This is a High Torque, High Speed Digital Mini Servo from Futaba.

FEATURES: Coreless motor: conventional servo motors have a steel core armature
            wrapped with wire that spins inside magnets. In a coreless design
            the armature uses a wire mesh that forms a cup that spins around
            the outside of a magnet. This arrangement is much lighter, which
            results in smoother operation and faster response time.
          Nylon Gears
          Can be used with 1/12 or 1/18 scale vehicles and electric helicopters
