Michael M. wrote to request that I post this article, along with the ones for
the Satellite 1000 free-flight
champion, and The Giants of Free Flight. His reason was that he wanted to get
his flying team back together again in Bill Hunter, who passed away recently.
This 1972 American Aircraft Modeler magazine article on covering with Mylar is very
extensive and is another example of such efforts that were common in hobby
magazines of decades ago - a large part of my motivation for making them
available. It is rare...
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.
A flying machine in every garage is one which has not. Such a Jetsons...
We will be moving back to Erie, PA, where
overcast skies dominate, and the city lights kill views, so I am going to try to
sell this before leaving. I'd keep it as a museum piece for display if I was going
to have room, but we might be going into an apartment. The entire system has been
stripped down and refinished, with original components retained for authenticity.
Included are telescope, mount, clock drive, finder scope, 9 mm and 18 mm
eyepieces, 2x Barlow, dust covers. This is truly a unique opportunity. Please contact
me via e-mail if you are interested in buying it. Local pick-up only, or I'll deliver
for $50 within 100 miles of Greensboro, NC, with payment in advance...
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...
While looking for the edition of TV Guide
that published the first airing of "A Charlie Brown Christmas," I noticed that the
time period coincided with the launching of the
Gemini VII spacecraft.
In a stroke of good fortune, it indeed included an announcement that regularly scheduled
programming would be preempted as necessary to provide live coverage of the launch,
to give timely updates, and to coverage the splashdown in the Atlantic Ocean. 2:30
Gemini Space Flight The 14-day Gemini VII space flight is scheduled for launching
from Cape Kennedy's Pad 19 at 2:30 P.M. Astronauts Frank Borman and James A. Lovell

"An aviation company pushing the boundaries
of
solar-powered flight has successfully finished the first in a series of tests
for its uncrewed airplane, taking off from Mississippi's Stennis International Airport
for six flights high over the Gulf of Mexico. The company, Skydweller Aero Inc.,
says its aircraft - essentially a giant drone with a wingspan greater than a 747
- had one flight lasting 22.5 hours and another lasting 16 hours during the initial
testing campaign. The company says it is developing technology to enable its airplanes
to eventually spend months cruising at 40,000 feet, guided by a team of techs on
the ground and using only the sun for fuel. The top of the plane is equipped with
17,000 solar cells..."
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...
"Drones
will be deployed for long distance inspection of infrastructure as well as site
security following new rule changes published by the UK Civil Aviation Authority.
The aviation regulator's new rules will enable drones to fly beyond the visual line
of sight (BVLOS) of remote pilots in so-called 'atypical' operations through its
new policy for atypical air environments (AAE). BVLOS flights have been taking place
in the UK for several years, but these flights have occurred primarily in trials
under strict restrictions..."
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...
"On the occasion of the 50th anniversary
of the National Aeronautics and Space Administration, which began its operations
on October 1, 1958, we offer this list of the
50 most memorable images from NASA's history. We recognize that any such ranking
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
were not NASA achievements..."
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
appeared in the December 1959 issue of American Modeler magazine, uses
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
brushed...
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...
This article appeared in the November 2024
issue of Astronomy magazine - not sure why. "Brothers is a place that has
somehow slipped outside the passage of time. Located in a sea of sagebrush in central
Oregon, this former stagecoach stopover once serviced horse-drawn migrants bound
for the Willamette Valley. Thanks to the nonprofit organization
OregonRocketry, Brothers has outlasted the surrounding ghost towns to find new
purpose as one of the preeminent high-power rocket launch sites in America. The
group has purchased land and established a site out here in coyote country for the
advancement of amateur rocketry and education of future aerospace engineers. They
have a waiver from the FAA that currently allows them to blast the things nearly
four miles into the air..."
"Japanese
operator SoftBank announced that the Sunglaider, its large-scale solar-powered uncrewed
aircraft system (UAS) designed for
High Altitude Platform Station (HAPS) stratospheric telecommunications, was
utilized in a field trial conducted by AeroVironment and the U.S. DoD in New Mexico,
the U.S. During the trial, carried out in early August, Sunglider succeeded in achieving
stratospheric flight, the Japanese operator said. With a wingspan of 78 meters and
the capability to carry payloads weighing up to 75kg, the Sunglider is larger than
other publicly announced HAPS UAS..."
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.
Mr. Welch's original omitted formers in the cabin area...
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
advertisement appeared in American Modeler magazine, electric starters
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
for assembling a book...
