  1. The Academy of Model Aeronautics leadership team is hard at work making sure lawmakers in Washington, DC, will ensure that AMA members will continue to legally fly RC aircraft. It is so important that the RC modeling community has a strong voice in Washington! Here’s what the AMA has to say about the FAA’s proposed rulemaking: Chad Budreau, Executive Director at the Academy of Model Aeronautics (AMA), the world’s largest community-based organization whose members fly model aircraft for recreational and educational purposes, today issued the following statement in response to the FAA’s notice of proposed rulemaking on the Operation of Small Unmanned Aircraft Systems over People and advance notice of proposed rulemaking on Safe and Secure Operations of Small Unmanned Aircraft Systems. “The proposed rulemakings on flying over people, night flying, and safe and secure operations are a step toward opening up the airspace for more commercial UAS operators. For model aircraft hobbyists, however, we do not anticipate these rules will have a significant impact on our existing guidelines for safe and responsible operation. “Model aircraft flights over people are currently not allowed under AMA’s community-based safety guidelines. We believe this is a sound and proven safety guideline for all recreational UAS operators. At the same time, we understand that some commercial applications present the need for UAS to fly over people for effective and efficient operations. We believe these operations should be allowed, provided they can be done safely and any potential risk to people on the ground is appropriately mitigated. “In addition, AMA’s safety guidelines allow night flying as long as a lighting system that provides the pilot with a clear view of the model’s attitude and orientation at all times is in place. We believe this policy continues to make sense and, at first glance, is similar to what the FAA is proposing. “AMA’s safety guidelines also address several of the questions raised in the ANPRM for Safe and Secure Operations of Small UAS. For example, according to the safety guidelines, model aircraft are not allowed to be operated closer than 25 feet away from an individual except for the operator, with few exceptions. AMA also has varying guidelines for model aircraft with different capabilities. “Lastly, and perhaps most importantly, AMA recognizes that one of the FAA’s top priorities is to put remote identification rules in place to better facilitate the integration of UAS into the nation’s airspace and address security concerns. We continue to ask for FAA collaboration in adopting remote identification requirements that reflect the operational use of UAS – model aircraft, under AMA’s safety programming, pose no new risk to the airspace, therefore the remote identification rules for model aircraft operations should be more flexible.” In 2016, AMA President Rich Hanson participated in FAA’s Micro UAS Aviation Rulemaking Committee, which made recommendations on the regulatory framework for small UAS flights over people. At that time, we expressed some concerns about allowing recreational UAS flights over people primarily because of safety. In addition, we were concerned that the public would be sensitive to drones flying over their heads – concerns that are still valid today. AMA’s full safety guidelines are available here.

  2. Bracketry is an old term referring to making small brass brackets for scale model airplanes. Mostly for attachment points where you need a solid hard-point for the attachment of wing struts and rigging wires for biplanes and other wire braced airplanes. For the longest time, this was all done by hand, using fine-toothed coping and hack saws, files and more recently, Dremel Moto-Tools with grinding bits and cutoff discs. Once the flat layout part has been cut to shape, it is sanded and filed smooth, drilled and bent to shape. Well, the newest technique is milling with precision CNC systems and this really speeds the process along. When you want to make brackets, first you have to figure out what it is going to look like and today we draw with CAD, then print out the drawings and transfer the shape to your brass sheet material. This is typically 1/16 inch thick (0.0625 in.), and the old fashioned way is to use a dykem layout fluid to coat the metal and use a sharp fine point scribe to mark the cut lines. Today a wide tip Sharpe pen can do the same thing. This process is much more precise than trying to draw with a pencil the cut and trim lines on the shiny surface of brass (or steel) sheet metal. With bench top hobby grade CNC 3-axis milling machines like the 2-420 from Stepcraft, you can save lots of time and effort after the drawing stage. Depending on the size of your brackets, you can select the proper double or single flute milling bit and produce the parts with great accuracy. The trick is to figure out the speeds and feeds that work best with your material. As a stating point for this brass cutting job I used a feed speed of about 10mm (3/8 in.) per second with a 0.010 in. depth of cut. I ran a 2 mm dual flute up cut bit at about 18,000 rpm. This worked fairly good but I increased rpm to about 2,000. Another good thing about using CAD and CNC is that if you need to make adjustments to your drawing designs and multiple parts, it is very easy. The old fashioned way is very laborious and time consuming. Above is the final version of the lower attachment bracket for my Nieuport 24’s V-struts. Here you can see the final parts cut from the mother sheet of brass material. To keep the parts from flying away after the final cut is made, I use V-Carve Pro to make the G-code that runs my Spetcraft CNC. In the process, I add small thin holding tabs placed around the finished part. When the cutting is complete, I used a fine pair of wire cutters to snip the tabs away, similar to how you would remove molded parts from a plastic airplane kit from its molding trees. Here you see the finished bracket soldered to an alignment pin made from a length of music wire. The bracket has been bolted in place on the lower wing of the airplane. The end of the V-strut (made from 1/4 inch poplar), has been drilled to accept the alignment pin. Once everything has been aligned and measured, the pin is epoxied into place in the strut.

    Snoopy Flies Again!

    Watch out Red Baron!!! That’s right, Model Airplane News has redrawn the classic plans for Al Signorino’s 1969 RC Snoopy’s Doghouse and we’ve cleaned them up with CAD. The old original plans were falling apart and so it was time for an upgrade! If you are a Snoopy fan, watch out for the new 50th Anniversary Special Edition plans in an upcoming issue of MAN. For those who know Snoopy’s Flying Doghouse, this is the improved version that was published in 1971 with the extended fuselage box added to re-balance the model so Al could remove some 2 pounds of lead from the model! We’ve very excited! The post Snoopy Flies Again! appeared first on Model Airplane News. View the full article

  5. When it comes to giant scale warbird excitement, nothing can beat high speed passes by P-51D Mustangs. And when you have two Mustangs burning up the skies in formation, then you really have a show! These two 20% scale P-51s put on an amazing display at the annual Willis Warbirds Flighter meet in the UK. “Trusty Rusty” piloted by Richard Scarbourough along with his buddy Nigel Scarbrock make it look so easy. Trusty Rusty was scratch built from Ziroli plans and is powered by a 3W 62cc gas engine. Richard’s model comes in at about 32 pounds and is flown with JR radio gear. Believe it or not, Nigel built, painted and setup his “Punkie II” in only four months starting with a 20% scale CARF-Models kit. Powered by a 3W 76cc gas engine, his Mustang has a 102 inch span and weighs 37 pounds. It includes Sierra retracts, Savox servos and is controlled with a JR 28X transmitter. The beautiful P-51 is painted with a base coat and then with lacquer. The post Amazing Dual Mustang Flight — Fighter formation at its best! appeared first on Model Airplane News.

  7. Everyone who knows giant scale RC, recognizes the name Ziroli and the father and son team of Nick Sr., and Jr. Nick the elder is known for being the father of giant scale Warbirds and Nick Jr., continues to be a driving force in the RC industry. Nick Jr., took over “Ziroli Giant Scale Plans” when his father retired and turned it into a very popular online web company serving the needs of modelers who have (or want to buy) Ziroli plans. Nick also has a large line of RC hardware and products including many molded fiberglass accessories for the warbirds built from Ziroli Plans. Also running his own full-size industrial vacuum-forming company, Nick has been able to enjoy piloting full-size aircraft and warbirds. It is common to see Nick fly his Full-size Stearman PT-17 Navy (N2S-3) and his company plane a Beech Baron twin. You never know where Nick is going to show up! (Above) A shot out of the Miss Hap’s cockpit flying back to Long Island from Maine. When it comes to serious warbirds, Nick has continued in the area of full-scale warbirds with the same passion that has made his company such a success. Associated with the American Airpower Museum in Farmingdale, NY, Nick regulary flies the museum’s B-25 Mitchell medium bomber “Miss Hap”. The museum takes the B-25 to airshows and it goes to NJ for scheduled maintanence. Since it requires a 2-man crew and Nick already had a multi engine rating, things works out pretty good. (Above) Business end of the Miss Hap B-25 Mitchell (Above) Lots of horsepower available with two of these running! (Above) Miss Hap at the 2010 Dolittle Raider Reunion fly in at the Grimes Field in Urbana, OH. Nick also is checked out and qualified to fly one of the museum’s North American AT-6 Texans, as well as the enormous Grumman TBM Avenger, and the Douglas C-47 cargo plane affectionately called the Gooney Bird. (Above) Nick as Pilot-in-Command of his first Stearman PT-17. Nick flying his newest Stearman. Nick says that the Grumman TNM Avenger flies like a truck! Flying the AT-6 Texan is a lot of fun and keeps you on your toes during landings. He give rides during the museum’s open houses and airschows. Nick’s newest ride is the impressive Curtiss P-40 Warhawk. It flies as great as it looks! When it comes to knowing how to fly warbirds, both RC and full-size, Nick’s log book is an impressive read for sure! The post Nick Ziroli Jr. — Warbird Pilot! appeared first on Model Airplane News.

  8. Because it’s used in so many other maneuvers, it’s important to perfect this one and add it to your foundation repertoire. High-speed rolls are generally easier to start with because inertia is a tremendous help. Long, graceful rolls are usually done at medium to high speed to allow inertia to help keep the maneuver axial. Keep the midsection of the roll (when the plane is directly inverted) centered on your position. STEPS TO SUCCESS 1. Begin the maneuver by flying straight and level either into the wind or downwind and then initiate the roll with a little aileron (constantly maintain that throughout the maneuver). 2. As the roll begins, apply rudder to maintain a straight and level heading. (If the roll is to the right, use left rudder and vice-versa.) The maximum amount of rudder will be required when the wing reaches vertical. 3. As the plane continues to roll past vertical, start to ease off on the rudder and begin to apply down-elevator until the plane is inverted. At this point, you should have applied the maximum down-elevator needed to maintain level flight. 4. As the roll continues, begin to ease off elevator and apply the appropriate rudder (at this point, right rudder for a roll to the right) to maintain altitude as the plane rolls around again to vertical. When the wing is in the second vertical position, the plane should again have the maximum amount of rudder, with no elevator input necessary to maintain level flight. 5. The plane will continue to roll over until it is in the upright position. During this time, slowly release the rudder stick so that there is no rudder input when the plane reaches its upright position. Exit at the same altitude at which you started the maneuver. PRO TIPS Problems can occur if you push too much down-elevator as the plane is inverted. Another frequent error is pushing the elevator stick too soon, while the plane is right-side up, or not releasing the elevator quickly enough as the plane rolls back over.

  9. I put a huge amount of detail in the helmets of my Best Pilots pilot figures because its the topmost thing that’s viewed when your pilot is sitting in the cockpit. Most flight helmets are leather and that’s what’s shown here. The following technique works like magic in replicating leather of all kinds, but it works the best when your pilot figure has leather texture molded in the helmet. I’ve included information here for doing a bang up job on WW2 Navy cloth flight helmets as well. Text & Photos by Lyle Vasser First paint the helmet, earphones and goggle frames flat black. When painting areas like this, it is quicker to paint where the black meets another color with a fine brush and then fill in with a larger brush. Kind of like coloring within the lines in a coloring book. After all is painted flat black and dry we are going to learn a technique called dry brushing. Dry Brushing is a fairly easy technique to highlight raised detail. A medium soft flat brush works perfectly. Mine is all curled out at the ends from use, which actually makes it work better. The trick is to not let a lot of paint come off the brush. To help this, just barely dip the tip of your brush into the paint. You only want about a 1/16 of an inch of paint on brush. In this instance, the color we are going to paint Sailor’s leather helmet is, uh, MMA Leather. After dipping your brush ever so slightly into the leather paint, brush it on an old clean T-shirt until there is almost no paint coming off the brush. (If you have visitors in your painting area, be sure to use an old T-shirt and not underwear… for obvious reasons.) Lightly whisk the brush across the area to be leather. Magic starts to happen and the black helmet starts to look just like leather. For a darker leather helmet, use less paint and for a more brown leather helmet use more. This technique takes the most time, but it is the most rewarding for the realistic effect achieved. Navy Helmets The Best Pilots Pappy Boyington figure uses an altogether different technique since WW2 Navy/Marine flying helmets were made of cloth not leather. But we do use the Dry Brush technique to get the earcups to look like leather that house the headphones. To get Pappy’s helmet to look real, first paint the cloth area MMA Dark Tan. To bring out the detail, we apply a wash. -Washes- A wash is simply thinned down paint that is very watery. This allows the pigment to run into lower areas like stitches, ridges and seams to make that detail “pop”. I discovered a very useful wash that works a bit better than plain water. We’ll call it Best Pilot’s Wash. To make, mix slowly- no bubbles – 5 parts water and 1 part Future floor polish in an empty medicine bottle or similar container. The Future is a well-used magical liquid used by fine scale modelers for years, and they are still discovering new uses for this liquid in modeling. Check it out online. The stuff is pure acrylic so it mixes great with MMA Acyrlic paint. When used in Best Pilot’s Wash, it tends to let the paint pigment settle into the crevices better and not creep back out like it would if using plain water. That’s my theory anyway. Only drawback, if there is one, is it leaves a shiny surface which will be corrected later with the flat clear coat. Take a drop or two of Best Pilot’s Wash and add just a tiny drop of burnt umber so that you get a light brown transparent puddle. Take that and wash it over Pappy’s helmet, taking care to make sure it flows in all seams and NOT over the face or skin areas. You gotta be careful with that. I’ve noticed that the pilots in the South Pacific had prominent sweat stains around the goggles on their helmets. Something to do with flying and fighting in a tropical environment tends to make one sweat! To achieve this effect, simply wash a layer of burnt umber and Best Pilots Wash in those areas. Usually about three layers will get the effect. MASTER TIP- Dry Brushing brings out raised areas of detail and mimics highlighting and fading. Washes brings out recessed areas of details and mimics shadows. Drybrush = light, Washes = Shadow To finish the helmet, you can lightly dry brush a bit of light tan on the seams and straps that hold the goggles on. This makes those details stand out realistically and adds to a more complex color variation. Goggles Straps – The goggle straps on Sailor were a bit more complex than his American ally’s. They were part cloth covered elastic and leather. For the cloth part I painted it with MMA Dark Tan and then applied a very thin Best Pilot’s wash with a bit of Burnt Umber. The leather part of the strap is painted MMA Flat Black and then dry brushed with MMA Leather mixed with a bit of Burnt Sienna for an almost wine color. This gives a nice variation in leathers and is historically accurate. Pappy’s goggle straps are a base of MMA Flat White with a very then Best Pilot’s wash with a bit of Dark Grey. The goggle frames are painted with a base coat of Flat Black (don’t paint the lens area yet!) and dry brushed with the same wine-ish color brown. Pappy’s goggle frames are MMA Neutral Grey dry brushed with MMA Flat Whit HEADPHONES The headphones are left black. For extra detail, dry brush them lightly with a touch of grey, just the upper area and seams. There are two screws on the headphones, to give them a bit of a metallic look, I touched them with a metallic silver colored pencil. Use metalic enamel paint for other metal parts for a “metalic” look. Add the “Best Pilots” printed lenses and the job is complete! Pretty good eh”? (Above) Whether in a Corsair, or in a Wildcat like our lead photo, (both taken at Top Gun!), Pappy Boyington from Best Pilots looks like the real MacCoy! Lyle’s painting techniques and his sculpting talents are simply, well… the BEST. The post Scale RC Pilot Figure Painting — Add life to your fighter driver appeared first on Model Airplane News.

  12. When it comes to building scale model airplanes, one task often stops new projects from even getting started: making a scale engine cowl from scratch. To produce a fiberglass unit, you have to build a master plug, lay up a female mold on top of it, and then use the mold to lay up the final cowl with fiberglass cloth and resin. Here’s how I made a “one-off” cowl, and the technique and materials needed can be used for any scale model you want to build.

    Giant Scale Me 262 Swallow

    When it comes to giant scale RC aircraft, nothing even comes close to amazing and gigantic aircraft that Ali Machinchy pilots. Here’s a video of Ali’s 1/3-scale Messerschmitt Me 262 powered by twin turbine engines as it performs at the Classic Jets Meet at the RAF Abingdon base In Oxfordshire. With a span of 181 inches the Me 262 weighs in at 100 lbs. Powered by twin 50 lbs thrust turbines, this amazing WW II Luftwaffe jet fighter was a one off design that was scratch built by John Greenfield in the UK. Ali purchased it and had it re finished, then went on to Fly it for a number of years before he sold it to a collector in the US. As can be seen, the Me 262 has no lack of power and with several video cameras onboard, this video make you feel like you in the air along side the sleek jet fighter.

    Glow Plugs Explained

    With the ever popular use of electric power systems, glow engines have started to before less understood by newcomers to the hobby. Once the mainstay of the hobby, 2-stroke glow engines still have a lot to offer and produce excellent power for their weight. Once you’ve decided to give a glow powered airplane a try, ask for help and always break in your engine before your first flight. Here are three of the most asked question about glow power. WHY DOES THE GLOW PLUG CONTINUE TO WORK AFTER PULLING OFF THE STARTER BATTERY? When hooked up to a battery, the glow plug’s coiled-wire element glows bright orange, which creates a temperature in excess of 1,500 degrees F. Once the engine is flipped over, either by hand or a starter, the compressed fuel/air mixture will ignite. If the mixture is right, the engine will become self-sustaining so that when the battery is disconnected, the engine continues to run. Simply put, what happens inside the combustion chamber is that the coiled-wires are heated up from the compression stroke and continue to glow for the next compression stroke, igniting the fuel/air mixture, which in turn, heats up the wire for the next cycle. HOW DOES AN IDLE BAR HELP THE IDLE? The idle bar is there to keep the glow plug from getting extinguished when the engine is throttled up. When the engine is idling, it has a tendency to pool up some fuel in the crankcase so when the engine is throttled up, that puddle is forced through the cylinder transfer ports. These ports direct the flow right at the glow plug. With an unshielded glow plug, that fuel hits the wire element and instantly smothers it. The idle bar in front of that wire element helps prevent the flow of fuel from hitting the wire and thereby keeps the glow plug lit. If you have a problem with the engine choking out when you go to wide open throttle, you may want to try a glow plug with an idle bar. WHY ARE THERE DIFFERENT GLOW PLUG TEMPERATURE RATINGS? We have different plug temperature ratings so they can be used to change the performance of the engine depending on the flying conditions. Because our engines have a fixed compression stroke and operating setup, the perfect ignition point will change with different running conditions. Some of these can include compression ratio, nitro or oil contents in the fuel, weather conditions and propeller load. By using plugs with different temperature ratings, we can adjust the ignition point so it’s not too early or too late. Once you find that sweet spot, your engine will produce the best performance.
