Engineered for the RSx12 servo, the KO Propo 35550 Aluminium Gear Set boosts mechanical resilience while keeping actuation tight and predictable. The kit is machined for consistent tooth profiles to reduce slop and prolong service intervals on active models.
Switching to aluminium reduces deformation under load and keeps gear engagement stable, which helps with accurate endpoint repeatability and reduces the need for frequent replacement compared with plastic gears.
These gears are compatible with KO Propo RSx12 servos and require only basic disassembly to fit. Hobbyists can perform the swap quickly and return the servo to service with minimal downtime.
