Planes That Didn't Make It

Planes That Didn't Make It, March 1937 Flying Aces - Airplanes and RocketsDuring World War I, the United States spent $1,500,000,000 on military aviation, resulting in the development of various advanced aircraft designs. This 1937 issue of Flying Aces magazine mentions a few of them. This was 19 years after the armistice. Although these planes did not see combat due to the war ending sooner than expected, they showcased American ingenuity and engineering prowess. Notable examples include the L.W.F.G.2, which had a top speed of 130 mph and carried seven guns; the Loening monoplane, which was the fastest two-seater fighter at the time with a speed of 146 mph; and the Curtiss single-seater fighter, capable of reaching 160 mph. These aircraft laid the foundation for modern American military aviation...

Paul Harvey Views

Paul Harvey Views, December 1974 American Aircraft Modeler - Airplanes and RocketsWhile looking through some old issues of American Aircraft Modeler magazine, I was quite surprised to find that none other than radio great Paul Harvey is (or was) a builder and flyer of radio controlled airplanes. There was a feature article done by Paul Harvey in one of the issues in the 1974 timeframe. Mr. Harvey then wrote a regular column titled "Paul Harvey Views." Understandably, the column only ran for a few months - probably because of his extremely busy schedule. This one is from the December 1974 edition...

A 4G Moon Suit

Axiom Space's 4G Moon Suit - RF Cafe"In August last year Nokia and Axiom Space announced they were working to equip the latter's next-generation lunar spacesuits with 4G/LTE connectivity for the for NASA's Artemis III mission to the moon. The idea is that arming the new spacesuit, called Axiom Extravehicular Mobility Unit (AxEMU), with high-speed cellular-network capabilities means it can support HD video, telemetry data and voice transmission over multiple kilometers on the moon. This means the Artemis III crewmembers will then be able to capture real-time video and communications..."

Huffy 3 Timberline Men's Bicycle Restoration

Vintage Huffy 3 Timberline, 3-Speed Men's Bicycle Restoration, early 1980s - Airplanes and RocketsPreviously I posted the first part of a story about two 1980s-vintage bicycles I bought from a guy off craigslist. That was the complete teardown and restoration of Melanie's Columbia Commuter III, 3-speed women's model. This page has photos from doing the same thing to my Huffy 3 Timberline, 3-speed men's bicycle. One important aspect worth repeating is the use of Krud Kutter for removing all the oil and grease. The stuff is amazing. I soaked all the parts overnight that would fit in a bucket filled with a gallon of it. Upon removing even the grimiest and greasiest components like the gearbox, bearings, and the chain, I discovered they were squeaky clean. A toothbrush removed...

Calvin & Phineas Hamming It Up®™: The Phantom QRM

Calvin & Phineas Hamming It Up®™: The Phantom QRM - RF CafeBeing a long-time fan of John T. Frye's "Carl & Jerry" technodrama™ series, I have been intending to attempt a contemporary version which has a Ham radio theme. Its purpose, as with "Carl & Jerry," is to encourage young people to adopt electronics as a hobby and even as a career, while using Amateur Radio as an enticement. Ham radio offers practical experience in electronic theory, fabrication, and operation in an environment that encourages community service, mentorship, camaraderie, and self discipline. In the U.S., there are approximately 760,000 licensed amateur radio operators; worldwide, the estimated number is around 3,000,000. The American Radio Relay League (ARRL) and the International Amateur Radio Union (IARU) track these statistics. This title of the series is, for now anyway, "Calvin & Phineas Hamming It Up," and the first adventure is called, "The Phantom QRM." Call signs are fictitious, chosen to hopefully not step on someone's real call sign. The boys' names derive from my grandson's name...

Winning the National Radio Control Meet

Winning the National Radio Control Meet, March 1940 QST - Airplanes and RocketsYou might wonder why an article entitled "Winning the National Radio Control Meet" for model airplanes would appear in the ARRL's QST magazine. The answer is that back in 1940 when it was published, a Ham license was required to operate a radio control (R/C) transmitter. There were no license-free bands for hobbyists as there are now. In fact, it wasn't until 1976 that the FCC suspended their requirement for registration as an operator, which has returned in the form of an FAA "drone" (aka USAS) pilot directive. The author, William (Bill) E. Good (W8IFD, W2CVI), was the twin brother of Walter (Walt) A. Good (W3NPS), both of whom held doctoral degrees in and physics, and were referred to as "the fathers of radio control." The photo of Bill shows his station...

New Radio Control Gear for Model Airplanes

New Radio Control Gear for Model Airplanes, August 1940 QST - Airplanes and RocketsOften when I see photos of some of the early radio control gear for model airplanes, I have a simultaneous reaction of aghastness and marvel at the crudity and ingenuousness, respectively, of the electromechanical devices - the same kind of reaction I have to stories about early surgical procedures and equipment. In 1940, when this article appeared in the ARRL's QST magazine, successful takeoffs and landings were considered notable events not so much because of pilot ability (or inability), but because of the low reliability of available electronic and mechanical gear. Vacuum tubes with attendant heavy, high voltage power supplies, and heavy metal gears and shafts required large airframes to support...

Dope Can

Dope Can, from April 1957 American Modeler - Airplanes and RocketsAmerican Modeler magazine published stories on many forms of modeling including airplanes, cars, boats, and rockets. A lot of attention was paid to teenagers in order to encourage a pursuit of careers in engineering and science. In case you don't know, the U.S. Navy used to sponsor the AMA Nationals specifically to attract young modelers into the service. This 1957 edition reports on the activities of James M. Blackmon, Jr., who was the nation's youngest rocket builder to receive national recognition by the American Rocket Society. He built in his basement a 6' tall liquid-fueled rocket...

Sketchbook - Hints & Kinks

Sketchbook - Hints & Kinks, November 1961 American Modeler - Airplanes and RocketsThis November 1961 installment of American Modeler magazine's "Sketchbook - Hints & Kinks" column has a very interesting alternative to the traditional "stooge" that is used when a helper is not available to assist in launching a control line airplane model. The drawing is a bit confusing, but what's going on is the flyer starts and holds the model at a point just outside the dashed line circle, and the pole is set midway of the diameter of the circle. That gives the airplane half the circle to take off before it is free of the pole. Then, it is flown normally. I can see where, as the inventor states, the process could be a spooky until the flyer has gotten used to it...

Commercial Blended Wing Aircraft

Delta, JetZero Partnering to Develop Blended Wing Aircraft - Airplanes and Rockets"Delta Air Lines and JetZero are partnering to develop a commercial blended-wing-body (BWB) aircraft that would be 50 percent more fuel efficient than those in current operation, the carrier has announced. The development, which builds upon a Department of Defense's Defense Innovation Unit (DIU) investment in the BWB technology, comes as Delta continues to focus on its goal of net-zero emissions by 2050. BWB aircraft received a boost in 2023 for its BWB aircraft when the U.S. Air Force awarded it $235 million over four years for the development and production of a full-scale demonstrator. The aircraft is to take its first flight in 2027..."

For the Tenderfoot: Baby Biplane

For the Tenderfoot: Baby Biplane Article & Plans, October 1971 American Aircraft Modeler - Airplanes and RocketsWebsite visitor Tom A. wrote to ask me to post this "Baby Biplane" article from the October 1971 edition of American Aircraft Modeler magazine. It was one of the For the Tenderfoot models that the magazine published almost monthly for many years. The Baby Biplane uses a very simple structure but as with any biplane of any size, the extra work of building a second wing and adjusting it to fly properly take a little more work. Using the modern trick of printing a colored patter on the Jap tissue prior to attaching it would make Baby Biplane look really spiffy...

Skydancer Rocket Boost R/C Glider

Skydancer Rocket Boost R/C Glider Article & Plans, March 1971 American Aircraft Modeler - Airplanes and RocketsEstes 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 (p94), whereas according to the 2014 Estes catalog the D-12 produces only 7.4 pounds (p79). 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 could be significantly reduced, and a much lower thrust (and cost) engine could be used...

American Model Aviation Magazines: A Brief History

American Model Aviation Magazines: A Brief History - Airplanes and RocketsHere is a detailed account of American model aviation magazines, presented in chronological order of their founding, including publication date ranges, editors' names with their tenures where available, and a description of each magazine's purpose and target audience. These titles - spanning from the early 20th century to the present as of February 2025 - reflect the evolution of model aviation from rubber-powered gliders to modern RC drones. The data is drawn from historical records, enthusiast archives, and trends A conceptual timeline follows, imagining the overlapping publication spans, though an image isn't generated here - envision a horizontal chart from 1915 to 2025 tracking these magazines' lifespans...

Aeronca Model L Series

Aeronca Model L Series, May 1969 American Aircraft Modeler - Airplanes and RocketsLow-wing airplanes had not quite caught on with the flying public prior to World War II, so Aeronca had an uphill battle in gaining acceptance of its "Model-L" series of planes. It ended up being a complete success. The article has an interesting tale of salvaging partially-complete airplanes during a flood in Cincinnati in 1937 using techniques that would never be allowed in today's highly regulated and monitored world. Interestingly website visitor Glen M. sent me a photo of an Aeronca LC on floats - the "LCS" model the author of this American Aircraft Modeler magazine article suggests might have never been built. To be fair...

ChatGPT vs. Grok Comparison and Contrast

ChatGPT vs. Grok Comparison and Contrast: Kirt's Cogitations™ #369 - RF CafeAs of February, 2025, when this is being written, several major artificial intelligence engines are publicly accessible through free tiers, temporary free access, or subscription-based models with broad availability. I have been evaluating ChatGPT-4 (OpenAI) and very recently, Grok 3 (xAI). I requested from both ChatGPT and Grok, tables of comparison and contrast between the two, based on "Aspect" criteria I provided. Those results are presented below. They seem to be mostly honest assessments. Perhaps not surprisingly, Grok 3 often invoked the name of its founder (Mr. Musk) during my interactions with it on wireless communications topics. I will reveal more on that later...

Experimental Aircraft Accident Rates Down

Experimental Aircraft Accident Rates Down - Airplanes and Rockets"September 30 marked the end of the FAA's fiscal year and with it, the annual conclusion of the annual 12-month tracking of fatal accidents among experimental category aircraft. The preliminary numbers from the agency received late last week appear to present an excellent snapshot of safety over the past year. While the final totals are still being tabulated, the initial total of 37 accidents is well below the FAA's not-to-exceed figure of 46 for the period. That includes 29 fatal accidents in homebuilt aircraft. More details will be available in the coming weeks as the FAA's annual total of GA activity..."

Hi Johnson's Docile R/C .35

Powerplant Revue: Hi's Radio Mill Proves Potent Yet Docile .35, February 1962 American Modeler - Airplanes and RocketsHi Johnson was a well-known designer and manufacturer of model airplane engines in the middle of the last century. His series of throttled engines was widely used in the early years of radio control. A lot of research went into producing the engines to produce long lifetime, easy starting, and consistency of operation. The Johnson 35 R/C, which is the subject of this 1962 American Modeler magazine article, was one of the first to used dual ball bearings on the crankshaft, contributing mightily to the accomplishment of the aforementioned goals. The state of the art for all types of model flying had advanced to where pilots could expect...

Model Aviation in the 20th Century

Model Aviation in the 20th Century (ChatGPT vs. Grok 3) - Airplanes and RocketsWith all the news lately about AI (artificial intelligence) and whether the good it can do offsets the bad, I decided to ask both Grok 3 (X.ai) and ChatGPT (OpenAI) to compose short essays on a few model aviation related topics. While that will not settle the aforementioned dilemma, it will provide a peek into the "good" side of what AI can do. I have been using ChatGPT for a few months, and just recently Grok 3. Here is a side-by-side, unedited comparison of the results of submitting the exact same query to both AI beings. Note that the content for both Grok 3 and ChatGPT is fairly brief, not long-winded treatises that would fill a book. Having used both for a while, it seems when you hear about students using AI...

There's Nothing Mysterious About Ducted-Fan Models!

There's Nothing Mysterious About Ducted-Fan Models!, Model Annual 1956 Air Trails - Airplanes and RocketsAs with most things these days related to model airplane components, extensive research into materials, structure, and functionality have been thoroughly researched and engineered to the point where the modeler has little more to do that install parts into his craft. Parameters have been thoroughly analyzed using computers over a wide range of input stimuli to determine the optimal configuration. The effort dedicated by author Wayne Schindler to design and conduct an experiment to determine the optimal dimensions and shapes for a ducted fan propulsion system is nothing short of academic. His efforts produced a list of design parameters to consider when building a ducted fan-powered model airplane. The net result in Mr. Schindler's case was an amazing 325% thrust improvement...

Chance of Space Debris Entering Airspace Calculated

Chances of Space Debris Entering Busy Airspace Calculated - RF Cafe"A study from Canada has found a 26% annual chance that space debris will re-enter the atmosphere and pass through a busy flight area. The chance of space debris hitting an aircraft is very low, but the research from a team at the University of British Columbia highlights that the potential for uncontrolled space debris to disrupt flights and create additional costs for airlines and passengers is not. The research is published in Scientific Reports. In 2022, a re-entering 20-tonne..."

Inside Britain's Newest Jet: Gloster E.1/44

Inside Britain's Newest Jet: Gloster E.1/44, October 1948 Popular Science - Airplanes and RocketsThe Gloster E.1/44, presented in this 1948 issue of Popular Science magazine, was a British experimental jet fighter developed in the 1940s as a potential single-engine counterpart to the twin-engine Gloster Meteor. Designed by the Gloster Aircraft Company to meet Air Ministry Specification E.1/44, it was powered by a Rolls-Royce Nene turbojet and featured a sleek, straight-wing design with a tricycle landing gear. Initially conceived as a simpler and more economical jet fighter for the Royal Air Force, the project faced numerous delays due to shifting priorities...

DIY Airplane Detector

DIY Airplane Detector, May 1942 Popular Science - RF CafeDuring World War II, Americans, Britains, Frenchmen, and other civilians were seriously engaged in helping to defend their homeland. Those who were not in the military gathered bottles, tin cans, tires, and clothing to use in the war effort. Others volunteered at the Red Cross, veterans' hospitals, and USO offices. Some stood guard at their nation's seashores and land borders, both as armed sentries and as troop and aircraft spotters. As part of the civil defense effort, listening devices were built to help detect the sound of approaching airplanes. In patriotic tradition, magazines like Popular Science published many articles to assist the population contribute. Here is a plan for a "Homemade Plane Detector." It used a horn "antenna" that...

AMA Relocation to Muncie, Indiana 1992

Academy of Models Aeronautics (AMA) Relocation to Muncie, Indiana 1992 - Airplanes and RocketsAs a member of the Academy of Model Aeronautics (AMA) since around 1971 (AMA # 92498), I have witnessed a lot of change in the organization as well as in the model industry. When I first joined as a teenager, AMA headquarters consisted of rented office space in a Washington, D.C., building, Richard Nixon was president, and the war in Viet Nam was on nightly news. AMA headquarters moved into a brand new building, which included museum space, on purchased property in Reston, Virginia, in 1983. A growing AMA membership and the desire to consolidate national competitions to a central location resulted in establishing residence in Muncie, Indiana, where the 25,000 square-foot Frank V. Ehling Complex celebrated its grand opening in 1992. Since then, an additional 25,000 square feet of space...

World's Radio Control Endurance Record

World's Radio Control Endurance Record, December 1956 American Modeler - Airplanes and RocketsI did not bother to look up what the world record endurance flight length is for an R/C glider as of this writing, but in December 1956 when this article appeared in the first edition of American Modeler magazine, a team of three modelers did 8 hours, 34 minutes and 21 seconds at Torrey Pines, California. That would be an amazing accomplishment with today's equipment, but these guys did it with a vacuum tube receiver and an escapement mechanism driven by a twisted rubber band - rudder-only! No elevator control, no flaps or speed brakes, no gyroscopic stabilization, no proportional rudder deflection. It was left, center, or right...

Cox PT-19 Trainer C/L Airplane

Cox PT-19 Trainer C/L Airplane - Airplanes and RocketsThis is the earliest known photo of me with a control line airplane - a Cox PT-19 Trainer. I'm guessing it was summer of 1969, when I would have been 12 to 13 years old (my birthday is August 18, so it could have been before or after). I remember that 1969 was the year because it was the year that Hurricane Camille tore up Biloxi, Mississippi (where I would many years later be stationed for electronics training in the USAF) and the rains even in Mayo, Maryland, where I lived, were torrential. It is the airplane with which I first learned to fly control line. There was another Cox control line plane that I had prior to the PT-19 Trainer, but I cannot recall...

Bill Gaylord's Guillow's R/C Electric Conversions

Bill Gaylord's Guillow's R/C Electric Conversions - Airplanes and RocketsMr. Bill Gaylord has been gracious enough to allow me to post photos and information about his fine Guillow's free-flight model airplanes that he converted to electric powered R/C. The level of craftsmanship is incredible both in the frame-up and the covering and finish. You can find lots of photos and details of the build on the RCGroups bulletin board. I do not see whether he has ever flown any of these models. My guess is that with the structural beefing up required to support the motor, battery, and R/C gear results in a high wing loading. I personally would never dare risk these models by trying to fly them! They would all spend their days as hanger queens - display only...

Development Highlights

Development Highlights, October 1950 Air Trails - Airplanes and RocketsIt is kind of amazing that as recently as 1950, aircraft manufacturers were still using radial engines on new aircraft. This 1950 issue of Air Trails magazine reports on the Navy's P2V-4 Neptune, the latest model of Lockheed's patrol bomber, which is powered by two 3,200 horse power Wright Turbo-Cyclone radials. In-line engine formats are definitely more streamlined, but from a maintenance perspective, being able to change out a single cylinder rather than an servicing the entire block was definitely handier. Having only ever ridden in one airplane having a radial engine (a Ford Trimotor), I can't say...

Eavesdropping on Satellites

Eavesdropping on Satellites, February 1963 Popular Electronics - Airplanes and Rockets1963 was five years since America's first communications satellite, Echo, was placed in orbit. Echo was a passive, spherical reflector that merely provided a good reflective surface for bouncing radio signals off of. By 1963, when this Eavesdropping on Satellites article appeared in Popular Electronics magazine, the space race was well underway and active communications satellites were being launched at a rapid pace. Spotting and tracking satellites has long been a popular pastime with two types of hobbyists: amateur astronomers using telescopes and binoculars, and amateur radio operators using antennas and receivers...

"Wrongway Feldman's" Krieder Reisner KR21 on Gilligan's Island

"Wrongway Feldman's" Krieder Reisner KR21 on Gilligan's Island - Airplanes and RocketsThe other night Melanie and I were watching an episode of the old Gilligan's Island television show titled "Wrongway Feldman," which was about a long-forgotten, famous aviator who took a wrong turn during a race and ended up being stranded on the same island as seven famous castaways. The "Spirit of the Bronx" airplane featured in the show was referred to by Wrongway as a Krieder Reisner KR21. It is a right nice looking biplane. I immediately hit the pause button and looked it up on Google. The KR-21, according to the EAA AirVenture Museum's website, was manufactured in the 1929-1930 timespan, had a 22'-7" wingspan, and a 125 hp Kinner B5 (R-440), 372 cubic inch, 5-cylinder radial...

How to Target AirplanesAndRockets.com for Your Google Ads

Google AdSense - it makes good sense - Airplanes and RocketsSome companies have expressed an interest in being able to target Airplanes and Rockets via the Google AdSense program. Yes, it is possible to do that. As you might expect, finding the exact information on the Google AdSense website is a bit difficult. This short video does a good job summarizing exactly how to implement the "Ad Targeting" option, then "Placements," and then add "Websites." Just enter   airplanesandrockets.com   . There are other settings to optimize your advertising campaign with keywords (both included and excluded), pricing, scheduling, statistical data collection and reporting, etc. If you are currently using Google AdSense, then please consider this method, and if you are not using AdSense, now would be a good time to look into it. I have had reports from some companies that experience great results using AdSense (not just on Airplanes and Rockets)...

WAG - Hand-Held Relayless Dual Transmitter

WAG - Hand-held Relayless Dual Transmitter (January/February 1963 American Modeler) - Airplanes and RocketsIf you like re-visiting the old days of radio control (notice I didn't use the adjective "good") to see how far we have come in terms of equipment, then this article from the January/February 1963 edition of American Modeler magazine is just what you are looking for. Dr. Walter Good (no relationship to the adjective mentioned above) developed this "handheld" transmitter at a featherweight seven pounds to replace his previous 32-pound monstrosity. Modern digital transmitters with 100,000x the processing capability weigh less than a pound. Being a tube circuit admirer, I have always been impressed at what designers were able to do with so little. Some day our kids will look back at the Futaba 14M and wonder how we managed to keep model sin the air with the need to actually hold a transmitter at all (brain wave control will be standard equipment)...

Lightweight Proportional Servo

Lightweight Proportional Servo, from September 1962 American Modeler Magazine - Airplanes and RocketsGlass-filled nylon and other types of high strength plastic for gears and structural components were things of the future in 1962 - about a decade or so at least - when this article appeared in a 1962 issue of American Modeler magazine. Likewise for high torque, miniature motors that used powerful rare earth magnets - at least at a price affordable to hobbyists. Not only were early servos big and heavy, but they drew a lot of current from the airborne battery, were slow, and were driven by analog proportional circuits (i.e., low positional precision). Servos available today are modern marvels of materials, mechanical, and electrical engineering. While it was not too hard to imagine in the 1950s and 1960s how a servo might be improved over the (then) state of the art, it is hard to imagine how the ones we have today could be significantly better, at least in terms of how any further improvement would greatly benefit radio controlled flying models...

Can You Run Two Brushless Motors from a Single ESC?

Can You Run Two Brushless Motors from a Single ESC? - Airplanes and RocketsI am in the process of building a Douglas DC-3 control line model that uses a pair of ElectriFly Rimfire .10  motors, and wanted to know whether it would be possible to use a single electronic speed controller (ESC) for them. Unlike brushed DC motors with which you can - and I have in the past - gotten away with powering two motors from a single ESC, the brushless motors use a three-phase signal that is both amplitude and pulse width modulated. Such a waveform is not likely to be able to drive more than one motor properly, particularly given the motor's interaction with the ESC due to its time-variable complex impedance. I did a fairly extensive Internet search trying to find a definitive answer as to whether it can be done, but they were all just guesses. Many people seemed very knowledgeable on brushless motors and their controllers ...

Sig Balsa "Box of Blocks" - Making Large Blocks out of Small Blocks

Sig Balsa "Box of Blocks" - Making Large Blocks out of Small Blocks - Airplanes and RocketsThe cost of balsa, like everything else, has been rising significantly since the COVID-19 "plandemic" hit the world a couple years ago. Along with it the price of manufactured kits has gone up as well. A simple 1/16" x 3" sheet of balsa now costs around $2.00 (Sig price). In 2019, you could get it for $1.13 per the stored page at Archive.org. That's a 77% increase. Being a scratch builder of model airplanes, I frequently watch e-Bay, RC Universe, RC Groups, etc., for bargains on balsa, but they're getting harder to come by. If you have to order a balsa block online, there is a good chance it will end up being more dense (i.e., harder and heavier) than desired. Since local hobby shops (LHS's) are very rare these days, there is seldom an opportunity to go in and look for a suitable block prior to purchasing...

Russian Mosca I-16 Fighter

Russian Mosca I-16 Fighter, February 1942 Flying Aces - Airplanes and RocketsThis Russian Mosca I-16 fighter airplane bears some resemblance the Bee Gee series of American racers. According to the Wikipedia entry, "The Polikarpov I−16 (Russian: Поликарпов И-16) was a Soviet single-engine single-seat fighter aircraft of revolutionary design; it was the world's first low-wing cantilever monoplane fighter with retractable landing gear to attain operational status and as such 'introduced a new vogue in fighter design.' The I-16 was introduced in the mid-1930s and formed the backbone of the Soviet Air Force at the beginning of World War II. The diminutive fighter, nicknamed 'Ishak' or 'Ishachok' ('Donkey' or 'Burro') by Soviet pilots, figured prominently in the Second Sino-Japanese War, the Battle of Khalkhin Gol and the Spanish Civil War - where it was called the Rata ('Rat') or Mosca ('Fly')." Its maiden flight occurred ...

Macchi-Castoldia C/L Scale Schneider Cup Racer

Macchi-Castoldia Control Line Flying Scale Schneider Cup Racer, Annual 1958 Air Trails - Airplanes and RocketsThere are not too many control line float planes around for good reason. Unless you have an amphibious plane that can take off and land on water or a hard surface, it is hard to find a place where you can stand in the water far enough from shore to ensure a compete flight circumference of water. In most cases the water would be pretty deep. Even waist depth water can make turning difficult. A sandbar would be ideal, or maybe you are fortunate enough to have access to a shallow pond (natural or manmade). This Macchi-Castoldia Schneider Cup Racer C/L model fits the bill as an amphibious plane if you build the wheeled dolly included on the plans by Paul Palanek. the article and plans appeared in the Air Trails 1958 Annual edition...

Saturday Evening Post Comics by Charles Schulz

Saturday Evening Post Comics by Charles Schulz - Airplanes and RocketsThe Peanuts© comic strip, drawn by Charles Schulz, has been my lifetime favorite. That it is also the world's favorite strip is no wonder. Now that I have crossed the half-century threshold, I tend to look back at the innocence and complexity of the themes with a perspective other than simply entertainment - although I still thoroughly enjoy reading them just to get a few good laughs. Since Charles Schulz's death in 2000, books have been published documenting his life and how his experiences influenced Peanuts characters' appearances and behaviors. It is apparent from the content that Mr. Schulz hearkened from an era much different from today. It is hard to imagine a start-up comic akin to Peanuts being accepted in the much cruder, meaner, and less polite world of 2009. One interesting tidbit that I found in Peanuts: The Art of Charles M. Schulz, is a list of the edition of The Saturday Evening Post where Schulz's first for-pay comics appeared...

Buhl Bull Pup Article & Plans

Buhl Bull Pup, October 1950 Air Trails - Airplanes and RocketsBuhl Aircraft Company, founded in 1925 in Detroit, Michigan, really had just two successful airplane designs - the CA−6 Airsedan and the LA−1 Bull Pup. The Buhl A−1 Autogyro was a novelty aircraft that never gained popularity. It came out in 1931, a year before the company went out of business. This 1/2A size Bull Pup construction by Charles Hollinger article and plans appeared in a 1950 issue of Air Trails magazine. The Bull Pup began life as a rubber powered model, and Mr. Hollinger adapted it for powered free flight at a request from Air Trails editors. Its 35" wingspan is a convenient size and makes for an economical building project, even more so with today's balsa prices. A conversion to electric power with three-channel R/C would be easily accomplished...

Thermal-G R/C Club Fly-In, Summer 2010

Thermal-G R/C Club Fly-In, Summer 2010 - Airplanes and RocketsThe Thermal-G R/C Club held its annual summer fly-in on August 15, 2010, at the Erie Tech Center. The day was sunny (a little too warm for me) and quite windy. Because of the wind, most models were grounded, but a few brave souls did some flying, including quite a bit of 3-D stuff. I always get nervous seeing that stuff done so close to the pit area - especially in high wind - but at least up to the point that Melanie and I left, there had been no incidents. Also present were members of the Bean Hill Flyers control line club. Here are a few pictures I took of the flight line...

Flyin' Jenny Comic Strip - December 14, 1941

Flyin' Jenny Comic Strips: December 14, 1941 Baltimore Morning Sun - Airplanes and RocketsThe Baltimore Sun newspaper, published not far from where I grew up near Annapolis, Maryland, carried Flyin' Jenny from the late 1930s until the strip ended in the mid 1940s, so I saved a couple dozen from there. The first one I downloaded has a publication date of December 7, 1941 - that date "which will live in infamy," per President Roosevelt. Many Americans were receiving word over the radio of the Japanese attack on Pearl Harbor while reading this comic at the breakfast table ...

Mathematical Puzzles, 1986 Old Farmer's Almanac

Mathematical Puzzles, 1986 Old Farmer's Almanac - RF CafeI finally got around to scanning selected content from the 1986 issue of The Old Farmer's Almanac. The "Old and New Mathematical Puzzles" feature was always my favorite, so that's what is posted first. Difficulty levels are assigned as 1 for the easiest to 5 for the hardest. Solutions are provided for levels 1 through 4, but level 5 (problems 12 through 15) problems were to be mailed in (no e-mail in the day) to vie for a cash prize for providing the "best set of solutions," though I don't know how one solution to these problems can be deemed "better" than another. Problem #5 is interesting in that you must assign a value for the various numerical prefixes and quantities. Sure, we all know what "atto" and "score" are, but what about "crore" and "myriad?"

Our First Moon Scout Heads for the Pad, February 1965 Popular Mechanics - Airplanes and RocketsSurveyor 1, the first in a series of seven, launched from Cape Canaveral on May 30, 1966 and landed on the moon at Oceanus Procellarum on June 2, 1966. As the name implies, its mission was to analyze and map the lunar surface in preparation for manned landings there at the end of the decade. As detailed in this 1965 Popular Mechanics magazine article, Surveyor 1 was equipped with many instruments and tools for photographing, measuring, and testing the moon's features and composition. Prior to its visit, nobody was certain whether the lunar surface was covered with a thick layer of dust that would envelope a craft and render a manned visit impossible. Turns out, the dust layer was quite thin. Even so, there was still some concern prior to Apollo 11's landing, because conditions might vary...

Phantom P-30 Motor

Phantom P-30 Motor, October 1941 Flying Aces - Airplanes and RocketsLittle did most people know that two months after this October 1941 issue of Flying Aces magazine arrived in their mailboxes, the U.S. would be drawn into what would become World War II, following the bombing of Pearl Harbor by the Japanese on December 7, 1941. Flying Aces was chock full of factual and fictional stories about the last war (War War I), and the things the Krauts and Nips were already pulling across Western Europe, North Africa, China, and the South Pacific. Much more subject material was near at hand. Oddly, the magazine changed its theme and title to Flying Age shortly before the end of WWII, electing to focus more on full-scale aircraft rather than models. According to the Bureau of Labor Statistics' Inflation Calculator, the $9.75 Phantom P-30 engine would cost you about $194 in 2023. In 2020 it would have been $163. That means the total rate of inflation for the last three (3) years has been around 19% (~6.3%/year). In 2016 the equivalent price would have been about $153, so from 2016 to 2020 the increase was just 6.5% for the entire four years (~1.6%/year)...

Candid Camera at the 1959 NATS

Candid Camera at the NATS (September 1959 Model Aviation News Bulletin) - Airplanes and RocketsHere are a few more photos from the 1959 AMA Nationals, in continuation of coverage in the July and August issues of Model Aviation magazine. Some are behind-the-scenes shots rather than just flight line action. Vintage unbuilt kits of a lot of the airplanes you see in these pictures are selling for a small fortune today on eBay. BTW, this series of Model Aviation is completely different than and precedes the current incarnation of Model Aviation that followed the American Aircraft Modeler and American Modeler titles. Its size is just 8½" high by 5½" wide, and were typically only about 20 pages. The February 1959 issue has about twice as many pages because it also contains the 1950-1960 "Official Model Aircraft Regulations Governing Sporting Model Aviation in America." I have all 12 issue from 1959, and don't know if others are available...

Signed, Comet F−86D Sabre Jet Kit

Signed, Comet F-86D Sabre Jet Kit - Airplanes and RocketsThis is not just another vintage Comet Model Hobbycraft, Inc., F−86D Sabre Jet from 1952. What makes this kit unique is that it has the signature of well-known (at the time) Comet draftsman Gerald J. Blumenthal on the box cover. John Zawiski was the designer. The f-86D Saber has a wingspan of 13-1/4" and a length of 15-1/16". The model was meant to be flown either as a free flight glider or attached to a tether line where the pilot drags it around in a circle. A few of these have sold recently on eBay for around $20-$30, so they can still be found. This particular kit, provided by Mr. Steven Krick, is going to be offered as a donation to the AMA's National Model Aviation Museum in Muncie, Indiana, because of the signature ...

Swedish Saab J 21 Fighter

Swedish Saab J 21 Fighter, February 1971 American Aircraft Modeler - Airplanes and RocketsDon Berliner, who published many articles and even books on scale model and full-sized aircraft, provided this article on the SAAB J 21 fighter in a 1971 issue of American Aircraft Modeler magazine. Most people nowadays associate the company name SAAB with high quality automobiles, although Saab the car company went defunct in 2012. From the World War II era through to today, they produce(d) aircraft. Here is an excerpt from their current "About Us" webpage; "When Saab was founded in 1937, our primary aim was to provide military aircraft for Sweden. Today, we serve the global market with world-leading products, services and solutions from military defence to civil security. With operations on every continent, Saab continuously develops, adapts and improves new technology to meet customers' changing needs." The SAAB J 21 went through multiple design iterations as both a pusher-prop and a jet fighter aircraft...

Northrop Gamma - The Plane That Had It All

Northrop Gamma - The Plane That Had It All, March 1971 American Aircraft Modeler - Airplanes and RocketsThe Northrop Gamma was as close to a one-size-fits-all aircraft as you would come by in the mid 1930's. It is pretty incredible to ponder the rapid development in aircraft and engines in the short three decades since the Wright brothers made their world's first powered flight in 1903. Airspeeds went from 30 miles per hour to more than 200 miles per hour. Engines went from 12 horsepower to nearly 1,000 horsepower in that timespan. The Northrop Gamma appeared in more than a dozen different versions including an air racer, a military bomber, a trainer, a high altitude weather research platform, a military attack airplane, and a seaplane. It was one of the first production designs to incorporate a completely enclosed cockpit - a welcome feature to pilots in cold weather ...

Find the Scale Wingspan & Area

Find the Scale Wingspan & Area - June 1969 American Aircraft Modeler - Airplanes and RocketsDave Platt - aka "Mr. Scale" - is one of the world's most accomplished scale model airplane builders and flyers. He somehow manages to turn out magnificently detailed scale models year after year. If you haven't seen his "Platt's Laws of Scale Modeling," derived from his decades of experience, you'll want to do so. He has built and flown his scale models in the realms of free flight, control line, and radio control, using internal combustion engines with propellers, ducted fans, and turbine jets for propulsion. There might be someone somewhere equally qualified to comment on scale airplane modeling, but none more qualified. When this "Find the Scale Wingspan & Area" article appeared in a 1969 issue of American Aircraft Modeler magazine, slide rules were the de rigueur...

Peacetime Uses for V2 Rocket, by Arthur C. Clarke

Peacetime Uses for V2 Rocket, by Arthur C. Clarke - RF CafeThis article by science fiction writer Arthur C. Clarke, of 2001: A Space Odyssey fame, suggested the use of surplus German V−2 (Vergeltungswaffe 2; i.e., Retribution Weapon 2) rockets for launching scientific payloads into space rather than for launching terrorizing attacks on European cities. The October 1945 publishing date was after Germany had surrendered in the spring of that year and Allied forces were rounding up war criminals and confiscating documents and equipment. Clarke describes how an "artificial satellite" could be caused to circle the earth "perpetually" and was published in the October 1945 edition of Wireless World magazine. The pilot-less V−2, along with the V−1 "Buzz Bomb," were launched from within Germany and caused massive structural damage and human death and suffering. For war progenitor and aggressor, Germany, to call it a retribution weapon was a gross misnomer, especially considering it was the second time (WWI and WWII) in three decades that the country had attempted to bring Europe under its dominance with brutal assaults...

Blohm Voss 141-B Article & Plans

Blohm Voss 141-B Article & Plans, August 1970, American Aircraft Modeler - Airplanes and RocketsAirplanes and Rockets website visitor Lieven M. requested that this article on the Blohm Voss 141-B (BV 141-B) be scanned and posted from the August 1970 edition of American Aircraft Modeler magazine. The BV 141-B, designed by Mr. Terry Aldrich, is a unique scale subject in that it is a World War II German fighter-bomber featuring an asymmetrical configuration. It looks sort of like a P-38 Lightning with the right boom missing. The engine in on the left at the nose end of the single fuselage boom, and the pilot compartment is on the right, on the wing. The horizontal stabilizer span is about 80% to the left of the vertical fin, and 20% to the right of it. Construction uses sheet balsa for the wings, tail surfaces, and profile fuselage. Power is provided by a single 049 engine...
