This ultra duty SINGLE-HORN underslung-mount style aluminum servo arm is CNC-machined from a solid billet of 7075-T6 aircraft
aluminum, broached for the mega spline (15T ø8mm), and threaded in three places for M3 mounting hardware (on 5mm centers).
This is what you need for a K6S or MT410 with 6.3mm of clearance beneath the horn.
Installation is axially on 8mm diameter, 15T-spline shaft (lightly greased), and secured, then cinched with M3 Allen-head machine-thread bolts. Disassembly is the reverse, loosen cinch bolt, then remove securing bolt.
