The Boom in R/C Boats

The Boom in R/C Boats, June 1955 Popular Electronics - Airplanes and RocketsThis article entitled "The Boom in R/C Boats" appeared in the June 1955 edition of Popular Electronics magazine which, during the early years of its existence devoted quite a bit of print space to radio control airplanes, boats and cars. As with all things electronics, a huge surge in consumer interest was occurring with over-the-air communications. Bill (William) Winter served as the editor of the Academy of Model Aeronautics' (AMA's) American Modeler and American Aircraft Modeler magazines from 1966 through 1974, but his efforts to promote all form of modeling - airplanes, helicopters, cars, boats, trains, and rockets - covered many decades. His first recorded article, "Building the Famous Udet Flamingo," (co-authored by Walter McBride), was published in the March 1935 issue of Universal Model Airplane News magazine...

More... About Stunt Theory

More... About Stunt Theory, March 1957 Model Airplane News - Airplanes and RocketsIt would be interesting to do a side-by-side comparison on what was considered engineered control line stunt model airplane design in 1957, when this article was written, to what is today considered to be optimal design criteria. I am trying to get back into control line stunt flying and have one model built currently, the Enterprise-E. It has been flown a few times and is (was) extremely sensitive on the controls when set up per the plans. A little bit of control handle movements resulted in a huge amount of both elevator and flap deflection. Fortunately, access to the flap control horn is available through the removable top fuselage hatch, so I was able to relocate the pushrod from the bellcrank to the flap horn, and then from the flap horn...

Lite-Brite by Hasbro

Lite-Brite by Hasbro - Airplanes and RocketsWhen Melanie and I got married in 1983, part of her dowry included some of the toys she had as a little girl. A Hasbro Lite-Brite was one of them. Our kids played with it when they were young, but somewhere along the line during our many household moves, it disappeared. We probably donated it to the Salvation Army at some point - a lot of our stuff has ended up there. About a month ago we started watching for a good one on eBay that didn't cost too much. Finally, there was a 1967-vintage Lite-Brite in like-new condition up for auction that we got for around $45. It has a nice box...

Wild Bill Netzeband's Control Line Capers

Wild Bill Netzeband's Control Line Capers, October 1961 American Modeler - Airplanes and RocketsPer "Wild Bill" Netzenband's report in this 1961 issue of American Modeler magazine covered the Vancouver Bi-Liners, MAC highlights, Alan Nichols' success in Thompson Trophy Racer events, encouraging clubs to adopt the affordable, and slow-flying contests. He addresses backlogged club crest submissions, noting the impracticality of featuring all due to volume. Alan Nichols debunks the myth that models wear out quickly, citing his year-old Nobler and a five-year-old Fierce Arrow with original engine. Memories resurface of McDonnell Aircraft's picnic air shows, where Phil Hamm's reliable metal jet stood out. Southern California's new Control-Line Association, led by John Gudvangan and others, seeks enthusiasts. Detroit's Metropolitan Speed Association unveils an $8,000 Rouge Park speed circle, aiming for a competitive...

Pilots Matter in Age of Autonomous Planes

Why Pilots Matter in Age of Autonomous Planes - Airplanes and RocketsThis article entitled "Why Pilots Will Matter in the Age of Autonomous Planes" appeared in the June 2025 issue of IEEE's Spectrum magazine. "Long after planes start flying themselves, humans will still be in the loop. In August 2001, an anonymous guest posted on the forum at Airliners.net, a popular aviation website. 'How Long Will Pilots Be Needed?' they wondered, observing that '20 years or so down the road' technology could be so advanced that planes would fly themselves. 'So would it really be useful for a person to go to college now and be an airline pilot if a few years down the road they will be phased out by technology?' Twenty-four years later, the basic technology required to make aircraft fly themselves exists, as evidenced by the fact that most commercial flights are flown largely on autopilot..."

Flyin' Jenny Comic Strip: February 8, 1942

Flyin' Jenny Comic Strips: February 8, 1942 Baltimore Morning Sun - Airplanes and RocketsThis is the February 8, 1942, "Flyin' Jenny" comic strip. The 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. I expect that soon there will be World War II themes. "Flyin' Jenny," whose real name was Virginia Dare (what's in a name?), was a test pilot for Starcraft Aviation Factory who divided her time between wringing out new airplane designs and chasing bad guys. She was the creation of artist and storyteller Russell Keaton...

Peanuts Skediddler Collection

Peanuts Skediddlers Collection - Airplanes and RocketsThis is the complete set of Peanuts Skediddlers, sold by Mattel. Linus is extremely difficult to find, and when you do, he typically sells for $200 or more. If you find a Linus Skediddler with the original box, expect to pay $400. Over time, our (Melanie and me) Peanuts collection of memorabilia has grow from the few items she had left over from her girlhood to complete sets. Everything was gotten via eBay auctions. It took a lot of patience to be able to get good quality items at an affordable price. Here is a bit of history I gathered on the Skediddlers. Phenomenon: In the mid-to-late 1960s, Mattel capitalized on the explosive popularity of Charles M. Schulz's Peanuts comic strip by releasing the Skediddler - a line of friction-powered toys. Unlike wind-up mechanisms, these toys relied on a simple push-and-go design: sliding them across a surface activated internal gears, causing the characters' limbs and heads to jerk in a whimsical "skedaddling"...

The Reds Aren't Stallin'!

The Reds Aren't Stallin'!, February 1949 Air Trails - Airplanes and RocketsThis 1949 Air Trails magazine article warns that the Soviet Union has surpassed the U.S. in military aircraft production by a 15-to-1 margin, with advanced jet fighters, bombers, and long-range piston-engine planes already operational. Soviet scientists have also conducted atomic tests and are close to producing compact A-bombs. Intelligence reveals a Red Air Force of 15,000 first-line aircraft, including 2,400 jets, some surpassing American designs. The Soviets broke the sound barrier before the U.S. and have developed powerful turbojet engines, some with innovative features like variable-pitch stators. German scientists and captured technology accelerated Soviet progress, particularly in rocketry and jet propulsion. Their aircraft feature advanced construction techniques, such as metal-plywood sandwich wings, and superior armament...

Glider Winch Construction Article

American Aircraft Modeler Glider Winch Construction Article (April 1973 American Aircraft Modeler) - Airplanes and RocketsA long time ago (circa 1977) I bought a used glider winch at an auction held by the Prince Georges Radio Club, in Maryland. It cost me somewhere around $25, which was a lot for me in the mid 1970s. The motor and control circuitry was contained in a plywood box, with a jack for the foot switch and terminals to clamp jumper cable to from a car. In looking at these plans for the AAM Glider Winch shown here from the April 1973 American Aircraft Modeler, it looks a lot like mine, only mine was in a wooden box. It worked extremely well for my 99" Windfree and 99" Aquila sailplanes. Unfortunately, I sold it shortly after getting married in 1983 (couldn't eat the winch). I would love to have it back. Actually, what I would rather have at this point is a winch that is powered by a cordless drill that would be lighter...

Weather Surveillance by Satellite

Weather Surveillance by Satellite, March 1967 Electronics World - Airplanes and RocketsWe take for granted most of the technology that surrounds us. Unless you were alive 60 years ago at the dawn of microelectronics and space flight, it would be difficult to imagine a world without cellphones, desktop computers, color TVs, the Internet, and even satellite-base weather forecasting. Everyone likes to make jokes about weathermen being no better at predicting the weather than your grandmother's roomatiz[sic], but the fact is that, especially for short-term (2-3 days) predictions, we get pretty good information. As a model airplane flyer, I check the wind level forecast nearly every day to see whether my model plane can handle it. AccuWeather's free hourly forecast is usually pretty darn accurate for today's and tomorrow's wind...

Phineas Pinkham: Smoke Scream

Phineas Pinkham: Smoke Scream, March 1937 Flying Aces - Airplanes and RocketsIn this 1937 "Smoke Scream" in a 1937 issue of Flying Aces magazine, by Joe Archibald, Lt. Phineas Pinkham, the 9th Pursuit Squadron's resident troublemaker, stumbles into chaos when he encounters an elephant named Hungha Tin and its Hindu mahout. After the elephant drinks a bottle of arnica meant for a local's backache, it goes berserk, wreaking havoc across the Allied camp. Meanwhile, Brigadier Scruggs confesses to Pinkham that he sleepwalked and handed top-secret battle plans to an unknown spy. Pinkham, framed by the mahout - who's actually a German agent - unknowingly smokes a drugged cigarette and nearly flies a stolen Spad to the enemy. The vengeful elephant interrupts his forced defection, allowing Pinkham to escape with Hauptmann von Spieler as his prisoner. Back at base, Pinkham...

Control-Line Aerodynamics Made Painless

Control-Line Aerodynamics Made Painless, December 1967 American Modeler - Airplanes and RocketsThe Academy of Model Aeronautics is granted tax-exempt status because part of its charter is for activity as an educational organization. I think as time goes on, it gets harder for the AMA for fulfill that part of its mission because presenting anything even vaguely resembling mathematics or science to kids (or to most adults for that matter), is the kiss of death for gaining or retaining interest. This article, "Control-Line Aerodynamics Made Painless," was printed in the December 1967 edition of American Modeler magazine, when graphs, charts, and equations were not eschewed by modelers. It is awesome. On rare occasions a similar type article will appear nowadays in Model Aviation magazine for topics like basic aerodynamics and battery / motor parameters. Nowadays, it seems, the most rigorous classroom material that the AMA can manage to slip into schools is a box of gliders and a PowerPoint presentation...

Aeronautical Antiques

Aeronautical Antiques, from April 1957 American Modeler - Airplanes and RocketsPeter Bowers first became know to me because of his Fly Baby homebuilt airplane. It won the Experimental Aircraft Association (EAA) design contest in 1962. Back in the middle and late 1970s, I was taking flying lessons and dreaming big about building my own aerobatic biplane. Being an avid woodworker, the Fly Baby appealed to me because it was constructed entirely of wood, except for a few critical metal fittings. My plan was to build the biplane version of the Fly Baby. Like so many other things, the aeroplane never got built. Peter Bowers was not only an aeronautical engineer and airplane designer but also an aviation historian and model airplane enthusiast...

FlightGear Open Source (Free) Flight Simulator

FlightGear Open Source Flight Simulator - Airplanes and Rockets"FlightGear" is an Open Source (aka Free) flight simulator program which I first wrote about in 2012. It has come a long way - and was pretty dran good, aven back then - and is now a viable competitor for Microsoft's Flight Simulator (MSFS). The leatest release as of this writing is 2024.1.1. The graphics are superb and easily on par with MSFS. FlightGear has a joystick interface, but I don't own a joystick, so my experience with it using keyboard inputs. VR headsets are also supported now. The basic download comes with a couple dozen aircraft, and there are many additional models available as separate downloads. FlightGear runs on Windows, macOS and Linux. Thanks to all the folks who have spent their valuable time developing FlightGear! FlightGear website: "FlightGear is an open-source flight simulator. It supports a variety of popular platforms (Windows, Mac, Linux, etc.) and is developed by skilled volunteers from around the world...

Sketchbook, October 1950 Air Trails

Sketchbook, October 1950 Air Trails - Airplanes and RocketsThe October 1950 Air Trails magazine showcases modelers' innovations, including H.G. Oliver's Plexiglas skids for speed models and Don Nelson's booster battery setup. Ray Biernacki suggests keeping brushes soft with thinner fumes, while Richard Larson offers a footswitch for bench testing. Ted Jones improves dethermalizer safety, and Charles Francis simplifies its design. Willard Hafler's flying wing excels in speed and sport flying, and Leon Shulman repurposes a crankcase recess as a fuel tank. The magazine encourages readers to submit their own ideas, paying $2 per accepted sketch. These practical, cost-saving solutions highlight the creativity of mid-century model aviation enthusiasts, blending engineering ingenuity with accessible materials - a snapshot of hobbyist innovation in postwar America...

Bertrand Piccard's Big Hydrogen Adventure

Bertrand Piccard's Big Hydrogen Adventure - Airplanes and Rockets"IEEE Spectrum interviewed Bertrand Piccard at a pivotal moment in the hydrogen-powered aircraft project, with the plane, called Climate Impulse, about 40 percent built. Piccard spoke about the contributions of his corporate sponsors, including Airbus, to the Climate Impulse project and about why he's confident that hydrogen will eventually succeed as an aviation fuel. He'll fly around the world in a hydrogen fuel-cell aircraft. Few explorers have reached the heights, literally and figuratively, that Bertrand Piccard has. He is the quintessential modern explorer, for whom every big mission has a purpose, which generally boils down to environmental and climate-change awareness. In 1999, he was the first person to circumnavigate..."

Iron Curtain Engines - Da? Nyet?

Iron Curtain Engines - Da? Nyet? from August 1962 American Modeler Magazine - Airplanes and RocketsAmazingly, even during the Cold War years it was not uncommon to see aircraft modelers from the "Iron Curtain" countries participating in international contests. Even Commies like flying model airplanes. Because their societies and politics were so closed and guarded, getting information about their modeling supplies was darn near impossible except during events where inspection could be made. Being a generally friendly bunch of guys, the modelers would share their designs with the Free World, and vice versa. Then, in subsequent years the Commies would show up with equipment that was exact replicas of ours - copyrights and trademarks held no legal weight behind the Iron Curtain. Truth be know, most or all of the participants were probably KGB agents (or other Commie country equivalents) engaging...

How to Make Scale-Model Planes for Government Use

How to Make Scale-Model Planes for Government Use, May 1942 Popular Science - Airplanes and RocketsWith the entry of the United States into World War II came the need for service members to be trained on many new technologies - among them being airplanes and the ability to identify them quickly. Electronics technicians and airframe and powerplant mechanics were in need, of course, but everyone had to be able to tell friend from foe when airplanes were approaching. In order to assist the war effort, a call went out to civilians to begin producing thousands of models at a 1:72 scale so that at 35 feet away they appeared in size to be that of a full-scale version at about half a mile. Detailed paint jobs were not required - only that the profile from all angles look exactly like the real thing. In fact, the models were painted flat black so as to look like a distant airplane against the background sky. Both Allied and Axis airplane models were needed so that soldiers and sailors could quickly spot a potential danger and decide whether to take cover and prepare to fight, or to continue with business as usual. This article appeared in the May 1942 edition of Popular Science, meaning that it was probably written sometime around February, only a few months after the Japanese attacked our naval base at Pearl Harbor, Hawaii, on December 7, 1941...

Radio Control: How to Get an F.C.C. License

Radio Control How to Get F.C.C. License, from September 1962 American Modeler Magazine - Airplanes and RocketsIf you have only ever known a time in the R/C era when 2.4 GHz, spread spectrum radios were in use and not only were there no interference issues, but there were no licenses required, either, for legal operation, then it might be hard to imagine when this was not so. Most people in the R/C realm at least remember the 72 MHz frequency band where each system operated on a specific center frequency, where no two systems could be operated in the same vicinity. Before that there was the 27 MHz band, which is where I began, more specifically on 27.195 MHz. Only five frequencies were reserved by the FCC exclusively for radio control use. That meant never more than five planes in the air, or even being worked on with the radio on, at a time. The band was part of the original Citizens Band (CB) radio allocation. Commercial CB radios were notoriously lousy at controlling bandwidth and often overlapped the R/C bands with enough power to cause deadly (to a model) interference. My FCC operator's permits (Class C and Class D), obtained sometime around 1972, is long gone...

Sears Electric Hair Clipper Set

Sears Electric Hair Clipper Set 7934 - Airplanes and RocketsIn my zeal to procure some of the items I remember having or using as a kid in the 1960s and '70s, along with some of the things Melanie and I had when we first got married back in 1983, I ran across this Sears Electric Clipper Set (#7934) on eBay. The seller was only asking about $10 for it, so here it is. As you can see in the photos, it is in mint condition, and even the original box shows only minor wear and tear from sitting in someone's closet for more than half a century. I disassembled the clippers and did a thorough cleaning (not much there) and oiled the moving parts with a bit of 3-in-1. Everything seems to be in great condition. Even the power cord is supple and unscathed. One of the plastic blade attachments was included, although the instruction sheet shows four types. Judging from other similar clippers for sale on eBay, the set only came with one, and the other styles must have been available for purchase separately. If you have any you can bear to part with, please let me know...

Control Line Wind Flying

Wind Flying - September 1972 American Aircraft Modeler - Airplanes and RocketsAirplanes and Rockets website visitor Lars B. wrote from Sweden requesting that I scan this "Wind Flying" article from the September 1972 edition of American Aircraft Modeler magazine. It describes a method for replacing engines and motors with human power for preforming some pretty impressive C/L aerobatics on windy days. Basically, you drag the model airplane around on its control lines, which often required not just turning in a circle while standing in one place, but walking around a small circle in order to get more speed. If there is any wind, you need to put extra effort into the pulling when moving into the wind. I can remember doing this as a teenager, only I did it with the engine in place but not running - usually because I could not afford to buy enough fuel to fly as often as preferred...

Lew McFarland's Shark "45"

National Champion Lew McFarland's Shark "45", October 1961 American Modeler - Airplanes and RocketsThe Jetco Shark 15 was my very first built up control line airplane. Before that they had all been plastic Cox models. As did many kids in the 1960's and 1970's I learned to fly on a Cox PT−19 Trainer (summer of 1969, about the time Apollo 11 landed on the moon). Before building the Shark 15, my experience with built-up models was with rubber-powered free flight. Mustering enough money for a Shark 15, a Fox 15 C/L engine, and covering materials was not easy in those days. The Shark 15 flew very nicely when I could get the Fox 15 started and running properly. Loops, wingovers, and inverted flight were much more satisfying than with the Cox models, whose .049 engines had a nasty habit of quitting during inverted flight. I resolved to someday step up to a Shark 45 once I had enough spare cash, but to this day I still have never owned one. The largest engine I've ever had on a C/L model was a Fox 35 (equally temperamental and frustrating) on a Sterling Ringmaster...

Scale Model Instrument Panels for IFR

Instrument Panels for Instrument flight Rules (IFR) - Airplanes and RocketsIt is hard to imagine how pilots managed to find their way through fog, rain, sleet, and snow prior to the advent of instruments that could indicate whether the airplane was flying straight and level or spiraling toward the ground. Some flyers were good enough in most situations to sense attitude even without an outside-the-cockpit visual clue. However, it is entirely possible to enter into a situation where your senses cannot possibly tell the difference between normal flight and a life threatening scenario. Albert Einstein's General Theory of Relativity tells us that without knowing otherwise, there is no discernable difference between gravity and physical acceleration. Therefore, a pilot in solid Instrument Flight Rules (IFR) conditions where he cannot see the sky or ground could very well mistake ...

Blade 230 S SMART Flight Video

Blade 230 S SMART Flight Video - Airplanes and RocketsI just made a short video of my Blade 230 S SMART helicopter in flight to demonstrate how easy it is to fly in the Stability Mode (I've not tried to fly in the Agility Mode). Easy, that is, after a trial−and−error method of programming the Spektrum DX6 G3 transmitter. The setting shown in the user's manual leaves the heli way too unstable IMHO. In order to make it trainer-like, I cranked the servo throws back to 50% (default 100) and turned up the GER setting to 150 (100 default). Also in Forward Programming I set the Stability to 150 (its highest setting). After that, she hovers hands−off when there's no wind. I had Blade 230 S V2 prior to this (sold it), and it flew fine in Stability Mode using the manual's settings, so something's different with the SAFE version. I was about to give up on flying it until I made the setting adjustments. I might be willing to sell the heli w/training gear, two 850 mAh Smart batteries and Smart Charger (w/IC2−IC3 adapter) for $310 (+shipping) if you're interested. Tx not included.

Days of the Americans

Days of the Americans, December 1945 Flying Age Including Flying Aces - Airplanes and Rockets"Days of the Americans" is one chapter out of a book entitled "The Big Distance." Per this article which appeared in the December 1945 issue of Flying Age magazine, "The Big Distance, the official story prepared by the AAF, is to the struggle in the Pacific what Germany was to the European phase of the war." Unlike the European Theater of World War II, much of the populations of South Pacific islands were inhabited by people who were barely out of the Stone Age in terms of cultural and scientific evolution. The arrival of Northern hemisphere Western and European Anglo Saxons brought a culture of sophistication never dreamed of by the backwards civilizations indigenous to the islands. That was a common theme of the villages visited by the McHale's Navy crew in the 1960s TV series. While reading the story, I was a bit taken aback by the narrative of Americans having come to the island paradises and bringing their gigantic machines and inexplicable habits, but then the author states, "There always will be a faction among the elders who will attempt to establish the basic facts of the legend of the Americans through use of pure logic, simply pointing out that if the Americans had not been there, the Japs still would be. If the Americans weren't actually present, the question will be posed...

Build the S.S.P. Helicopter

S.S.P. Helicopter from the August 1972 American Aircraft Modeler - Airplanes and RocketsImagine if your path to flying an R/C helicopter involved first designing, then building, and then troubleshooting the contraption. That was the burden of pioneers. We have people like S.S.P. Helicopter designer Gene Rock to thank for being able to enjoy the state-of-the-art models that are available today. This article from the August 1972 edition of American Aircraft Modeler magazine describes the process of machining all the metal parts for an Enya .45-powered craft. Mr. Rock even designed a very successful mechanical gyro for keeping the tail under control. If you have ever tried flying an R/C heli without any type of gyro (I have, on a DuBro Tristar), you will fully appreciate what a pleasure it is to not have to manually counter torque changes (throttle) with tail rotor stick input from the transmitter. Around 2008 I bought a Blade MCX2 coaxial rotor helicopter for flying inside, and the gyro is so good on that thing that you can put it in a full speed pirouette...

"Flying Platform" Gets Three Engines

"Flying Platform" Gets Three Engines, May 1957 American Modeler Magazine - Airplanes and RocketsA lot of wild and zany ideas for flying machines have been tried over the years. Most, if not all, of them could probably be coaxed into flying with modern computer-controlled stabilization and navigations systems that use fast-reacting powerplants, sensitive accelerometers and position sensors. For anything other than stable platforms, human pilots just could not provide control - at least on an extended basis and under adverse weather conditions. This "flying platform" by Hiller Helicopters is one such example. It appeared in the May 1957 issue of American Modeler magazine. Piloting it was essentially the same as with the Lunar Lander...

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)...

Radio Controlled Flight

Radio Controlled Flight, January 1947 Radio News - RF CafeEven though the U.S. Army Air Force and other research agencies around the world were at the forefront of experimenting with remote control airplanes, helicopters, tanks, trucks, cars, boats, and rockets, hobbyists were forging their own paths in the electronic art. I did not know until reading this article that drones were flown through the radiation field at the Bikini Atoll atom bomb test site for data collection. In fact amateur radio operators have long had the privilege of broadcasting for the purpose of remotely controlling a vehicle - the only scenario of Earth-based transmission whereby the "control operator" is not required to identify his/her call sign at an interval prescribed by the FCC (currently at least once every 10 minutes and at the end of the broadcast). Vintage modeling magazines have articles on early radio controlled (R/C) airplane experimentation. Target drones subject to remote control were not just small models, but also full-size aircraft that were deemed not airworthy enough to carry a human crew...

Robot Helicopter

Robot Helicopter, November 1956 Popular Electronics - Airplanes and RocketsThis angled, twin rotor, no-tail-rotor (NOTAR) configuration for a remotely controlled helicopter was pioneered by Kaman Aircraft Corporation in the 1950s, and is still a unique part of their product lineup today. Per their website, "The Unmanned Aerial Truck (UAT) continues a Kaman tradition of pioneering unmanned helicopters. In 1957, Charles Kaman, founder of Kaman Corporation, created the first pilotless aircraft." The embedded video below is a 1957 edition of the "You Asked for It" television show, where host Jack Smith reported on a demonstration of the craft. It is amazingly stable and easy to fly, by a pilot in the cockpit, from a ground-based remote control station, or from a remote control unit located in another airborne helicopter. As you will see, this probably qualifies as the first practical first-person-view (FPV) remote controlled aircraft...

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?"

For the Tenderfoot: Bonanza and Mustang

For the Tenderfoot: Bonanza and Mustang Article & Plans, January 1971 American Aircraft Modeler - Airplanes and RocketsWebsite visitor Kenneth E. wrote to say that he is working to build a complete collection of the Tenderfoot models that were published in the Academy of Model Aeronautics' American Aircraft Modeler magazine. The Tenderfoot series was an attempt to provide motivation to young newcomers to the hobby. They were a mix of freeflight rubber powered airplanes and helicopters, gliders, and ¼A & ½A control line designs that built quickly, simply, and cheaply. Kenneth requested reprints of the following three models: the ½A C/L Saucerer from January 1970, the FF HLGs Bonanza and Mustang (this article) from January 1971, and the FF rubber Clodhopper from February 1973...

Tufnut Article & Plans

Tufnut Article & Plans, January 1955 Model Airplane News - Airplanes and RocketsThis Nufnut free flight model airplane article and plans came to being in response to laments from would-be model airplane builders who tried and failed at their first (and sometimes more) attempts to make and fly something even as simple as a rubber powered model. The author decided to present detailed instructions on building and covering an open frame stick and tissue model, being sure to detail areas that generally cause the most trouble. The most difficult task for most beginners is covering the airframe with tissue and then obtaining a warp-free structure after application of dope. If you are new to the hobby and either have experienced such disappointments or are considering getting into the fine hobby of model airplane building and flying and seek sage advice on how to avoid discouraging pitfalls, then you have come to the right place. Tufnut is a somewhat unique design with its solid balsa fuselage that has a slot cut in it for containing the rubber band, rather than just using a stick with the rubber hanging underneath...

A Day in the Life of a Hobby Dealer

A Day in the Life of a Hobby Dealer (November 1962 American Modeler) - Airplanes and RocketsIt's a good bet that many modelers, myself included, have dreamed about owning a hobby shop. How nice it would be to spend our days amongst walls, shelves, and display cases filled with every type of modeling kit and accessory. Melanie and I actually looked into buying one when we lived in Colorado Springs in the early 1990s. It's a good thing we didn't in retrospect, given the way the local hobby shop (LHS) has suffered tremendously since Internet-based purchases have become so popular - especially being tax-free in most areas. There are still big hobby shops left, but they are few and far between. I'm as guilty as the next guy for not doing more to support my LHS, but usually it's for convenience sake more so than price and not paying sales tax. This article from the November 1962 edition of American Modeler magazine, a time when local hobby shops were still the rule rather than the exception, is a humorous "day in the life of a hobby dealer." You can just imagine how plausible the scenario might be...
