Model builders and racers who want to reduce gearbox failures will appreciate the KO Propo 35559 Aluminium Gear Set. Made with RSx1/3-12 servos in mind, the metal gears are a durable alternative to standard plastic components.
Aluminium gears resist wear and keep backlash low, helping servos hold centre and repeat inputs lap after lap. That stability translates into more predictable steering feel on technical layouts.
The set is produced to match RSx1/3-12 dimensions so it installs without complex changes. Fit the gears, check mesh and end stops, then run a few checks to confirm smooth operation.
