...The biggest benefit from digital servos is not the torque, or speed, but the fact that they develop their maximum torque at only 2 degrees off center from neutral, whereas a non-digital doesn't reach maximum torque output until around 18 degrees.
Good to know! I've pretty much convinced myself to use nothing but coreless digitals in anything 65" and up. Expensive servos, yes, but cheap insurance if you ask me.

I am starting to think that I have too much travel in the surfaces for what I need, and I am wasting mechanical advantage, as well as servo resolution at the expense of high throw rates that I can't use.
If you don't need the travel, well, you know. Seems like on my last few planes I wanted ALL the elevator throw and rudder throw I could get for 3D flying. However that may change with the maiden of my 31% CA Extra / ZDZ 80 this weekend (hopefully)...the rudder is
ENORMOUS.

So long as you're not reducing the throw via ATV's you doing it right. If you're running your ATV's reduced you're giving up servo resolution. Set your ATV's to maximum (I actually set it just short of maximum to account for centering adjustments.. about 140%), and then adjust throw mechanically to get what you want. THAT'S maximum resolution and mechanical advantage.
Good idea on the 140%. For sake of argument, say I'm using 140% ATV on the ailerons...now I'm adding snap spoilerons...now for some weird reason I'm using full spoilerons and full ailerons...what will happen to the servo?
