The Advantages of Digital Servos:
Digital servos offer extremely accurate and reliable centering, even in more economically priced servos.
Digital servos develop their power instantly. An analog servo develops its full power at its extreme movement. Digital servos develop their power as soon as they move, thus effectively making a digital servo stronger, even if its specifications are the same as a comparable analog servo.
Digital servos have extreme holding power. A digital servo stays in the position you command with all of its power, thus virtually eliminating the blow back found with analog servos.
Digital servos are precise. When used with a 2.4GHz digital radio, especially a fast radio such as Airtronics, digital servos more accurately translate and hold your command inputs from your transmitter. You will feel more connected to your model than when using analog servos.
Digital servos are compatible with the newest high frame rate receivers. In some cases, analog servos simply won't work with these new, high frame rate receivers.
