KO Propo 35523 provides a direct replacement for the stock plastic gears in PDS-763 and PDS-764 servos, improving strength and gear mesh consistency. This upgrade reduces wear and helps maintain steady control when you are pushing your models hard.
Metal gears handle repeated high-load cycles better than plastic, so you see fewer stripped teeth and more dependable operation. For flyers and drivers who demand repeatable steering or control surface movement, metal internals mean less downtime.
The set is tailored for KO Propo PDS-763 and PDS-764 servos and installs with standard disassembly. Check gear backlash, apply appropriate grease, and ensure bearings and shafts are clean before reassembly for best longevity.
