[NSRCA-discussion] low profile JR servo?

[Ed Miller]

Is this an indication there is a problem with the 14mz ??? What are the 
symptoms ??

Hi Tony,
Does the throttle channel use the same encoder? If so, then it must be some 
sort of absolute encoder.

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?
