 The servos need to be attached in their home position. To do this correctly, first power up the PCB with the new servo attached directly to the board. That will center or "home" the servo before you reattach the servo. The ear "home" position is the ears are parallel with the band. Ear position may be offset if desired, keeping in mind that the "home" position is the middle of the ear's range of motion. The servos need to be attached in their home position.

 +The servos use a 20T spline (25T is another, **different** spline that is common to encounter in hobby servos). The center screw is M2.5. Make sure your mount keeps the bottom of the ear casing free of obstructions, and that cables are arranged so that they do not resist the turning motion or pinch.
