Digital servos?
I just ordered the Futaba 9C with s3151 digital servos. I did a ton of research on radios, but NONE on servos. All the "science" behind all the is overwhelming when all I really want to do is fly. I was hoping to use the servos in my glow Cessna, for which I will have to buy one more servo since the package only comes with 4. Although, I just noticed that I might need 2 aileron servos, so these might not work for that. What is the advantage, or disadvantage of digital servos? Will these work for my Cessna? Since I need one more, and the digital are a bit pricey, does it have to be digital?
Tell ya, I don't know what I would do without this site. You guys are great!

Theres a link on there to a PDF that discusses them. They will be fine unless your flying an unusually large or small plane. The 3151s are the bottom of the barrel as far as digitals are concerned. In your case if you are putting together a 40 or 60 sized plane use the ones that come with the radio, buy a standard servo and use it for throttle where you will have no advantage with a digital servo.

So I can mix digital and Analog on the same receiver? I'm thinking these servos might not fit in the wing, and it would be cheaper if I didn't get digital servos for that.

RE: Digital servos?
I'm a little confused over the ratings on the 3151. Tower shows torque and speed for both 4.8 and 6.0 volts, but the article you referenced and the manual that came with my 9C Super only shows data for 4.8 volts, which I take to mean these cannot safely run on 6 volts (although why anyone would design a new servo that would not work on 6 volts is beyond me!) So, can the 3151 digitals run on 6 volts, safely?
