  1. RC Prop Balancing Made Easy I have been often asked, “Do I need to balance my prop?” and the quick answer is always “Yes!” A properly balanced prop will give you more rpm from gas, glow and electric engines. A balanced prop will reduce the wear and tear on your aircraft by greatly reducing vibration, which leads to reducing premature failure to all the components and thereby giving your aircraft a longer life. You need to do it on every prop, every single one. There are several types of balancers on the market today that will do a great job of getting different size props balanced. No matter which you use, the balancing procedure will be the same for all. 1: HOLE SIZING The first step is to enlarge the shaft hole to a size that fits your engine. If you balance the prop first, then enlarge the hole, you will have to come back and balance the prop again, so save some time by balancing afterward. The best way to do this is by using a good prop hand reamer because this will keep the hole concentric. 2: FINDING THE HEAVY BLADE The second step is to place the prop on the balancer in the horizontal position to find out which side has the heavy blade. 3: REMOVING MATERIAL Two m*thods are commonly used to balance the propeller. The first involves lightening the heavy blade until the propeller balances close to the horizontal position. Use a razor blade or sand paper to remove small amounts of material while rechecking the balance. Don’t forget to wipe off any dust or shavings before re-checking the balance. 4: ADDING MATERIAL The second requires adding material, generally clear spray paint or thin CA glue with a little kicker to the lighter side of the blade until it balances in the horizontal position. You want to use a fast drying paint and wait until it is dry, because it will be a little lighter when dry. To speed up this drying process I use a blow dryer. Both ways will work well; I generally will remove material from fiberglass/nylon and carbon fiber blades, while using the addition m*thod to the wood blades. 5: PRELIMINARY BALANCE Once the heavy blade is identified and the prop balanced level or within five to 10 degrees in the horizontal plane you can move to the next step. 6: HUB BALANCING Place the heavy blade down so the prop is sitting in a vertical position. Check to see which way the prop wants to drop towards horizontal, whichever way it drops, you will need to add some thick CA and kicker to the opposite side so that the prop can balance in the vertical position. 7: FINAL BALANCE Now move the prop to any position and see if it stays there, if it does then you have a balanced prop. If not keep adjust the amount of CA on the hub by adding or sanding off (in case you over did it) until it does. You may also have to adjust the blade weight to fine-tune the balance. 8: MARKING THE BALANCED PROP After the prop is balanced, put some type of mark on it so you know it is ready for flight. I use a felt-tip marker to write a “B” on the hub for balance. The post Stop the Vibration! appeared first on Model Airplane News. View the full article

  3. East Coast and West Coast VQ B-24 Pilots meet at Bomber Field in Monaville Texas for the 31st Annual B-17 Gathering & Big Bird Fly In! Mark Glanville of California and Mike Bost of NC flew several sorties together with their VQ Warbirds 110-inch B-24 Liberators and they looked amazing in flight. (Above) Mark Glanville added custom 90th Bomber Group Jolly Roger markings to his VQ B-24 as a tribute to his uncle, Paul Glanville, his crew and all the men of the 90th BG. At 25 years old, Captain Paul Glanville was in the 5th AF, 90th Bomb group, 320th Squadron. He flew B-24 Liberators in the Pacific Theater of WWII with his brave crew and has told Mark that Old Iron Sides was his favorite B-24 to fly. Smooth flying, easy on the controls and reliable. Mark says his VQ B-24 Model flies smooth and is easy on the controls just like the full scale! (Above) Mike Bost loves the Jolly Rogers and marked his up as “The Jolly Roger” and custom made his own vinyl graphics!

  4. One of the things we like best about MAN readers is that they’re sticklers for accuracy: if we publish a photo of a plane that has incorrect markings, the letters pour in! A few years back, a reviewer followed the box art and placed the stars and bars insignia upside-down and reversed the upper and lower wing markings, and the poor guy is still hearing about his “crime”. Lately, it seems ARFs often come with inaccurate insignia already attached, and that’s a shame–especially when it’s a nice-looking scale plane. And what about insignia, such as the sw*stika, that is deeply offensive to many people? In Germany, displaying a model WW II plane with a sw*stika would get you on the fast track to being fined or even arrested. We’ve wrestled with the question about swastikas on planes in the magazine, trying to balance sensitivity with scale fidelity. Only once have we removed a sw*stika from a printed image, and that was on a sport-scale model that had a swastikas incorrectly placed — on its upper wing, if memory serves. We have even published a cover with a plane that had a sw*stika on its tail, understanding that while it might offend some, it was a beautifully detailed scale model of a WW II fighter that deserved its place in history. So we ask, when do you think it’s OK to remove a scale marking from a plane like the Stuka dive bombers pictured here? We’d like to hear your thoughts.

  5. For many years, Model Airplane News used amazing artwork produced by Jo Katula on the magazine’s covers. Katula was a historical aviation expert as well as a draftsman and a very talented artist using various mediums. One of our most popular was a Douglas SBD Dive Bomber, that Jo painted using a famous wartime photograph taken in the South Pacific during WW II. The cover was used on the October 1959 issue of MAN. Here’s some photos of the artwork, cover and photograph. The black and white photo comes from the Air Age Media Archives, but there are several copies of the same photograph on the internet. We still have the original artwork produced for the October 1959 issue of Model Airplane News cover. The post Historical Artwork Cover appeared first on Model Airplane News. View the full article
  6. This past weekend, editor Gerry Yarrish flew backseat in Nick Ziroli Jr.’s beautiful AT-6 Texan during formation flight training. Based at the American Airpower Museum at the Republic Airport in Farmingdale, the flight was flown over the Long Island Sound. Nick flew with Craig Sampson during the training. Nick Gets Gerry all tucked into the backseat. There is a certain way you get into a Texan, and it takes some time. Nick puts on his flotation ring . Since the flight would be over Long Island Sound, this is a requirement for both pilot and passenger. Nick gets ready to crank up the engine! Controls and Mag checks OK, and both Texans are ready to go! The half hour flight included station keeping, and close in tight formations and maneuvers like 360 degree and 180 degree turns, tight 45 degree bank turns, as well as Lazy Eights and hard breakaways. Forward view from the back seat. Gerry says, even thought it was a glorious day and there wasn’t a cloud in sight, at the end of the flight, he was “well rung out”! Though the maneuvers were not overly aggressive, the higher than normal Gs had Gerry ready to land and start bragging about his experience.

  7. Here’s a fun way to end the work week! We found several great RC airplane crash videos from a fun loving club who’s not afraid to show the darker side of our hobby. We all know watching airplanes losing the aerodynamic argument with gravity is painful, unless of course it’s someone else’s airplane doing the ground penetr*tion t*sting. Watch this light-hearted video and see if you agree with us, that the guy trying to fly his Mustang in the corn field has a lot of the Right Stuff! Thanks go to The Mayday Flyers for posting this and several other painfully fun RC videos. Enjoy! The post Friday Fractured Flyers! appeared first on Model Airplane News. View the full article

  10. Model Airplane News has devoted many articles and columns to the improving of static scores in scale compet*tion. This score however, only represents 50 percent of your total, and taking the time to improve your model’s doc*mentation material between events can definitely help you maximize overall score. But for this article, let’s talk about improving your flight scores and how to help both the pilot and the flight judges do their jobs correctly. When you fly your model at a scale event, you will be faced with variable conditions, including: • Wind direction. Wind has the biggest effect on models because it can change quickly during the day. It affects takeoff direction and the headings of the maneuvers flown. Plus, it is usually calmer in early morning and windier during midday. • Position of the sun. The sun’s position often requires you to move your maneuver to the right or left of the flight judges; this is done for safety and is OK with them. But moving your maneuver can throw you off pace a bit and make you a bit uncomfortable. • Flightline position. If you have to come in over a tree line to land, you may tend to fly the approach higher than normal. If your flight station is also close to the trees, your landings may be slightly past the judges’ centerline. Don’t expect perfect flightline placement. • Field conditions. The runway can be grass or paved; either surface will greatly affect your model’s ground handling. The length of your takeoff will also be affected by the grass’s length, while paved surfaces are a nightmare for airplanes with non-steerable tailskids. • Time of day. It might sound silly, but the time of day also has an effect on your flying. Early-morning flights are affected by the dew on the grass; it makes landings slippery. In the afternoon, heat rising off the pavement can cause turbulence. As the day goes on, crosswinds can replace calm conditions. PRACTICE To improve your ability to deal with changing conditions, you have to practice. If your club’s field has a grass runway, practice flying from it both when the grass is newly mown and when it’s overdue for a trim. Fly early in the morning and late in the afternoon; practice landings and takeoffs from both the left and the right. Fly on windy days, and when it’s calm. Experience will help you become a better competitor, and being prepared for change often means the difference between an average flight score and a good one. AVOID CONFUSION Preparation is a good thing for contestants, but I think it’s equally good for judges. They should be prepared to make allowances for field conditions, weather and unforeseen events. Most important, everyone needs to understand what the various flight maneuvers are supposed to look like and how they should be performed. I think it will be to everyone’s benefit if all participants (judges and pilots) refer to the AMA rules in the most recent Compet*tion Regulations booklet. These guidelines separate maneuvers into three categories that are judged: Precision, Presentation and Realism. For the sake of consistency, give each category some thought (whether flying or judging them). Let’s take a closer look at these important areas to be judged. • Precision. A contestant should always talk to the judges before beginning to fly and explain what each maneuver will consist of so the judges can form a mental image of the maneuver. Whatever you say you’ll be doing is what the judges will look for, so be certain to do what you said you would do! If you say that your Ju-87 Stuka dive-bomber will perform a 90-degree bombing dive before it releases its bomb, don’t dive the model at a 75-degree angle. Judging begins when the contestant announces “Beginning now!”, and it continues until he calls, “Maneuver complete!” After announcing the beginning of the maneuver, fly a straight course for about 50 feet before actually performing the maneuver. Do this at the end as well; fly 50 feet along a straight path before calling the maneuver complete. If done in a smooth, prototypical manner, course corrections are downgraded, but not severely. Most maneuvers should start and finish at the same altitude (exceptions to this are the split-S, 360- degree descending turn, 3-turn spin and the Immelmann turn). Keep your wings level, and don’t make abrupt altitude or heading changes during your maneuver. To maximize your precision score, you want to perform centered and balanced maneuvers. You can’t give the flight judges too much information before your flight. Don’t just say you’re going to execute a roll—be specific! Will it be a barrel roll or an axial roll? What should the judges look for? If you tell them, your score will be higher. • Presentation. I love this part because it is so basic. For a maximum score, present your maneuvers so they can be judged easily. The best place to perform a maneuver so the judges have the best view of it depends on which maneuver you’re performing. For a clear view, a stall turn or a wing-over should be offset to the left or right of the judges. Maneuvers that have horizontal symmetry, such as loops and cobra rolls, should be positioned with their midpoints centered in front of the judges. It is also important to fly above the runway’s centerline or at the proper distance from the judges, as stated by the contest director (CD). This is an important safety issue, so pay attention at the pilots’ meeting. If you move your maneuver to the left or the right of the judges because of the sun’s position, be sure to explain what you are doing. If you fly through the sun, you can receive a severe downgrade. Your presentation will also be affected by the aircraft you fly. A fast-moving jet or WW II fighter is best presented at a bit of a distance from the judges. Slower WW I or civilian aircraft benefit from being flown closer. • Realism. It is difficult to explain how realism is scored because it is so subjective. To maximize your score, fly only those maneuvers that your aircraft was capable of doing in full scale. Hotshot pilots who perform three axial rolls with a model B-29 should expect a downgrade. For better realism, stick with prototypical maneuvers. The size of the maneuver should also reflect the aircraft’s capabilities. A jet could make very large loops at high speed, but performing small, tight loops would result in a downgrade because in the full-size plane, the pilot would have been subjected to high-G forces. A J-3 Piper Cub would be capable of making loops, but because of the Cub’s limited power, the loops would have to be somewhat small in diameter and more oval than perfectly round. A pilot who performed high-speed loops with this type of plane would be significantly downgraded. Aircraft size may also affect a pilot’s Realism score. A 1/4-scale Sopwith Pup is expected to perform larger maneuvers than a 1/8-scale Pup. It is very important to account for the scale size and speed of your plane. Smooth, graceful flight presentations have a great impact on realism. Judges often pretend to be passengers in the aircraft they are judging. j*rky, b*mpy flying is unrealistic and will hurt your flight score. Abrupt takeoffs and landings also cause downgrades. COMPILATION Placement, Presentation and Realism make up equal parts of the flight-scoring process. At some events, Realism is treated as a separate flight maneuver worth 10 points, and it is evaluated during and between each maneuver you fly. These 10 points are more of an overall grade of how realistically you performed with your aircraft. In general, flight judging is more difficult than static judging because it relates to how we think the prototype aircraft flew. When your model is static-judged, it is compared to your doc*mentation booklet and your 3-view drawing. If you talk to the flight judges beforehand and tell them what your maneuvers will look like, it will help them to score you more consistently. Are there other factors that affect flight scores? Yes; the basics—being polite, being org*nized and being ready to fly when you’re called to the ready box—will undoubtedly help. Improving your flight score is an ongoing process. THE JUDGES’ POINT OF VIEW Let’s face it. Flying in compet*tion isn’t easy. The AMA rulebook covers scoring downgrades quite specifically, but when it comes to Presentation, I feel that the judges should focus on maneuver position using three references: looking upward, looking to the sides and looking straight ahead. I prefer to work with 1/4-point deductions because they are fairer to pilots who fly many different types of airplanes. Figure 1 shows how two judges sitting together can have varying perspectives when viewing a maneuver that’s being performed right in front of them. Each judge should be aware that a maneuver that appears to be to his right or left may actually be placed correctly in the center. I don’t think this “middle ground” should have any downgrades applied for placement, and each outer area should use an ascending Vi-point deduction. Figure 2 shows a side view that uses a 45-degree angle to establish its upper boundary. Downgrades are given for flying above it or for flying too close to the judges. Again, there are no downgrades for flying below the 45-degree angle. If a pilot performs a stall turn, a spin, or a specific high maneuver, and the highest part of his maneuver is above the 45-degree angle, his score is not downgraded. Figure 3 shows what the judges see when they look straight at the flying field from their seats. Each maneuver requires its own interpretation for the “ideal flying zone,” but once that has been done, all downgrades should follow the same standard. By using Viewpoint downgrades, a judge can determine if the maneuver is positioned too far off center, too high, too low, too far away from the flightline, or if it is too large. If we keep in mind that the pilot must still perform his maneuver with regard to perfection and realism, I think the 1/4-point deduction system is a fair way to score.

  11. We at Flight Journal consider it to be an honor to present stories of those who were directly involved in the events of 9/11 as pilots or flight crew. This is yet another view of the event that has shaped our present and our future. “Our plane has been hij*cked. Flight attendant #1 stabbed. Flight attendant #5 stabbed. A business class passenger’s throat has been slashed and he is bleeding severely and may be dead. The captain is not flying the aircraft. Som*thing’s terribly wrong. I see the water. I see the buildings.” After a short pause, she says, “We are flying low. We are flying very, very low. We are flying way too low! Oh my g*d!” The phone went dead. “A colleague relayed this information to us on a conference call at approximately 10:30 a.m. central time at American Airlines headquarters in Fort Worth. One of the flight attendants aboard hij*cked American Airlines Flight 11 was able to connect with a manager at her base in Boston and relayed crucial information shortly before the aircraft crashed into the World Trade Center. “Earlier, I was driving into work on a gorgeous Tuesday morning. The DJ of my favorite radio station said it was the 11th day of September and just in from the newsroom was a report that a small general aviation aircraft had hit one of the World Trade Center towers. I thought to myself, ‘How horrible’ and figured that someone flying solo had probably had a heart attack at the yoke or som*thing.

  12. Built from the 1/3-scale Balsa USA kit, Mike Gross Sr.’s aircraft has a ready to fly weight of 46 pounds, including the 3 pounds of lead ballast added to the firewall. Its 3W-85xi-CS engine, equipped with a 3W header pipe and canister m*ffler system, easily turns a Xoar 28×8 propeller. Mike’s radio is a Gen 2 Spektrum DX18 transmitter and receiver with Savox SA1231SG and SC0251MG servos. Mike also has aboard three A123 2500mAh LiFe battery packs and switches from NoBS Batteries. The 9.3-inch vintage wheels are from Du-Bro and the aircraft is equipped with a Sullivan Skywriter smoke pump and a Bad Dog smoke injector. The covering on the wings is 1/3-scale printed four-color Lozenge Linen fabric from Glenn Torrance Models, while the fuselage is covered with 2.7 oz./yd. unbleached and softened linen. All of the linen has two coats of nitrate dope followed by six coats of butyrate dope. Mike finished all of the painted surfaces with Klass-Kote epoxy paint, and he drew the lettering and markings with Red 5 Designs paint masks. Mike created the weathering with stains and acrylics, all of which he protected with a final finish of two coats of Min-Wax oil-based polyurethane. The Fokker’s scale paint scheme is that of pilot Lt. Alois Heldmann’s aircraft in the spring and summer of 1918. The fuselage bottom and axle fairing are pale blue with the standard factory applied fuselage streaky green, with a yellow nose and checkered top and bottom stabilizer and elevators. Also of interest is that in July and August of 1918, Lothar von Richthofen (the Red Baron’s brother) flew several sorties with this aircraft.

  14. Expecting the return of the club’s winter membership and the area’s winter guests, the Casa Grande RC Flyers club is preparing for this coming season. Also, to facilitate the hundreds of visitors who attend the club’s many events, the city of Casa Grande installed informational directional signs at the intersections of Trekell and Arica roads and Arica and Isom roads to assist attendees and new members in finding the club’s airfield. The club just finished selecting a fifth charitable org*nization to help: the Pets In Need Action League, which assists pet owners who are unable to afford food and medical care for their pets. Not only will that charity ask for donations at one of the club’s events, it will also provide doughnuts and coffee to members and visitors at some of the club’s major gatherings. The Pets In Need Action League will be joined by the Casa Grande Food Bank, the Valley Humane Society, the Hosp*ce Charitable Fund, and the Boys & Girls Clubs of Casa Grande, all of which benefit from the club’s activities. A couple of the major events this next season include the Fly-In for Hosp*ce on January 11, 2020, and the club’s seventh annual air show on March 14, 2020. A full list of the club’s major events, as well as directions to the club’s airfield, are listed on its website: www.CasaGrandeRCFlyers.com. The Casa Grande RC Flyers is an Academy of Model Aeronautics (AMA) Gold Level Leader Club. It is also an Arizona nonprofit dedicated to promoting interest in model aeronautics and giving back to its wonderful community, which has supported it throughout the past seven years. The org*nization provides free flying lessons and holds principals of aviation classes at area schools and clubs. View the full article

  20. Sooner or later you may want to try your hand at flying a scale subject. Since most full-size aircraft use fl*ps, many scale model also require them for true scale operations and function. A scale model with fl*ps fully deployed is a cool sight. If you have never flow a model with then there are a few things to know about. There right ways and wrong ways to use them. This article should help you understand what’s going on. In a nutshell, when fl*ps are lowered they change the wing’s lift and drag characteristics and lower the stall speed. By changing the camber of the wing, the lift and drag are increased for a given airspeed. As a result of these changes affect the speed that the aircraft can land. Common fl*ps Though there are four basic types of fl*ps: plain split, Fowler and slotted. The plain flap is the most common and is simply a hinged portion of the trailing edge. It is usually hinged at the top of the control surface since it only moves in a downward direction. Super Cubs, Cessnas and other sport scale models use common fl*ps, to keep construction and function simple. If you have never flown with fl*ps before, don’t worry. fl*ps add flexibility to your model’s flight envelope, and it is a fun new experience. The major advantage is they shorten (and steepen) your landing approach by allowing your plane to fly more slowly in a nose down attitude. Here are some hints! Do’s Learn how your plane reacts to fl*ps at a safe altitude before attempting the first landing. Reduce the throttle to around 1/3 and let the plane slow before dropping the fl*ps. If used for takeoff, use only partial fl*ps. Adjust the power to maintain the approach path. fl*ps add drag and so will require more power. Add power on a go-around and begin your climb out before retracting fl*ps. Don’ts Deploy fl*ps at high airspeed. The fl*ps may depart the wings or cause serious structural or servo damage. Use fl*ps on the first takeoff and test flight. You must first determine how much deflection is correct for your model. Use full fl*ps on takeoff. This adds a lot of drag. Let the plane balloon and lose its airspeed. Adjust the elevator to keep the proper approach path. Retract fl*ps when low and slow or you could settle onto the runway. Deploying fl*ps may result in the plane pitching up or pitching down. The elevator must be used to compensate and keep the plane on the desired approach path. Another characteristic of fl*ps is that the first half of the flap’s deflection results in a greater increase in lift while the second half results in a greater increase in drag. fl*ps also impart a large structural load on the plane and should only be used at a lower airspeed. Full-size planes have their air speed indicators marked for safe flap operating range. Flap Facts Since fl*ps provide more lift at slower airspeeds, you must be aware that when you retract them in-flight you will lose the lift and the plane could sink. For this reason, if you must do a go-around, make sure you increase power before retracting the fl*ps. Failure to do so could place your plane very close to stall speed before you can accelerate to a safe speed. This also applies to takeoffs with fl*ps. In most cases it is safer to take off with the fl*ps retracted or deflected no more than about 20 degrees. Larger deflections add more drag and can cause the plane to become airborne at too low of an airspeed. Flying a scale model with operational fl*ps is a very rewarding experience. Not only do they look neat, but they also provide the same benefits as the full-size version. fl*ps impart increased loads on the wing and require attention during their installation. Make sure you use enough heavy-duty hinges on each flap and a heavy-duty control horn. There are many ways to actuate the fl*ps, including torque tubes and bell cranks. For large, fast or heavily-loaded models, the best way is to use a servo for each flap. These planes will also benefit from the fl*ps being locked in the down position preventing the airstream from blowing the flap back to the up position. This basically means that the servo arm is directly in line with the flap horn at full deflection and this takes the strain away from the servo. This is accomplished by turning on the radio and selecting full down fl*ps and choosing a servo horn position that is in line with the horn. Now, retract the fl*ps and make up the linkage from the servo to the horn. The amount of flap deflection is determined by the length of the servo arm; for more flap deflection, place the linkage f*rther out on the arm. The use of ball links may be required for smooth action and to eliminate binding. Flap Deployment The modeler has several options for the transmitter flap actuation m*thod. The least desirable is to use a two-way switch, which only results in fl*ps up or full down. This is not very scale-like and could result in large pitch changes when the fl*ps are actuated. A three-position switch will allow the use of half-fl*ps for more scale-like flight. A kn*b or slider switch is another way to go and allows an infinite number of flap settings. The only drawback is that it is sometimes difficult to tell how much flap deflection is selected. Servo Speed Reducer Another way to minimize the trim changes associated with flap deployment, is to use a slow servo speed. Many programmable radios have the ability for you to slow down the response of specific servos. But most pilots will find that simply adding a Speed Reducer like the one from Dave’s RC Electronics, a quick and simply way to deal with the situation. When the fl*ps take several seconds to lower, it minimizes the abrupt change in lift and gives the plane more time to settle down. Simply plug the unit in between the receiver and the flap servo(s) and you can adjust the speed by adjusting the adjustment p*t on the circuit board. Flying with flap-equipped airplanes is a great experience and just plane fun. fl*ps allow you to operate your model from smaller flying areas and when it comes to scale compet*tion, they allow you to full exploite your subject aircraft’s flight performance while giving you another flight option to add to your flight routine. Give it a try. It’s a blast. The post Flying with fl*ps — What you need to know appeared first on Model Airplane News. View the full article
  21. Editor’s Top 10 Favorite Workshop Tools and RC Accessories While several companies in the RC hobby industry have gone offshore for their production, DU-BRO not only makes quality products designed specifically for modelers, but the company manufactures most of them in their own factory in Wauconda, IL. For over 50 years, the folks at Du-Bro have been creating accessories/tools to make our model airplanes better. Here are our top 10 Du-Bro products 1. Prop Balancing Perhaps the most important thing you can do to maximize your model’s power system, balancing the propeller is mandatory for both engines and electric motors. The DU-Bro True-Spin balancer has a spring loaded mandrel that centers the propeller hub and its precision bearing surfaces provide friction free support. The rest is up to you, but you can’t properly balance a wood or composite propeller without one. 2. Fuel Filters Whether you are running a glow engine or a gasoline burner, to keep your engine happy and running reliably, you need to feed it clean fuel. DU-BRO has been producing the finest fuel filters available and these aluminum inline accessories with last for years and years. Plus you can take them apart and clean or replace the filter screen. Don’t fly without one. You can also double your filtering pleasure by using one between the engine and your model’s fuel tank, and another one in the supply line from your fuel supply container. 3. Fuel Tanks and Tubing and Pumps When it comes to getting your clean filtered fuel to your engine, it is important to use the proper type of fuel line material. And for glow engines, that means quality silicone fuel tubing. Available in short lengths and on the spool, you want the best for your model. And of course, Du-Bro tanks are the gold standard for serious sport and compet*tion modelers. 4. Tubing Bending And while on the topic of fuel systems, the best way to bend the required brass tubing sections is with Du-Bro’s Tubing Bending tool. Designed to make kink free bends, these easy to use tools are a must have for any workbench. 5. Engine Mounts To get the most performance from your engine, you have to install it properly on your model’s firewall. Du-Bro has several to choose from and the shock absorbing type show here, is a great choice for your 4-str*ke engines. Proper mounts will also lengthen the life span of your expensive power plant! 6. Linkage Connectors To maintain fine and positive control of your model, you have to have a solid connection between your servos and your control surfaces. Kwik Grip EZ Connectors are the answer that you can count on. 7. Control Horns Like all of us know, the stronger and more precise your control linkage is, the better your model airplane will respond. For smooth and precise control, you have to have a slop free setup. The best control horns we’ve found are the T-Style Control Horns which are available in different lengths. 8. Hinges Last but not the least important part of any RC control surface are the hinges, and these can be considered the foundation of any model airplanes, control setup. Du-bro’s Nylon Pinned Hinges are available in several sizes to fit standard-size to giant-scale airplanes. 9. Replacement Clevises So, if you are flying ARF models, you can still add to the quality and security of your control linkage with Du-Bro’s new Metric Replacement Clevises. Many overseas ARFs manufacturers try to save money with questionable hardware, and the clevises they use can be weak and ill-fitting. Swap them out with these Du-Bro Clevises and you’ll feel the difference right away. 10. Servos Mount scr*ws After a while those scr*ws that come with your servos can become worn out and difficult to tighten properly. We’ve found that Du-Bro’s socket head servo scr*ws are the best way to keep the servos secured. We replace the stock servo mounting scr*ws on all our aircraft. Quality Made in the USA Hardware Since 1959, the Broberg family has owned and operated DU-BRO Products, Inc. During that time, the company has grown from a single product, to four companies covering three industries, including Radio Control, Archery & Hunting, and Fishing & Marine Accessories. They offer more than 1,200 product items and for their entire business history, innovation and reliability has always been synonymous with the DU-BRO name. Coupling that with great customer service and a knowledgeable, staff, has made DU-BRO world famous brand name. Speaking with the main movers and shakers at DU-BRO, g*yle (Broberg) Lundgren, Kathy (Broberg) Weiland and Jim Broberg commented that: “Our father, Dewey Broberg, created DU-BRO Products with pride, dedication, and customer service. He has passed those values on to us and it is our mission to maintain that level of quality in all we do. Our family history is attached to every product we produce and we do not take that lightly.” “The secret to our success has always been our ability to do almost everything our business needs right in our own facility. We do it all: Injection molding, blow molding, rotational molding, rotational foam molding, scr*w machining, thread rolling, drilling, tapping, tooling, punch press, assembling, vacuum forming, packaging, and much more. We even have our own print shop, in house advertising and marketing, and even television production, right in our own facility. This is how we keep our costs down, and most importantly, how we maintain our very high level of quality control. If we run into a problem, we do not have to wait for a boat to arrive from another country, we walk back into the factory and figure it out and fix it right on the spot. That is the way we have always done things, and that is the way we will continue.” Stop by the Du-Bro Products booth at any trade show and these guys will take good care of you.

  24. Arrows RC has announced a new electric ducted fan 64mm trainer named the Marlin. This is the first electric EDF trainer in its class to be equipped with fl*ps. All parts for the Marlin are stocked in the USA and available through either HobbyZone.com or ArrowsRC.com The price is $159.99. Designed with the beginner to intermediate pilot in mind, this plane has a more rob*st fixed landing gear than most, to handle b*mpy landings. More importantly it is the only plane in its class to have fl*ps to shorten takeoff, and to make approaches and landings more like those of a high wing trainer. The 3150kV motor combined with a 40 Amp speed control, and a powerful 64mm 11-blade EDF, ensure plenty of power for takeoff and maneuvers. The fan sounds like a real turbine. This plane basically has eight scr*ws and some servo connections to complete assembly. No glue is necessary, and because we use 8 servos we are not running a lot of control rods around. Even the nose wheel has it’s own servo. Flap and aileron connections are made with ball linkages, for greater strength at higher speeds. A latch type canopy makes in flight canopy loss a thing of the past. If you are looking for a first EDF to try, or are looking to move up to a EDF without spending a bundle, this plane is for you. Features Sleek aerodynamic airframe scr*w together assembly fl*ps Ball linkages Latch type canopy Ultra durable EPO foam The perfect beginner jet!
