💡 What does a differential planetary gear set do in an RC vehicle? A set of planetary gears spreads torque evenly through the differential so the RC car maintains traction on loose dirt or pavement. - Hardened steel versions handle the extra stress from brushless power systems during jumps and turns. - The compact design keeps the diff housing protected while delivering smooth power to the wheels. - Upgrading from plastic stock gears reduces the chance of stripped teeth during aggressive bashing sessions. - Proper fit ensures quiet operation and longer drivetrain life on 3S or 4S setups.
