I would take that to say that any DC motor (non-KOP) can not be used at all, even if for use as a tachometer.

Thanks for the quote. The quote that I was referring to did not have the R44 rule.

I was wrong.

This is a strange ruling to me because, as a practical matter,
I really don't know how to distinquish between a motor used as a sensor to turn rotational velocity into a voltage and a tachometer.



The above "generator/tachometer" is legal, but a simple non-KOP Mabuchi is not. Seems strange...

But... the rule is the rule.
