Motors & Servos Look Alike Check the labels carefully! Only old motors have three wires. J. M. Gabrielse

Servos • servos turn to a specific angle (0°- 120°) – position attachments exactly – perfect for claws • servos only turn part way around (120°) – can’t make gears or wheels spin around J. M. Gabrielse

Motors make attached axles spin at a set speed. Perfect for wheels and gears. Motors can’t turn to an exact position. J. M. Gabrielse

Standard Motors (269) • standard motors • light weight • batteries last longer High Strength Motors (393) • give 30% more torque or 30% more speed (if you change the internal gears) • heavy • reduce battery life J. M. Gabrielse
