Solarbotics GM9 Gear Motor 3-12V (143:1)

The Solarbotics GM9 Gear Motor has a 143:1 gear ratio with a 90 degree output shaft and built in safety clutch.

This motor is similar to the Solarbotics GM8 Gear Motor but has a 90 degree shaft instead. The shaft is 7mm in diameter with two flattened sides and fits the Solarbotics Gear Motor Wheels perfectly.

This motor is about twice as fast as the Solarbotics GM3 Gear Motor yet still has a good amount of torque.
