Even during the busiest times of my life I have endeavored to maintain some
form of model building activity. This site has been created to help me chronicle
my journey through a lifelong involvement in model aviation, which
all began in Mayo, MD

For as much as I desperately wanted a radio
control system when I was a kid, I never bought an R/C system until I was around
15 years old, when a used 3-channel OS digital proportional system became available from
a man that lived a couple blocks away. Even the "cheap" $100 rudder-only escapement
models were out of reach on my paltry income from a paper route. So, it wasn't until
a couple years ago, at age 50, that I finally purchased an escapement from someone
on eBay, just to see one up close. Some of the airplane kits I had, like the Carl
Goldberg 1/2A Skylane, showed an escapement installation on the plans, with the
rubber band engine and a rather large receiver constructed of discrete transistors
and large tuning coils.
While looking through the July 1957 issue
of American Modeler, I happened across an advertisement for the very escapement
that I now own. There are no markings on the device - not a manufacturer name or
model number. It turns out the escapement is "The Single," from Bonner Specialties.
It is a self-neutralizing 4-arm escapement which provides stronger action to operate
throttle, other auxiliary controls. Weight: 0.6 ounces. Price: $5.95.
I built a mock-up of an escapement installation for controlling the rudder in
a single-channel radio controlled airplane, and then made a video to show how it
works (see below photos).
You can use the U.S. Bureau of Labor Statistics'
inflation calculator to see
that $5.95 is $46.23 in year 2010 dollars.
