This heavy duty pulley is CNC-machined from a solid billet of 7075-T6 aircraft aluminum, broached for the ISO25 spline (25T ø6mm). Installation is axially on the 6mm diameter, 25T-spline shaft (lightly greased), and secured, with M3 Allen-head machine-thread bolt. Disassembly is the reverse, begin by removing the M3 bolt securing the leader cable to the pulley, then the M3 bolt securing the pulley to the splined output shaft. What secures the cable from slipping is the figure of 8 made by 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...

M3x10mm Button Head Allen bolt - click the pull down menu for quantities of 1, 5, 25, 100, or 1000. These are used with type F-servo horns like PDRS19F-25T, and similar fork-arms. There is a blue patch of thread locker pre-applied for your convenience.

NOTE: this servo arm has a 5mm vs. 6mm spline - it's expressly for DS145CLHV micro servos only!Injection molded of fiber-filler engineering polymer, this white color single-horn micro-servo servo arm is a great choice for high performance models. Designed with 4-holes for plenty of adjustment, it's strong enough for high flight loads, but designed to break during hard impact (acting like a fuse) thus, helping protect the servo.

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? This polished aluminum servo arm is red anodized and laser etched after being CNC-machined from a solid billet of 6061 T6...

This servo arm, latch, LEFT features a slot designed for a release pin 19.5mm from center. Ideal for bomb and tow hook release mechanisms. - This latch arm, left, is slotted at 19.5mm (also show is right) - referred to as starboard and port for right and left - CNC machined of 6061-T6 aircraft aluminum we broach the inner splines - the trick to the nifty coils for the servo lead is just a bit of heat ...
