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, 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 all the weight and bulk. Modern-day low-cost, readily available R/C models incorporate, depending on your requirements, autopilot, total prefabrication of airframe, propulsion, and guidance components. BTW, dig Mr. Bohnenblust's ride in that photo...

Antique Rope Bed with Sacking Bottom

Antique Rope Bed with Sacking Bottom - Airplanes and RocketsAfter dropping off some stuff at the Erie City Mission, Melanie and I walked through the display floor to see what was available. We've gotten some good things there in the past, including a Queen Anne chair and a china hutch. We've been looking for a used, full-size bed for the spare bedroom to replace the twin bed that used to be our daughter's. Fortunately, the Erie City Mission had recently acquired a turn-of-the-20th-century rope bed that, according to lore, used to belong to the owner of a defunct local brewery (Kohler?). Heavy pine is used for the entire framework. It was in fair shape, with expected dings and scratches from 100+ years of use. Rather than undertake a total restoration...

World's Largest Air-Model Contest

World's Largest Air-Model Contest, November 1961 American Modeler - Airplanes and RocketsThe 1961 Academy of Model Aeronautics' (AMA's) National Model Airplane Championships (aka "The Nats") were held that year at Willow Grove Naval Air Station just North of Philadelphia. The U.S. military was concerned with encouraging young men to excel in the field of aviation in order to help breed future pilots, mechanics, researchers, and other aerospace related careers within the Army, Air Force, Marines, and Navy. In fact, the U.S. Navy was a prime sponsor of the Nats for many years. In the early 1970s, geniuses in the Pentagon decided that such activity was no longer a good investment, so the AMA had to find other private and public venues for events. The AMA's flagship publication, American Modeler magazine, provided coverage...

Angstrom Eberenz, AMA 2024 C/L Champion

Angstrom Eberenz, AMA 2024 Control Line Junior Champion - RF CafeIf you have been around the Airplanes and Rockets website for a while, you are probably aware that my hobby activities have been funded by my profession in radio communications (see RFCafe.com). Reading this, you likely also know that each year the AMA holds national championships for all forms of model aviation including radio control, control, and free flight. Airplanes, helicopters, and theses day drones, are the primary focus, while rockets, cars, and boats are sometimes featured. Various classes of contents are conducted, including Expert and Standard, Senior and Junior, and others. What really caught my attention this year and last year was the first name of the champion for the Junior class of control line flying - Angstrom! Is that a great name or what? It sure beats Kirt. The name, of course, is a unit of wavelength named in honor of Anders Jonas Ångström. Here is the origin of Ebernez.

PHASA-35 Solar Stratospheric Trials

PHASA-35 Solar Aircraft Stratospheric Trials - Airplanes and Rockets"Designed to operate as a high-altitude, long-endurance surveillance and reconnaissance platform the aircraft - defined as a High Altitude Pseudo Satellite (HAPS) Uncrewed Aerial System (UAS) - has been designed by BAE Systems subsidiary Prismatic, a division of the company's FalconWorks advanced research and development arm. Alongside reconnaissance, the aircraft has the potential to be used in the delivery of communications networks including 4G and 5G and could be used in a wide range of applications, such as disaster relief and border protection, as a cost-effective alternative..."

Weather Hop

Weather Hop (July 1938 Boys' Life Article) - Airplanes and RocketsOnce upon a time there was an organization called the Boy Scouts of America, whose adult leadership sought to prepare generations of young men to be brave, enterprising, purposeful, resolute, enduring, partnering, assuring, reformed, enthusiastic, and devoted to himself, his community, and his country. Its membership was exclusively biological male. The fact that I used the term "biological male" is an indicator of what has gone tragically wrong with the BSA in the last decade or so with wokeness and infiltration by ne're-do-well agents of change. But, I digress. This aviation themed adventure article appeared in a 1938 issue of Boys' Life magazine, the official publication of the BSA. Its arctic locale...

Estes Astron Gyroc Model Rocket

Estes Astron Gyroc Model Rocket - Airplanes and RocketsThe Estes Astron Gyroc model rocket, introduced in the late 1960s, is a fascinating example of ingenuity in model rocketry. It was designed to demonstrate an innovative recovery method - spin recovery - that set it apart from traditional parachute or streamer recovery systems. The Gyroc became an instant hit among rocketeers due to its simplicity, affordability, and the spectacle of its recovery mechanism in action. A newer version called the "Tazz" is now being sold. It simplifies the building process. Development History The Gyroc was developed during a period when Estes Industries sought to expand the educational...

Message from Apollo 8, Christmas Eve, 1968

Earthrise Commemorative Stamp - Airplanes and RocketsWhile orbiting the Moon on Christmas Eve, 1968, NASA astronauts Frank Borman, Jim Lovell, and William Anders made a live broadcast from from the Apollo 8 command module, in which they showed video of the lunar surface and the Earth as seen from one of the spacecraft's portals. That flight produced the famous "Earthrise" photograph which is featured on a U.S. commemorative stamp issued in May of 1969 - just three months before Apollo 11 landed on the moon. On the ninth orbit, toward the end of the transmission, the three astronauts each took a turn reading from the book of Genesis, chapter 1, verses 1 through 10. They finished with, "And from the crew of Apollo 8, we close with good night, good luck, a Merry Christmas – and God bless all of you, all of you on the good Earth."

From Melanie and me here at AirplanesAndRockets.com, we wish you all a very Merry Christmas and a happy and prosperous New Year!

Honest John Rocket History

Honest John Rocket History, September 1968 American Aircraft Modeler - Airplanes and RocketsThe Honest John rocket, officially designated M31, represents one of the earliest tactical ballistic missile systems deployed by the United States Army. Its inception stemmed from the necessity for a reliable battlefield nuclear delivery system during the early years of the Cold War. Development began in 1950 under the auspices of the U.S. Army Ordnance Corps, with technical guidance provided by the Douglas Aircraft Company, which was contracted to bring the concept to fruition. By 1953, the Honest John was operational, making it the first surface-to-surface rocket in the U.S. arsenal designed to deliver nuclear warheads. Development Timeline and Key Personnel The Honest John program's roots trace back to increasing tensions in the post-World War II era, as the United States sought systems capable of delivering nuclear payloads without the need for long-range...

Model Builders at the 14th Aero Nationals

With the Model Builders at the 14th Nationals, October 1941 Flying Aces - Airplanes and RocketsLet's see... if this was the 14th Nationals contest, then that means the first one was held in 1941-14+1 = 1928. That date agrees somewhat with the Academy of Model Aeronautics' (AMA) website that documents the complete history of model airplane comteptition. To wit: "Airplane Model League of America (AMLA) Nationals, sponsored by American Boy magazine, set the standard for future events. Held in Detroit from 1928 to 1930, the two-day event featured the Mulvihill and Stout indoor and outdoor trophies, plus a scale static contest and an awards banquet." Another article sets 1923 as the first National Aeromodeling Championships, although the only event was Mulvihill. The AMA itself was officially founded in 1936. According to a June 1976 Model Aviation magazine article entitled, "What You Should Know About Balsa," balsa wood was not the most popular structural material for model airplanes until about the time of this contest. Pine and bamboo were often used before then.

Rubber Motor Testing

Rubber Motor Testing, August 1968 American Aircraft Modeler - Airplanes and RocketsAs with so many other aspects of technical application, the state of the art of rubber motors has advanced significantly since the writing of this article - not that the information contained herein is anywhere near obsolete (except trying to find Pirelli rubber). Rubber motor braiding techniques, lubricants, the rubber length, width, thickness, modulus, composition, has all been studied and characterized to the nth degree so most of the guesswork is gone as far as the actual motor performance is concerned. Still all the other variables in the airframe and propeller system (prop, bearing, gearing)...

Drones Shut down Wright-Peterson AFB

Drones Shut down Wright-Peterson AFB - RF Cafe"Unknown drone activity forced one of the U.S.'s most critical military installations to shut down for several hours late Friday evening and Saturday morning, officials confirmed. The incident prompted heightened security measures and temporarily halted operations at Wright-Patterson Air Force Base in Ohio. Home to the 88th Air Base Wing, Wright-Patterson is one of the largest and most strategically important bases in the U.S., tasked with advanced research, intelligence, and operations. Unauthorized drone activity in military airspace poses significant risks, from espionage to safety hazards. In audio recordings by the Air Force Base air traffic control, which were shared online, an operator can be heard saying they are diverting 'over base' air traffic..."

EMILY Remote Controlled Lifeguard

EMILY Remote Controlled Lifeguard - Airplanes and RocketsLifeguard duty is the latest application for radio-control systems and the combination of modern high-powered electric motors and Li-Ion batteries. An Arizona-based company called Hydronalix has created a robotic flotation device to deploy to reach swimmers in distress when a lifeguard can't get there soon enough. The robot is called EMILY, which is an acronym for Emergency Integrated Life-saving Lanyard. EMILY weighs 25 pounds, can go up to 25 miles per hour and can be used as a flotation device for up to six people. Its batteries will run the device for about 15-20 minutes...

The Man Who Flew with the Lion

Roscoe Turner - The Man Who Flew with the Lion, November 1961 American Modeler - Airplanes and RocketsThe 1939 Thompson Trophy Air Races, held in Cleveland, Ohio, was the final show for that series until after World War II. Roscoe Turner was there in his Meteor LTR-14 racer. He had won top spot the year before with a speed of 283 mph, and in 1939 at 282 mph. In a unique turn in aviation career tacks, Turner conjured up a scheme where, based on equally unique circumstances largely of his own design, adopted a lion as a mascot to sell his services as a corporate products promoter. His first big success was with Gilmore Oil, after which the lion was named. "Gilmore" flew around the country with Mr. Turner...

Cessna 336 | 337 Skymaster History

Cessna 336 | 337 Skymaster History - Airplanes and RocketsThe Cessna 336 and 337 Skymaster hold a unique place in aviation history as distinctive twin-engine aircraft with a push-pull configuration. Their design addressed the challenges of asymmetric thrust inherent in traditional twin-engine aircraft, with both engines mounted along the centerline - one in the nose as a tractor and the other in the tail as a pusher. Development began in the late 1950s, led by Cessna engineers under the leadership of company president Dwane Wallace. By February 1961, the first prototype of the Cessna 336 took to the skies, featuring a fixed landing gear design. Production of the 336 began in 1963, but it faced limitations in market success due to its performance constraints and non-retractable gear...

Bellanca 28-70 Irish Swoop Article & 4-View

Bellanca Irish Swoop Article & 4-View, August 1972 American Aircraft Modeler - Airplanes and RocketsDon Berliner wrote a historical article about the Bellanca 28-70 Irish Swoop racer for the August 1972 edition of American Aircraft Modeler magazine. Bjorn Karlstrom provided one of his masterpiece 4-view illustrations. I scanned, OCRed, and posted the contents for your convenience. The Academy of Model Aeronautics still provides full-size drawings and plans for most of the airplanes featured over the years. "The Bellanca 28-70 was a long-range air racer designed for James Fitzmaurice Irish pioneer aviator, who christened it Irish Swoop. Although it was built in time for the 1934 MacRobertson Race from England to Australia, it was never destined to be a competitive long-distance racer but it was ultimately reborn..."

Bird-Like Drones Walk, Hop, Jump into Air

Bird-Like Drones Walk, Hop, Jump into Air - Airplanes and Rockets"On the shores of Lake Geneva in Switzerland, École Polytechnique Fédérale de Lausanne is home to many roboticists. It's also home to many birds, which spend the majority of their time doing bird things. Flying is a lot of work, and many birds have figured out that they can instead just walk around on the ground, where all the food tends to be, and not tire themselves out by having to get airborne over and over again. 'Whenever I encountered crows on the EPFL campus, I would observe how they walked, hopped over or jumped on obstacles, and jumped for take-offs,' says Won Dong Shin, a doctoral student. 'What I consistently observed was that they always jumped to initiate flight, even in situations where they could have used only their wings.' Shin is author on a paper published today in Nature that explores both why birds jump to take off, and how that can be beneficially applied..."

Snapshots of the War

Snapshots of the War, March 1937 Flying Aces - Airplanes and RocketsUp until the United States of America officially entered what became known as World War II (on December 7, 1941, following the Japanese attack on Pearl Harbor), what we now call World War I was referred to only as "The War." Recall that is was dubbed by H.G. Wells to be "The War to End All Wars." It did not. This "Snapshots of the War" piece in the March 1937 issue of Flying Aces magazine features what air power looked like in the early days of World War II. Interestingly, the "cocarde" (aka "cockade") referred to in the wrecked De Havilland D.H.-4 was, according to most contemporary sources, a term used to describe similar insignia worn on military head dresses and jackets. Insignia painted on military equipment was called a "roundel." There is a very nice photo of a Clerget rotary engine as it was mounted in the Sopwith Camel, along with the twin Vickers machine guns mounted to fire through the propeller via synchronization ...

Flight Engineer

Howard Borden Flight Engineer Bob Newhart Show - Airplanes and RocketsThe role of the flight engineer is one of the most significant yet increasingly historical professions in the history of aviation. Introduced during an era when aircraft systems grew increasingly complex, the position of flight engineer bridged the gap between pilots and the intricate mechanical and electrical systems of larger, multi-engine aircraft. The history of the flight engineer position is closely tied to the evolution of aviation technology, airline operations, and the military's increasing reliance on heavy aircraft during and after World War II. The position of flight engineer first emerged in the 1930s with the advent of multi-engine commercial aircraft such as the Boeing 314 Clipper and the Douglas DC-4. These aircraft required a dedicated crew member who was responsible for monitoring and managing the various systems, including engines, fuel, hydraulics, pressurization, and electrical systems...

1st TV Airing of "A Charlie Brown Christmas"

"Peanuts on Television," by Charles Schulz - Airplanes and RocketsAs a lifelong admirer of Charles Schulz's Peanuts comic strip, I occasionally buy a collectible item like a Snoopy music box that plays "It's a Long Way to Tipperary," a plastic Schroeder and piano figurine, a Charlie Brown Skediddler, or a Snoopy astronaut from the Apollo era. This time I bought the edition of TV Guide that announced the first showing of the "A Charlie Brown Christmas" cartoon. Also in this edition is the announcement of plans to preempt regular programming to televise the launch of the Gemini VII spacecraft, which carried astronauts Frank Borman and James A. Lovell. It launched right on time at 7:30 pm on December 4th, 1965. "As his millions of fans long since have discovered, under that inept, ineffectual, bumbling exterior of Charlie Brown's there beats a heart as soft and sweet as a marshmallow. In the sequence on these pages, drawn exclusively for TV Guide by Charlie's creator, Charles Schulz, he becomes concerned about the true meaning of Christmas...

X-acto Knife Blade Usage Chart

X-acto Knife Blade Usage Chart - Airplanes and RocketsI've been using X-acto tools since my teenage years the early 1970s. Before that, my razor knife blades were either the single-edge hardware store type or double-edge blades copped from my father's safety razor (those were truly dangerous, even with one edge taped). Half a century later, I now have a selection of many flavors of X-actor blades and handles. As the chart above shows, there seems to be an X-acto blade for every purpose. I often wondered what they were all meant for, until I found this X-acto Blade Usage Chart from the company. Like most people, by far my most often used blade is the trusty #11. I've been through hundreds of them. X-acto also makes a wide variety of specially shaped carving blades, including vees, cups, circles (routers)...

Your Job in Aviation: Flight Engineer

Your Job in Aviation: Flight Engineer, October 1950 Air Trails - Airplanes and RocketsMost people these days are probably now aware of an aeronautical profession that up until around the early 1980s was a vital part of aviation - the flight engineer. This 1950s article in Air Trails magazine highlights what was at the time a very prestigious and sought-after position for people wanting professional level careers in both commercial and military aviation. Since the 1930s, aircraft were rapidly growing larger and more complex. Most had two to four engines, retracting landing gear, pressurized cabins, autopilots, electronic and celestial navigation, long distance routes, and increasingly crowded airways. All that plus en route and destination airport weather, and even ground traffic clutter at airports...

Symposium on Free Flight Adjustment

Symposium on Free Flight Adjustment, Part II (March 1957 American Modeler Magazine) - Airplanes and RocketsThis is part two of a series from the March 1957 issue of American Modeler magazine that briefly introduces a dozen winning free flight models and comments from their designers. Current day modelers who like to fly the vintage (old timer) airplanes might pick up a useful tip from the masters of the golden age of free flight. Materials have not changed a lot since then, other than maybe the use of carbon fiber in the airframe, and no doubt engine technology has gotten better, but the fundamentals of trimming for the powered and glide portions of free flight pretty much remain the same...

Jetco Superflite "Jet 50" Jetex-Powered FF Kit

Jetco Superflite "Jet 50" Jetex-Powered Free Flight ModelThis "Jet 50" kit was part of Jetco's Superflite series. It was designed to be powered by the venerable Jetex 50 rocket motor. It is one of the models I had as a kid in Mayo, Maryland, back in the late 1960s. It was a lot like building and flying the Estes Falcon rocket-powered glider. The big difference was that the "Jet 50" flew at a leisurely pace as the Jetex 50 motor burned for about 20-30 seconds with a gentle "hiss," whereas the Falcon blasted off with more of a "ssst" sound for about half a second whilst the craft ascended to a couple hundred feet high. Each had its advantages. The "Jet 50" could be trimmed to fly in a tight circle in the back yard of our half-acre lot, but the Falcon required bicycling over to Klinken's Field where there was a big open field of many acres.

Du-Bro Whirlybird 505 Helicopter Review

Du-Bro Whirlybird 505 Helicopter Review, March 1972 RC Modeler - Airplanes and RocketsThere is no doubt that Du−Bro set the stage for commercially produced radio controlled (R/C) helicopters with the Whirlybird 500. Its use of a top-mounted engine that relied on counter-torque to set the main rotor blades spinning was unique. There were a few published articles on homebrew free-flight helicopters that used the arrangement, and Cox even marketed a ready-to-fly model that had a Cox .020 engine mounted on top called the Sky Copter (I owned one as a kid in the late 1960s). To my knowledge all other R/C helicopter models used a gear or belt drive from the engine to the main rotor shaft. It is amazing that this quite top-heavy configuration flew at all. Du−Bro engineers deserve a lot of credit. Note extensive use of common Du−Bro products like wheel collars, pushrods and clevises, strip aileron hookups, brass tubing, and nuts, bolts and screws. A lot of assembly work was involved, including a good bit of soldering...

Hot Engines!

Hot Engines! (January/February1963 American Modeler) - Airplanes and RocketsRe-timing, cleaning up (air and fuel flow passages), freeing up (sliding friction), lightening and balancing (removing unnecessary material), and breaking in (initial running with rich fuel mixture while interfacing metal parts fit themselves to each other) are all part of the effort necessary to create winning engines for model racing events. This 1962 American Modeler magazine article predates Schnuerle porting (in model engines), ABC (aluminum, brass, chromium) cylinder liners, and modern metal alloys, but still the concepts are applicable to today's engines. It purpose is to instruct on proper engine break-in so that it will have a long lifespan. Wankel lovers will appreciate the homemade engine shown...

American Modeler Comics of Yore

American Modeler Comics of Yore, Comics from 1950s through Mid 1970s Vintage American Modeler Magazines (page 10) - Airplanes and RocketsThese couple vintage model aviation comics appeared in the May 1957 issue of the Academy of Model Aeronautics' American Modeler magazine. The one on page 8 might need some explanation in order "get it." Back in the era, aviation of all sorts - both model and full-size - was still a novelty for most people. When either type of aircraft was seen close to the ground where people could get up-close looks, a crowd would often gather. In this comic, a huge group of people stopped to watch the model airplane fly, so the modeler decided it was his civic duty to provide a show for the onlookers. Many decades ago, comic strips had a very broad appeal with people. Daily newspapers and magazines often carried a large variety of single pane comics and strip comics...

Quick Floats Article & Plans

Quick Floats Article & Plans - May 1973 American Aircraft Modeler - Airplanes and RocketsAirplanes and Rockets website visitor Rob P. wrote to ask that I post the construction article for George Wilson's "Quick Floats," which appeared in the May 1973 issue of American Aircraft Modeler magazine. It's nice to know that even with all the prefabricated floats available for purchase today that there is still someone who prefers to build his own. The original Quick Floats design was sized for a .60-powered stunt airplane, but you can easily scale them up or down as needed to fit your model. I normally do not include a full-resolution scan in order to give the AMA Plans Service an opportunity to sell a copy (very low prices); however, a visit to their website does not show a listing for Quick Floats. Click on the plans images below for the larger versions. Beware that scans from the magazine may contain skew ...

World's Largest Model Airplane Meet

World's Largest Model Meet, September 1949 Air Trails - Airplanes and RocketsFor what was probably one of the first major model aircraft contests following the end of World War II, the New York Daily Mirror's "Model Flying and Air Fair" drew a thousand contestants and a quarter of a million spectators to it Grumman Airport*, Long Island, venue. That gives you a good idea of how popular not just full-scale, but model airplanes were in the era. People were still fascinated with the concept of human flight, and the vast majority of people worldwide had never flown on an airplane of any sort. Note in the aerial view photo of the airport the huge number of cars - it's so obvious that it's easy to miss. Note Lew Andrews, who later went on to manufacture model airplanes under the name of AAMCo, was the Plymouth International Stunt Champion. One thing that occurred to me when examining the model photos is how the basic form of the control line speed model has not changed much over the decades...

Suzy Homemaker Items, 1967 Montgomery Ward Christmas Catalog

Suzy Homemaker Items, 1967 Montgomery Ward Christmas Catalog - Airplanes and RocketsLike many little girls who were born in the 1960s, Melanie had a small collection of Suzy Homemaker toy appliances. Old photographs from birthdays and Christmases past document the times they were received. Melanie had the Suzy Homemaker Oven / Stove and the Suzy Homemaker Clothes Iron. Since hers was long gone my the time we got married in 1983, we decided to look for them on eBay. As with just about everything ever made, we easily found them in nice condition. Neither the oven nor the iron came with their original boxes because those are very expensive. This page of Suzy Homemaker products appeared ...

OS Digital Digitron DS-3, 3-Channel Radio Control System

OS Digitron DP-3, 3-Channel Radio Control System - Airplanes and RocketsMy very first radio control system was an OS Digital Digitron DS−3, 3−channel system. I have wanted to get one for nostalgia's sake for a long time. I had a saved search on eBay for years and finally a few months ago, one came up for auction, which I won. My plan is to replace the original 27.195 MHz electronics with that of my 6−channel 72.750 MHz Futaba system, with necessary modifications to the gimbal potentiometers, NiCad battery, antenna mount, etc. I will need to add a dual rate switch somewhere inconspicuous so as to not detract from the original look. The results will be posted here when done ...

Model Making Offers Money Making Opportunities

Model Making Offers Money Making Opportunities (January 1957 American Modeler Magazine) - Airplanes and RocketsPrior to the advent of commonplace high-speed digital computers, designing advanced aircraft structures required a lot of effort building scale models and testing them in wind tunnels and, when possible, in actual flight. The process was both expensive and time-consuming. As computer simulations have been fine tuned, the need to build models have been nearly entirely eliminated. Modern aircraft can go from computer monitor to production with the full-size prototype being the first actual version of the plane to be built. This article from a 1957 issue of American Modeler magazine reports on some of the very labor-intensive experimental and scale models built for testing and concept verification. Many of the technicians who did the planning and building were hobbyists who were fortunate enough to gets jobs to get paid for engaging in their passion...

The Berliner-Joyce OJ-2

The Berliner-Joyce OJ-2, May 1968 American Aircraft Modeler - Airplanes and RocketsThe Berliner-Joyce OJ−2 was a multi-purpose biplane built for naval service. Its maiden flight was in 1931. As this American Aircraft Modeler magazine article photos show, it could be configured with wheels or floats. Berliner-Joyce Aircraft Corporation had is main offices in Baltimore, Maryland, which was a popular location for defense contractors then and now. The Glen L. Martin Company, manufacturer of the famous Martin B−10 Bomber, was also in Baltimore. The OJ-2 was in heavy competition with the Vought O2U Corsair, which, unlike its eventual and much more famous successor gull-wing, all-metal F4U Corsair, was a fabric-covered biplane. Someone at Vaught must have really been stuck on using the Corsair name ...

The Nearly Effortless Flight of the Albatross

The Nearly Effortless Flight of the Albatross - Airplanes and RocketsThe July 2013 edition of IEEE's Spectrum magazine had a really good article on a high tech study that is being done on the manner in which an albatross manages to fly great distances and for long periods of time while rarely needing to flap its wings. As shown in the thumbnail (and in the article), an albatross performs a series of rapid climbs into very strong wind, turns, and dives leeward nearly to the water's surface, then repeats the process over and over as it makes its way to its destination. The process is called dynamic soaring. R/C soaring pilots have been doing the same sort of thing for a few years now. Obviously the albatross figured out how to fly like that long before mankind was able to mimic it, but the researchers in the article seem to not have knowledge of the R/C soaring technique. They are capturing albatrosses in their nests and attaching GPS-based sensors with data recorders to the birds' back feathers and retrieving the units when the birds return to their nests...

Cox Sky Copter Free Flight Helicopter

Cox Sky Copter Free Flight Helicopter - Airplanes and RocketsIn the late 1960s when I received a Cox Sky Copter free flight helicopter for Christmas, there was very little in the way of commercially available flying model helicopters. It was modeled after the Bell 47−G, which was later made famous by the M.A.S.H. television series. Victor Stanzel sold its tethered ElectroMic "Copter" that was powered by a pair of "D" cell batteries. As far as I know, Cox made the only nitro fuel powered free flight helicopter, named "Sky Copter." It was powered by a Cox .020 engine mounted to the top-center of the main rotor shaft, and caused the rotors to turn due to the counter torque cause by the propeller on the .020. It worked very well. After getting the engine started, you would give the rotors a spin in the clockwise direction (looking down from the top), and the gently push the model straight up. My guess is that most of the lift was provided by the engine's propeller pushing air down, and that the spinning rotors served primarily to stabilize the model during powered flight. Once the engine quit, the spinning rotors essentially went into a counter-rotation mode to gently bring the Sky Copter back to terra firma...

Du-Bro Tri-Star Review, December 1975 RC Modeler

Du-Bro Tri-Star Review, December 1975 RC Modeler - Airplanes and RocketsDu-Bro was the first American company to produce a radio control helicopter kit - the Whirlybird 505. That was sometime around 1972 It was modeled after the way free flight helicopters were built an the engine and propeller sitting on top of the main rotor, using a free-wheeling rotor that turned in response to the counter torque of the engine. Fixed pitch rotor blades were controlled via a flybar assembly as was the case prior to the advent of flybarless rotor heads. Du-Bro's next helicopter was a much-improved and very popular Hughes 300, using a driven rotor with the engine mounted in the fuselage. It also used a flybar for rotor control. Building off that success, they next introduced this TriStar R/C helicopter. It was smaller than the Hughes 300 and modeled after the RotorWay Scorpion homebuilt ...

Model Boat Record Breakers

When most people think about control line (CL) models, airplanes are what comes to mind. However, prior to the advent of miniature, reliable radio control (RC) systems, model boats and model cars also ran on control lines, as reported in a 1957 issue of American Modeler magazine. Most of the time they went in circles, just like model airplanes do; however, some hobbyists stretched out long sections of straight line in order to get maximum speeds from their craft. Unlike with model airplanes where an operator in the center of the circle exerted control of the elevator (and sometimes throttle), the control line boats and cars generally ran with no form of control. In fact, usually the models were tethered with a single line in the center of the circle and the operator handled the boat or car from the outside...

"Flyin' Jenny" Comic Strip: January 2, 1944

"Flyin' Jenny" Comic Strip: January 2, 1944 Baltimore Morning Sun - Airplanes and RocketsThis is the Sunday, January 2, 1944, "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 ...

WWI Ace von Schleich & His Roland C-II Wahlfisch

World War-1 Ace von Schleich and his Roland C-II "Wahlfisch" Plans for U/Control C-II, September 1962 American Modeler - Airplanes and RocketsDouglas Rolfe's sketch of this Roland C-II biplane is another example of his amazing ability not just to create a drawing, but to depict the model's construction features in a manner helpful to builders. That, coupled with the masterfully detailed and laid-out plans by Walter Musciano and a brief history on the airplane along with its most famous pilot, Eduard von Schleich, makes this an article you won't want to miss - especially if you are a World War I historian. I have to wonder whether Eduard von Schleich's fellow Flieger (aviators) referred to him as "verrückte Augen" ("crazy eyes")?...

How to Recondition Vise Grip Pliers

How to Recondition Vise-Grip Pliers - Airplanes and RocketsMy Vise-Grip pliers have performed a lot of hard duty over the decades. Many rusted nuts and bolts would still be unremoved if it weren't for their sharp, corrugated locking jaws. I have 10", 7", and 4" w/cutter, and 6" long nose models. These are all manufactured under the Petersen Manufacturing Company name, before they bought Irwin, who now manufactures Vise-Grips. Even high quality tools eventually show signs of wear after decades of use and abuse. A few of mine had jaws worn down to the point where they no longer would "bite" into the bolt head or nut being clamped. I was about to buy a couple new pairs of Vise-Grips, but then wondered if I could recondition the jaws to put the pointed shape back on the jaws with a triangle file ...

Boeing B&W 1916 Biplane

Boeing B&W 1916 Biplane March 1965 Model Airplane News - Airplanes and RocketsHere are plans for the Boeing B&W 1916 Biplane that I electronically scanned from my purchased copy of the March 1965 Model Airplane News magazine. When I have more time, I will dig the magazine out of storage and scan/OCR the rest of the article. For now you can at least review the plans. Click on the images for larger versions. I have even large files for them at the original 200 dpi resolution. Designed and built by Mr. Francis Reynolds. Plans for this fine model were drawn by Mr. Ray Vinup. All copyrights (if any) are hereby acknowledged. "The Boeing Model 1, also known as the B & W Seaplane, was a United States single-engine biplane seaplane aircraft. It was the first Boeing product and carried the initials..."

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)...

Jean Shepherd's Model Airplane Radio Broadcast

Jean Shepherd's Model Airplane Radio Broadcast - Airplanes and Rockets

Jean "Shep" Shepherd, most recently known for the movie "A Christmas Story," spawned by his book entitled "In God We Trust: All Others Pay Cash," was widely known in the 1950s through 70s for his ad hoc story telling on AM radio stations like WOR in NY City. Shep was an avid amateur radio enthusiast his entire life, and told anecdotes about it often while on the air. He was also an airplane modeler in his younger days. This May 3, 1973 Model Airplanes broadcast by Shep recounts the time he and his friend Schwartz (a real guy and one of The Christmas Story" characters), as teenagers, pooled their paper route money to buy and build Flying Quaker R/C airplane from plans, with a Brown engine and home-built radio gear (they were both Hams with electronics skills). It was nearly a year-long project for them. On the Flying Quaker's maiden flight, it got caught up in a strong thermal. Listen to his story to learn how it turned out ...

QuinStar Technology Engineer Captures Orion Nebula

QuinStar Technology Engineer Captures Orion Nebula - RF CafeAt QuinStar, we're about more than millimeter-wave technology. The people comprising QuinStar Technology pursue diverse and exciting outside interests. Our Chief Engineer, Jim Schellenberg, is a highly skilled amateur astronomical photographer. He captured this beautiful image of the Orion nebula using a specially modified Canon 6D. The camera responds to the H-alpha spectral line at 656 nm (from hydrogen gas), which is seen as red in the photo. The camera is mounted on an 11-inch telescope that tracks the object as the earth rotates. This image consists of nine one-minute exposures that are "stacked" to form the image you see. This is an excellent time of the year to view the Orion nebula. It can be seen with the naked eye ...
