      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.

      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!

      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.

      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.

      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:

      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.

      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.

      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.

      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.
      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.
      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.
