Tripp...
Here's the "short" version: Digital Servos typically have better centering, much
better "repeatability" (ability to return to a specific point), a much narrower
deadband, greater holding power, greater initial start-up torque, and higher frame
rates than their analog cousins. Additionally, there are now programmers available for
digital servos that allow you to fine-tune many of the servo parameters such as
transit speed, end=points, and in some cases a "failsafe" position. As an example, the
HS5125MG specs are stated as (all values at 4.8V):
0.17sec 60 deg. transit [IMO - not exceptional speed but not bad either]
41.66in/oz torque [IMO - relatively powerful]
In speaking with Mike, one of Hitec's tech's, he stated that the "holding power" (a
spec not usually considered when comparing servos) is 100in/oz...That's very
respectable by anyone's standards! I'm not saying that the HS5125MG is THE wing servo
(you know that I sell them so may appear "biased" <G>)...It's too new to tell yet.
However, based on my personal experience using Hitec Digitals in the "torture chamber"
of my R/C Heli's, it should perform as well as its other digital brothers and, if it
does, it will prove to be a good servo. Time will tell...
The downside...Is they are typically higher in cost and they usually draw a little
more power.
Hope that answers your question...

Something I've been wondering for a while now...What's the difference between analog
and digital servo's and why would I want to spend the money on digital?

Subject: [RCSE] HiTech Servo's
The two best thing I saw at the Toledo Show were the smiling face of Jim
Deck at the LSF booth and the new HiTech digital wing servo. The new HiTech
HS5125MG digital servo's were available in limited supply. I purchased two
of them from Maxx Products. I also saw a non-digital version of the same
servo in the HiTech booth and was told that these should be available by the
end of the month with an approximate street price of $50.00. The non-digital
version is the HS125MG.
