RC Servos
We carry a wide variety of servos, from ultra-high-torque monster servos with up to 1600 oz-in of torque, to sub-micro servos weighing less than 4 g (0.14 oz), to continuous rotation servos that are great actuators for beginner robotics projects, and all of the RC hobby servos below are compatible with our servo controllers. Whatever your application, we probably have a servo for it!
Check out our RC servo comparison table for detailed specifications of all our RC servos; this dynamically sortable table can help you find the servo that is right for your particular application. A more basic comparison table is available below.

Subcategories
Continuous rotation servos are standard hobby RC servos that have been modified to offer open-loop speed control instead of closed-loop position control, making them great actuators for beginner robotics projects.
These specially modified servos provide access to the feedback potentiometer through a fourth (green) wire, allowing you to directly measure the position of the output. Determine when the servo has reached a target, detect when the output is blocked, or implement higher-level closed-loop position control.
