Billionaire’s Supersonic Private-Jet Plan Hits Engine Snag
"Aerion Corp., backed by Texas billionaire Robert Bass, has hit a
snag in one of the most crucial milestones toward building the first business jet able to fly faster
than the speed of sound. The selection of an engine supplier for the plane, which Bass once said would
occur in the first half of this year, is now expected to come in 2017, said Jeff Miller, a spokesman
for the Reno, Nevada-based company. Aerion is 'making good progress,' Miller said Tuesday in an interview
Battery Problems Spoiling Your R/C Fun?
As with most electrical and electronic equipment, performance
increases have come often and significantly in the six decades wince the article was written. In 1957,
battery technology was
still crude by today's standards, but much advancement had been accomplished during the war years of
WWII and Korea for the sake of field portable communications gear. Chemistry and packaging improved
to where if the user was knowledgeable and applied certain precautions, a high degree of reliability
could be garnered from various cell types. Having the right battery for the task at hand was
"Spirit of Saint Louis" Ryan N-Y-P, 5-View
Walter M. Jefferies, Jr. inked another masterpiece for the June
1957 issue of American Modeler - the
Spirit of St. Louis.
This 5-view drawing reveals many details of airframe components, fittings, and rigging. Much more detailed
plans are available from sources like the AMA Plans Service if you are thinking about building a version of "Lucky Lindy's"
famous aeroplane. Interestingly, the August 2016 issue of the Smithsonian's Air & Space
magazine reported on a pair of pliers discovered under the floorboard
Model Boat Record Breakers, July 1957 American Modeler
When most people think about control line
(CL) models, airplanes are what comes to mind. However, prior to the advent
of miniature, reliable radio control (RC) systems,
model boats and model cars also ran
on control lines. Most of the time they went in circles, just like model airplanes do; however, some
hobbyists stretched out long sections of straight line in order to get maximum speeds from their craft.
Unlike with model airplanes where an operator in the center of the circle exerted control of the elevator
(and sometimes throttle), the boats and cars generally ran
Accelerating the Future of Aircraft with Electricity - Airbus E-Fan
"It seems as though it's
becoming a daily occurrence for companies to launch initiatives to create the greenest technologies.
Airbus has decided to join the race and create aircraft which produce zero CO2 emissions. The plane
of choice is the Airbus E-Fan, and its engines are powered entirely by electricity. Their goal is to
create 'short-range commercial aircraft.' The E-Fan first earned its name
How to Woo a Gal with Models
Even after decades of trying to convince
girls and women that they should
do everything boys and men do, somehow there is not a 1:1 relationship with activities. Hmmmm, maybe
there really is an innate difference between males and females. Well, since gals and women couldn't
be convinced to do all the guy things, society is now trying to get guys to do gal things. Try as they
might, though, little Johnnie still doesn't care too much about playing with doll babies. I suppose
that old adage about being able to lead a horse to water but not being able to make him drink it applies
to humans ...
Sheer Nonsense? No, Sir!
Mr. Richard Von Berg wrote this great introduction to the
basics of shear
forces within an airplane wing. It appeared in a 1957 issue of American Modeler, but the principles
have not changed since then. If you are familiar with the terms wing loading, shear, compression, tension,
and bending moment but are not quite sure exactly what they mean, this short piece is exactly what you

Greensboro Martial Arts Academy (GMAA) Diorama
Sometime around the year 2000, while we were living in Fairfield,
Ohio, our daughter, Sally, made a diorama of a Tae Kwon Do martial arts dojo that was inspired by the
school she was attending at the time. Unbeknownst to Sally, Melanie and I had kept the diorama in a
cardboard box for lo these many years. We decided to make a nice wood and Plexiglas display case for
it and present it to her for her birthday. The case is made from some scrap walnut given to me by a
friend. Korean, Chinese, and Japanese versions of "Greensboro Martial Arts Academy"

Swinging Tabletop for Notebook Computer
around 1996, I slipped on an icy sidewalk in Colorado Springs, landing on my back and whacking
my head on the concrete. Ever since then, I have had recurring nerve-related issues in my right arm
and hand due to cartilage damage in the C4-C5 cervical vertebrae region. It is strange to experience
a pain that seems to originate in my fingers, upper arm... The design is neither elegant nor sophisticated;
it's even a little embarrassing. Why embarrassing, you might ask? If you look at the labeled assembly
photo, you will see that the bottom and top mounting components are
Supermoon of November 14, 2016
Here is my contribution to the science of astronomy for the
recording of the November 14, 2016
'supermoon.' The photograph was actually taken at 8:45 pm EST, which technically was a few hours
ahead of the formal full moon (8:52 am). Notice on the eastern edge you can see the outline of craters.
Full moon photos are typically the least impressive because with the sun shining nearly straight down
on the surface, there are no shadows cast by the ridges of the craters. Contrast is also at a minimum
because the image is so bright - like trying to see something when the sun is staring you in the face.
My photographic equipment was bare-bones minimal with
TU Delft's Newest Tailsitter Drone Designed for Outback Delivery
designs are usually a choice between flexibility and endurance. You can either go with a multirotor
that'll let you hover and make pinpoint landings, or you can go with a flying wing, which can handle
bigger payloads and longer ranges.
Delft University of Technology in the Netherlands has a history of managing to make
successful drones that combine the best features of VTOL and fixed-wing flight. With their latest aircraft,
they’re going old-school, with

China to Build World's Biggest Space Plane by 2020
"This year China has been firmly establishing its place in the
space race, by unveiling the world's largest radio telescope, launching a space lab in preparation for
a space station and unveiling plans to send a mission to Mars. Now it seems the country also has its
eyes on commercial spaceflight. Designs of a new
space plane, which could fly up to 20 passengers to the edge of space
each day, have been revealed
Making a Radio-Controlled Model "Saratoga"
Even though I am appreciative of and nostalgic for the memories
of 'old' ways and means, I definitely am glad to have modern technology. Take a look at the bulk of
that simple function selector switch which was part of the
for the Sarasota model ship. The 160-meter CW ham radio band was chosen for communications. Even a simple
1/4-wave antenna is 40 meters long (~131 feet), requiring the wire to be strung up in a tree and then
a 'ground' conductor to be submersed in the water (see Fig. 1f). In 1936, there were no unlicensed radio
The National Championships, November 1950 Air Trails
Model airplane flyers have always been a rugged bunch that
can only be dissuaded from flying by the roughest of weather. This is particularly true at contests,
where those who dared to risk their aircraft's well-being to the elements competed against a smaller
field of contenders. The story behind this particular
in 1950 is interesting in that the U.S. Navy hosted the events on active bases, and the breakout of
the Korean War occurring mere months before the scheduled date nearly caused a cancellation. Per the
article, "By July 25th every Navy base in the country except Dallas NAS had been closed to the public."

Air Progress: The Search for Speed
Douglas Rolphe ran a series of "Air Progress" and "Auto Progress"
features similar to this one where he included line drawings and short factoids on each vehicle, with
a timescale of sorts that shows progression in the state of the art. "The Search for Speed"
has, as you might guess early model aircraft that were designed for racing and/or setting speed records.
Many were one-of-a-kind and might make excellent subjects for scale builds in any of the competition
categories - radio control, control line, free flight, or even static display
