228:1 Plastic Gearmotor, Offset Output
This 228:1 gearbox with brushed DC motor has a low-current motor and provides power and speed that is comparable to an RC servo at a fraction of the cost. At 6 V, it has a free-run speed of 45 RPM and a stall torque of approximately 100 oz-in. Though the product picture shows two gearmotors, this product is for a single motor.
