As they become available they will be uploaded and a download link will be put up here on this page. (99 cm.) I was however not happy with using the supplied plastic guides as my experience of gluing to plastics is poor. I also used a neater, more maintainable and lighter servo mounting system. Equipped with a balsa glass reinforced removable horizontal stabilizer. RC Discus Launch Gliders (DLG) are usually small to large sized radio control sailplanes that are propelled using a discus launch method from the wing tip of the dlg RC glider. I did several things differently to the instructions in order to save weight and make a neat installation. It doesn’t make any sense to spend a significant amount of money on this project before it is something of long term interest. The battery would be furthest forward. Hence in order to sand the rudder slot vertical I had to use a straight edge on the main wing mount as a reference – having also checked that this was representative of the main wing position. Side Note: If you are following the above blog, you will see this project is a One Off Custom Design and all Hand Cut. Discus Freeflight Handlaunch Glider Photos An AMA Glider Original Article Due to it's low weight, with a scant wing loading of 2 I had started with a cheap HobbyKing model with conventional covered balsa wings which was great for testing interest but was higher drag and hence gave poor launch heights. I explored options, including getting a replacement fuselage, but the rudder was also a little thicker than design and it looked like careful trimming could lead to a fit. For RC glider enthusiasts, these are some of the best free plans that are available for download. Additionally, there's a newer form of HLGs known as Discus Handlaunch or DLGs. There was also room for my very small altimeter/variometer next to the receiver. I could then use a straight edge from here to the tubes at the front of the boom to place the pieces of masking tape. So I decided to use 4mm wide strips of 0.5mm carbon sheet to span the servo tray at each mount and then epoxy small aluminium blocks tapped for a #0 UNF screw that was the right size for the servos. Wing Area: 275in 2 (1774 cm ) Weight: 8oz. The Blaster 2 has an all moving tailplane mounted on a carbon V mount. The second launch mode maintains the glider in a straight climb. We have started a project to do just that, and you can follow along here. This flyer type is must-have, as it allows for the ability to fly something in many different locations and situations. The first design is underway. Did you make this project? BETA 2.3: FOUNDATION UPDATE - Compass Fixed (N,S,E,W). A Discus Launch Glider (DLG) is a radio controlled model sailplane launched using a 'discus launch' in which the glider is held by a wingtip and the flier rotates rapidly before release. I now need some more fine days to learn how to get the best out this great plane. This is a little faster than a discus (~55mph) but the glider is 6 times lighter. I rounded all the edges of the V mount to hopefully lose a tiny bit of weight and drag (I don’t suppose very much). They have the Blaster 2 in stock right now - but be aware these can go quite quickly. To launch one holds the glider by a finger grip on a wing tip and then one spins around as throwing a discus. The top of the climb is detected by a script running on the transmitter that monitors the altitude. This switches the flight mode from the launch modes to the selected normal flying modes of cruise, speed and thermal (set via a 3 way switch). That is a nice looking Glider, nice plans Doug May 27, 2008, 03:04 PM #4 Devine Devine Registered User Wow As you probably know we are flying in Holland a national championship F3K mini. This position was found with rudder fitted loosely. Rudder movement has a small coupling to the ailerons to make turns easier. To do this, we must learn about Laser cutting! However given the uncertainty on whether I would get the rudder vertical I did the filing of the rudder slot first and then fixed the elevator mount, followed by gluing the rudder in place. The design has these running on the outside of the tail boom. Its wing could also be built as a polyhedral version. This model is the most expensive in my fleet by some margin and hence the approach to the build was ‘If a job’s worth doing it is worth doing right’. Discus launch version of the Colibri glider. One wingtip is equipped with a “launch peg” which is gripped with two fingers. Things have come on a bit from my first transmitter that just had one button! I double checked space using pieces of card with different diameter holes for nose diameters at the servo positions. During the Spring and Summer months, more flying than designing occurs and even less updating the site with progress info. The only option for the other was to get a long aerial lead and place it in the wing. The ELF is a small discus-launch glider ideal for sport flying while on travel or in your neighborhood park. In particular I mounted all 4 servos in the nose to reduce the nose weight required and hence reduce the overall weight. We have received many inquiries asking us if we’ll consider making this a short kit if successful. This past winter I built a discus launch free flight glider known as the Maxima 30 designed by Len Surtees. Feb 13, 2021 - Explore Malcolm Bond's board "DLG Discus Launch Glider F3K", followed by 120 people on Pinterest. I have described this as if done after the elevator mount. See photo below: The elevator and rudder servos where mounted on top of the servo tray, behind the battery: The aileron servos were mounted in the underside of the servo tray: With the servo positions set and the maximum arm lengths known I could set the lengths for the rudder and aileron horns. The first launch mode has a slight up elevator to rotate the glider from the horizontal discus launch to a climb. So the first question was ‘which battery was I going to use?’. The Discus Launch Glider, or Hand Launch Glider, on the other hand, finds itself in all airplane categories, including Indoor and Outdoor, along with several sub-categories within, such as Free Flight or Radio Controlled. THE RC DISCUS LAUNCH GLIDER … (updated February 15, 2021)Our apologies for the lengthy wait. I then did a bunch of drawings with servo positions, potential servo arm lengths and push rod routes. This enables immediate action if the model is not quite setup correctly. I prefer epoxy to cyano as it gives a longer handling time and a stronger joint. (It's called a Discus Launch Glider/DLG) So I've decided to build one from a plan. I have 5 flight modes (trim settings), two for launch and three for normal flight. This was fitted later when I knew what pushrod movement I could get from the servo and hence the size of the rudder horn, and hence the amount of offset required: The all moving elevator link was straightforward (well something had to be!). Unwinding With a Free Flight Discus Launch Glider For me the model aviation hobby stays interesting if I take on new types of projects which present new challenges. (127 cm.) Wingspan: 50in. Kid" hand. There is also a switched link from elevator to flap to give better aerobatic performance if required. I noticed that the attachment screw did not rest flat on the upper surface of the tailplane/elevator. All rights reserved. Some of these planes have a pin glued securely near the tip of one of the wings. However mounting servos horizontally rather vertically also makes good use of the space in a nose cone. Discus-2b Glider is a Microsoft Flight Simulator 2020 mod created by Aerosoar. Discus Launch Glider RC Aircraft Plans and Templates This page will hold all templates and downloadable build information made available from our Discus Launch Glider Plans Project . The control horns were all replaced with lighter carbon ones and their length was carefully set to match the servo arm length and movement that was possible within the confines of the nose cone. The mount has to be fitted before the rudder as it slips over the boom. Please send us a note if you would like to be notified when available for order. DL50 Discus Launch Glider DL50 Specifications Length: 39 in. In both cases I used slightly longer horns. I had the screws from a 250 size helicopter. I had masked off the rudder around the joint and the outside of the boom before assembly to aid removal of a small amount of surplus adhesive. I had also already bought the servos and had opted for the version designed for mounting flat rather than upright (KST X08H v3 HV). So I decided to use 2mm OD carbon tubes (1mm ID) and file a flat on one side to both get the rods closer to the boom and provide a flatter surface to glue and hence save a tiny bit more weight. 0.5mm carbon is plenty strong enough. To launch one holds the glider by a finger grip on a wing tip and then one spins around as throwing a discus. We offer our original articles, some articles submitted by others, plans for numerous gliders, and much more! ARRIVING SOON! Micro F3K Size RC Gliders Radio Control DLG hand Launch Discus Launch Airplane Sailplane Hobby Grade Kit Balsa Wood Carbon Fiber MicroBirds The Feather² Squared come with a step by step HD video build guide, providing simple and easy way to learn and follow directions, building your glider from start to finish. You can adopt as much or as little of what I have done as you wish. These models are commonly known as DLG’s, which is short for “discus launch glider”, due to their unique launching style. The aim was to have the servos as far forward as possible to minimise the need for nose weight. The kits comes with the moulded wings and fuselage complete and with hardware to build the control linkages. May 2010) Hoosier Daddy (Bruce Kimball's awesome tip-launch glider … Glider Plans Free Flight Links Photo Gallery Video Gallery Contact This is the official website of the DiscUSKid glider design. Below are the templates as they become available, The Goal at If It Can Fly. However the major activity is installing the radio gear and control hardware. Obviously I was delighted to see it fly so well. After the mod the screw presses more evenly on the top of the elevator: The target is to have the trailing edge of the elevator 5mm in front of the leading edge of the rudder. I then progressed fitting one guide at the front and one at the back and then, after waiting to set, moving on to the next pair, gradually getting to the middle. I made a paper tube the right diameter and epoxied it in at an angle so it would be 90 degrees to the aerial in the nose: I made up the battery from a couple of single cells and fitted a balance plug that could be used both for charging and for supplying power the radio. Luckily, we have a forum of over 1000+ flyers we can seek advice on and that is exactly what was done. This looked too messy and heavy to me, plus not easy to remove the servos if they fail. Share it with us! The need for high strength, light weight and clean aerodynamics means that a composite built model is needed. Gaining altitude without the use of a motor is a feeling hard to describe. The design has the rods guided by a series of 10mm long tubes at around 50mm spacing. This page will hold all templates and downloadable build information made available from our Discus Launch Glider Plans Project. This also helped giving a minimal sanding of the rudder side of the joint to remove the gel coat and get a better joint. I made the slots in the moving surfaces using a 0.7mm drill and chain drilled against a straight edge. I disbanded this when I realised that the pushrod would need to be more than the standard 1m length. In order to get to 200ft the glider needs to be launched at >80mph, and the g force in the rotation is over 25g. I raised the last guide 0.5mm to help give a smooth run to the horn: This took quite a while to design. I hope some of these will be useful to other builds of DLG kits. I had also sanded the mating surfaces for a good joint. See more ideas about gliders, discus, rc glider. So the weight saving would be small, if any. The aileron servos needed arms as long as possible and hence could be installed underneath the servo tray with their arms going upwards through holes in the tray. This was because the V mount assumes parallel top and bottom surfaces and the elevator was essentially triangular in cross-section from the mounting plate to the trailing edge. It would have been easier to have fixed the elevator mount first and used this as a reference to get the rudder upright. Ventus 3M - Self-launch glider Download the Ventus 3 Brochure for more details The 20 m two-seat Arcus is known for its superb handling and excellent performance has received an update for 2020. Copyright 2021 If It Can Fly. From this it became clear that I would need less nose weight if I put the aileron servos in the nose rather than the wings. I use FrSky radio with their excellent telemetry system. 1 piece of 1/16″ plywood (3″x10″ is sufficient). Up to 3 servo extension wires (battery and aileron servos, depending upon length of wires–I only needed a battery extension). It would look much neater if these were inside. I had seen comments on doing this but no examples– a gap that I hope this instructable fills. Reply Hence shorter flights and less time to find some lift. To launch the airplane you I expect some will feel my approach has been too finicky. I also have a script that records launch height, max height and flight duration plus a graph of altitude vs time to inspect after the flight. I assembled the wings and used a straight edge to mark the line between the rod ends in the horizontal and vertical planes. Contest 2017. The Vladimir's Models Elf is a 1m lightweight mosquito class mini discus launched glider (DLG) that weighs only 95g ready to fly. 1 piece of 1/32″ plywood (2″x2″ is sufficient). Now #GetOutAndFlySomething. A 380mah 2 cell lipo would be big enough. In order to get these guides aligned I cut pieces of masking tape with a hole just bigger than the guides and carefully placed these on the boom before gluing the guides in place. Web is https://www.hyperflight.co.uk (Not sure if Instructables allows links) Mike, About: Engineer, retired. This avoids the need for a voltage regulator – that then saves space and weight and also means a smaller capacity battery can be used (no energy loss from the regulation). I am however very happy and in retrospect would not have done anything differently. So next was a proper discus launch. Download for free to enhance your experience in MSFS 2020. The mount for the all moving tail has to be glued in place. See photo above. These DLGs are launched as if throwing a discus or frisbee. Following on from the standard hand launch gliders mentioned above, a Discus Launch Glider is a newer breed of rc glider that's become very popular with flat-field flyers. Turnabout Plans Discus Glider Video Clip October 2007 AMA Naitonal Record HL Glider 140 Round-A-Bout DLG Plans for the Vartanian 2007 NATS Handlaunch Glider Article Discus Freeflight Handlaunch Glider … To correct this I filed a piece of 0.5mm carbon sheet to make a wedge and glued this onto the mounting plate bottom surface. The aileron horns supplied were 1mm thick which is overkill. It is not vertical as the ailerons need more down movement than up when being deployed as flaps: I had already fixed the battery location and there was space for the receiver on the underside of the servo tray, below the rudder and elevator servos. The tail control rods are 0.8mm diameter carbon rods. I also used a piece of 1mm carbon rod to aid alignment. I hope this instructable helps others building their first DLG. This is switched out on aerobatic mode. This evolved into a part time business that I still practice. DIY Scratchbuild DLG Discuss Launch Gliders Tips A radio controlled model sailplane or DLG glider Discus Launch Glider in which the sailplane is held by a wingtip carbon fiber peg and spun around and released. These are designed for mounting in wings – that was no longer my plan! In broad terms I followed the sequence of starting at the tail and worked forward: Before starting I weighed and found the centre of gravity (COG) for each of the parts, plus servos, radio and battery. Tricky but worked OK. See photo below for the positioning of the carbon tows. For the aileron control rods I decided to use 0.8mm piano wire - the same as at the ends of the tail control rods. With the gliders weighing around 300g (11oz) the 25g force comes out at 7.5kg or 17lbs – easy to take on a straight arm. Advice was taken and this article will track the progress of building and then learning to … I considered using carbon rods but these would have needed to be a bit bigger diameter (longer free run) and then needed joints to the piano wire ends. As files are complete, they will be uploaded below. It is an extremely popular RC Glider for both new and experienced HLG fliers. I again used epoxy. The rudder servo arm needs to be fairly long for the large rudder movement while the elevator servo arm is short with the small movement of the all moving elevator. Follow this blog to keep track of progress. Also look at my flight later in this instruction.

GBP EUR USD AUD CAD CHF CNY CZK DKK JPY KRW NOK NZD PLN RON RUB SEK TWD ZAR Outerzone's Classy Class C Glider The Classy Class C was designed in 1939 by airplane modeler Elbert Weathers for Flying Aces magazine, an American periodical of avionics-centered short stories, which was popular in the 1920s and 1930s. I had already decided that I would use high voltage servos. I put these into a spreadsheet so I could see where the final model COG was likely to be. See more ideas about rc planes, rc glider, rc plane plans. So I decided to proceed. Masking tape was wound around the boom forward of the mount so it could be positioned easily with adhesive applied. I then made up an offset guide to give some support between the elevator mount and the rudder horn. Feel free to reach out to us if you are looking for more information on a particular hobby! 1 piece of 1/64″ plywood (5″x5″ is sufficient). All links here will be freely available, Enjoy! The build log shows the specific construction and trimming of the V-Tail model and discusses programming options available on the Spektrum DX6i programmable radio. Tip Launch Glider Plans DiscUSKid-36 (A tip-launch tribute to Tom Peadon's legendary U.S. In order to get to 200ft the glider needs to be launched at >80mph, and the g force in the rotation is over 25g. Learn how to build the ELF Discus Launch Glider Kit from Vladimir's Models. It was recommended to take a look at the Hobby King Raven 990 DLGas it’s entry point into this hobby segment is reasonable. Hence it took longer and required a fair bit more planning/checking with the changes implemented. This pin is where you hook your fingers … The instructable here shows my build of a ‘Blaster 2’. Each design will have its own main heading within this page. The carbon strips had pieces of balsa underneath to raise them to the height required. Jan 30, 2021 - Explore Okt's board "模型飛機製作" on Pinterest. Kid) (As featured in Flying Models Magazine! Scratchbuild Discuss Launch Glider (DLG): Definition DLG from Wikipedia: “a radio-controlled model sailplanelaunched using a 'discus launch' in which the glider is held by a wingtip and rotated around the flyer by hand before release. I will be happy to supply the setup file if anyone would like to use it. Love Flying Revolution Kites, Not Your Parents Kite for sure. The thought that one can hand launch a model glider to 100-200ft altitude seems amazing – but is possible with Discus Launch Gliders (DLGs). In order to get the elevator flat relative to the main wings the mount was fitted with the main wings in place and the elevator attached to the mount. Premiere RC sailplane designers and producers specializing in discus launch gliders and electric gliders. The DiscUSKid is a free flight tip launch glider inspired by Tom Peadon's legendary "U.S. (227 g.) Revision History Date Revision Notes/Comments 6/12/2004 Document initial This went well and the video above shows the following flight. It flew perfectly, and kept on going right to the end of our long mown strip. As they become available they will be uploaded and a download link will be put up here on this page. The alignment was checked carefully before leaving for the epoxy to set. It was also around 40% heavier and so came down faster. Especially with kids and young people. The ELF is based on MIT's Dr. Drela's HLG glider design, the Apogee. AMA Glider serves as a resource for model glider hobbyists. Using this method of launching the average flier c… The rudder also has to be attached to the fuselage - that was a bit more difficult with my kit. See below. 3 years ago, Hyperflight here in the UK have a good range of DLG kits. 1 small piece of 1/4″ balsa sheet. Rather than use an on/off switch I glued a socket into the servo tray. Following this design I also reduced the guide length to 8mm and increased the spacing to 55mm to save a bit more weight. Have always had an interest in electronics, often related to radio control. The rudder glues into a slot the rear of the carbon tail boom. Finding the place to drill the exit slots in the nose cone was a bit scary. Where they crossed was the place for the hole - that was elongated as required for the shallow angle of exit. So I added two 60mm lengths of 1mm2 carbon tow starting inside the top and bottom of the boom and the splitting each of these so half ran down each side of the rudder, still inside the boom. I started by fitting the guides next to the elevator mount. The question then was where to place the aerials. I could place one behind the aileron servos pointing away from the carbon parts of the nose. Hence powering up is just a matter of removing the nose cone and plugging the battery in: The radio setup was the most complicated I have ever done.
