maximum grip. Another advantage is that the connection is now completely play-free, resulting in more direct steering response and reduced load on the servo gears. The tooth count is laser-engraved as a number or code, allowing easy identification of the type later on.
Because an aluminum servo horn is much stiffer than a plastic arm, all control inputs are transmitted much more directly and precisely. It is also significantly more durable than the plastic servo arms that are usually installed as standard.
