Swap to the KO Propo 35542 aluminium gear set to reduce wear and keep your BSx servos tracking accurately during aggressive driving or long events.
Aluminium gears raise load tolerance while staying light, helping the servo hold position and improving repeatability under sustained strain.
When fitting the KO Propo 35542 set, clean bearings, use correct shims and fine tune the gear mesh to avoid binding and ensure long service life.
