6-horn servo arm, quantity 1, black nylon 6,6, 25T spline

21mm in OD, the round servo-horn is often referred to as a wheel-arm. Injection molded in rugged nylon 6.6, which is a type of heavy duty plastic (fiber-filler engineering polymer), this is the same stuff used in 9mm handgun frames because it's so tough. Simple in appearance but complex in execution (what makes making these actually rather pricey), the molding for this arm has a total of 13 bores (that's what we call them, but everybody else calls them holes). Of course, there's one on center...
