Digital servo motors offer two advantages over conventional analog servo motors namely speed and holding power. The microprocessor that controls a digital servo motors position is six times faster than the analog one. Digital servo motors offer higher resolution that reduces dead band and thereby provides ultimate control. Digital servo motors also produce constant torque and have considerably more holding power. One disadvantage (who cares) of digital servo motors is that they consume more battery power, so when used in a rc nitro car one must use a high capacity NiMH pack.
