The Solarbotics GM17 Gear Motor is designed for low-voltage power-efficiency, but it isn't scared of generating a bit of torque. And the output shaft is shaped just like the GM2 - Gear Motor 2 Offset Shaft for full accessory compatibility! It's a small, slow, power-efficient but torquey motor, a bit bigger than its more powerful brethren.
