Motor Clarification
I read with great interest the Clean Horsepower article by Lee
Estingoy (Sept 2010 MA). I hope this is the first of a series of
these articles by Lee. It wetted my appetite, but left me with a lot
of questions.
There was a figure that
showed two screen shots
of magnetic flux on a
stator. The figure was
not discussed in the
article and I could not see any
differences between the two pictures.
I appreciate your including these “techie” and
historical articles along with the more general articles in
MA. Keep up the good work!

Yes, there was a bit of an editing error.
The one labeled 440 new lam 3 has slight changes to
the teeth on the stator that prevent the saturation
(magenta) shown in the other screen shot. This allows
for higher magnetic flux strength (? big words for a
philosophy grad, forgive me if I am mistaken here) throughout the stator and rotor. The rotor is
shown in these images, it is just inside the stator stack.
Hope this helps.

“Krazy” About Kaz
I would like to commend you and everyone else on the quality that MA has currently.
I have been an AMA member since the early 1980’s and used to love the magazine as a kid.
The 90’s and early 00’s were pretty low points in my opinion. The 2-3 years the magazine is
again something I look forward to getting in the mail.
The last issue was great. I love Classic Pattern aircraft and the article about Mr. Kazmirski
[“Kaz!” in the August 2010 issue] was perfect. I would like to see articles like that on not only the
old Pattern guys, but anyone that really promoted model aviation during its infant/toddler years.
While I am at it, I might as well request more build articles and reviews of Non-ARF
models.
Keep up the good work.

More Heroes, Please
We met last year when I attended the AMA pattern nats.
I recently read the August edition of MA and I would like to commend you and the AMA
staff for publishing the article on Ed Kazmirski. I have sent Duane Wilson an e-mail thanking
him for the article and associated research.
As a life long modeler dating back to the late 1950’s I would like to see more articles like
the Kaz article. I think that we owe the pioneers of the hobby the effort to document their
contributions and this could be done by continuing these types of articles.
I would like to suggest that this practice be continued. Additionally, I believe that this would
be a great way to enlighten/educate the people who are “new” to the hobby.
How about requesting and publishing articles on not only modeling pioneers but also those
that have “made a difference” in the hobby. How about articles on free flight guys like Reid
(who passed away on Monday) and Roger Simpson?
My father used to work for the US Air Force as a civil servant at a base in Laredo TX and I
remember flying with them when they were in the Air Force and came to town. I think MA
should solicit articles on people like Reid and Roger and other free flight guys who helped
make the hobby what it is today.
Don’t forget to include the control line guys. I believe that a long term schedule should be
developed to periodically publish an article on individuals who made a “significant”
contribution to RC (any category), control line and free flight. Articles on the Navy’s
involvement with the AMA in hosting the NATS would also be great.
I am quite sure a simple request in the magazine and on the MA website would bring a
number of articles on modelers who made a difference.
Just my thoughts. Thanks very much for accepting the article on Kaz from Duane.

Regarding Tom Derby’s comments in
the Aero Mail in the August 2010 issue of
Model Aviation:
Cool is an adjective that is used in
“describing qualities of the entity
denoted” according to Webster’s
dictionary. Cool: “very good, pleasing,
etc. excellent”. Quotes again from
Webster’s.
Cool is a slang word that probably
originates from the 1950s. I don’t need the
dictionary to understand what this word
means to me. It is a word that has been a
part of my generation a long time. I grew
up in the late 60’s/early 70’s. I know
extremely successful people that
commonly use this word all the time, albeit
usually in an informal situation more than
not. It creates a sort of common bond if
you will.
I think we are in a very cool hobby with
a lot of cool people.
This word does not belong solely to the
current younger generation as Tom
suggests. No offense kids. However, if you
manage to get the attention of the younger
generation by the use of the word cool in
your articles, all the better. We certainly
need more younger people getting involved
in this hobby.
I didn’t see cool mentioned once in your
August 2010 “The Inside Loop”. Too bad.
Freedom of speech Michael!!!
And Tom, lighten up, will ya? This is a
hobby, not a college English class.
The best part of this cool hobby is that
we can agree to disagree, lay down our pens
(computer key boards) and head out to the
field and have fun flying together!

The Family You Choose
I wanted to drop you a note, perhaps for
the “Aeromail” column.
There is and has been a lot of
conversation over the years about the
family of aeromodeling. This is a true
statement, but I wanted to relate a recent
incident in my own life.
We are all born into our own families
and by and large we love them, but we do
not always like them. There are always
issues. But the point is we are born into
these units. We have no choice.
By comparison we have the luxury of
choosing our friends. With any luck at all
we choose wisely.
I had the recent misfortune to experience
something that I am calling my adventures
in cardiology. On Friday morning of June
25, 2010, I had the misfortune of
experiencing a heart attack while on a
business trip in Detroit Michigan. It was
serious, the “big one” as some might say.
Not only was I not at home and away
from family, but my primary contact
people, my wife, was out of town on
business as well, with a cell phone that
crashed. So there was no way apparently to
contact her. Add to this the fact that the
Emergency Room staff was telling my work colleague to get my wife there as quickly
as possible. You can imagine the
circumstances.
Well since I had no way of contacting
my family, and my work colleagues were
already doing what they could, I had only
one recourse left to me. Because of my
participation in many different aspects of
modeling within the AMA, I have had the
good fortune to develop a modeling family
across the country. So I did the only thing
I could think of, I asked the ER staff to
contact the family that I picked out,
modelers who have become family.
I do not want to name names, but there
is a wonderful couple with whom I have
been friends for 15 years or more, living
just 15 minutes from the hospital, and I
asked the staff to contact them. To make a
long story short, in less than one hour, my
friends had more of my friends from
Wisconsin, Michigan, Tennessee, West
Virginia, and Pennsylvania, burning up the
phone lines trying to find my wife and
daughters.
Between all of these wonderful people
and my work colleagues, a phone chain of
my wife’s customers and colleagues, and
the satellite phone that comes with OnStar,
my wife was found and started on her way
to Michigan.
The first phone call that I received
came from my friend in Tennessee, to ask
if there was anything he could do to help.
Before the afternoon was half over my
Detroit friends were by the side of my bed
in Intensive Care to check on me. And by
6:00 o’clock that night my wife had made
the almost 9 hour drive from where she
was working to where I was recovering.
My point is this. I have through the
grace of a higher power and the magic of
the doctors in Detroit survived to fly more
airplanes. But the support of the family
that I got to pick, my modeling family, is
of a value that cannot be measured.
To ALL of you who helped in that
critical 12 hour period, thanks, I love you
too. MA
