    What's up everyone. I have had the question asked, "what is the difference in Analog and Digital servos. Well, this video (well audio actually) will explain all of that and more. This is pretty much just a webcast, so there is no real need to 'watch' it. I got all of the information off of Futaba's website, and all credit goes to them. I hope this helps some of you out on your decision on whether or not to get a digital or an analog servo. Let me know what you think.

    Here is the PDF where I got the information

    Digital Servos are great, I use them, aswell as analogue servos. But when I use digital servos(power hungry monsters), the cheapie internal BEC in my ESC which is less than 2A will just not suffice! I ended upgrading my ESC with a Higher internal BEC 6A switching. With the analogue servos, when flying my 450 and 250's I really can't tell the difference between the performance of digital and analogue. May be on bigger helis it might be different??

    You can tell on a flybarless bird when it comes to centering. Most digitals will center perfectly every time. However, that is not the case with all of them. I have some solar servos here (DS929HV) that don't center worth a crap and I had to take them off.

    Yeah I forgot to mention about centering. Also for the tail I only use digital servos. For the cyclic you can get good and cheap analogue servos. It's great if you're on a budget. But you gotta shop around and know what servos to get. As for digital most servos have good centering some are not that good, but that's true less sub trim
