[NSRCA-discussion] low profile JR servo?

[Gordon Anderson]

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?
