Dremel Model 381 Moto-Tool Kit & Instructions

Dremel Moto-Tool Model 381 Kit & Manual - Airplanes and RocketsThis Dremel Model 381 Moto-Tool Kit is the next generation after my Dremel Model 371 Moto-Tool kit that my Dremel Model 370 Moto-Tool was part of. Somewhere along the line I disposed of the plastic box that held the Moto-Tool and accessories, so I looked on eBay for a replacement. After many years of waiting, the closest I came was this Dremel 318 Moto-Tool Kit. It appears to be identical to the Model 371, only it came with the Dremel Moto-Tool Model 380. The Model 380 has ball bearings whereas the Model 370 uses brass bushings. This Dremel Model 381 Moto-Tool Kit appears to be in like-new condition and looks like it has never been used. Scans of all the manual pages are posted below in case you have been looking for them.

Cavalry of the Clouds

Cavalry of the Clouds, March 1937 Flying Aces - Airplanes and RocketsArch Whitehouse's air adventure stories with wily ballistics expert and ace pilot Kerry Keen (alter ego, The Griffon) are one of my favorite reads in the vintage Flying Aces magazines. While testing their amphibious Black Bullet over Long Island, aviator Kerry Keen (the Griffon) and mechanic Barney O'Dare spot a stolen experimental aircraft - a winged fortress capable of carrying tanks. When Barney vanishes mysteriously, Keen discovers his partner has been entangled in a plot to steal "Avalin," a revolutionary armor formula. The trail leads to kidnapped movie star Doreen Yardley, who unknowingly received the formula- all while protecting Keen's masked identity...

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...

Designing RC Helicopters

Designing RC Helicopters, March 1971 American Aircraft Modeler - Airplanes and RocketsJohn Burkam was one of the few true pioneers in free flight and particularly radio controlled model helicopters. His experiments date back into the 1940s. His rubber-powered Penni Helicopter appeared in the January 1970 issue of American Aircraft Modeler. Also, he covered the 1972 and 1974 helicopter Nationals competitions in American Aircraft Modeler. John was an engineer with the Boeing Company. His attention to detail and lack of fear in tackling design issue with numbers, graphs, and formulas is apparent in his work, although any type of design in previously unexplored or little explored areas of technology requires some degree of seat-of-the-pants guestimates. Both philosophies are present in this article. The "Super Susie" is powered by a Cox .049 Tee Dee engine, has four channels, and weighs in at around 2 pounds. That is pretty remarkable for early 1970s equipment. It's too bad someone doesn't produce an .049-powered R/C copter today...

Flite Kite  .049-Powered Box Kite

Flite Kite, April 1957 American Modeler - Airplanes and RocketsThere is an old adage about aircraft that says with enough power just about anything can be made to fly. The F-4 Phantom and F-104 Starfighter jets are prime examples. In 1957, kids and adults were still obsessed with flying machines and created all sorts of crazy craft. Flying dog houses, witches on brooms, flying doors, flying lawnmowers, and flying outhouses were popular novelty projects. Ken Willard even created a Flying Bandana. This Cox .049-powered box kite doesn't fall into the same category as an F-4 Phantom, but it does apply as far as making anything fly if you hang an engine on it. Although author McLarty claims you can adapt a toy store box kite ...

Milestone in Mankato: Ninth Rocketry Nats

Milestone in Mankato: Ninth Rocketry Nats, from January 1968 American Aircraft Modeler - Airplanes and RocketsWhenever I look at articles like this one in American Aircraft Modeler magazine of the 1967 model rocketry nationals (NARAM-9) showing people from 40+ years ago, I always wonder what they are doing today. Kids that were 16 in 1967 are 60 today! Many of the adults, if they are still living, are in their 80s. Are they still flying model rockets? Are they in good health? Has life been good to them? Time can be a cruel master, or it can also be a benevolent guardian. But, at the time nobody was thinking about where they would be or what they would be doing in the year 2011; their only concern was the competition at hand and having a good time. Note the number of Ph.Ds in the crowd! Back in the day, model rocketry was a big part of preparing young men (and a few young women) for a career in astronautics...

Wee Bee Article & Plans

Wee Bee Article & Plans, November 1950 Air Trails - Airplanes and RocketsThe Wee Bee was at one time considered the world's smallest man-carrying aircraft. It had an 18-foot wingspan and weighted 215 pounds without pilot. Lloyd Hunt's model of the Wee Bee is designed for either free flight or control line. For C/L it is powered by an .049 engine, and for F/F it uses an .020 engine. Its 22" wingspan makes it about 1/10th scale. Construction is built-up fuselage, wing, and tail surfaces with balsa sheeting over all. If you are looking for an unusual scale model that will not require a lot of detail to make it look authentic, the Wee Bee would make a good subject ...

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...

FCC's Secrecy of Communications for CB Radio

Editorial: FCC Secrecy of Communications CBs, May 1969 American Aircraft Modeler - Airplanes and RocketsThis is a very interesting article about the FCC's "Secrecy of Communications" rules. Manmade radio interference (QRM in Ham lingo), has been a problem since the early days of wireless communications. You might convincingly argue that it was worse at a time when many transmitters were of the arc type that basically spewed out a mess of RF energy within a specified bandwidth (very wide compared to today) to signal the presence of a "dit" (a digital "1"), with the absence of a signal being a "dah" (digital "0"). Filter technology for both the transmit and receive sides was also poor, allowing unintentional RF noise to be sent over the air and to find its way into the detector circuits. The Federal Communications Commission (FCC), first formed in 1934, nearly four decades after Guglielmo Marconi first demonstrated his wireless set in 1896. Sometime around 1952, the FCC allocated a half dozen frequencies in the 27 MHz for radio control (R/C) model use, mixed within the existing citizens band (CB) radio channels. As you might imagine, interference problems were rampant, especially near metro areas and highways with heavy truck traffic. This editorial in a 1969 issue of American Aircraft Modeler magazine reports on just how bad things had gotten, especially that caused by operators using faulty and/or illegally modified transmitters, and even by malicious intentional attempts to "shoot down" model airplanes by keying transmitters in the vicinity of flight activity. In 1965, the FCC allocated...

Peanuts Bobblehead (Nodder) Collection

Peanuts Bobblehead (Nodder) Collection - Airplanes and RocketsThis is a complete set of the Peanuts Bobblehead (Nodder) figures. They're not perfect, but in pretty good condition. Over time, our Peanuts collection of memorabilia has grown 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. The "Peanuts: The Art of Charles M. Schulz" book was very helpful in identifying which Peanuts memorabilia items ...

Spartan School of Aeronautics Advertisement

Spartan School of Aeronautics Advertisement, December 1954 Air Trails - Airplanes and RocketsNowadays know as Spartan College of Aeronautics and Technology, the Spartan School of Aeronautics was founded in 1928 in Tulsa, Oklahoma, by oil magnate William G. Skelly. Skelly believed air transportation was the way of the future and to be successful would require skilled aircraft technicians and pilots. Spartan claims to have trained more than 100,000 technicians and pilots for careers in the aeronautics industry. They now have branches in Denver, Colorado, and Los Angeles and Inland Empire, California. The Spartan Black Cat logo, which includes the number 13, and the slogan "Knowledge and Skill Overcome Superstition and Luck," was the original insignia of the Spartan College Dawn Patrol. The fact that Spartan School of Aeronautics began only a year before of the stock market crash of 1929 and survived the ensuing decade-long Great Depression and Dust Bowl years is a testament to its tenacity. This advertisement appeared in a 1954 issue of Air Trails - Hobbies for Young Men magazine...

Sketchbook: Tips and Tricks

Sketchbook from March 1957 American Modeler Magazine - Airplanes and RocketsThis Sketchbook was scanned from the March 1957 issue of American Modeler magazine, published by the Academy of Model Aeronautics. Most building tips are timeless. Even in this era of ready-to-fly (RTF), almost-ready-to-fly (ARF), bind-and-fly (BAF), etc., there are still many modelers who build their own aircraft. Nearly all top tier competition fliers build their own models, as do aficionados of vintage (aka old-timer) models. Some guys just would rather build than buy a pre-build airplane, whether from a kit or from plans. I like the idea of using a sharpened bullet cartridge for boring lightening holes in ribs, tail surfaces, etc., rather than using a drill bit. The tip about using a slot in the bellcrank for the flaps of a control line stunt models seems a bit iffy, since it can permit oscillations (fluttering) during normal flight...

Burgess Salutes United on 20th Anniversary of Transcontinental Airmail

Burgess Salutes United on 20th Anniversary of Transcontinental Airmail, January 1941 QST - RF CafeThis thankful commemoration of the 20th anniversary of U.S. Air Mail service from Burgess Battery Company, which appeared in a 1941 issue of QST magazine, encompasses most of my major lifetime interests. First and foremost, from my earliest memories, is a love of airplanes (and all things that fly for that matter). A DC−3 (my favorite multi-engine propeller plane) is shown in one of the photos as is a Ford Trimotor, which Melanie and I have flown on. Next comes the electrical, electronics, and radio communications aspects, which encompasses the aircraft wiring ...

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.

Bristol "170" Freighter Article & Plans

Bristol "170" Freighter Article & Plans - 1961 Annual Edition American Modeler - Airplanes and RocketsWebsite visitor Robert C. wrote to request that I post the article and plans for the British Bristol "170" Freighter that appeared in the 1961 Annual edition of American Modeler magazine. This control line version has a 40" wingspan and is powered by a pair of .049s for scale-like flight characteristics or a pair .09s if you want aerobatics. Diesels are shown installed in the original. The fuselage, wing, and tails surfaces are all built-up and sheeted with balsa, so she is a sturdy bird. As with most of these vintage models that used glow engines, conversion to electric can be easily made, and lightening of the structure can be safely done since motors do not create the extreme vibration loads of internal combustion engines. For instance, the balsa sheeting of the entire wing could be reduced to only the root area at the fuselage, and then maybe add a stringer or two along the leading edge top area...

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...

The Stanzels of Schulenburg

The Stanzels of Schulenburg, January 1961 American Modeler Magazine - Airplanes and RocketsA couple years ago I posted an article about the Victor Stanzel ElectroMic "Copter" Tethered Helicopter that I had bought on eBay. It was just like the one I had as a pre-teen in the 1960's. If memory serves me correctly, I also had one of the ElectroMic Flash Tethered Airplanes as well. Someday I'll probably buy one of those on eBay. The webpage hyperlinked above has a video embedded that tells the story of the Stanzel Brothers' Model Airplane Museum. You will be amazed at all the types of models they produced - powered airplanes, gliders, helicopters, flying saucers. They were a couple of the earliest pioneers in manufacturing ready ...

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 ...
