MR33 aluminum servo horn for all servos that have a 25 tooth mount (Futaba, Savöx, Power HD etc...). The servo horn is very stable and brings a faster response to the steering (compared to a plastic horn or a servo saver). It is tightened with a smaller screw from the side in addition to the normal screw. This eliminates unwanted play even better. The servo horn has 2 different height holes for screwing in the ball head (15 and 19mm) and thus offers additional adjustment options.
