UK Set to Launch from British Soil

UK Set to Launch from British Soil - Airplanes and Rockets"Another step towards space exploration from UK soil has been unlocked, with the passing of the spaceflight regulations, Transport Secretary Grant Shapps announced 29 July 2021. The legislation provides the framework to regulate the UK space industry and enable launches to take place from British soil for the very first time. It will unlock a potential 4 billion pounds of market opportunities over the next decade, creating thousands of jobs and benefiting communities right across the UK. This also puts the UK in a unique position as the first country in Europe able to launch spacecraft and satellites from home soil..."

AIRMEET 2021 Happening Live Today

Air Meet 2021 Horizon Hobby - Airplanes and RocketsAIRMEET 2021 is happening today, Saturday, August 14th, 2021. The Horizon AIRMEET has stood for top-class RC action for 13 years now. The non-stop air show with the best pilots on the scene has developed over the past decade into an RC festival that is unique worldwide. The combination of spectacular RC displays with breathtaking full-size acts makes the hearts of all flight enthusiasts beat faster every year. Once a year, Horizon Hobby turns the airfield in Donauwörth, Bavaria, into the absolute RC hotspot.

Douglas A-20 Boston / Havoc Bomber Article & Drawings

Douglas A-20 Boston / Havoc Bomber Article & Drawings, November 1970 AmericaHere are detailed drawings for the Douglas A-20 Boston / Havoc Bomber that I electronically scanned from my purchased copy of the November 1970 American Aircraft Modeler magazine. Per Wikipedia: "The Douglas A-20 Havoc (company designation DB-7) is an American medium bomber, attack aircraft, night intruder, night fighter, and reconnaissance aircraft of World War II. Designed to meet an Army Air Corps requirement for a bomber, it was ordered by France for their air force before the USAAC decided it would also meet their requirements." Because the drawings span two pages, you will need to adjust the size and alignment a bit to get halves to line up properly. From there, with some extra effort you should be able to create plans for a model if plans can no longer be purchased or you just enjoy drawing plans (I do). Line drawings for this fine model were created by Mr. Björn Karlström...

Aircraft Marking of All Nations

Aircraft Marking of All Nations, November 1934 Flying Aces - Airplanes and RocketsI was surprised to find in this 1934 issue of Flying Aces magazine that the European countries of Finland and Latvia used Swastika insignia. The Germans were not the only country that used a Swastika for military markings. According to Wikipedia, many Asian nations and religions used the swastika (pointing clockwise) or the sauwastika (pointing left) long before the National Socialist German Workers' Party (Nazi Party) decided to adopt it as their organizational symbol. It would have been nice if Flying Aces had supplied the chart of early 20th Century aircraft country insignia in color, but back in the day color on anything other than the cover was very rare. Fortunately, they labeled many areas with what their color should be. I was going to colorize the symbols, but without knowing the true shades, doing so might do more harm than good if someone were to search for a color scheme...

Stratospheric Balloons for Monitoring and Surveillance

Stratospheric Balloons for Monitoring and Surveillance - Airplanes and Rockets"These eyes in the sky fly above drones and below satellites. Alphabet's enthusiasm for balloons deflated earlier this year, when it announced that its high-altitude Internet company, Loon, could not become commercially viable. But while the stratosphere might not be a great place to put a cellphone tower, it could be the sweet spot for cameras, argue a host of high-tech startups. The market for Earth-observation services from satellites is expected to top US $4B by 2025, as orbiting cameras, radars, and other devices monitor crops, assess infrastructure, and detect greenhouse gas emissions. Low altitude observations from drones could be worth. Balloons in the stratosphere, 20 kilometers above Earth (and 10 km above most jets), split the difference..."

Swedish Saab J 21 Fighter

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

Window Flower Boxes on Shelves

Window Flower Boxes on Shelves - Airplanes and RocketsDuring our frequent walks around the neighborhood here in Erie, Pennsylvania, Melanie and I would see houses that had flower boxes installed beneath the windows and vowed that some days we would do the same for our house. Finally, as a present to Melanie for her birthday, I made measurements and drew up some plans for a set to put on the front of our house. After doing a search on the Internet for ideas, I decided on a fairly unique configuration where the boxes themselves sit on a shelf that is mounted to the house. That allows the boxes to be easily removed for servicing, and per one website, to be replaced in the fall and winter with an arrangement of gourds, small evergreens, and various other seasonal decorations...

Across the Channel in a Nazi Helicopter

Across the Channel in a Nazi Helicopter - Airplnes and Rockets"Hans-Helmut Gerstenhauer earned a place in history. He would have settled for a job. A cold wind cuts across the boggy heathland of the New Forest on the southern coast of England. Wild ponies drink from the puddles that the heavy rain has left behind. At first there appears to be nothing left of RAF Beaulieu and the Airborne Forces Experimental Establishment (AFEE) that covered the heath in concrete. The British Parachute Regiment was established in 1942, and the AFEE was the unit tasked with researching and testing parachutes and the aircraft that would carry the jumpers - gliders, and beginning in 1945, helicopters. From the air, the ghostly A-shape outline of the crisscrossing runways can still be seen, but on the ground, traces are hard to find..."

Comet Sabre 44 Ready-to-Fly C/L Model

Comet Sabre 44 Ready-to-Fly C/L Model, January 1955 Model Airplane News - Airplanes and RocketsThis full-page advertisement for Comet's Sabre 44 control line "gas" model appeared in the January 1955 issue of Model Airplane News. Ready-to-fly "gas" models were just entering the market at the time. The "All Plastic" model preceded Cox's popular line of ready-to-fly plastic control line models. Whereas the Cox models used their own line of .049 and .020 glow fuel engines, Comet used the 1/2A-Herkimer 049B engine. The $9.95 price tag in 1995 is the equivalent of $101.25 today, which is really about what such a model with engine would cost now if anyone made such a product (which they don't)...

Scale-Like Curtiss P-40 Stunter

Scale-Like Curtiss P-40 Stunter Article & Plans, March/April 1963 American Modeler - Airplanes and RocketsHere are the plans and article for Charles Parrott's semi-scale Curtiss P-40 Warhawk control line stunt model as they appeared in a 1963 issue of American Modeler magazine. It sports a 38" wingspan and is powered by an inverted-mounted Fox .35 Stunt engine fed by a modified Veco 3.5 ounce fuel tank. There was an effort in the era to have competition stunt models resemble real-life airplanes, even though exaggeration of fuselage, wing, and tail surfaces were required to facilitate stunting. As is evidenced by today's top control line stunt models, the fad gave way to structures designed specifically for accommodating the needs of flight. Even full-size aircraft design moves in that direction over time, where traditional features and methods give way to modern technology and materials. Compare the look of a production composite frame general aviation airplane from Diamond Aircraft or Cirrus Aircraft...

Ghostships of the Air

Ghostships of the Air - Airplanes and Rockets"A photographer takes us on a spooky tour of abandoned aircraft. We can't help being tantalized by the sight of derelict airplanes. Their mere presence represents a mystery, a backstory of abandonment we yearn to hear. Award-winning Russian photographer Dmitry Osadchy knows that well, and uses his drone cameras to take us on a world tour of aviation's ghostships. Some of the airplanes rest alone in barren landscapes, like the F104 Starfighter pictured above, on an abandoned airfield near Crete. Others are clustered together in mass graves. Either way, they all possess a strange, forlorn beauty. Here's a selection of Osadchy's imagery..."

"The Langley" Mulvihill Winner  

 "The Langley" Mulvihill Winner, July 1962 American Modeler - Airplanes and RocketsAirplanes and Rockets website visitor Peter W. wrote to ask that I scan and post this "'The Langely' Mulvihill Winner" article that appeared in the July 1962 issue of American Modeler magazine. Designer and flyer Frank Parmenter wrote the article. Per the Academy of Model Aeronautics website on the history of the Mulvihill free flight competitions: "Major Bernard Mulvihill, born June 8, 1890, in Pittsburgh, Pennsylvania, was a full-scale and model aviation enthusiast at the beginning of the era of flight. In the model aviation world, Mulvihill was a member of the Aero Club of America and served as president of the local Aero Club of Pittsburgh. He helped the Pittsburgh club negotiate permission to fly at the nearby Government Aerial Field. Mulvihill saw the value in encouraging youth to build models...

Nothing Can Keep This Drone Down

Nothing Can Keep This Drone Down - Airplanes and Rockets ""It uses elytra, a beetle-inspired set of wings, to self-right itself. When life knocks you down, you’ve got to get back up. Ladybugs take this advice seriously in the most literal sense. If caught on their backs, the insects are able to use their tough exterior wings, called elytra (of late made famous in the game Minecraft), to self-right themselves in just a fraction of a second. Inspired by this approach, researchers have created self-righting drones with artificial elytra. Simulations and experiments show that the artificial elytra can not only help salvage fixed-wing drones from compromising positions, but also improve the aerodynamics of the vehicles during flight. The results are described..."

Pietenpol Air Camper

Pietenpol Air Camper, March 1961 American Modeler Magazine - Airplanes and RocketsWhile not specifically drawn as plans for building a model of the Pietenpol Air Camper, all the detail and dimensions necessary for scaling to any size is possible using these sketches which appeared in the March 1961 issue of American Modeler magazine. The "Piet" has been as popular a subject for modeling as is was and still is for building full-size aircraft. Originally designed in 1930 by Bernard Pietenpol, the craft borrowed many of its metal parts from Ford automobiles, including the engine and suspension spring for a tail skid. Aircraft Spruce & Specialty Company still sells Sitka spruce wood kits for the full-size Pietenpol Air Camper; the total as of this writing is less than $4,000. You can be sure the information contained in this article is trustworthy because it was authored by Mr. Pietenpol himself!

Ray Models "Ray-Jets"

Ray Models Advertisement, November 1946 Air Trails - Airplanes and RocketsThis Ray-Jets advertisement appeared in the November 1946 issue of Air Trails magazine. The name is unfamiliar to me. The company claims to have the first jet-propelled models, which use their brand of "Rocket Units" that use "no fire," "no chemicals," and are "absolutely harmless." It was obviously not some form of the Jetex rocket engine since they did not enter the marketplace until 1958. According to the Model-Plans.co.uk.com website, which has good info on the Ray Models kits, the "Rocket Unit" was a CO2 cartridge that get punctured at launch. The Jetex.org website has a mention of the Ray Jet−Racer, describing the launch method, and another page on CO2-powered jet models. On rare occasion one of the Ray Models kits will appear on eBay...

Drug Cartels Terrorize Enemies with Weaponized Drones

Drug Cartels Terrorize Enemies with Weaponized Drones - Airplanes and RocketsHere is a big part of the reason the FAA is punishing R/C hobbyists with draconian rules and regulations. Thank a druggie near you. "Drug cartels attack enemies and spread terror with weaponized drones in U.S. Mexican police were clearing blockades placed by organized crime groups in El Aguaje, a western Mexico town that has become a battleground for drug cartels. Suddenly, authorities said, a drone flew over, dropping a gunpowder bomb and wounding two members of the Michoacán state police force in the arms and legs..."

Matchbox Fliers

Matchbox Fliers Article & Plans, April 1962, American Modeler - Airplanes and RocketsIt seems most every old time rubber-powered free flight model has been converted by someone to electric-powered radio control. The availability of motors and R/C airborne systems weighing in the grams - or fraction thereof - is making R/C flight for even the tiniest models possible. It would be interesting to see somebody convert these Matchbox Fliers, which appeared in the April 1962 issue of American Modeler magazine, to at least single-channel R/C using one of the nano-size radio systems available today. Heck, there's probably a way to even mount a camera to a model this small these days...

Miss Max Free Flight Plans

Miss Max Article & Plans, July 1961 American Modeler - Airplanes and RocketsPlans with minimum instructions for the Miss Max free flight model were published the July 1961 issue of American Modeler magazine. Bryant A. Thompson (AMA 2697 - USAF Team Member), of Wichita Fall, Texas, placed third in the Open Clipper event at the 1960 Dallas Nationals using his Miss Max cargo design. It lifted 40−½ ounces. The "300" ½A Free Flight and Clipper Cargo versions are both shown in the plans. Scaling factors for "300" (Class ½A), "450" (Class A), and "900" (Class B) model sizes are provided. A Cox Pee Wee .020 is drawn on the plans for the Cargo Clipper version. In the top view, note that the wing is shown "flattened" (without polyhedral). "Flat span" dimensions are what appear in the table.

Duro-Matic McCoy Red Head Advertisement

Duro-Matic McCoy Red Head Advertisement, November 1946 Air Trails - Airplanes and RocketsIf you didn't know that the famous McCoy Red Head engine was made by a firm named Duro-Matic Products Company, you're not alone. Duro-Matic made a lot of models and accessories in its early days, including tethered model cars, engines for airplanes, boats and cars. According to an article on The Internet Craftsmanship Museum website: "Starting in the late 1930's, Dick [McCoy] produced about 35 race car engines on his own before having them made by Duro-Matic Products Co. in Hollywood starting in 1945. From 1953 to 1956 the engines were made by McCoy Products Co. in Culver City before turning production over to Testors in April, 1956." Accordingly, this advertisement in a 1946 issue of Air Trails magazine appeared not long after Duro-Matic Products Co. began making the McCoy engines...

Northrop Aeronautical Institute

Northrop Aeronautical Institute Ad, November 1946 Air Trails - Airplanes and RocketsPer Merriam-Webster, the word "quiz" as a noun means: 1) an eccentric person, 2: a practical joke, or 3: the act or action of quizzing specifically - a short oral or written test. As a verb it means: 1) to make fun of - mock, 2) to look at inquisitively, or 3) to question closely. Since this "Quiz on Aeronautical Engineering Education" from a 1946 issue of Air Trails magazine is directed toward the reader, its content does not seem to meet any of the definitions. It can only really be called a "quiz" if it is directed toward the Northrop Aeronautical Institute, which it is. It is clearly a case of the reader asking the questions, not the reader being quizzed on his aeronautical knowledge. I point this out only because it seems like a deceptive technique for grabbing the reader's attention by implying a test of technical prowess - in which the kind of people who read this sort of magazine typically love to participate. Instead, it is merely an advertisement...

Rotating Detonation Engines for Rocket Propulsion

Rotating Detonation Engines for Rocket Propulsion - Airplanes and Rockets"These engines will allow upper stage rockets for space missions to become lighter, travel farther, and burn more cleanly. Researchers have developed a rocket propulsion system, known as a rotating detonation rocket engine, that will allow upper stage rockets for space missions to become lighter, travel farther, and burn more cleanly. Rotating detonations are continuous, Mach 5 explosions that rotate around the inside of a rocket engine. The explosions are sustained by feeding hydrogen and oxygen propellant into the system at just the right amounts. This system improves rocket engine efficiency..."

Bonanza Debonair Article & Plans

Bonanza Debonair Article & Plans, July 1971 American Aircraft Modeler - Airplanes and RocketsWebsite visitor Eduardo wrote to ask that I scan and post this construction article for the Beechcraft Bonanza Debonair. It appeared in the July 1971 issue of American Aircraft Modeler magazine. I am glad to do so for anyone, at no charge, as time permits. Usually, I am able to get requests completed within a couple days. If plans are still available through the AMA Plans Service, then only lower resolution versions are posted (typically 1500 pixels wide) in order to not cheat the AMA out of needed revenue. Besides, there are distortions in the scaled-up magazine version that would not be present in the AMA's reproductions from the originals. The AMA Plans Service will provide a version of the plans at a size different from the original, so, for instance, if you want a 48" wingspan rather than 60" like the one featured...

Penni Helicopter

Penni Helicopter from the January 1970 American Aircraft Modeler - Airplanes and RocketsThis article for the rubber-powered free flight Penni Helicopter, by John Burkam and Gene Rock, was scanned from my purchased copy of the January 1970 American Aircraft Modeler magazine. The Penni Helicopter is fairly unique in that it has a functional tail rotor to counter the main rotor torque rather than just a big flat vertical surface. It also features a flybar on the rotor head to help stabilize flight. Main rotor span is 16 inches. Because the plans spanned two pages, I had to adjust the size and alignment a bit to get halves to line up properly. The AMA Plans Service does not carry the Penni Helicopter, so if you need a larger version, e-mail me and I will send you a 4.5 x 3.0 kpixel version. You should be able to scale up the image below, though...

Starting Control Line Flying Scale

Starting Control Line Flying Scale, Annual 1960 Air Trails - Airplanes and RocketsThis "Starting Control Line Flying Scale" article in the 1960 Annual Edition of Air Trails magazine is still a good primer on how to go about getting into scale flying model competition. Some of the contest rules have changed over the decades since, but the basics are the same. The table of model sizes and engines might need to be adjusted for electric powered models, but in the scale world there are still many modelers who use internal combustion engines - especially in the large airplanes. A quietly humming motor does not give quite the same real-world affect as a screaming engine. Even with all the research going into full-scale electric aircraft, we're still many moons away from have a viable military fighter, transport, or commercial commuter. The drawing is by the famous Cal Smith (as is the cover image), but the text of the article is not attributed to any named author...

Find Your Birth Star

Find Your Birth Star - Airplanes and RocketsIf you ask most people what a birth star is, almost certainly he/she will relate it somehow to astrology. The thought makes me cringe. Although there really is no such thing as a birth star, there is such a thing as a star whose distance from Earth is equivalent in light-years to the day you were born. That means the light leaving the star actually began radiating in the direction of Earth within a few months of the day you were born. For instance, I was born on August 18, 1958, which was 54.5 years ago. All that's needed to find my birthday star is to find one that is 54.5 light-years away. Fortunately, there's an app for that. Per the Joint Astronomy Center website's birthday star finder: (the original website is gone) "Your birthday star is in the constellation Taurus...

Compact N-Gauge Train Layout

The Blattenbergers' Compact N-Gauge Train Layout - Airplanes and RocketsWhile living in Colorado Springs, CO, in the 1990s, our family decided to build a compact N-gauge model train layout that looked like the northwestern Nebraska landscape that we had driven through many time. It represents the old west that comes to mind from the Oregon Trail days, although that pre-dated the train routes of the day. An inexpensive Lionel N-gauge train set was purchased, along with a few extra sections of track. Since space was very limited, a 4' x 4' platform was used, and was cut out of 3/4" plywood in order to make it rugged enough to be moved around. Three sides were cut from the remaining 4' x 8' sheet. Unfortunately, digital cameras were not the norm then, so I didn't take a lot of photos throughout the process. Styrofoam sheets were cut and sanded to form the track underlayment, the hills, and tunnel, then gauze impregnated with a plaster mix was applied over top of it all. Trees and underbrush, the pond water, and faux grass...

Facts About Microfilm

Facts About Microfilm, May 1954 Model Airplane News - Airplanes and RocketsMicrofilm-covered indoor models is one (of many) aspects of model airplane building and flying that I've always wanted to try, but never found the opportunity. You might be tempted to think this is the exclusive realm of white-haired old men, and admittedly it nearly is, but when you look at contest coverage in the modeling magazines, it is heartening to see a good showing of youngsters. For that matter, the same holds true for just about all forms of model aircraft these days except for radio controlled airplanes and helicopters. As recently as a couple decades ago, radio equipment was too expensive for many younger modelers to buy, so those who aspired to hobbies involving airborne craft had to settle for free flight and control line. Now, the department store shelves hold no control line or free flight models, but a nice selection of miniature R/C helis and airplanes...

Virgin Galactic Flies to Edge of Space

Virgin Galactic Flies to Edge of Space - Airplanes and Rockets"Two pilots flew Virgin Galactic's SpaceShipTwo rocketplane to the edge of space Saturday over New Mexico on the first human spaceflight from the company's new home base at Spaceport America. Commercial astronauts Rick 'CJ' Sturckow and Dave Mackay were aboard the flight deck of Virgin Galactic's VSS Unity spaceship for the test flight. After release from Virgin Galactic's carrier aircraft VMS Eve at an altitude of about 50,000 feet (15,240 meters), the SpaceShipTwo rocketplane fired a hybrid motor Saturday for a minute-long burn to boost the ship above the dense atmosphere to a maximum velocity about three-and-a-half times the speed of sound..."

Early UAV Development

Early UAV Development - Airplanes and Rockets"Anyone familiar with Dahlgren history has almost certainly heard of Carl Norden and Dahlgren's role in the development of his famous bombsight. It's less well known that he came to Dahlgren two years before his first bombsight tests and almost five years before testing the first version of his famous bombsight in 1924. This earlier visit was related to the development and testing of a 'flying bomb' for the Navy. This work was an outgrowth of a project started by Elmer Sperry to build a gyro stabilized, unmanned airplane for the Navy. Several years after he came to the United States Norden went to work for Elmer Sperry ('Old Man Dynamite'), fell out with Sperry over patent rights..."

Here's the Stinson Reliant!

Here's the Stinson Reliant! - Article and Plans, May 1934 Flying Aces - Airplanes and RocketsFresh off the Flying Aces magazine press (in 1934) is this article and plans for a rubber-powered free flight Stinson Reliant model. The 26-inch wingspan craft drawn and built by author Avrum Zier is of customary construction with balsa sticks and Jap tissue covering. A carved cowl and wheel pants, and paper landing gear fairings make for a very nice look. There five plans sheets that can be scaled up or down to suit your needs. Send me an e-mail if you need higher resolution plans files.

Portable Control Line Aircraft Carrier Deck

Portable Control Line Aircraft Carrier Deck (March 1962 American Modeler) - Airplanes and RocketsHere is a clever control line airplane carrier deck design that derives it lightness from sparse construction and its compactness from making the modular components stowable within each other sort of like the familiar Russian matryoshka nesting dolls. Appearing in the March 1962 issue of American Modeler magazine, it is designed to accommodate a 60' circle, but slight modifications to the deck components can be easily made for other radii. Not shown in the plans but likely possible without sacrificing strength and rigidity would be to drill lightening holed in the 1"x6" and 1"x8" frame members...
