This MR33 aluminum servo horn offers 2 different holes for the steering linkage. The holes are in a height of 15 and 19mm and allow different settings in your car. The horn gets mounted by a screw from the front (as always) and there is an additional small screw which gets tightened from the side to eliminate unwanted play! The servo horn has 25 teeth and fits servos like Futaba, Highest, Power HD, Muchmore and Savox.
