Hobbyists aiming for stronger, more reliable servos will find the KO Propo 35559 Aluminium Gear Set a sensible upgrade. Made with the RSx1/3-12 range in mind, it replaces fragile plastic gears to reduce failures and keep steering sharp.
The metal gear construction resists wear and keeps backlash low, which helps maintain consistent control inputs on technical sections and during aggressive cornering. You will notice steadier centring over time.
These gears are produced to match RSx1/3-12 dimensions for a straightforward swap. Installation requires standard tools and basic care to ensure correct mesh and smooth rotation.
