25T (25 tooth)

CNC-machined from a solid billet of aircraft aluminum, installation is axially on the output shaft, which we advise first lightly greasing, and then securing with an M3 Allen-head machine-thread bolt. We also advise using a locking device (lock or star washer) or chemical threadlocker. 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...

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...
