    Yuneec Mantis-Q

    From Yuneec: Your adventure awaits. Mantis is ready. Small yet powerful, Mantis Q features cutting edge, advanced drone features such as voice control and facial detection in an easy-to-use, ultra portable package. Thanks to its energy-efficient design, the drone can stay in the air for a category-leading 33 minutes, allowing pilots plenty of time to record great photos and video clips. When folded together, the Mantis is small enough to tuck in a bag and weighs just 1 pound. It’s the ideal companion for big and small adventures alike. Capture your memories in 4K UHD Using an integrated camera, the Mantis Q records high resolution photos and videos. Still images with a resolution of 4800×2700 (16:9) or 4160×3120 (4:3) pixels are saved in JPEG or DNG format on the included MicroSD card; the same goes for up to 4K of recorded videos. Additionally, the camera can be tilted upwards by up to 20 degrees or downwards by 90 degrees during flight. For cinematic camera flights, the Mantis Q also comes with automatic flight modes such as Journey, Point of Interest and Orbit Me. Vision based tracking and face detection Simply smile at the drone to activate face detection and as soon as the Mantis Q “sees” the user’s face, it will take a photo from up to 13 feet away. In Gesture Control mode, Mantis Q will detect a hand waving and it will take a photo. “Mantis, take a selfie!” With the all new Voice Control feature, users can command Mantis Q just by using their voice. Voice control allows users to take a photo or begin recording video all without having to manually take their hands off of the controls, making it that much easier to capture the perfect shot. Mantis Q responds to commands such as “Wake up” for powering on, “Take a picture”, “Record a video” and “Take a selfie”. Intelligent flight modes Take your creativity to the next level by letting Mantis Q focus on the flying while you focus on the shot. Journey Mode Depending on the desired setting, the Mantis Q will fly upwards on a linear path and then return automatically – making for the perfect shot. Point of Interest Select an object while in POI (Point of Interest) mode and the Yuneec Mantis Q will circle this object automatically. Return Home With a push of a button, the Mantis Q will automatically return to a point near its takeoff area and land by your side. Safe to fly indoors and outdoors Unlike most in its class, Mantis Q comes equipped with advanced indoor stabilization technology. Down-facing dual sonar sensors and infrared detection make it safe enough to fly indoors and outdoors. Added safety features include a “Return to Home” function and FAA-compliant software. Fast-paced fun while flying Users also have the option to fly Mantis Q with and without the added controller. If users want to experience the thrill of drone racing, they can switch to the Mantis Q’s Sport Mode. The Mantis Q can fly up to a maximum speed of 44 miles per hour – and that’s all while performing with the agility of a real racer. The live image can be viewed with a latency of less than (200ms) on a smartphone which is connected to the remote control. Specs: Aircraft TAKEOFF WEIGHT (INCL.

    An RC pilot’s guide to flying off water When most RC modelers decide to try flying off water the question arises, “So which is better: a floatplane or a flying boat?” A floatplane, where the fuselage is sitting up on two floats, is probably easier to control during takeoff, but a flying boat, where the lower section of the fuselage is shaped like a boat’s hull, seems more forgiving when it comes to landing and taxiing in windy or choppy conditions. We just posted this informative article on the Premium website to help explain the basics for those RC pilots who want to get wet!

    Helping our Hobby Grow

    Start a New RC Event If you have ever attended and flown at an RC national or regional event, then you know there’s a lot involved to be successful. Many of our flying buddies, have yet to travel past their local flying field and for many of them, they see our hobby and interest in RC airplanes in general diminish. A great way to help our hobby grow and inject some fresh excitement into any club’s flying field is to start an AMA sanctioned event and then invite RC flyers from other clubs to join in on the fun. Requirements The very first thing I look at is: “will the event will fit in your location”. Meaning, where will everything fit in place? Let’s say we are expecting 60 pilots. Is there room for all 60 to park their vehicles and trailers near where they will pit from? Good. Now, if you are expecting spectators, do you have room for a few hundred cars? Is the parking area solid enough so that if it rains you don’t have a mud-hole? Great. 60 pilots most likely will have a significant other whether that person is their wife, girlfriend, caller or helper. Playing the averages, you can expect at least 65% to have one of these so the base attendance has just increased to about 100 folks. Now, are we gonn’a feed these people? Yes? Great, and how about the spectators? Okay, so do we have a clean spot for a food vendor to set up his operation? Oh, you didn’t think of a food vendor? The Club will take care of it? Great, and they have experience in having 30 or 40 people come all at once at lunchtime for something to eat? If not, then let’s get looking for a food vendor. If we have reached this point, I’ll take it for granted that the event is a GO, so we should apply for the AMA event sanction. Okay, we’ve got a great field to fly from, safe and with plenty of overfly area. We’ve got plenty of space for our pilots and their trailers and some designated area for spectators to park. Are you charging admission? Like $10 a car load or maybe just $5 a person? And you have some club members to stand by the entrance to accept the entrance fee and make change? And of course you figured on a relief crew right? I mean you don’t expect two people to stand there all day do you? Yes, I provide a shade tent for our people at the gate and we do provide chairs for them to sit and rest and we do have an alternate on site to replace someone if they get too hot or just too tired? Oh yes, and because we are charging an admission fee to spectators we also must comply with the Law and provide “Handicap” parking spaces. These spaces must be close to the action so as to shorten the distance from the cars to the viewing area The Basics Well, let’s see, has anybody thought of where to place the porta-potties? That is potties with an S because with a hundred pilots and crew and a few hundred spectators, one pottie just ain’t gonn’a cut it! Just to be safe, let’s get two regular units and one handicap unit. And when we order the toilets, plan on one “clean-out” service, say Saturday morning, to have them all refreshed. Those holding tanks only accommodate about 1 and a half day’s usage. And let’s not forget we’ll need someone designated to keep those units stocked with tissue. Seems we’ve pretty much got it all taken care of now. I mean, if we really wanted to be a class act, we could spring for the $400 to have a “Dining Tent” put up so that patrons and pilots can sit and eat in comfort, out of the sun and dust. Good idea? Great! Flightline Management Heading up to the business end of the site, let’s see what we need to do to make the pilot areas work. Of course we’ll need some sort of tent or structure to house the Registration table. And a PA system would sure be nice so we are able to make announcements. Let’s put someone in charge of setting up the PA system, amplifiers and speakers and check them out beforehand so that we don’t have to fuss with them during the event. Of course a person to handle the announcements, or to keep the spectators informed of what’s flying, would be a cool treat. Don’t forget some sort of large umbrella for that announcer area to keep the guy from frying! Perhaps the next thing to address is something to act as a barrier, and to designate a viewing area, to help protect spectators. We should also think of how we want to protect the pilots from any airplane having a mishap while taking off or landing. PVC pipe makes a great structure with some orange construction fencing tie-wrapped to keep it in place. And while on that subject of keeping pilots safe, are we going to have a “Flight Line Crew” to help announce departures and arrivals, to help avoid any possible collisions? Even two guys would be useful. OH, one more thing! If our site is one that is friendly to belly landings and is wide open enough that we can easily get to downed aircraft, some sort of “Crash Cart” is essential! A Gator or similar vehicle works great. If jets will be in attendance, we really should have some sort of fire-fighting equipment on a trailer towed behind the crash cart to help distinguish any small flames. It’s also a great idea to notify the local Police and Fire Department that you are hosting an event, offering them two contact people’s names and cell phone numbers and the address of the field. Anything Else? Well, I think we’ve about got it! Other than procedural stuff, like whether you allow guys to taxi-back after landing or wish them to clear the runway ASAP, I believe the event is about ready to open for business. Of course we must get some road signs put up in strategic areas to inform the public what and where this show is taking place, and we’ll make sure that the area where the people collect the admission fee is far enough inside the property so not to cause traffic problems with cars stacked up waiting to get in. And we did think of making the entrance road wide enough to allow emergency vehicles to enter or exit while a line of cars is stacked up, right? Great, then as far as I can tell we are all set to rock and roll. Have a great event! SB- First Time Event Check List Discuss details with club members Decide what type of event: Fun Fly, Fly In, Competition, Special Theme. Check for usable dates to avoid conflicts with other nearby events Assign task to AMA qualified Contest Director Contact possible sponsors for awards/prizes/support Send event flyers and invitations to local clubs. (email and USPS) Plan for food, safety and porta-pottie(s) Assign jobs for pilot registration, parking and flightline management Advertise locally and in AMA magazine Make “Thank You” signage to display at event for sponsors After event, publish Club Newsletter to highlight event results and send to local clubs, the AMA and to all Sponsors.

    Award Winning SR-71 Blackbird

    First flown at the 2017 Top Gun Scale Invitational, Top Gun competitor Lance Campbell of Columbia, Missouri, competed with his amazing SR-71 Blackbird spy plane, which scored an impressive 99.167 static points. At the Top Gun awards banquet, Lance also received the Engineering Excellence award, as well as the Critic’s Choice award. Lance returned in 2018 for the 30th anniversary of Top Gun and you could tell Lance has been practicing: he earned the top 1st place position in the Masters Class. He also brought home the Engineering Excellence award. He earned a total flight score of 198.042. Some pretty good recognition for Lance’s 9 year long project. Lance uses a Futaba radio to control his 85-pound SR-71 and it is an impressive 13 feet long. Powered by a pair of JetCat 140-RXi turbines, and he completely scratch built the scale retractable landing gear complete with disc brakes. The amazing spy plane also uses a scale drogue chute to shorten the landing run out after touchdown. Check out this great flight video shot at Paradise Field the home venue for Top Gun. And since a photo is worth a 1000 words, here they are for all of you to enjoy. If you’d like to read more about the background Lance’s amazing 9-tear project, here’s his build log for the plane, that spanned years: http://www.mmrca.org/lance/sledframe.html The post Award Winning SR-71 Blackbird appeared first on Model Airplane News.

  5. Radio control model airplanes rely on two basic systems to fly, the radio system and the power system (excluding gliders). When you have a nitro-burning glow engine if your engine loses its fuel supply, you’ll find yourself in a dead-stick situation with a plane that wasn’t designed to be a glider. To prevent dead-stick landings, the first steps are taken at the workbench while you install the fuel tank and other necessary fuel-system components. Though this is an easy task for experienced builders, newcomers may find it a bit of a challenge. This article will highlight some of the basics of the fuel components that feed your model’s engine and will make all that plumbing more understandable. THE BASICS Fuel tanks come in all shapes and sizes. Fuel filters are worth their weight in gold! Clean fuel means no trash in the tanks. Whenever possible, pad your fuel tank with foam rubber-it helps prevent “foaming.” Just like the family car, the fuel tank contains the engine’s fuel supply. The tank is connected to the engine’s carburetor with flexible fuel line (plastic tubing), and a rubber stopper seals it. For a tank to operate properly, it must have a vent line that allows air to enter the tank as fuel is drawn out. It relieves the vacuum left in the tank. Model airplanes don’t always fly straight and level. To allow the fuel to flow at different attitudes, the tank has a flexible internal pick-up tube. A heavy “clunk” fitting is attached to the end of the pick-up tube to always keep the end of the tube at the lowest part of the tank. If the pick-up tube wasn’t flexible, once the fuel level dropped below the pick-up tube, the supply of fuel would stop and the engine would die. Lengths of brass tube pass through the tank’s rubber stopper, and the fuel lines that carry the fuel to the engine slip over the ends brass tubes. The rest of the fittings and accessories help the fuel system work properly and make it easier to maintain and operate. BAD VIBES Making your fuel tank easy to get to makes maintenance of your fuel system easier to do. The removable fuel tank tray can also secure your battery packs. One common problem that can lead to your engine running lean is fuel foaming in the tank. Vibration causes this and it forms tiny bubbles in the fuel. The bubbles cause erratic fuel flow and the air in the bubbles causes the fuel mixture to lean out. The simple solution to this is to make sure to properly pad your fuel tank with soft foam rubber. Also, make sure that after time, you check the padding to see if any part of the unprotected tank is coming in contact with the model’s inner structure like a former or engine mount bolt or nut. I prefer to use rubber bands to hold the foam padding in place but you can also use tape. Make sure you don’t compress the foam too much as this will lessen its ability to isolate the tank from the vibration. Regular maintenance is key to keeping your entire model in top condition. One way to keep a better eye on your fuel system is to make the tank removable. When there is no fuel tank compartment hatch, I make a slide-in tank tray from lite-ply and a matching set of rails inside the fuselage. This way, I can slide the tank into place and secure it with a couple of small screws. You can save more space by attaching your battery pack to the tray as well. This system works extremely well, especially with large airplanes. To choose the correct size fuel tank for your airplane, check your kit’s directions or check the engine manufacturer’s recommendations. You’ll want a tank that can hold enough fuel for a 15 to 20 minute flight. TWO-LINE SETUP Adding a fuel filter to your fuel supply line gives you double protection. A two-line fuel system is the simplest and almost foolproof way to go. The setup requires only two pieces of brass tube, a clunk, a rubber stopper and a short length of silicone tubing. Bend one tube 90 degrees to form the vent and insert it through the stopper. The vent lets outside air in as the fuel is drained out, and it acts as an overflow indicator when you fill the tank. The second tube is the fuel-supply for the engine and the interior pick-up tube and clunk are attached to it. To fill the tank, the fuel supply tubing is removed from the carburetor and attached to your filler pump line. When the tank is full, you simply reattach the line to your carburetor. The vent line is often attached to a pressure fitting on the engine’s muffler. This arrangement helps pressurize the tank to enhance fuel flow to the engine. 2-line setup The simplest and most trouble-free setup is a two-line tank. THREE-LINE SETUP In a three-line tank, the setup is just like for a two-line arrangement, but a third line is added and used to fill the tank. The third line doesn’t need an interior pick-up line and clunk, but many do add them to allow the removal of fuel at the end of the day. Before running your engine, you must seal off or cap the third line to prevent fuel from leaking out. Fuel line plugs called “Fuel Dots” are available commercially to do this, but you can also use a tight-fitting machine screw or a short piece of ?-inch-diameter brass rod material as well. In a pinch, you can use a one-inch length of ?-inch dowel. 3-LINE SETUP Three-line tank setups allow convenient tank filling without removing the fuel line from the engine. ILLUSTRATIONS BY FX MODELS TROUBLESHOOTING Properly installed, your glow engine fuel system will last a very long time and may never need to be changed. In a hard landing, however, some of its parts may be dislodged or a line can become kinked or pinched. Here are some common fuel-flow problems and fixes. After a hard landing, the flexible pickup tube and clunk inside the fuel tank can be forced all the way forward. This can go unnoticed until the next flight when the tank stops delivering fuel to the engine in a nose-high attitude. To prevent this, solder a short piece of brass tube to your clunk. This decreases the pick-up tube’s flexibility a bit but still allows it to draw fuel in normal flying attitudes. If your engine starts to run lean for no apparent reason, check for small pinholes in the fuel-supply lines. Check closely where ever there is a tight bend or where the fuel or line comes into contact with the firewall. To help prevent chafing at the fire-wall pass-through, drill a small hole in the firewall and use a length of brass tube in the holes. Slip the fuel lines over the brass tubes to complete the system. If your engine begins to run erratically, debris may have gotten into your fuel system. It usually finds its way into the model’s fuel tank from your fuel storage jug, and if it blocks fuel flow, your engine will die. To prevent this, use an in-line fuel filter in the fuel supply line just before the carburetor. Install another filter in your fuel-pump line so you fill your tank with clean filtered glow fuel. Add a combination fuel clunk/filter, and you have a triple defense against dead-sticks. The post Model Airplane Fuel Systems Explained appeared first on Model Airplane News. View the full article

    Fiberglassing Wings Made Easy

    There are many ways to apply fiberglass cloth to a structure. The most common methods use either polyester or epoxy resin and catalysts. Some of the resins require unequal mix ratios, like 1 part epoxy to 2 parts hardener, which is difficult to measure accurately. I also dislike polyester resin because it really smells foul. For all these reasons, I now use Pacer Technology’s Z-Poxy Finishing Resin (#PT40). It is an equal-mix product that has little to no smell and is easy to work with. Cure time to a tacky consistency is about 30 to 45 minutes. After about two hours you can handle it, and after four to five hours, you can sand it or apply another coat. Even if you have never done this before, it is really easy to do. Let’s get started Some items you will need are paper towels, 1-inch hardware-store chip brushes, something stiff to use as a “squeegee” (a credit card works great, as do plastic-coated playing cards), a hobby knife with no. 11 blades, Z-Poxy Finishing Resin, and some denatured alcohol. A flat surface, like an old table or workbench, covered with newsprint or some other disposable covering is excellent for setting parts on. You will also need some 100- and 220-grit sandpaper to smooth out your prep work. A rubber sanding block, available at most hardware stores, will help enormously. Oh yes, and some 5-oz. disposable drinking cups will be useful for mixing the resin. Keep in mind that different-weight fiberglass cloths (from 3/4 to 3 oz.) work differently. The heavier the cloth, the more stubborn it may be to lay down properly—be patient. Whether it is a one-piece or a two-piece wing, pretend that it’s divided into four quadrants: top left, top right, bottom left, and bottom right. It doesn’t make a difference which section you start with. If you have detachable ailerons and flaps, remove them and do them separately. Now, let’s get down to business. Preparation Before you start the first panel, make sure that the whole wing has been finish-sanded with 220-grit sandpaper and then vacuumed clean. Do the other three panels in the same way. If your balsa wing has any dents in it, spray the dented area with a little water and gently rub it into the dent. Let the area dry out; the wood grain will lift slightly, causing the dent to vanish like magic! The general idea here is to have smooth, flat, ding-free surfaces over which to lay your fiberglass cloth. As far as fiberglass cloth goes, my basic guide to what weight to use is directly related to airplane size. For models with wingspans in the 80-inch range, you can use anything from 3/4- to 1 1/2-oz. cloth. Anything 100 inches and over, I use 2- to 3-oz. cloth. You get the idea. To find where to buy your glass cloth, check hobby shops or large distributors. You can also shop around your local boat/marine hardware stores for the cloth you need. Now, measure your wing panels and allow at least an inch of waste material all the way around. After cutting your first piece of cloth, lay it on top of the wing panel and rub your hand over it to make sure that there is nothing under it, as any speck of sanding dust will ruin the finish. The glass act For the first coat of resin, I add about 5 to 10 percent alcohol to the resin. This is not really recommended by the manufacturer because of the variances of alcohol used. But it helps the cloth lie down easier without pulling it out of shape while applying the resin. When you apply the second coat of resin, however, use it full strength. Mix the resin parts together completely, add the alcohol, and mix again until the alcohol is fully integrated. Lay the cloth down over the bare balsa, being sure that it lies down completely smooth. Pour a small line of the mixed resin down the center of the wing panel span-wise, and spread it out from the center to the leading or trailing edge—it doesn’t matter which—then do the rest. Keep a disposable drinking cup handy to squeegee off excess resin from your credit or playing card. Paper towels are nice to have around, too, as well as a 1-inch chip brush to brush down the edges and areas that you missed. Now, spend some time going over those areas; fixing it now makes life a lot easier later on. By this time, your hands will feel as if you just handled a large ball of cotton candy—nice and sticky. Wipe yourself and any tools you wish to keep clean using a paper towel and some alcohol. Trust me—once you have completed the first panel, you will find the other three will go much faster. I usually do the top-left panel followed by the top-right panel and then let cure. I trim the edges with a no. 11 hobby blade and then lightly sand the edges all the way around. I flip the wing panels over and apply cloth to the other side. Don’t build up too much resin near any edges because, when it cures, you will just have more resin to sand off. After you’ve done all four panels and they’re all fully cured, revisit the first panel and very lightly sand and fix any little imperfections or dings that you might have picked up. If you have any wrinkles, bubbles, or brush hairs, now is the time to sand them away. If you must sand down so far through the cloth and resin that it leaves a bare spot, don’t worry. You can cut a small piece of cloth and put it down with the second coat of resin, or if it’s small enough (like the size of a quarter), just ignore it and put down the second coat of resin directly over the bare wood. Go over the other three panels and do the same thing. As for the wingtips, I simply trim close to the wing, apply resin, let cure, and then sand. If needed, I’ll add scrap cloth to cover any bare spots. Once you have all four panels done with two coats of resin and they are fully cured, you can use the sanding block to sand the wing smooth. You will notice that the second coat of resin has cured fairly shiny. This is because it just lies on top and does not absorb at all into the wood or the glass cloth. Use 100-grit sandpaper over the shiny surfaces to “break” the shine, then switch over to a finer-grit sandpaper, like 220, to finish-sand the whole panel. Remember that when you sand the cloth, be careful not to go through to bare wood. The difference now between a good wing surface and an outstanding one is how much time you spend sanding the wing. When you have the entire wing finished as mentioned above, you are just about done. For me, the next part is the final step. Find a well-ventilated area, and get some Rust-Oleum Automotive gray primer (an average rattle can will cover about 4 square feet) and lightly spray the wing panels. The primer will expose any flaws left in your fiberglass surfaces. Fill any pinholes or dings using a lacquer spot putty or Bondo, let dry, and sand and primer again. From here, there are many ways to finish the wing, but that’s another story. For strength, I always glass the wheel-well interiors. Our current project is a giant-scale Grumman Hellcat. As you can see, the wing has been finished nicely with fiberglass cloth and resin and is ready to prime. The fuselage was finished earlier and already wears a coat or two of primer. The same basic technique is done for all control surfaces, as shown here. The parts are set aside until the resin cures, then the excess cloth is trimmed away and sanded smooth using sandpaper.

    Vintage RC Scale Triplane

    MAN editor Gerry Yarrish is what many would call a “Triplane Addict”. He’s built so many Fokker Dr.1s that he can’t even remember them all. From his most recent 1/3-scale giant, to several ARF electric versions and even a few rubber powered free flight Triplanes, Gerry must really love building wings. Here are a few photos of one of Gerry’s favorites, a 48-inch-span version built from the old VK Models kit. This one was powered by a Saito .56 4-stroke glow engine and it was outfitted with JR servos controlled with a JR 8301 radio. The model features an upgraded aluminum engine cowl from Arizona Model Aircrafters and spoked wheels from Proctor Enterprises. The static scale propeller is from Xoar.The covering is Scale Stits and the paint is PolyTone from F&M Enterprises. All of the aircraft markings were masked off and painted. Though the VK Triplane was not the greatest airplane to fly, (actually it was well behaved in the air, but the takeoff and landings were murder!), Gerry did manage to earn a 2nd place award in the WW I class at the 2002 WRAM show, in White Plains, NY.

  9. From HobbyKing: You’ll slice through the sky with this brilliantly colored SkySword. The streamlined looks and elegant lines show that this plane is built for speed. It comes with a 70mm 12-blade EDF fan to provide that realistic jet sound. With the PNF version, all the hard work is done with the powerplant already fitted and ready to go. The tricycle retracting undercarriage and all servos are completely installed with easy connect plugs for installing the wings. All decals have been fitted. Just fit the top of the “T” tail and install a receiver and battery and you will be ready to fly in no time. The three bright LED lights make for easy orientation when coming in for a smooth landing.

  13. From E-flite: E-flite® Radian® motor gliders are legendary because they capture the essence of pure and modern soaring styles in aircraft that are as much fun to sport fly as they are to soar. Inspired and approved by the Flite Test (FT) crew, the Night Radian FT improves the popular 2-meter version with multiple upgrades including a programmable LED light system that allows you to fly all day and night. The horizontal tail is now fully-molded. Plus, the BNF® Basic version features AS3X® technology to deliver smoother flight performance in windy and high lift conditions while optional-use SAFE® Select technology makes this Radian airplane even easier to fly than it already is. The E-flite® Night Radian® FT 2.0m motor glider combines the serenity of soaring with sport flying and incredible night flying capabilities. Factory-installed, high-visibly LED lights are recessed throughout the airframe, including in the redesigned airfoil-shaped horizontal tail. The vivid colors and placement of the LEDs offer incredible visibility and easy orientation when flying at dusk and even in complete darkness—or they can be turned off when flying in daylight. Even more impressive is that the LEDs can be programmed to display 100+ different color, sequence and timing combinations by utilizing the built-in controller. Multiple Night Radians flying together in the dark can be easily distinct. Best of all, even with the addition of lights, the durable, composite reinforced EPO construction has been kept as light as possible so there’s no discernable difference in flight performance or thermal soaring capability. The distinctive and gracefully curved polyhedral wing and efficient airfoil deliver outstanding soaring performance and long flight times with or without the use of power. And, there’s no Hi-start or cumbersome launch system to worry about. The high-power brushless motor and folding prop combination provide outstanding efficiency so you can enjoy soaring and sport flying in the same flight, plus the ability to climb and find thermals multiple times between battery changes. Key Features: Flite Test crew approved including their exclusive trim scheme design Integrated high-visibility LED lights feature 100+ color, sequence and timing combinations Fully-molded horizontal tail for improved durability, performance and LED integration Transparent canopy hatch is magnetic to offer easy battery compartment access Bolt-on, two-piece wing with carbon-fiber wing joiner rigidity 30A ESC plus a high-power brushless motor with folding prop Lightweight and durable composite reinforced EPO construction No glue required for assembly–can be ready to fly in less time than it takes to charge a battery BNF Version also features: Spektrum 6-channel receiver with industry-leading DSMX® technology AS3X® technology for smoother flight performance in windy and high lift conditions Optional-use SAFE® Select technology makes it even easier to fly than ever before Integrated LED Lighting: Embedded into the airframe is a factory-installed LED light system that practically provides even better orientation than when flying in daylight. Multi-colored light strings operate through a built-in controller that offers 100+ different color, sequence and timing combinations, and are conveniently powered by a 3S 1350-2200mAh flight battery. You can even use the onboard switch to turn them off when flying in daylight. Flite Test Approved: The original Radian® 2-meter motor glider was already popular in the Flite Test community, so E-flite and the Flite Test crew partnered together on the Night Radian FT to finalize its unique capabilities and appearance–including the exclusive, Flight Test-designed trim scheme. The result is a more versatile aircraft that almost any RC pilot can appreciate and enjoy flying. Lightweight & Tough: The redesigned horizontal stabilizer is fully-molded to feature an airfoil shaped cross-section and integrated LED lighting. Construction with composite reinforced, molded EPO material delivers a lightweight yet durable airframe that delivers a unique airplane that’s easy to maintain and offers the best flight experience possible.

  14. From E-flite: VTOL (Vertical Takeoff and Landing) RC models are usually a mixed bag when it comes to performance. If they are stable, their speed and agility is often lackluster. If they are nimble, pilots have to work harder to transition between multirotor and airplane flight. The E-flite® Convergence® VTOL aircraft change all that. Their unique designs and exclusive flight control software give you the best of both agility and stability while making the transition between multirotor and airplane flight so simple and predictable that you will feel comfortable and confident even on your first flight. The E-flite® Mini Convergence® VTOL is a more compact version of its larger counterpart that you can fly in more places and smaller spaces—including indoors. Its smaller size, quiet brushless motors and refined flight control software makes it less intimidating and easier to fly in multirotor mode indoors, plus it’s easier than ever to transition between multirotor and airplane flight outdoors. The Mini Convergence uses a simple and sleek delta-wing design with three brushless motors—two rotating motors on the wing and a fixed-position motor in the tail. In multirotor flight, the wing-mounted motors rotate up into the vertical position to provide lift and flight control along with the motor in the tail. In airplane flight, the wing-mounted motors rotate forward into the horizontal position and the model’s elevons take over pitch and bank/roll control. You also get impressive yaw control in airplane flight with differential thrust from the motors. Sleek and Simple Unlike more complex VTOL aircraft that rotate the entire wing and require as many as four motors to achieve vertical and forward flight, the Mini Convergence uses a simple and sleek delta-wing design with three brushless motors—two rotating motors on the wing and a fixed-position motor in the tail. In multirotor flight, the wing-mounted motors rotate up into the vertical position to provide lift and flight control along with the motor in the tail. In airplane flight, the wing-mounted motors rotate forward into the horizontal position and the model’s elevons take over pitch and bank/roll control. Yaw control in airplane flight is provided by differential thrust from the wing-mounted motors. Exclusive Flight Control Software Makes it Easy At the heart of it all is updated and refined flight control software that has been expertly tuned by our engineers. The end result is more consistent and reliable flight performance that makes it even easier for almost any RC pilot to experience the fun of VTOL flight. Automated Transition Making the transition between multirotor and airplane flight is as simple as flipping a switch. The flight controller will smoothly rotate the two wing-mounted motors into the correct positions and activate the rear motor as needed. Two Flight Modes Easy-to-use Stability and Acro flight modes deliver a wide range of performance. Stability Mode In multirotor flight, Stability Mode will limit pitch and bank angles and work to keep the aircraft level when you release the sticks. This allows you to take off and land like a pro, even if you’ve never flown a multirotor aircraft before. In airplane flight, Stability Mode will limit pitch and bank angles and automatically return the aircraft to level when the sticks are released for the easiest RC VTOL experience you will find anywhere. Acro Mode In Acro Mode there are no angle limits or self-leveling in any phase of flight. During multirotor flight, the Mini Convergence will handle like a conventional multirotor aircraft that pitches and banks in whatever direction you want it to fly. It can even flip and roll like other multirotor aircraft. In airplane flight, Acro Mode lets you perform a wide range of aerobatic maneuvers including loops, rolls and more. Super-Simple Setup This Bind-N-Fly® Basic version can be flown with any full-range, 6+ channel Spektrum DSMX® compatible aircraft transmitter and comes equipped with a Spektrum serial receiver that is factory-installed and connected to the flight controller. No complex transmitter setup or programming is required. Your “GEAR” switch is used for selecting Stability or Acro Mode and your “AUX 1” switch is used to transition between multirotor and airplane flight. Customize Your Trim Scheme The included decals give you multiple trim scheme themes to choose—from classic to sporty and even military inspired. Or you can easily personalize your trim scheme by using a combination of decals, paint or both. FPV (First-Person View) Ready For an FPV flying experience like no other, the Mini Convergence is set up to accommodate the recommended FPV camera and VTX (Video Transmitter) Features: Multirotor versatility and sport plane agility Takes off and lands vertically in small areas Compact size so it can be flown in more places and smaller spaces, including indoors Exclusive and refined flight control system makes it incredibly easy to fly Automatic transition between multirotor and airplane flight Stability and Acro modes provide a wide range of flight performance Super-simple transmitter setup—no complex programming required Spektrum serial receiver with industry-leading DSMX® technology (EFL9350 only) Powerful brushless motors compatible with 3S 800mAh batteries Outstanding speed, climb and aerobatic performance Included decals offer multiple trim scheme options Lightweight and extremely durable EPO airframe FPV-ready (recommended camera and video transmitter sold separately) Needed to Complete: Full Range 6+ Channel DSMX Transmitter 800mAh 3S LiPo flight battery Compatible LiPo charger Serial Receiver with Diversity (EFL9375 only) What’s in the box?
