Getting Started in R/C
column introduces electronic schematic symbols commonly found in transistorized radio control equipment. In 1968,
when this article was printed, nearly all solid state circuitry was built from individual discretely packaged
transistors and diodes; integrated circuits (ICs) were still a few years off for R/C equipment. If you look at
a modern transmitter or receiver schematic, you might not see a single transistor
you thought you heard "Taps" playing in the background recently as you bought a copy of
Flying Models at the local hobby shop,
it might be because it is now out of publication. Carstens Publications recently sold its other two magazines,
Railroad Model Craftsman and
Railfan & Railroad, (which
will be continued) to White River Productions. It is a sad end to a great magazine - probably the first
model airplane magazine I ever read back in the late 1960s. Its demise is reportedly due to a dying
(literally) population of modelers who build kits and/or build from plans. Chinese-built
RTF and ARF rule the world now. Thanks to the good folks at Carstens who produced
Flying Models since 1928!
of Melanie's family's relics is this pine clothes
chest. After more than 100 years of use and abuse, this chest was in dire need of restoration. Construction
is very low density pine, with dovetailed corners. Finish was a clear varnish with no stain. The bottom, back,
and inside had no finish at all. Restoration consisted of knocking apart and re-gluing most joints, sanding, and
filling in the multiple dings and scratches where they were really deep. Minor imperfections were kept for the
mantel clock is a multi-generational
heirloom. It was not expensive, but had emotional value. Melanie's family hearkens from the York, Pennsylvania,
region and this clock, I discovered, was manufactured by the Ansonia company and sold by Will K. Rebert,
Watchmaker and Jeweler, in York. Her parents gave it to me for Christmas of 2006, and I decided to refinish it
and return it to them the next Christmas. Unfortunately, Melanie's father passed away from cancer last summer,
but we were able to present it to ...
are many videos on YouTube showing some pretty ingenious dust collectors for radial arm saws. Most use a fairly
small enclosure located just behind the fence, with a shop vac attachment for forcefully inhaling the sawdust.
They appear to work extremely well for cuts that are at 90° to the fence and to the table surface. Maybe my interpretation
of the dust collectors is wrong and they adapt to any angle. Since I only have a small shop vac and do not like
to have to turn it on every time I make a cut, my ...
last flying (according to the attending crew)
Curtiss C-46 Commando made an appearance at the 2014 Winston-Salem
Airshow. It looks like a bloated C-47 Skytrain. They were only asking for a $3 donation to look around inside,
which is a shame since other aircraft like the C-54 were fetching $5 or more. When costs for keeping it airworthy
and touring run the in neighborhood of $3,000 to $5,000 per hour, it takes a lot of visitors to pay the bill.
Of all the worthless garbage the government wastes money on (both human and otherwise),
letting these relics of our past disappear is shameful ...
is a really unique control line scale model project. This one involves two separate airplanes and two separate
pilots - one to fly the twin-engined
C-46 Commando tow plane and
the other to fly the CG-15 troop
glider while it is attached via towline, and then released for landing. Doing so is no different than two
aerial combat pilots chasing each other around the sky. The troop glider has its own elevator control and also
uses a third line to release the tow line attached to the C-46. Anyone who has seen an R/C power plane tow an
R/C glider knows that ...
two very good flights with the Astron
Falcon two weeks ago. Both almost 90 seconds. Like most rocket gliders, it is very sensitive to CG balance.
But once dialed in, it will just float. Last Saturday at the sod farm in Moriarty, we put up a flight with
an A8-3, as usual. Very light breeze, but it was enough to slowly move it off the field while in a thermal. Slowly
coming out of the ...
have heard of the pumped laser and maser. Here is a new type of pumped energy system: the vaser. 'Laser' is an
acronym for 'light amplification by stimulated emission
of radiation,' and 'maser' is an acronym for 'microwave amplification
by stimulated emission of radiation.' I coined the term 'vaser'
after reading an article in the June 2014 edition of Model Aviation about a relatively new form of radio
controlled model sailplane sport -
dynamic soaring - that, using a specially developed technique to exploit geography and prevailing winds, produces
aircraft speeds of more than 400 miles per hour. Per my definition
object with these stick and tissue
fighter airplane shaped kites
is to use the sharp-edged sand that is glued to the kite string to saw through your opponent's string until it
breaks. Part of the trick is that there is a long section of rubber in the kite string so that the kite is continually
zooming back and forth, up and down. This provides the sawing motion needed to cut the string. The original plan
calls for a single string, but it might be possible to work out a dual string control so that the kites can be
maneuvered, thereby ...
is a model airplane design that should prove to be very interesting to try out in order to determine whether its
designer, Roy Clough, Jr., is correct about his theory of the aerodynamics of the
curve wing center section. The pusher configuration with the reward-facing engine between twin tail booms
probably kept a lot of people from trying it back in the 1950s when small electric starters were not commercially
available for .049 engines. Today, the issue can be mitigated entirely simply by converting
and Rockets website visitor Jack A. wrote to request this article and plans for Doug Spreng's "Stormer"
radio controlled airplane model. It appeared in the April 1961 edition of American Modeler, where you
read the opening line that says, "'Stormer' is a return to the older style R/C jobs ..." R/C had not really been
around all that long by 1961, so reference to "older style" is kind of funny. It is interesting to read the author's
discussion on airframe design and control surface shape and deflection amount. The reed-type radio equipment required
careful consideration to such details in ...
August 26 2013, Melanie and I toured the inside of this Consolidated PBY-5A
Canso (PBY-5 is the Catalina) while it was on display at the Erie International
Airport. It was on tour by a crew from Canada, which is appropriate since it was this particular airplane was
manufactured in Canada in 1944 by the Vickers company. World War II ended before it could ever see combat
reconnaissance duty. The PBY-5A has a wingspan of 104 feet 0 inches and is powered by a pair of 1200 horsepower
Pratt & Whitney R-1830-92 Twin Wasp radial ...
J.'s son's Boy Scout Troop 117 in Jasper, AL,
built four sets of these 12'-long wooden bleachers using their
own modified version of my plans (see below). They will be used in a equine therapy
program. The project helped to earn an Eagle Scout badge. Boy Scouts are an increasingly rare source of good works
and high moral standards. Congratulations!
does not sell the D-13 engine line anymore, but it does sell a D-12. The D-13 produced 9 pounds of thrust according
to this article and the 1971 Estes catalog,
whereas according to the 2014 Estes catalog the D-12 produces only 7.4 pounds. If you want similar performance
with readily available rocket engines, you will need to get them from a company like Aerotech, which makes an
F30FJ-6 model that produces 9 pounds of thrust. With that solution you're look at about $12 per launch. I believe
that with modern materials like graphite for spars and/or leading edges, and the lightweight airborne systems,
the flying weight ...
is a nice set of drawings for building a scale model of the
Gere Sport biplane. The tail surfaces
are large so that it would probably not be necessary to enlarge them as is often necessary for rubber powered
models. The Gere Sport, with a wingspan of only 19 feet, was originally designed by 19-year-old Bud Gere (one
foot per year, I suppose). An R/C version of the Gere Sport with a 36" wingspan was published in R/C Modeler in
of the nice things about having a website is that people from all over the world are able to see what you post.
This very nice lady from Spain saw Melanie's picture and wrote to us in the year 2011 about obtaining the pattern
for it. We found the booklet on eBay, and since she could not purchase it from Spain, she sent us the money and
we procured it for her and mailed it to her in Spain. Honestly, we had forgotten about it and then voila! A week
or so ago Miss Mortes
e-mailed these two pictures to...
is always hard to pass up a ride in a vintage aircraft. Usually, the price is not too awfully high, so on the
rare occasion that Melanie and I go to an airshow, we try to be sure to fly in something. Last summer, we rode
on one of the 11 flying Ford Trimotors left in the world when it was visiting Erie Airport in Pennsylvania. The
cost was an incredibly affordable $75 each, so we couldn't resist. This time we were at the airshow in Winston-Salem,
North Carolina, and there was a crew with a
Bell "Huey" UH-1 Iroquois and a Bell...
you like looking at pictures of
model boats of all sorts, then this is the article for you. The 1995 Annual edition of Air Trails
published this piece to demonstrate the huge variety of model boats that we built and sailed in the day, with
loads of talent crammed into each pixel. America was filled with craftsmen who had built and operated the equipment
that resulted to victory in World War II. Their skills were on ample display in the form of hand-built steam
engines and internal combustion engines, rubber-powered submarines some of which were 5 feet long, radio controlled
tug boats and even speed boats sporting not just one but two...
ubiquitous presence of cameras in cellphones, worn around necks to capture entire days of activity, and compact
models that fit in a shirt pocket for easy retrieval, has resulted in billions of images being captured in the
last decade. You have probably seen the time lapse videos of kids and pets growing from newly born to 12 or 15
years old after daily pictures had been snapped. Nobody from this time forward will have any problem finding a
visual record of him/herself. In the 1960s, the only people who had the benefit of photographic progressions of
their lives were the famous and...
Wallops Island Station was located about 100 miles as the rocket flies from where I grew up in Mayo, Maryland.
That was close enough that many of the colored skies created by sounding rockets conducting atmospheric research
were visible. Local newscasters would broadcast announcements ahead of tests so that the populace wouldn't think
we had been invaded by aliens or were not under attack by the Russkies. This article on the

was the AMA Nats that almost wasn't. The U.S. Navy, which for year prior had helped organize and finance the Nationals
competitions, decided it was no longer going to do so. The reason given was that its primary mission - to promote
aviation as a career to boys and young men who might eventually decide to make the Navy a career - had suffered
due to a continually decreasing percentage of boys and young men participating in the competition. Thanks to heroic
efforts of members of both the Navy and the AMA, the 1968 Nats went on to become possibly 'The Greatest Ever."
like with the old commercial jingle that went, "Everybody doesn't
like something, but nobody doesn't like Sara
Lee," I can pretty confidently substitute "seaplanes" for "Sara Lee." The
Grumman Widgeon was one of many iterations
of their twin engined amphibious airplanes that is immediately recognizable to most people over the age of 40.
In fact, the Widgeon was the seaplane that appeared each week on the 1970s television show "Fantasy
Island." It was "Ze plane! Ze plane!" that Tattoo would call out at the beginning of each episode.
is amazing to ponder that as recently as the 1970s that the U.S. Air Force and U.S. Navy officially sponsored
model aviation events. Hmmm... it just occurred to me that the 1970s was 40 years ago - amazing! 1970 was the
year of the 20th annual base championships where the winners were sent to represent the
USAF team. These
guys were in the middle of the Vietnam War at the time which, along with being called upon to move to new bases
every few years, made impressive showings in spite of difficulties not imposed upon their civilian competitors.
Note that Sgt. Gordon Ford, who was featured in "One-Man
Air Force" in the March 1970 edition of AAM, had entered his C-5A Galaxy...
had totally forgotten about this nice cake to memorialize the life and works of Charles M. Schulz when he died
in the year 2000. His Peanuts characters have
been a lifelong favorite of mine. Neither of us remembers why she choose this particular comic strip. In retrospect,
the one where
Snoopy ate the carrot nose of his 'best friend' snowman after it melted might have been more fitting (just
as we ate the cake).
Mail Online website has a big story for the 70th anniversary of Hitler's forces raining approximately
V2 rockets (the 'V' is for 'Vergeltungswaffe,' or 'Vengeance Weapon') down upon British cities during the
final months of World War II. Included is an interactive Google map that shows locations and displays statistics
on deaths, injuries, destruction, etc.; e.g., "Axminster Road , January 13, 1945, ~48 Dead."
wide view of the Martin (now part of the Lockheed-Martin conglomerate)
model shop brings
back memories of when I worked as an electronics technician at the Westinghouse Oceanic Division in Annapolis,
Maryland. We had a bunch of guy in lab jackets sitting around at benches with out machinist's tool boxes open.
Most people had the Gerstner, Craftsman, or Union brand. Serious tool accumulators had the large model with the
big drawer in the middle for hold a machinist's reference manual (my shop did electronics
assembly and prototype building, so we kept other things in ours). As with so many other things, I eventually
sold my toolbox, but, fortunately, there is almost nothing you cannot buy on eBay, so a couple years ago I bought
one like what I had before. I'm not sure how much model making...
couple years ago I scanned and posted just the plans for this
Beechcraft T-34 Mentor from the February 1974
American Aircraft Modeler magazine. It is a fully aerobatic 60-size scale model. Finally, I went
back and scanned the article, too. It mentions availability of a fiberglass cowl and a formed plastic canopy from
Sig, but I seriously doubt they are available today. Standard balsa and aircraft plywood construction is used
otherwise. Plans for this fine model were draw...
1974, I was flying some of my first
R/C gliders -
probably a Mark's Models Windward or maybe the Windfree (in that order). During that
time, I tried hard to locate a group of sailplane flyers in my area around Mayo, Maryland, but to no avail. The
nearest R/C flying field was about 30 miles away in Upper Marlboro, MD, where the PGRC club field used to be.
My family's car was held together with chewing gum and bailing wire, so it wasn't often that I could talk my father
into driving me out there, and the few times that he gave in to my whining, there were never any gliders present.
So, when I would see articles like this in the modeling magazines, my envy level would increase...
Druschitz, winner of this quiz and also the young man holding the trophy in the photo, wrote recently to request
that I scan and post this
R/C Sailplane Quiz that appeared in the October 1974 edition of American Aircraft Modeler. It
is always nice to get a note from someone who appears in image and/or print form in the old articles. It has been
40 years since the event, which makes Mr. Druschitz about st two years older than me. To win the contest, he answered
9 out of 10 of the questions correctly, and also took 1st place in the Jr./Sr. Team event.
