PEP Engine Ad, June 1960 Aero Modeller

PEP Engine Ad, June 1960 Aero Modeller - Airplanes and RocketsPrior to the advent of the Internet, receiving information on foreign modeling activity was pretty much limited to what the U.S. publications like American Modeler and Model Airplane News decided to print. Even that was limited to things like flying events and not to specific products. Before a few years ago, I had never heard of PEP engines, a product of Electronic Development, Ltd., of Surrey, England. This full-page advertisement from a 1960 issue of Aero Modeller magazine promotes PEP's line of diesel engines. Along with the English spelling of words like "aluminium," it mentions a type of metal called "Mehanite" and another called "Hiduminium." Another advantage of the Internet is the ability to look up unfamiliar terms like that which would never be found in the Webster's Dictionary on my bookshelf. Mehanite ...

How Flying Cars Could Change the Aerospace Industry

How Flying Cars Could Change the Aerospace Industry - Airplanes and Rockets"A new study of the environmental sustainability impacts of flying cars (electric vertical takeoff and landing aircraft, or VTOLs) finds that they wouldn’t be suitable for a short commute but could be valuable in congested cities or in places where there are geographical constraints. The found that for trips of 62 miles, a fully loaded VTOL carrying a pilot and three passengers had lower greenhouse gas emissions than ground-based cars with an average vehicle occupancy of 1.54. Emissions were 52% lower than gasoline vehicles and 6 percent lower than battery-electric vehicles ..."

Fighter Jets with Missile-Killing Lasers

Fighter Jets with Missile-Killing Lasers - Airplanes and Rockets"U.S. Air Force says a ground-based laser downed multiple test missiles over New Mexico. A successful ground test has moved the U.S. military one big step closer to putting anti-missile lasers on its aircraft. A ground-based laser shot down 'several' missiles in flight during an April 23 test at the White Sands Missile Range in New Mexico, Air Force officials said. Run by the Air Force Research Laboratory, or AFRL, the test was part of the Self-Protect High Energy Laser Demonstrator, or SHiELD, a program intended to protect aircraft from incoming missiles. AFRL officials said security reasons prevented them from saying how many missiles were downed in the test. The laser that the Air Force lab used for the test was ground-based ..."

Berkeley Models Privateer

Berkeley Models Privateer (Steven Krick) - Airplanes and RocketsMr. Steven Krick wrote to ask a question about my method for applying Silkspan on an open frame area on a vintage Berkeley Privateer seaplane model he is in the process of building. After imparting some of my limited knowledge on such matters, he responded with some photos of the framed-up Privateer. A few days he followed with a photo after the Silkspan has been applied. Hopefully, more images will be made available as the progress continues. A Cox .049 is being used for power. The Privateer was - and still is- a very popular amphibious model. When Berkeley first produced the kit, modelers built it for radio control, control line, and free flight ...

Drones Swarms Piloted by AI to Patrol Europe's Borders

Drones Swarms Piloted by AI to Patrol Europe's Borders - Airplanes and Rockets"Imagine you’re hiking through the woods near a border. Suddenly, you hear a mechanical buzzing, like a gigantic bee. Two quadcopters have spotted you and swoop in for a closer look. Antennae on both drones and on a nearby autonomous ground vehicle pick up the radio frequencies coming from the cell phone in your pocket. They send the signals to a central server, which triangulates your exact location and feeds it back to the drones. The robots close in. Cameras and other sensors on the machines recognize you as human and try to ascertain your intentions. Are you a threat? Are you illegally crossing a border? Do you have a gun? Are you engaging in acts of terrorism or organized crime? The machines send video feeds ..."

3D Rocket Factory Takes Flight

3D Rocket Factory Takes Flight - Airplanes and Rockets"A rocket manufacturer pioneering 3D printing technology is scheduled to loft its first payload into orbit as early as 2021 under terms of a deal between the aerospace startup and a launch services provider. Relativity Space said this week it has signed a launch services agreement with Spaceflight, a satellite rideshare and mission management specialist. The deal calls for Spaceflight to book satellite launches to low-earth orbit using Relativity's Terran 1 rocket, an entirely 3D-printed rocket. Relativity bills itself as the aerospace industry's first autonomous rocket factory and launch service integrating machine learning and intelligent robotics with 3D autonomous manufacturing technology. The startup claims it can build a rocket using additive manufacturing ..."

Vintage Northrop Flying Wing Crashes

Vintage Northrop Flying Wing Crashes - Airplanes and Rockets"A restored one-of-a-kind 1944 flying-wing airplane owned by the Planes of Fame Air Museum crashed April 22 during a flight to prepare for an upcoming airshow, killing the pilot. The crash of the Northrop N-9MB on the grounds of a state prison near the Chino Airport, where the museum is located, occurred under unknown circumstances. News accounts reported that the pilot had stopped responding to calls from the Chino Airport control tower about seven minutes after takeoff from the airport. There were no serious injuries of persons on the ground reported at the California Rehabilitation Center in Norco ..."

Dornier Do-335 A-6 Scale Model by Steven Krick

Dornier Do 335A-6 Scale Model (Steven Krick) - Airplanes and RocketsOne of the advantages of publishing a website like AirplanesAndRockets is that occasionally I get contacted by modelers of exceptional skill and, in sometimes, renown within the modeling universe. Such was the case recently when Mr. Steven Krick (a USAF jet engine mechanic many moons ago) wrote to ask a question about my method for applying Silkspan on an open frame area on a vintage Berkeley Privateer seaplane model. After receiving my response, he mentioned his other model airplane building aspect - that of highly detailed plastic scale kits like this Dornier Do−335 A−6, a World War II era twin engine craft in a pusher-tractor configuration. According to the Wikipedia entry on the Do−335, the "A−6" version was a "two-seat night fighter aircraft, with completely separate second cockpit located above and behind the original." A few years back at the Erie International Airport ...

Model Aviation Comics, January 1961 American Modeler

Model Aviation Comics, January 1961 American Modeler Magazine - Airplanes and RocketsThese couple model aviation-related comics appeared in the January 1961 American Modeler magazine. I'm not quite sure what message the first one is attempting to convey, with the guy peering through a seafarer's spyglass to see his model airplane at the end of the control lines. Maybe it is meant to imply the lines being used are really long, or that his model it really tiny. Note the telescope dome in the background. Enjoy!

D-Day, June 6, 1944 - 75th Anniversary

D-Day, June 6, 1944 - RF CafeTime heals all wounds, as the saying goes. Since the days of gruesome wars, both victor and loser countries have managed to establish civil relations and forgiveness for past actions. Some have thrived, as between the U.S. and Japan and Germany, while others have not. Ultimately, it is the greed for money, quest for power, and/or religious zeal of a relative few at the top of national offices who cause the problems while their people pay the price. So, too, do people of countries that choose to oppose tyranny and free the world's oppressed. Time also erases memories of those actions of men and women that caused the wars and attendant suffering and loss. Today, very few people can tell you anything about D-Day. Socialism and its many forms are gaining popularity again based on ignorance. Nazism = National Socialism. Beware. Listen to President Franklin D. Roosevelt's D-Day prayer from June 6, 1944.

How to Make a Propeller in Six Days

How to Make a Propeller in Six Days - Airplanes and RocketsThis is pretty amazing. "Culver Props specializes in making custom, fixed-pitch, two-blade, wood propellers. Lewis makes about 120 propellers a year. The path: Lewis was taught by her grandfather, a mechanical engineer. 'I worked here while I was going to college,' says Lewis, 'doing the things nobody else wanted to do, like answering the phones. My grandpa taught me everything as we went along, and I've been doing this now for 10 years. He passed away in 2016, so I continued the business - me and my 84-year-old granny, who comes in every day and helps me. We specialize in the larger-diameter propellers, a lot of World War I replicas. That's our sweet spot ..."

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 ...

Chinese Hypersonic Vehicle Model for Future Weapon System

Chinese Hypersonic Vehicle Could Be Model for a Future Weapon System - Airplanes and Rockets"The hypersonic vehicle appears similar to an American hypersonic weapon development project, HAWC. Images on Chinese social media appear to show a hypersonic test vehicle that is a likely prototype for a weapon system. The Jia Geng No. 1 rocket, allegedly built for hypersonic research, appears very similar to an American concept for a hypersonic cruise missile. The images, which recently surfaced in Chinese language media, show the Jia Geng No. 1 rocket, a collaboration between Xiamen University Aerospace Academy and Beijing Lingkong Tianxing Technology Co., Ltd. The images show a rocket 28.5 feet long by 2.5 8.2 feet wide ..."

Keck Telescopes Get a Motion Control Upgrade

Keck Telescopes Get a Motion Control Upgrade - Airplanes and Rockets"In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea mountain summit has no nearby ranges to roil the upper atmosphere, and for most of the year, this atmosphere is clear, calm, and dry, enabling the W. M. Keck Observatory, with its twin 10-meter-mirror telescopes, to observe our galaxy and beyond at levels special to it since opening in the early 1990s. Now, after the completion of a significant nine-year motion control upgrade project, the Keck Observatory telescopes, each standing 30 meters (almost 100 feet) tall, are offering data and observations with new and impressive nanometer precision. And all changes were made without experiencing any downtime on either telescope ..."

NASA Unveils Radically New Airplane Wing

NASA Unveils Radically New Airplane Wing - Airplanes and Rockets"Most planes use rigid wings with moving parts. But what if there was a wing that was not only completely flexible, but could be programmed to change on the go? A wing that could adapt to the most efficient shape for any flight, wind conditions or scientific mission? MADCAT is making that wing a reality. The Mission Adaptive Digital Composite Aerostructure Technologies, or MADCAT, team at NASA's Ames Research Center in California’s Silicon Valley, uses carbon fiber composites - a strong and light material made of carbon atoms - to design and test efficient, ultra-light wings that can adapt on the fly ..."

Cunningham on R/C: Edsel Murphy's Law

Cunningham on R/C: Edsel Murphy's Law, March 1972 R/C Modeler - Airplanes and RocketsOne of the monthly columns in R/C Modeler magazine, written by Chuck Cunningham, entitled "Cunningham on R/C," that reported on the current state of radio control, which had only fairly recently evolved into fully solid state, proportional control systems. Anyone involved in electronics is painfully familiar with the weird kinds of issues that crop up in complex circuits that operate in hostile environments. The March 1970 issue contained part of an article authored by D. L. Klipstein, Director of Engineering, Measurement Control Devices, entitled, "Murphy's Law: The Contributions of Edsel Murphy to the Understanding of the Behaviour of Inanimate Objects.*" Only a few of the items were printed in Cunningham's column, but I managed to locate a copy of the full article ...

Alain Pons' Turbojet "Duck" Canard

Alain Pons' Turbojet "Duck" Canard - Airplanes and RocketsThe turbojet-power version of "Alain's Duck" canard has made its maiden flight. As you can see in the video (on the page), it handles as smoothly as the other versions. Of course Alain's piloting skills play at least a small part in how well she flies. More details will follow once Alain supplies them ...

McCall's Pattern #8346 Miniature House, Furniture and Families

McCall's Pattern #8346 Miniature House, Furniture and Families - Airplanes and RocketsSometime back in the 1990s when our daughter, Sally, was around three years old, her grandmother (Melanie's mother) made one of these Rabbit Family House sets from the McCall's pattern #8346. Grandma was a very craftsy person who had decades of experience making rugs, wall hangings, quilts, clothes, and decorative items. You can see from the pattern instructions that a lot of work is involved with many different types of skills required. Now that we have a five-year-old granddaughter, Melanie decided it would be nice to make a Bunny House for her. Sally found the pattern package at a Goodwill store, and it was of the same vintage as the one Melanie's mother used. At first, the plan was to make one that looked like Sally's ...

AMA Notice: Exception for Limited Recreational Operations of Unmanned Aircraft

AMA Notice: Exception for Limited Recreational Operations of Unmanned Aircraft - Airplanes and RocketsEarlier today, the FAA issued a notice that provides temporary guidance for recreational fliers. AMA is already working with the FAA to make accommodations for our members, and we wanted to let you know what to expect. First, we’ll share a bit of background. Throughout the past few years, thousands of new recreational drone users and more than 400,000 new commercial drone operators have entered the airspace. Late last year, Congress passed and President Donald Trump signed into law the FAA Reauthorization Act of 2018. This law gives the FAA more authority to address the surge of new users and changing airspace. Part of the law includes Section 349, which outlines eight statutory requirements for the recreational operation of all unmanned aircraft, including all drone and model aircraft hobbyists ...

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 ...

Drone Delivery Service Launched in Australia

Drone Delivery Service Launched in Australia - Airplanes and Rockets"Alphabet's subsidiary Wing announced this week that it has officially launched a commercial drone delivery service 'to a limited set of eligible homes in the suburbs of Crace, Palmerston and Franklin,' which are just north of Canberra, in Australia. Wing's drones are able to drop a variety of small products, including coffee, food, and pharmacy items, shuttling them from local stores to customers’ backyards within minutes. We've been skeptical about whether this kind of drone delivery makes sense for a long, long time, and while this is certainly a major milestone for Wing, I'm still not totally convinced that the use-cases that Wing ..."

Ace R/C Mini Foam Wing Resources - Constant & Tapered Chord

Ace R/C Mini Foam Wing Resources - Constant & Tapered Chord - Airplanes and RocketsUp until sometime in the early 2000s, Ace R/C manufactured a very popular set of injection molded foam wings for ½A size models - the Ace R/C Mini Foam Wing. There was a constant chord and a tapered chord version. Up until fairly recently, a third-party firm was selling equivalent foam wing panels eBay. Of course you can often buy original Ace R/C Mini Foam Wings on eBay so you might want to check periodically to see if they appear. Laser Design Service and Balsa Builder both offer a balsa built-up version of the foam wing. Andy Kunz has a free plan for cutting and building your own Ace tapered chord mini foam wing replica. Owen Kampen and others designed and kitted many ½A airplanes using his Mini Foam Wing cores ...

Mach 25 'Spaceplane' Passes Crucial Test

Mach 25 'Spaceplane' Passes Crucial Test - Airplanes and Rockets"A 'spaceplane' that flies 25 times faster than the speed of sound has successfully passed a crucial testing milestone. The hypersonic plane is so fast it could jet from London to New York in less than 60 minutes and transport you from the UK to Australia in four hours. Oxford-based Reaction Engines has been working with the European Space Agency and the UK Space Agency, along with BAE Systems, to make the powerful aircraft. Reaction Engines has recently been testing a 'pre-cooler' for the plane, which is technology that would allow it to travel faster than ever before. The pre-cooler is critical in the plane's development because it is required to stop the engine from melting by lowering the temperature of compressed air in the engine ..."

Hobby Lobby International Advertisement

Hobby Lobby Advertisement, July 1978 R/C Modeler - Airplanes and RocketsFounded in 1964 and located in Brentwood, Tennessee, Hobby Lobby International closed its doors a couple years ago. Born in an era when many - if not most - products used by aircraft, boat, and car modelers were manufactured here in the United States, Hobby Lobby served the entire spectrum of modeling. Hobby Lobby did offer many hard-to-get foreign kits as well, though. It was the first mail-order hobby shops that I remember using. There were not any "real" hobby shops near my Mayo, Maryland, home as a kid, so unless I could whine enough to get my father to drive me the 20+ miles to the nearest hobby shop, the only alternative was to cut out the order form, fill it out, have my mother write a check (from money I earned on my paper route), stuff it all in an envelope ...

Growing Drone Industry Spawns a Growing Antidrone Industry

Growing Drone Industry Spawns Growing Antidrone Industry - Airplanes and Rockets"Drone sightings at London's Gatwick Airport disrupted operations there for three days last December, and in January, rumored sightings near Newark [N.J.] Liberty International Airport delayed incoming air traffic temporarily. These incidents highlighted a growing problem with small drones: Miscreants, or just clueless operators, can make real trouble by flying these machines where they're not allowed. Rogue drones have been a long-standing worry for regulators, who have pursued a wide array of ideas to address the issue. Now, the U.S. Federal Aviation Administration is preparing a new report on the matter ..."

Airtronics Aquila Product Review in the December 1975 R/C Modeler

Airtronics Aquila Product Review, December 1975 R/C Modeler - Airplanes and RocketsIt was in the May 1975 issue of R/C Modeler magazine that I first saw the Airtronics Aquila sailplane (she's way too graceful to refer to her merely as a glider). Airtronics had not introduced a kit yet, but they were selling a canopy and hardware kit along with plans, so I ordered them and scratch built my first Aquila. I was 17 years old then. It was covered to look like the one in the photo above (which would become the kit box label photo). Not having lite ply for the fuselage, I used hard balsa. Somehow I eventually managed to destroy Aquila #1, but by that time a kit was available, so I bought one and also the ABS plastic fuselage. A standard Hi-Start was used for launching. Back in the 1970s, there were still plenty of areas, even near small cities, to stretch out a Hi-Start ...

Foldable Drone Flies through Narrow Holes

Foldable Drone Flies through Narrow Holes - Airplanes and Rockets"Inspired by birds that fold their wings in the air when space is limited, researchers from the University of Zurich and EPFL have developed a new foldable drone. The researchers designed the quadrocopter with four independently rotating propellers. The propellers are mounted on mobile arms that can be pivoted around the main frame with the help of servomotors. The control system regulates, in real time, each new position of the arms and adjusts the propeller speed depending on the center of gravity. The drone's default configuration is X-shaped, but it can adapt into H, O, and T shapes ..."
