While older, larger white clutch gears existed, this compact 16-tooth version allowed designers to integrate a safety mechanism into much smaller and more intricate designs. It quickly became a staple in almost every motorized flagship set, providing an elegant and compact solution to the age-old problem of motor burnout.\u003c\/p\u003e  \u003cp\u003e\u003cstrong\u003eDon't risk your valuable motors.
