any merit in running dual battery packs ?

[Dwayne & Nancy]

When I worked at TI from 1965 to 1979 I had a friend in the research
department who told me that he had invented the pulse code method servo
position for TI but they did not want to patent it.  When the Digitrio
schematics and description were published in RCM he said he had already
been there and done that.  His name was Cliff Penn.  Dwayne

Hi Bill,
I dunno, but I'm thinking it was in the late sixties. When and to whom
did he sell the company? Which flavor proportional was the radio you
spoke of? I assume it was an analog of some sort. You know, when you
look at the architectures used by the designers at the bleeding edge,
back then, to get proportional control, it was awfully inventive. Even
in this all-digital age, there may be something useful there.

Dean:
Was all this after Dunham sold out Orbit to the Japanese?  I, (along
with Chuck Boyer) used to be sponsored by Bob, but a couple of years
after going with United Airlines, (1964) I kind of left myself out of
the loop.  In fact, our entire group started off in different
directions. (Motorcycles, private flying, race boats, etc. but that's a
different time and story.)
I had occasion to fly the first transistorized true proportional that I
knew of  ~1958 or so; Zel Ritchie asked me to evaluate it for him.  I
flew it a few times and told myself:  "this is the way it should be
done."  Of course, I told him also!<G>

I can still picture the old Orbit ad in my head, the Pattern plane used
as a test case was a Super Duck. I think it was the successor to the
Cold Duck, which was presented as a construction article in RCM a
million years ago.

Dean,
 
I did not know Orbit did that. I know Proline did. I loved those
Competition single-stick radios.

Hi Ron,
Nickel tends to fail short. That's actually good. Once upon a time,
Orbit sold its packs with diodes across each cell to protect against
failed-open cells.
