The 2000 Series Dual Mode Servo is a feature-full standard size servo tailored for the robotics market! In the default mode the servo is able to rotate a whopping 280 degrees while retaining positioning feedback. Using the 3102 Series Dual Mode Servo Programmer (1-1) the servo can be transformed into a continuous rotation servo. With metal gears and over 200 oz-in of torque this servo is an excellent bang for the buck. Find it here -- https://www.servocity.com/servos
