This output shaft has a specific cross section called a “spline” (the “male” version of the spline), and the driving horn has the mating “female” spline. The details of the spline are found below. The driving horn is held in place using an M3 x 8mm pan head machine screw.

All three case components on the high speed and standard servos are made of injection-molded ABS plastic, whereas the middle case on the high torque is machined aluminum, anodized black. There are four screws located on the bottom case holding the servo together. Opening the servo without express permission from RobotShop / Lynxmotion staff will void the warranty.

The pins are GND, VCC+, Rx (servo receive pin) and Tx (servo transmit pin). The order of the connector pins is reversed from one side of the servo to the other. In order to receive or send a command / signal only one side needs to be connected. The other connector need only be used when adding another servo to the chain.
