As with so many other aspects of
technical application, the state of the art of
rubber motors has advanced significantly
since the writing of this article - not that the information contained herein is
anywhere near obsolete (except trying to find Pirelli rubber). Rubber motor
braiding techniques, lubricants, the rubber length, width, thickness, modulus,
composition, has all been studied and characterized to the nth degree so most of
the guesswork is gone as far as the actual motor performance is concerned. Still
all the other variables in the airframe and propeller system (prop, bearing,
gearing)...
"Unknown
drone activity forced one of the U.S.'s most critical military installations to
shut down for several hours late Friday evening and Saturday morning, officials
confirmed. The incident prompted heightened security measures and temporarily
halted operations at Wright-Patterson Air Force Base in Ohio. Home to the
88th Air Base Wing, Wright-Patterson is one of the largest and most
strategically important bases in the U.S., tasked with advanced research,
intelligence, and operations. Unauthorized drone activity in military airspace

Lifeguard duty is the latest application
for radio-control systems and the combination of modern high-powered electric motors
and Li-Ion batteries. An Arizona-based company called Hydronalix has created a robotic
flotation device to deploy to reach swimmers in distress when a lifeguard can't
get there soon enough. The robot is called EMILY, which is an acronym for
Emergency Integrated Life-saving
Lanyard. EMILY weighs 25 pounds, can go up to 25 miles per hour and can be used
as a flotation device for up to six people. Its batteries will run the device for
about 15-20 minutes...
The 1939 Thompson Trophy Air Races, held
in Cleveland, Ohio, was the final show for that series until after World War II.
Roscoe Turner was there in his Meteor LTR-14 racer. He had won top spot the
year before with a speed of 283 mph, and in 1939 at 282 mph. In a unique
turn in aviation career tacks, Turner conjured up a scheme where, based on equally
unique circumstances largely of his own design, adopted a lion as a mascot to sell
his services as a corporate products promoter. His first big success was with Gilmore
Oil, after which the lion was named. "Gilmore" flew around the country with Mr. Turner...

The
Cessna 336 and 337 Skymaster
hold a unique place in aviation history as distinctive twin-engine aircraft with
a push-pull configuration. Their design addressed the challenges of asymmetric thrust
inherent in traditional twin-engine aircraft, with both engines mounted along the
centerline - one in the nose as a tractor and the other in the tail as a pusher.
Development began in the late 1950s, led by Cessna engineers under the leadership
of company president Dwane Wallace. By February 1961, the first prototype of the
Cessna 336 took to the skies, featuring a fixed landing gear design. Production
of the 336 began in 1963, but it faced limitations in market success due to its
performance constraints and non-retractable gear...
Don Berliner wrote a historical article about
the Bellanca 28-70
Irish Swoop racer for the August 1972 edition of American Aircraft Modeler
magazine. Bjorn Karlstrom provided one of his masterpiece 4-view illustrations.
I scanned, OCRed, and posted the contents for your convenience. The Academy of Model
Aeronautics still provides full-size drawings and plans for most of the airplanes
featured over the years. "The Bellanca 28-70 was a long-range air racer designed
for James Fitzmaurice Irish pioneer aviator, who christened it Irish Swoop. Although
it was built in time for the 1934 MacRobertson Race from England to Australia, it
was never destined to be a competitive long-distance racer but it was ultimately
reborn..."
"On the shores of Lake Geneva in Switzerland,
École Polytechnique Fédérale de Lausanne is home to many roboticists. It's also
home to many birds, which spend the majority of their time doing bird things. Flying
is a lot of work, and many birds have figured out that they can instead just walk
around on the ground, where all the food tends to be, and not tire themselves out
by having to get airborne over and over again. 'Whenever I encountered crows on
the EPFL campus, I would observe how they walked, hopped over or jumped on obstacles,
and jumped for take-offs,' says Won Dong Shin, a doctoral student. 'What I consistently
observed was that they always jumped to initiate flight, even in situations where
they could have used only their wings.' Shin is author on a paper published today
in Nature that explores both why
birds jump to take off, and how that can be beneficially applied..."
Up until the United States of America officially
entered what became known as World War II (on December 7, 1941, following the
Japanese attack on Pearl Harbor), what we now call World War I was referred
to only as "The War." Recall that is was dubbed by H.G. Wells to be "The War
to End All Wars." It did not. This "Snapshots of the War" piece in the March
1937 issue of Flying Aces magazine features what air power looked like
in the early days of World War II. Interestingly, the "cocarde" (aka "cockade")
referred to in the wrecked De Havilland D.H.-4 was, according to most contemporary
sources, a term used to describe similar insignia worn on military head dresses
and jackets. Insignia painted on military equipment was called a "roundel." There
is a very nice photo of a Clerget rotary engine as it was mounted in the Sopwith
Camel, along with the twin Vickers machine guns mounted to fire through the propeller

The role of the
flight engineer is
one of the most significant yet increasingly historical professions in the history
of aviation. Introduced during an era when aircraft systems grew increasingly complex,
the position of flight engineer bridged the gap between pilots and the intricate
mechanical and electrical systems of larger, multi-engine aircraft. The history
of the flight engineer position is closely tied to the evolution of aviation technology,
airline operations, and the military's increasing reliance on heavy aircraft during
and after World War II. The position of flight engineer first emerged in the 1930s
with the advent of multi-engine commercial aircraft such as the Boeing 314 Clipper
and the Douglas DC-4. These aircraft required a dedicated crew member who was responsible
for monitoring and managing the various systems, including engines, fuel, hydraulics,
pressurization, and electrical systems...
As a lifelong admirer of Charles Schulz's
Peanuts comic strip, I occasionally buy a collectible item like a Snoopy music box
that plays "It's a Long Way to Tipperary," a plastic Schroeder and piano figurine,
a Charlie Brown Skediddler, or a Snoopy astronaut from the Apollo era. This time
I bought the edition of TV Guide that announced the first showing of the "A Charlie Brown Christmas"
cartoon. Also in this edition is the announcement of plans to preempt regular programming
to televise the launch of the Gemini VII spacecraft, which carried astronauts
Frank Borman and James A. Lovell. It launched right on time at 7:30 pm on December
4th, 1965. "As his millions of fans long since have discovered, under that inept,
ineffectual, bumbling exterior of Charlie Brown's there beats a heart as soft and
sweet as a marshmallow. In the sequence on these pages, drawn exclusively for TV

meaning of Christmas...
I've been using X-acto tools since my teenage
years the early 1970s. Before that, my razor knife blades were either the single-edge
hardware store type or double-edge blades copped from my father's safety razor (those
were truly dangerous, even with one edge taped). Half a century later, I now have
a selection of many flavors of X-actor blades and handles. As the chart above shows,
there seems to be an X-acto blade for every purpose. I often wondered what they
were all meant for, until I found this
X-acto Blade Usage Chart
from the company. Like most people, by far my most often used blade is the trusty
#11. I've been through hundreds of them. X-acto also makes a wide variety of specially
shaped carving blades, including vees, cups, circles (routers)...
Most people these days are probably now
aware of an aeronautical profession that up until around the early 1980s was a vital
part of aviation - the
flight
engineer. This 1950s article in Air Trails magazine highlights what
was at the time a very prestigious and sought-after position for people wanting
professional level careers in both commercial and military aviation. Since the 1930s,
aircraft were rapidly growing larger and more complex. Most had two to four engines,
retracting landing gear, pressurized cabins, autopilots, electronic and celestial
navigation, long distance routes, and increasingly crowded airways. All that plus
en route and destination airport weather, and even ground traffic clutter at
airports...
This is part two of a series from the March
1957 issue of American Modeler magazine that briefly introduces a dozen
winning free flight models and comments from their designers. Current day modelers
who like to fly the vintage (old timer) airplanes might pick up a useful tip from
the masters of the golden age of free flight. Materials have not changed a lot since
then, other than maybe the use of carbon fiber in the airframe, and no doubt engine
technology has gotten better, but the fundamentals of trimming for the powered and
glide portions of free flight pretty much remain the same...
Anyone
who watched the
WKRP in Cincinnati TV sitcom back in the 1970s has to remember what was one
of the funniest episodes ever. Here is the 4 minutes that made Prime Time history.
In this Thanksgiving episode, station owner Arthur Carlson decided he would surprise
the community with good deed - that doubled as a promotional stunt for his radio
station - by dropping turkeys from a helicopter for lucky shoppers at the local
shopping mall. Watch the disaster unfold as Les Nessman reports live, and then see
Carlson's final comment that is still used or alluded to in many comic routines.

"A team of students at the University of
Southern California has officially set a
new record for the highest amateur space launch - and they've set the bar very,
very high for anyone who tries to beat it. The rocket, Aftershock II, reached a
height of about 470,000 feet (about 90 miles), passing the existing record for highest
amateur space flight by about 80,000 feet. The launch The team's successful launch
took place on October 20, though it took roughly a month for the student team to
verify the data via a report this month. That data showed that the amateur rocket
traveled roughly five-and-a-half times the speed of sound during the launch. To
perform the test, students from the USC Rocket Propulsion Lab traveled to the Black
Rock Desert, since the playas and dry lake beds there proved suitable..."
This brief piece from the October 1950 issue
of Air Trails magazine was a springboard into articles on
control line models for beginners. The Peppy Trainer, for example, is 28" wingspan,
flat−bottom airfoil control line model with a solid balsa fuselage and tail surfaces.
It used a .09 engine - which would typically be easier to adjust and keep running
than a standard .049 engine. That article also recommends more than a dozen other
good trainer models to server both the rank control line beginner and someone just
getting into control line aerobatics. Many have built-up fuselages, which the experts
claim is best for high precision maneuvers since the rigidity of the 3-dimensional
structure minimizes twisting, keeping the alignment between the wing and horizontal
stabilizer consistent. There are low-wing, mid-wing, and high-wing configurations,
both scale-like and non-scale...

1943, in the midst of World War II,
was about the beginning of the time when all the
fantastic predictions of flying cars, video phones, domestic robots, two-day
work weeks, meals in pill form, self-driving lawn mowers, self-driving cars, moon
and planet habitats, and other creations were being pitched by technical magazines
like Popular Mechanics, Popular Science, Science and Mechanics,
Mechanix Illustrated, and others. Even the "women's" mags were full of
promises of automated everything to make housework simpler. While many of the fundamental
inventions has since been created, only a few have evolved to full maturity as envisioned.

Here is a very simple technique for creating
and applying custom lettering
- or even complex graphics - using Monokote covering. It makes cutting out and
positioning the individual pieces easy on flat surfaces or surfaces with a simple
curve or bend. Complex surfaces like cowls and wheel pants can be more challenging,
but at least the shapes can be created this way. Use any word processor or graphics
program to create the exact size and text and/or graphic shapes, including spacing
and alignment, italics, font face, etc., that you want on your printer. Print it
out on regular printer paper (20# works fine). Tape the paper onto the Monokote
and cut out each character with an x-Acto...
This
Midwest Products Sharpie Schooner is
one of two static display models that I built for my dearest, Melanie (the other
being a Midwest Products Muscongus Bay Lobster Smack). She actually bought them
to build herself, but decided to let me build them instead. I used my woodworking,
metalworking, and painting skills for the structure and accessories, and she used
her sewing skills to make the sails. Applying all those tuft strings on the sails
was quite time-consuming. Deft Gloss clear was sprayed on the entire structure and
sanded between coats for a smooth surface. Then, Testors enamel paint was applied
on the bottom of the hull. The effort paid off with a 1st Place ribbon at the 2004
Dixie Classic Fair, in Winston-Salem, North Carolina...
The Russian MiG-15 and French Mystère jet
airplanes were prominent first in the Korean War and then into the Vietnam era.
They were two of the earliest jet fighters in air warfare. Many of the American
jet planes were being modeled around 1956, when this issue of Young Men magazine
came out, but at least in domestic magazines, plans for foreign jobs were fairly
rare. Here are plans for the two aforementioned Russian and French jets which use
the Jetex 50 engine for propulsion. Construction is all balsa, consisting of
a minimal framework covered with 1/32" balsa...
Snow season arrived here in Erie, Pennsylvania,
already (13" on November 10th), and I didn't want to miss the chance to do some
flying off of snow skis. Last winter I mounted a pair of DuBro snow skis to my
Herr Engineering J-3
Cub and flew a couple times with them, but they were the standard model that
are too big and heavy for this 1/2A-sized model. DuBro's Park Flyer Snow Skis seemed
like they might be a better choice for the J-3, so I ordered a pair. The size is
just about right, but the vacuum-formed plastic was a bit too thin for me to confidently
install them on the J-3. I decided that they would be perfectly useable with a little
sturdying up. As can be seen in the photos, there are two stiffening slots...

A scheme I have considered for control line
models is one of the entries in the "Sketch Book" section of the February 1949 issue
of Air Trails magazine. Mr. Joseph Johnson shows how he used a moveable
rudder on his scale airplane to increase tension on the control lines when up elevator
is commanded. A similar system could be devised for stunt models which increases
right rudder (for CCW circles, left rudder for CW) as either up or down elevator
is fed in. Another option I have never tried is to have a
moveable
rudder controlled by a spring connected to a sliding bellcrank platform that
would increase outward rudder when line tension lessens, and decrease it when the
lines get tight. Such a system would be most useful for compensating for wind gusts
that slacken the control lines. Maybe some day I'll have the time to experiment
with that. A handful of other ideas are included...
Website visitor Bob wrote to ask that I
scan and post the construction article and plans for the
F-84G Thunderjet control
line model. It appeared in the July 1970 issue of American Aircraft Modeler magazine.
The unique feature of this model is that the power is supplied by the pilot. A fishing
pole and line is used to drag the airplane around the flying circle and a separate,
standard two-line elevator control is used to maneuver the model. Construction is
sheet balsa. Author Joe Wagner (well-known in the modeling world) claims that with
a bit of practice just about any aerobatic maneuver can be accomplished except for
the overhead routines like the figure eight...

The 1956 Air Trails magazine Annual
Edition reported on the World Championships in Germany for the International Wakefield
Cup, F.A.I Free Flight, and Nordic A/2 Glider events. The three '55 World Championships
were held in September at the U.S. Air Force's Finthen Airfield, near Wiesbaden,
Germany. Competition was fierce amongst European and American contenders. It is
worthwhile to remember that 1955 was a mere eleven years after the end of World
War II, and that former foes were gathered together for a sporting contest.
There could easily have been men there who, without knowing it, were competing against
military adversaries they met on the battlefield or in occupied towns a decade earlier...
This
rocket
boost glider called the Dyna-Soar was powered by American Telasco's version
of the Jetex 50 engine. Jetex rocket engines were quite popular with model airplane,
boat, and car builders through the early 1970s, at which point the fuel supplies
began to disappear. Most Internet sources posit that Imperial Chemicals Industries
(ICI) ceased making the fuel pellets due to a combination of liability and regulation
issues. ICI, based in Scotland, manufactured the Jetex fuel pellets* from a measured
blend of guanidine nitrate, 2,4-dinitroresorcinol, potassium nitrate...
Leonardo da Vinci is usually credited with
producing the first illustration of a helicopter concept. It employed a rotating
helical corkscrew device at the top in order to enable the craft and occupant to
"screw his way aloft, in much the same manner as Archimedes designed his eponymous
helical screw device to lift water from a lower level to a higher level. Water,
being dense and cohesive with itself, was easily elevated, whilst air, not being
dense or cohesive, did not yield to the same technique. In fact, if the "aerial
screw" were able to spin rapidly enough and was of an efficient aerodynamic design,
it would work. Here is a 4-screw drone to prove it. These "Windmill
Planes" presented in the February 1939 issue of Popular Science magazine represent
the state of the art at the time. Surprisingly omitted is an example of Igor Sikorsky's
helicopter design, which he first flew successfully in September...

is inherently subjective. The rationale for why any one image ranked two slots higher
than any other combines several factors, including our attempt to balance the list
between human spaceflight, satellite imaging, and planetary exploration. Many wonderful
images did not make the final cut - we couldn't convince the editors to give us
20 pages instead of 10. The list omits significant events from space history that

This sort of cutting edge technology used
to be the domain of military operations, but nowadays it can be found in amusement
parks and even at backyard parties. The parachute training facility which appeared
in a 1937 issue of Popular Mechanics magazine was real whiz-bang stuff
at the time. Although Russia's system is featured here, I have to believe other
countries were doing the same sort of thing. Using a
high power fan to boost the paratrooper trainee in a simulated parachute descent
was an excellent method of introducing men to the sensations and reactions to control
inputs via shroud lines. The story noes not mention whether the fan was forceful
enough to simulate a free-fall experience. Just today a saw a news item showing
such recreational free-fall machine companies called Urban Air and iFall...
Since first starting with control line model
sin the late 1960s, I always intended to build a multi-engine model of some sort,
but didn't get around to it until around 2016 when I began construction on a Douglas
DC-3 (maiden flight occurred in 2023). With the plethora of ready-to-fly (RTF) and
almost RTF (ARF) models on the market today at very reasonable prices, there is
no real good excuse for not doing it; so I'll have to stick with my bad excuses.
But I digress. This simple twin
"Wee-38" Lightning which

a pair of Cox .020 or .049 engines and solid balsa components. You could electrify
the model with equivalent brushless motors, ESCs, and a LiPo battery pack. It would
be nice if a series of ESCs would be marketed for twin motors, since unlike with

The
Space Race was one of the most significant geopolitical and scientific competitions
of the 20th century, driven by the rivalry between the United States and the Soviet
Union during the Cold War. It spanned from the late 1940s through the 1970s, with
a focus on achieving superiority in space exploration, a domain viewed as critical
not only for scientific advancement but also for military and strategic dominance.
Rooted in rocket technology developed during World War II, the Space Race transformed
the world's understanding of science and technology, culminating in the most dramatic
achievement: the landing of humans on the Moon in 1969. This treatise explores the
key milestones, the countries and key players involved, technological developments,
the interplay between military...

The
Cessna Skymaster (336/337) has always been my favorite twin-engined civilian
lightplane. A military version of it is designated as the O-2 Skymaster. For
as long as I can remember, I have threatened to build a control-line model of one.
Well, that time has finally arrived, and I began by ordering these plans from the
AMA Plans Service. It will be powered by a pair of 480-sized brushless motors, and
throttle will be controlled by a hand-held car/boat format transmitter, the one
I use on my control-line Douglas DC-3. I am modifying the fuselage construction
to accommodate the motors, and am adding formers to simplify the building process.

Fox model airplane engines had a reputation
for ruggedness and contest-winning performance, but were also notoriously difficult
to get started - at least without an electric starter. In 1961, when this full-page

were not in many modelers' field boxes, and particularly those owned by youngsters
whose modeling budget came from meager allowances and paper routes. Born in 1958,
I was 15 or 16 years old before being able to afford the luxury, and I remember
relentlessly flipping the propellers on my
Fox 15 and Fox 35 control line engines. Half the time when they...
If you have ever wanted to try your hand
(thumbs, to be more specific) at a floatplane, then this
1/2A size Aeronca
Champion which appeared in the March 1957 issue of Model Airplane News magazine,
is just the ticket. Although designed by Walt Mooney as a free flight ROW (rise-off-water)
model that easily converts between wheels and floats, modifications to 3 or 4 channel
radio control would be a snap, especially since the plans show separate construction
for the control surfaces along the hinge line. With about a 46" wingspan and lightweight
but strong construction, this model could easily have been designed with modern
electric power...
I did a quick Web search on how to
repair damaged book bindings, and as is typical, most of what is out there is
a rewritten regurgitation of other pages. Tape and glue are the order of the day
per those instructions, but that is really insufficient to effect a good repair
on books - particularly older volumes - which use string and fabric along the spine
to form a very rugged and durable binding for standing up to repeated use. When
you desire to restore a book to as close to its original condition as possible,
the more extensive method described in this 1965 Popular Mechanics magazine article
is needed. All the tools and materials required are described, as is instructions
