Bill Gaylord's Guillow's R/C Electric Conversions

Bill Gaylord's Guillow's R/C electric conversions - Airplanes and RocketsMr. Bill Gaylord has been gracious enough to allow me to post photos and information about his fine Guillow's free-flight model airplanes that he converted to electric powered R/C. The level of craftsmanship is incredible both in the frame-up and the covering and finish. You can find lots of photos and details of the build on the RCGroups bulletin board. I do not see whether he has ever flown any of these models. My guess is that with the structural beefing up required to support the motor, battery, and R/C gear results in a high wing loading. I personally would never dare risk these models by trying to fly them! They would all spend their days as hanger queens - display only...

An Experiment with Gravity

An Experiment with Gravity, January 1970 Popular Electronics - Airplanes and RocketsThis is pretty cool. If I owned a good receiver, I would definitely give it a try. In 1970 when this Popular Electronics magazine article was written, a lot of Hams were still using vacuum tube receivers so the recommendation to let the equipment warm up for several hours prior to making the fine frequency adjustments was good advice. Nowadays the warm-up time and stability of receivers should permit 30 minutes or so to suffice (even ovenized frequency references need time to stabilize when first powered up). Unless I missed it, the author does not explicitly state that the frequency change measured over time is due to gravity acting on the mass of the crystal reference, but I suspect that is his intention since part of the experiment involves disconnecting the antenna and shielding the receiver from outside interferers. Over a lunar month period (29.5 days) we experience...

World's First Astrogator Rocket

World's First Astrogator Rocket, March 1965 Science & Mechanics - Airplanes and RocketsLucky thing for budding amateur rocketeer Allen Wechter that some of the PETA (formed in 1980) crazies were not around in 1965 when this "World's First Astrogator" article appeared in Science and Mechanics magazine. Otherwise, he surely would have been targeted as an animal abuser when he claimed to be the first person to launch an alligator into [sub]space. The beast was sent to an altitude of 8,500 feet, whereupon it floated gently down via parachute. The story mentions that it landed two miles downwind, which in Flushing, New York, even in 1965, would have been a mighty densely built-up region of Long Island, near New York City. He's lucky to have retrieved it! Master Wechter claims the 'gator was "unscratched and in excellent physical condition," but I'm guessing he was emotionally scarred for life ;-)

Aeronca C-3  Kit by Sterling Models

Aeronca C-3  Kit by Sterling Models - Airplanes and RocketsI remember as a kid in Mayo, Maryland, tying a string to the nose of my Sterling Aeronca C-3 model and towing it behind my Huffy bicycle - with a banana seat and a sissy bar - up and down the street in front of my house. It would weave and dodge back in forth in a sort of gyrating motion a few feet off the ground and then settle into a fairly decent landing. Assuming the Aeronca C-3 met the same ultimate demise as most of my models of the era, it probably succumbed to an airframe failure after early success fed the human desire to go higher and faster than the last time. One thing that stands out in my mind about the Aeronca was that it was one of the most complex models I had attempted to date - especially with building the wing support assembly on top and adding all the flying wires. The kit shown here was purchased on eBay. It is yet another addition to my collection of model items I had as a kid. None of my original equipment survived...

Counted Cross Stitch Orbis Terrae Compendiosa Descriptio

Counted Cross Stitch Orbis Terrae Compendiosa Descriptio - Airplanes and RocketsBack when Melanie had more time (around 1984), she made a lot of counted cross stitch pictures. This one remains her most ambitious project ever - a large nautical map of the ancient world, fashioned after the works of famed cartographer Gerard Mercator and titled with "Orbis Terrae Compendiosa Descriptio," which is, loosely translated, Latin for "A Comprehensive Description of the World." Melanie's work was done on 22-count fabric, and measures approximately 13" by 8" (not including white border). Such a fine effort needed a special frame, so I set about making a custom 23" by 17" frame out of teak wood bought at World of Hardwoods in Baltimore. The fancy fluting was done on my Craftsman radial arm saw with the molding head. Teak, as you might know, is used extensively on boats because it weathers well. It is an oily type wood that starts out life with a shiny golden patina...

Glass-Plastic Aircraft Challenge the "Heat Wall"

Glass-Plastic Aircraft Challenge the "Heat Wall", June 1953 Science and Mechanics - Airplanes and RocketsThe type of glass referred to in this 1953 Science and Mechanics magazine article is not the solid sheet type made from sand (silicon), but fiberglass. It has strands of glass mixed into the plastic weave, hence the name. It is the glass component that causes itching as it pricks your skin. Breathing it into your lungs is dangerous as the minute particles of glass can lodge in the tissue. Typical of the era, the workers shown handling the fiberglass have no protection for eyes, nose, mouth, or skin. Fiberglass ended up not being the material hoped for because it ultimately could not stand up to the extreme structural and thermal loads typical of high speed aircraft. It was also not tolerant of being exposed to intense sunlight while sitting on a tarmac. The few commercial and homebuilt fiberglass airplanes need to be painted white to reflect as much ultraviolet light as possible to prevent delamination and deterioration of the components...

Model Aircraft Covering Weight Comparison

Model Aircraft Covering Weight Comparison - Airplanes and RocketsWhen deciding which type of covering material to apply to a model airplane structure, it would be helpful to have a table of covering density for comparison. Here is such a table which shows, for instance, that 21st Century Fabric is the heaviest type of covering you can use. MicroLite covering is the lightest weight. Not shown are most doped or painted coverings because finished weights are so dependent on substrate type (silk, Silkspan, tissue, etc.), paint or dope type, and number/thickness of coats. To calculate the covering weight, multiply the density by the total surface area of your model. Unfortunately, most of these coverings are no longer manufactured, but a lot of it can still be found on eBay...

Peck-Polymers Is Back in Business

Peck-Polymers Is Back in Business !!! - Airplanes and RocketsPeck-Polymers has been around for as long as I can remember, which was in the late 1960s to early 1970s, when I would have bought my first aeromodeling magazine (we relied on magazines back then for information since Al Gore had not yet invented the Internet). In fact, Peck-Polymers was founded in 1971 by engineer and free-flighter Bob Peck. According to the "About" page on their website, Bob designed many of the models in the original Peck product line. He and his wife Sandy we soon kitting designs by Bill Hannan, Bill Warner, Dick Baxter and many others. Peck-Polymers has also long been at the forefront of design and engineering of the many small parts that are so critical to free flight rubber airplanes, such as the bearings and prop shafts. Bob passed away in 1991, and his wife Sandy kept the company going until late 2007 when she sold it to Tim Goldstein of A2Z Corp. (now defunct) Tim created the laser-cut kits. In January of 2015, Chuck Imbergamo of Wind-It-Up Enterprises took ownership of the company and thankfully is committed to carrying on the tradition of producing Peck-Polymer kits and accessories...

Radio Control News

Radio Control News, May 1954 Model Airplane News - Airplanes and Rockets1954 was just a decade after World War II, during which time the Army Signal Corps introduced a method of printing - or etching - metallic circuit conductors on an insulator substrate, and thus was born the printed circuit board (PCB). The first boards used a phenolic-paper laminate, which is the shiny brown substrate material that is still found in some industrial applications like motors and control panels. Ferric chloride was used to etch away the copper foil not masked off with photoresist chemicals. I made many crude PCBs using a resist ink pen to draw circuit traces and component mounting pads, then etched away the exposed copper with ferric chloride purchased at Radio Shack. This line from the article is reminiscent of people who remarked similarly about the first televisions and computers: "One of the first questions that arises is: 'What good is it and what do I gain by using it?'" Printed inductors were already being used, as the photo shows...

New Balloons Explore Roof of the Airways

New Balloons Explore Roof of the Airways, May 1948 Popular Science - Airplanes and RocketsAs a kid living in Holly Hill Harbor, Maryland, I managed to find many uses for those thin plastic bags that protected garments returned from the dry cleaner. The two most often were for parachutes and for filling with hot air to use as a balloon. I'd tape my mother's sewing thread to a cut-out circle for a parachute, then tie a small rock to the ends of the "shroud lines." Then, I'd fold it and wrap the lines around it like with my Estes rockets, and chuck it as high into the air as possible. Only when my arm got sore did the repetitions stop. The hot air balloon exercises were not very impressive. Forming a two-dimensional piece of plastic into a three-dimensional sphere(oid) resulted in a less than optimal enclosure, with excess material that only added weight without adding volume for hot air. A hair dryer borrowed - usually without permission - provided the hot (more like warm) air for buoyancy. The thin plastic easily wrinkled if the end of the hair dyer touched it...

Find the Scale Wingspan & Area

Find the Scale Wingspan & Area - June 1969 American Aircraft Modeler - Airplanes and RocketsDave Platt - aka "Mr. Scale" - is one of the world's most accomplished scale model airplane builders and flyers. He somehow manages to turn out magnificently detailed scale models year after year. If you haven't seen his "Platt's Laws of Scale Modeling," derived from his decades of experience, you'll want to do so. He has built and flown his scale models in the realms of free flight, control line, and radio control, using internal combustion engines with propellers, ducted fans, and turbine jets for propulsion. There might be someone somewhere equally qualified to comment on scale airplane modeling, but none more qualified. When this "Find the Scale Wingspan & Area" article appeared in a 1969 issue of American Aircraft Modeler magazine, slide rules were the de rigueur...

Thimble Drome Cox Prop-Rod Air-Powered Car

Thimble Drome Cox Prop-Rod Air-Powered Car - Airplanes and RocketsThe Prop-Rod car was one of the earliest models produced by L.M. Cox Manufacturing. For many years the models went by the trade name of Thimble Drome, but later were know simply as Cox Models. It was featured in magazine advertisements as early as 1961 when it appeared in American Modeler. The Prop-Rod came with a Babe Bee .049 engine mounted with its cylinder inverted, which could make starting it difficult since fuel could pool in the glow head. As with airplanes having inverted cylinders, starting it was often done by holding the model upside down. It was designed to run either on a tether stretched along a sidewalk, on a tether mounted in the center of a circle...

Airmen of Vision Design Competition

Airmen of Vision Design Competition, February 1949 Air Trails - Airplanes and RocketsWhen Air Trails magazine was running these airplane design contests in the 1940s and 1950s, the world was fascinated with the concept of flight. Revolutionary airplanes like the Douglas DC−3, introduced in the 1930s, opened up the skyways to middle class citizens, and a plethora of surplus World War I biplanes made learning to fly affordable. Great advances were made in aircraft design and manufacturing during World War II, and those lessons were rapidly being applied to civilian aircraft to make flying accessible to average people. Model aviation was also a huge interest to the young and old alike. Static display models, simple free flight gliders and propeller driven models, control line models with screaming internal combustion engines (ICE) were the passions of hundreds of thousands - maybe millions. Most enthusiasts built models from kits or plans, but others preferred to design and build their own models. They were the visionaries...

How High™ Electronic Altimeter Teardown

How High™ Electronic Altimeter Teardown Report - Airplanes and RocketsWinged Shadow Systems has developed a solid state electronic altimeter called the How High™ that plugs into a spare receiver channel for power, and provides altitude readings between 50 feet and 7,000 feet above ground level. The heart of the system is the SM5420 pressure sensor, by Silicon Microstructures. It is a micromachined structure molded in an 8-pin SOIC plastic package. Here is the datasheet. Per the manufacturer, "The SM5420C is a small outline SO-8 packaged pressure sensor. The sensor uses SMI’s SM5108C micromachined, piezoresistive pressure sensing chip that has been optimized to provide the highest possible accuracy for a package of this size..." News Flash: I set a personal thermalling altitude record of 1,267 feet in my 85% Aquila glider on May 23, 2024!

The BOMARC IM-99 Story

The BOMARC IM-99 Story, August 1958 American Aircraft - Airplanes and RocketsIs the BOMARC an airplane or a rocket? If it is an airplane, then it is the pilotless type (aka "drone"). If it is a rocket, then it is the ultimate in controlled trajectory hardware - at least in its day. The DoD referred to it as a surface-to-air guided missile. The name is a combination of "BOeing Airplane Company" and "Michigan Aeronautical Research Center." Clever, non? If memory serves me correctly (it's been 30+ years), the AN/TPX-42 IFF (Identification Friend or Foe) secondary radar system (built by Gilfillan) I maintained as an air traffic control radar technician reserved a special "X" bit in its data packet to designate the BOMARC - and maybe other guided missiles. That might have been a military secret at the time, because the Air Force instructors acted like they were divulging proprietary information when discussing why that bit was present in an otherwise...

Radio Control on the Citizens Band

Radio Control on the Citizens Band, March 1952 Radio and Television News - Airplanes and RocketsRadio control (R/C) of a model doesn't get much simpler than the transmitter and receiver circuits shown in the schematics of Figure 2. Of course the cleanness of the transmitted signal and the selectivity of the receiver of that signal leaves a lot to be desired. In 1952 when this article appeared in Radio & Television News magazine, the airwaves weren't cluttered with wireless communications devices, but given that these radio systems were sharing the electromagnetic spectrum with Citizens Band (CB) radio, the chances of getting "shot down" from nearby operators was pretty high if you lived within a few miles of where CB'ers were communicating. More sophisticated R/C equipment was available from commercial manufacturers, but this system targeted the do-it-yourself types and those with limited hobby budgets...

Victor Stanzel Electromic Tethered Helicopter

Victor Stanzel Electromic Tethered Helicopter - Airplanes and RocketsFor most people my age (born in 1958), the first experience with a "real" flying model helicopter was this ElectroMic "Copter" by Stanzel. I finally acquired one via eBay for a fair price. The "Copter" uses two D-cell batteries in the plastic handle to power a motor, also in the handle, which in turn drives the center wire of a coaxial cable that connects to the helicopter rotor. Flying the Copter is a matter of pressing the power button and then manipulating the handle to direct the model in flight. With fully charged batteries, the helicopter generates a lot of lift and requires angling the control cable downward to prevent the thing from performing the equivalent of a wingover. Forward and reverse flight involve angling the controller left and right. After a few moments of practice, precise control is fairly easy...

How to Build Better Wings

How to Build Better Wings, July 1962 American Modeler - Airplanes and RocketsHal deBolt was a well known and respected model aircraft designer in the early days of radio control. By 1962, when this "How to Build Better Wings" article appeared in American Modeler magazine, there were some proportional radio systems coming on the market, but a lot of fliers still used escapement, galloping ghost, or reed systems. With somewhat limited control , having an airplane that was inherently stable or neutrally stable was important for success. Negative stability usually meant disaster. One way to minimize airframe related issues is to build on a well-designed jig - especially for the wing and tail surfaces. Even today's laser cut, perfect fitting kit parts are of no use in obtaining a true airframe if the surface they are built on is twisted or bowed. This article offers a simple jig that can be used for building any normal wing...

Air Progress: Development of Gun Turrets

Air Progress: Development of Gun Turrets, February 1949 Air Trails - Airplanes and RocketsPilots of the very first airplanes used for military purposes simply fired pistols and rifles from their open cockpits toward ground targets, and even other airborne targets (airplanes and balloons). Soon thereafter, machine guns were mounted to the upper wing and/or wing struts of biplanes. Once synchronization mechanisms were developed to permit firing through the propeller, guns were mounted directly in front of the cockpit, on the fuselage, giving the pilot the advantage of directly sighting for firing. When the target is large and/or the size of the ammunition is large enough to inflict significant damage regardless of where it hits, then being able to draw a visual bead on the sweet spot is not as important. Next came separate gunners who were stationed above, below, in front of, and behind the pilot, depending on the design and size of the ship. The gunner had freedom of movement to move the gun around relative to the way the airplane was pointing, and he was not encumbered with having to fly the plane at the same time ... Master artist Douglas Rolfe provided this group of drawings representing the evolution of aircraft gun turrets. It appeared in a 1948 issue of Air Trails magazine...

Steve Wooley's Control Line Argus

Argus Article & Plans, August 1961 American Modeler - Airplanes and RocketsWebsite visitor Mark Radcliff (yes, THE Mark Radcliff, of 75-77-79-81 USA F3a RC Aerobatic Team fame, and until recently, VP of that AMA's District III) wrote to request that I scan the article for Steve Wooley's control line Argus, which, appeared in the August 1961 American Modeler magazine. The Argus was the star of the 1960 world championships in Hungary. Note the unique wing construction where rather than using full ribs, upper and lower outlines are used that sit over and under the beefy solid wing spar. The entire article is very short...

Air Progress: The Hawker Story

Air Progress: The Hawker Story, October 1950 Air Trails - Airplanes and RocketsEven when you are supremely talented as both an artist, researcher, and writer, as was Douglas Rolfe, producing the infographics, paintings, and articles like this 1950 Air Trails magazine piece for the "Air Progress: The Hawker Story" feature, requires an enormous amount of time and effort. Unlike today where most of the information (accurate or not) you want is available on the Internet, back in Rolfe's day, a library of books and magazines was needed to assimilate so much information on a single subject - in this case the lineage and evolution of the Hawker line of aircraft from its beginnings in 1912 under the name of Sopwith. In 1950, Hawker's newest airplane was the P-1050 jet (c1949), which followed Tempest (c1947) Typhoon (c1940), which became famous during World War II. Hawker merged with Siddeley (Hawker Siddeley Aircraft) in 1963. Their latest model is the Hawk (now BAE Systems), introduced in 1976...

1955 Air Force Model Airplane Championships

Air Force Modeling, Model Annual 1956 Air Trails - Airplanes and RocketsThe 1956 Annual edition of Air Trails magazine reports here on the 1955 Air Force Model Airplane Championships held at Travis Air Force Base, in California. Check out that B-29 control line model entry, and then see this B-29 model inherited by Boyd Steffe. Back in the good 'ole days, the U.S. armed forces spent taxpayer money supporting sporting events and hobby pursuits. It helped increase morale, esprit de corps, technical prowess, physical fitness, and very importantly, it promoted the service as a career and lifestyle. Both the Air Force and the Navy were heavily into model aviation by sponsoring competitions on bases worldwide. The Navy was a prime sponsor of the Academy of Model Aeronautics' Nationals competition for many years, using its exposure to young men as a recruitment effort. Today, sadly, such activity is looked upon by our Woke armed forces as White Privilege and money is instead applied toward gender change operations and lifelong medical and psychological support...

Fox 15x Engine

Fox 15x Engine, November 1961 American Modeler - Airplanes and RocketsFox model airplane engines had a reputation for ruggedness and contest-winning performance, but were also notoriously difficult to get started - at least without an electric starter. In 1961, when this full-page advertisement appeared in American Modeler magazine, electric starters were not in many modelers' field boxes, and particularly those owned by youngsters whose modeling budget came from meager allowances and paper routes. Born in 1958, I was 15 or 16 years old before being able to afford the luxury, and I remember relentlessly flipping the propellers on my Fox 15 and Fox 35 control line engines. Half the time when they started, they were running backwards and had to be stopped with a rag thrown into the prop, then the process started over again. Ugh. ...but I digress. Fox prided itself on their use of Meehanite iron for the piston. Per Wikipedia: "Meehanite is a trademark for an engineering process to make a range of cast irons produced under specific and carefully controlled conditions to precise internationally recognized specifications." I don't know what the difference is between the standard Fox engines and the "X" series. My Fox 15 and Fox 35, which I still have, are the standard non-X variety...

Bilgri Patching and Covering Methods for Microfilm

Bilgri Patching and Covering Methods for Microfilm, March 1971 American Aircraft Modeler - Airplanes and RocketsIndoor airplane models covered with microfilm seem to have always been for a very particular, dedicated group of modelers who possess the patience, steady hands, and eyesight (aided or not) to build and maintain very delicate structures. A directed sneeze can literally blow them to pieces. It is an aspect of aeromodeling into which I have never ventured. Mr. Joseph Bilgri, AMA #4393, was a contest-winning pioneer of the craft. The AMA History Project has a biography of Joe that is worth reading if you have an interest in indoor modeling. Of course today, with the advent of nano-size radio controlled and free flight models, the realm of indoor flying has increased considerably beyond wire-framed surfaces covered with bubble-thin sheets of microfilm. This 3-part series on indoor models begins with a construction article and ends with proven methods for successfully repairing damage. It appeared in the March 1971 issue of American Aircraft Modeler magazine...

Boeing's C-137 Jet Stratoliner

Boeing's C-137 Jet Stratoliner, July 1954 Popular Science - Airplanes and RocketsBoeing's Stratoliner was America's answer to Britain's The de Havilland DH.106 Comet commercial airliner. The Comet's maiden flight occurred on July 27, 1949, and it entered into commercial service with British Overseas Airways Corporation (BOAC) on May 2, 1952. This 1954 Popular Science magazine article reported on the first test flight of the Stratoliner. The article is not clear what its production designation would be, but the best information I can find, based on maiden flight dates, indicates it was the Boeing 367-80, which became the basis for the Boeing 707. The Wikipedia entry shows the factory-roll-out photo included in this article. There was also a Boeing C-137 Stratoliner military version. While Boeing's top test pilot Alvin "Text" Johnston is mentioned in the article, what is not mentioned is the unauthorized barrel roll he performed in the Stratoliner during a demonstration flight over Lake Washington, near Seattle, with the company president watching from his yacht!

How the New 200 Inch Telescope Works

How the New 200 Inch Telescope Works, April 1938 Boy's Life - Airplanes and RocketsThe [George Ellery] Hale 200−inch telescope saw first light (first official observation) atop Palomar Mountain, in southern California, on January 26, 1949. That was a decade after this early report on its planning appeared in a 1938 issue of Boy's Life magazine (the official publication of the Boy Scouts of America, BSA). It held the title of the world's largest telescope until Russia commissioned its 605 cm (238 in.) BTA-6 in 1976. As of this writing, the telescope with the largest light collecting capacity is the Large Binocular Telescope (LBT) on Mount Graham, in the Pinaleno Mountains of southeastern Arizona. When using both 330 inch mirrors, the LBT has the same light-gathering ability as a 464 inch single telescope and the resolution of a 897 inch wide one...

Solar Eclipse from Greensboro, NC, April 8, 2024

Solar Eclipse from Greensboro, NC, April 8, 2024 - Airplanes and RocketsOn April 8, 2024, one of the best total solar eclipses of the last century crossed the United States from Texas to Maine. Because the moon was near its closest orbital point to the Earth, and the Earth was about midway between its orbital apogee and perigee, the sun appeared relatively small and the moon appeared relatively large. That combination caused the moon's shadow to be very wide across the face of the Earth. Note in the NASA eclipse map at the right how much narrower the path of totality was for the August 17, 2017 eclipse. Maximum eclipse for this location was just shy of 81%. That was enough to cause an eerie feel in the sky, but it was nowhere near dark. Let me state that when I first became aware of this solar eclipse, it was sometime around 2016, when I was living in Erie, Pennsylvania. Due to scheduling issues, Melanie and I decided to not travel to South Carolina to view the August 21, 2017 eclipse, figuring we would have a front-row seat to it on April 8, 2024, from our house, which was only a few miles from the center of the path of totality. Life happened, and we ended up moving back to North Carolina in 2022. Because hotel rooms just about anywhere in the path of totality were in the $300+ per night range, we stayed here and missed totality...

Science Knowledge from April 8th Solar Eclipse

Science Knowledge from April 8th Solar Eclipse - RF Cafe"When a rare total solar eclipse sweeps across North America on April 8, scientists will be able to gather invaluable data on everything from the Sun's atmosphere to strange animal behaviors - and even possible effects on humans. It comes with the Sun near the peak of its 11-year solar cycle, setting the stage for a breathtaking display: The corona will glow spectacularly from the Moon's silhouette along the path of totality, a corridor stretching from Mexico to Canada via the United States. Total solar eclipses offer 'incredible scientific opportunities,' NASA Deputy Administrator Pam Melroy told a press conference this week about the celestial event. The U.S. space agency is one of the institutions at the ready for the eclipse, with plans to launch so-called 'sounding rockets' to study the effects on Earth's upper atmosphere. Here is a look at what researchers are hoping to learn from the upcoming eclipse. 'Things are happening with the corona that we don't fully understand,' she said. The heat within the corona intensifies with distance from the Sun's surface - a counterintuitive phenomenon that scientists struggle to fully comprehend or explain..."

World's Smallest, Lightest, and Fastest Fully Functional Micro-Robots

World's Smallest, Lightest, and Fastest Fully Functional Micro-Robots - Airplanes and Rockets"Two insect-like robots, a mini-bug and a water strider, developed at Washington State University, are the smallest, lightest and fastest fully functional micro-robots ever known to be created. Such miniature robots could someday be used for work in areas such as artificial pollination, search and rescue, environmental monitoring, micro-fabrication, or robotic-assisted surgery. Reporting on their work in the proceedings of the IEEE Robotics and Automation Society's International Conference on Intelligent Robots and Systems, the mini-bug weighs in at eight milligrams while the water strider weighs 55 milligrams. Both can move at about six millimeters a second. 'That is fast compared to other micro-robots at this scale although it still lags behind their biological relatives,' said Conor Trygstad, a PhD student in the School of Mechanical and Materials Engineering and lead author on the work. An ant typically weighs up to five milligrams and can move at almost a meter per second..."
