[NSRCA-discussion] low profile JR servo?

[Tony Stillman]

Gordon:
I am just passing along the info as the comment was made.  I have the
encoders in stock, as Futaba made a change in the production of the 14MZ and
sent me new ones to change out when needed.

The futaba 14MZ flyer I have says "Gimbals with long-life potentiometer,
quad bearings, adjustable tension and detent."

In general encoders are not absolute positioning devices and you need to
define "home". Resolvers are absolute positioning devices but larger and
more costly.

The Futaba 14MZ uses shaft encoders on the sticks..

Hah, I didn't even think about the stick pots. Seems that would be the first
place they would try using shaft encoders.

 

Linear outputs from the servos would be great, also. Oh, wait a minute, that
was done 35 years ago with the KPS-11 servos. Nevermind....   :-)

Isn't technology great - $2000+ TX and $100+ servos with everything riding
on a 50 cent pot on each end!

When you say analog, I assume you are talking about the feedback loop? I
wonder how long it will be until we get shaft encoders in our servos. Or,
for that matter, the shaft encoder could be mounted to the control surface
itself.

Correct.  Well kind of.  Actually all of our servos are analog but you are
right, the super servos used the same principles as our modern "digital"
servos.

I was under the impression that the "Super Servos" were actually first
generation digital servos. Is that not correct?
