The Futaba S9255 is a cyclic digital servo. It comes with heavy duty wiring that can handle higher current loads.
Ball bearing output shaft, metal gears, coreless motor. High torque.

(A conventional servo motor has a steel core armature wrapped with wire that spins inside magnets. In Coreless designs, the armature uses a thin wire mesh that forms a cup that spins around the outside of the magnet eliminating the heavy steel core. This design is much lighter resulting in smoother operation and
faster response time).
