When I run across articles like this "CAR:
Coupled Aileron Ruddered System for Radio Control" which appeared in the 1960
Annual issue of Air Trails magazine, dial cord, I am in awe of some people
for the genius, creativity, and willingness to do the hard work involved in advancing
the state of the art in a given field. Not surprisingly, Maynard Hill is the author
and progenitor of this - at the time - breakthrough method of combining aileron
and rudder control to enable at least some semblance of coordinated turns with radio
controlled model airplanes. Mr. Hill was a metallurgist in his day work at
Johns Hopkins' Applied Physics Laboratory. Distance and altitude records for R/C
models were among his many accomplishments. Looking at the complication of the electromechanical
coupled aileron-rudder control system...
Here is novel idea from well-known free flight
modeler Bill Hannan and hobby shop owner Russ Barrera. It appeared in a 1970 issue
of American Aircraft Modeler magazine. The pair converted an
transmitter case into a handy field box for use with free flight models. In
addition to adding a hinge and latch to the cover, the retractable antenna sports
a small wind sock for judging launch times and even a compass in place of the RF
power meter to note the direction of your model as it drifts off into the wild blue
yonder when the dethermalizer fails to trigger. Without the convenience of eBay,
finding an unused transmitter would have been a bit difficult for most free-flighters
back in the day...
"Rolls-Royce has submitted data to the Fédération
Aéronautique Internationale to verify claims for three new world records set by
the company's all-electric Spirit of Innovation aircraft. On 16 November 2021,
Spirit of Innovation is claimed to have reached a top speed of 555.9 km/h
(345.4 mph) over 3km, beating the existing record by 213.04 km/h (132 mph).
Rolls-Royce added that further runs at the UK Ministry of Defence’s Boscombe Down
experimental aircraft testing site saw the aircraft achieve 532.1 km/h (330 mph)
over 15km - 292.8 km/h (182 mph) faster than the previous record – and

1938 was still two decades away from when
America would launch its first Earth-orbiting satellite (Explorer 1, 1958)
and three decades from when man would first
walk on the moon (Apollo 11, 1969), yet work was well underway by enthusiastic
aerospace engineers, scientists, astronomers, project managers, and others to accomplish
those goals. While this Boys' Life article boasts of rockets attaining
speeds of 800 miles per hour, leaving Earth's gravitational pull for a trip to the
moon would require a escape velocity of 25,000 miles per hour. Telescopes powerful
enough to survey the moon's surface for determining a safe location for landing
were being readied with telescopes like constructed 200-inch Hale reflector, having
seen first light just nine years earlier. This type illustrated feature page was
common each month...
Airplanes Won't Make Much of a Dent in Air Travel for Decades to Come. Reason:
Batteries are nowhere near able to sustain wide-body airliners over flights measuring
in the thousands of kilometers. Exaggeration has become the default method for news
reporting, and the possibility of commercial electric flight has been no exception,
with repeated claims that these new planes will utterly change how we live. In 2017,
Boeing and JetBlue funded Zunum Aero, a U.S. company that promised nothing less
than transforming air travel with short-haul electric planes capable of carrying
12 people - and doing it by 2022. Two years later Boeing declined to continue funding
the project. At the Paris Air Show..."
If you're anything like me, you have an appreciation
for the older comic strips. Getting the message being conveyed sometimes requires
a knowledge of the events of the era, but for the most part the humor and/or satire
comes through even when you assume it relates to current events. WWI and WWII timeframe
comics, for instance, often alluded to the evils of Fascist governments overseas,
while today they may be likened to the deeds of our own government. These "Contest
Caper" comics from a 1955 edition of Air Trails magazine are timeless...

The December 2021 issue of the Academy of
Model Aeronautics (AMA)
Model Aviation magazine contained an article about the AMA Museum's effort
to post model aircraft related historical items on their website. I check to see
whether the two kits I donated in 2019 are there, and indeed they are. One is a
Parris-Dunn Little Bobby Helicopter Kite Kit and the other is a
D-4 Menasco Trainer Kit. Both were gifted to me by Mr. Steven Krick. Realizing
their historical significance, I contacted the AMA Museum and they gratefully accepted
the donation offer. I have not been to the AMA Museum since 1999, not long after
the initial building was commissioned, so it would be nice to make another trip
there and see the incredible collection on display now - especially the vintage
Not a lot of information is available about
the Roland D-2 "Wahlfisch" (Whale) on the WWW (World Wide Web). Wikipedia has a
entry for the C-II Wahlfisch, but nothing on the D-II. The C-II was also a biplane,
but its wing configuration had a lower and a shoulder location on the fuselage,
whereas this D-II has a lower wing and a high wing mounted on a centrally located
solid pylon. It seems that would be a real annoyance to the pilot with an obstruction
that hinders stereoscopic vision when looking straight ahead. The dual, wood stick
cabane strut arrangement must have been a lot better, although more difficult to
construct. The plans are nicely done by the author, D.A. Newell, but I do not
see a rib pattern...
Douglas Rolfe's sketch of this
C-II biplane is another example of his amazing ability not just to create a
drawing, but to depict the model's construction features in a manner helpful to
builders. That, coupled with the masterfully detailed and laid-out plans by Walter
Musciano and a brief history on the airplane along with its most famous pilot, Eduard
von Schleich, makes this an article you won't want to miss - especially if you are
a World War I historian. I have to wonder whether Eduard von Schleich's fellow
Flieger (aviators) referred to him as "verrückte Augen" ("crazy eyes")?...
It's hard to imagine back when only 14 years
had passed - to the month - since the Japanese surrendered to the U.S., that this
article with plans for a control line
Kawasaki Ki-61 Tony model
was written in the August 1959 edition of American Modeler magazine. The
Imperial Japanese Air Force, like the German Air Force (Luftwaffe), was made up
of highly skilled pilots and increasingly capable aircraft. The Japanese were a
notable more terrorizing enemy since many were willing to sacrifice their lives
in battle, whereas the Germans were more of the mindset of living to fight another
day. It is now 52 years hence since this article was written and very few of the
men who fought WWII - on all sides - are still alive to bear witness to the action.
As long as there are people who want to dominate the world, there will be wars...
If you like cutting and gluing wing ribs,
this scale control line model of the
Curtiss P6−E Hawk
is the job for you. Let me know after doing these 92 ribs for two wings if you still
feel the same way. These plans and building article appeared in the November 1957
issue of American Modeler magazine. Designed for a .19 to .29 engine, this
31" wingspan model will certainly present a challenge even to the experienced modeler.
Of course you need to be able to apply and finish the covering with a high level
of perfection in order to fully appreciate the amount of work put into building
it. Personally, I would hate to have to use opaque paint for a scale color scheme
in order to not have to hide the framework. Then, I would be afraid to ever fly
"China says it fired up the world's largest
single-segment solid-fuel rocket engine for the first time, at a ground testing
facility in the country's northwest on Tuesday. The rocket’s 3.5-metre (11.5-foot)
wide engine can generate 500 tonnes of thrust, according to the China Aerospace
Science and Technology Corporation (CASC). That is more than four times as powerful
as the liquid fuel engine on the Long March 5, the largest launch vehicle in China's
space programme at present. With its high mobility and near-instant launch capability,
solid-fuel rockets are mainly used to deliver missiles or on other military platforms.
Most solid rockets are relatively small, in part because, in most circumstances,

In this article appearing in the 1960 Annual
edition of Air Trails magazine, author Robert Angel introduces his "Uni−Flow"
concept for U-Control (aka control line, C/L) model airplanes. His method modifies
the standard wedge type metal fuel tank to operate on the same principle as an office
water cooler. By adding a strategically placed additional brass tubing vent, Mr. Angel
contends the pressure on the inside of the tank remains fairly constant as the vacuum
from the engine's carburetor draws fuel. This is preferred to pressurizing the fuel
tank via either a tap on the crankcase or off the muffler (which there were not
a lot of in 1960. Whether or not the Uni−Flow arrangement is any better than a standard
vent line or pressurization is still a matter of debate half a century later, as
can be seen in this StuntHanger.com forum thread. In fact, it seems the standard
C/L metal fuel tank is a form of uni−flow...

Propeller-driven air cars and boats were
popular in the 1950 and 1960s. They solved the problem of complicated and failure-prone
transmissions and had no traction issues regardless of terrain. Recall the James
Bond movies of the era that featured these vehicles regularly. As a teenager, I
built an air boat out of a block of styrofoam and a Cox .048 Babe Bee engine. A
rudder was controlled by my OS 3-channel RC system. It ran pretty well - nothing
to get excited about but it was my first radio-controlled model of any sort. This

U-Control, aka U/C, aka Control Line, aka C/L,
is still very popular today even with radio control available. It is a great model
of modeling for those of us with bad eyesight who have trouble with tracking airplanes
at a distance. With control line your model is never more than about 70 feet from
you and there is never a problem with knowing which direction the model is headed
and whether it is right-side-up or upside-down. In 1960 when this Annual issue of
Air Trails magazine was published, R/C was mostly a rich man's sport, or
at least an electronics man's sport. Free flight and control line dominate aeromodeling.
Monthly features like "U-Control Corner" ran in model aviation magazines of the
era, and offered many great tips...
I took the occasion of having to cover the
wingtips of my AAR-X1 electric control line model to make a short video of how I
cover a compound
surface (one that curves in two or three dimensions) with MonoKote. The only
"trick" involved is being daring enough to apply the amount of heat needed to exploit
MonoKote's extreme ability to shrink, while pulling on it to stretch it. By daring
I mean that it can take quite a bit of heat, even to the point of being dangerously
close to the melting point. It can also put the phalanges is peril while attempting
to stretch the MonoKote while heating it. In the case of these wingtips, there is
an open framework, but the method works equally well on solid compound surface.
I have smoothly covered carved sailplane nose blocks and curved wingtips using this

These half-dozen hand-dandy
building tips are as useful today as they were in they appeared in the 1960
Annual issue of Air Trails (Hobbies for Young Men) magazine. Readers submitted their
brilliant ideas to the editor, who then created drawings and brief descriptions.
I find myself doing many of the things that appear in this and of editions of the
vintage modeling magazines - of course that might have something to do with my being
"vintage" at this point in life (born in 1958). Back when these items were published,
availability of most tools and material was nowhere near as abundant as today. It's
hard to imagine anyone nowadays making a drill bit out of a nail, but in a pinch
you never know...
Depending on the phase of the moon, the prevailing
wind, stock market activity, or the color socks I have on, my interest in airplane
activities alternate between radio control, free flight, control line, static display,
or any other aspects of modeling. Over the years, I have designed and built probably
four or five different field boxes to accommodate the mood du jour. Each was sold
before moving on to the next design iteration. Finally, I decided that rather than
keeping on making new field boxes, it would make more sense to design a one-size-fits-all
version. The Chameleon Field Box™,
as I have dubbed it, comes pretty close to achieving that goal. The design work
was done on Autodesk's AutoSketch release 6. I still have the file, but upon opening
it again after many years, I discovered that I never did put in all the detail for

If you ever had any doubt whether Bill Winter
was one of the model airplane hobby's earliest and most prolific contributors, check
out this article that appeared in the January 1955 edition of Popular Electronics
magazine (only the third issue since its inception). Radio control systems were
just beginning to be commercialized and priced at a point where a lot of the public
could afford it. Quirks and high unreliability that plagued early systems had become
less of an issue so that airplane and power plant design efforts could take priority
with aeromodelers. In this article, Bill addresses setting proper
wing incidence and engine
thrust angles for good, repeatable, stable flight...

Were you or anyone you know - father, brother,
son, uncle, nephew, grandfather, friend, enemy - attend the
1974 National Miniature Aircraft Championships (NATS) at Lake Charles, Louisiana?
Why that location was chosen for a mid-summer event is beyond me, but the NATS were
held there a few times. John Clemens was Academy of Model Aeronautics (AMA) president
at the time. I had just become aware of the AMA a few years earlier at the ripe
old age of about 13. After 63 years on Earth I still have never experienced a NATS
- or the Toledo Show for that matter (which, alas, is no more). I have managed to
visit the AMA Headquarters in Muncie, Indiana, twice, though, but that was nearly
two decades ago shortly after they opened. ...but I digress. Here is a thorough
accounting of the goings-on at the 1974 AMA NATS as presented in the November 1974
issue of American Aircraft Modeler magazine...
Since there is a lot of wisdom conferred
each month upon the model aircraft magazine reading public, I thought it would be
of service to scan, OCR (so you can search the text), and post some of the articles
from vintage American Aircraft Modeler magazines. This first is the "Walt Mooney on Free Flight,"
from the January 1974 issue. One item is how a flying club near the Miramar Naval
Air Station (of Top Gun fame) lost its site because someone (a non-member) flew
an R/C glider at high altitude during a full-size training exercise, thereby disturbing
the program. Eventually, all kinds of aeromodeling will be covered including free
flight, control line, and radio control. Stay tuned for more to come...

the Tortoise has passed the distance markers. See the credits on page 37 in the
actual magazine. The Tortoise got its name by virtue of the craft having landed
near a turtle on the runway. It was a long day, with everyone being sunburned by
the end of it. We were all members of the Prince Georges Radio Control Club (PGRC)...

but frankly I'd be more interested in landing safely at that point. The pilot flies
it with a throttle lever on the left, a joystick on the right, and a pair of pedals,

While the originality and craftsmanship exhibited
model car designs entered in this contest sponsored by Fisher Body Craftsman's
Guild is unassailable, I find myself being grateful that most of them never hit
the car lot showrooms (although some designs are not too far off of what has been
produced here and in Europe). The date of this Air Trails - Hobbies for Young
Men magazine article was 1954 and imaginations ran wild with concept car configurations,
and while just about anything goes in such competitions, some were downright, dare
I say it?, ugly. Of course a look at some of today's concept cars register the same
emotions, so I suppose the old adage about the more things change, the more things
stay the same holds true here. Scholarships handed out...
