<p>Install the servos as shown, using the included 3mm hardware and two #2 tapping screws. For quick prototype assembly, you can use rivet fasteners (sold separately: <a href="https://www.lynxmotion.com/showproduct.aspx?productID=327&CategoryID=75" target="_blank">NSRF-01</a>) as illustrated. The HS-422 servo goes in the horizontal position, and the HS-475HB servo goes in the vertical position.</p>
