Yes, it is an on-going question about any subject. How, when, where did it start
? Who did it ? What was the idea that brought it ? It is like a Sherlock Holmes
story, where you need to put back the pieces of the puzzle, to get the final
So, I was curious on the matter, but since I did not have a lot of
information on it, I decided to create
a thread on the Ezone as I was sure lot's of valuable data would come out
quickly and it did. Then, decided to share the data here, in
order for everyone to get access to it easily.

Here is the .pdf file
of the cover and each page containing any portion of the article called
"Cordless Electric Flight Motors" by Bob Meuser from the July 1973 issue of
American Aircraft Modeler. The magazine was, at that time, the official
publication of the Academy of Model Aeronautics and came as one of the
membership benefits, though the magazine was also a separate commercial entity
rather than being published by the AMA as today's Model Aviation magazine is.
The scans are from my
copy of the magazine, received in the mail as part of my AMA membership. The
magazine cover and the color overleaf page for the article are scanned in color,
the rest in black and white
as I got poorer results using greyscale. But that does render some of the black
and white photos poorly.
In July of 1973 I was between my junior and senior years in high school, and
even then was interested in electric flight. It is odd that I had completely
forgotten about this article until it came up in that Ezone thread.
Mr. Meuser, who was the free flight columnist in AAM at the time and well into
the days of the reborn Model Aviation in the late 1970s and early 1980s, refers
to future installments looking at batteries and different types of models - to
complement this article which was mainly about the motors themselves. This makes
me want to dig through more of my old AAMs to see what other gems may be in
I also enjoy looking at the old advertisements.
One thing I just noticed: the specs for the original Astro Ferrite 25 add
up to about 245W input power in a motor that, alone, weighed nearly one lb.
(over 400g). Nowadays one can get that kind of power from the
likes of an AXi 2814 with room to spare...... amazing.
