Disassembly is the reverse. - There are 3 standard size ProModeler servos suitable for an X-MAXX  Note; and by way of heads up . . . we advise not using this control horn for servos other than our...

Unlike competitors, we have these servo-mounting screws custom forged right here in the USA. While there are 4 in a pack (enough for one servo), they're also available in quantities of 25, 100, and even 1000 (for professionals builders) because they're useful for a lot of other stuff like mounting cowls, landing gear straps, etc. What motivated us to make these? I was installing servos using a long skinny Phillips head screwdriver. It slipped off and punched a neat hole through the top of the...

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...

NOTE: this servo arm fits our DS115CLHV wing servo, which has a 5mm spline instead of the usual 6mm diameter 25T Futaba compatible spline (as used by most of our servos except the big ass 1/5th class servos, which use our even larger 8mm spline). The spline pattern for this arm is tiny so unless you want the hassle of a return to contend with, don't buy them . . . capice?
