The AG37 is thinner which positively affects the launch height and was specially designed by Mark Drella for build-up glider wings w/o ailerons or flaps. It features a better wing construction which is more optimized for discus launch and also has an option for using AG37 airfoil instead of Selig 3014 used in the original model. However, considering that it was designed for “javelin launch” (HLG) instead of the discus launch (DLG), I’d recommend looking at the updated model called The Lightning Bug. The original plan from the ’00s is available on Outerzone. Additionally, it needs only 2 servos that lower the value of the gears that you use for this glider. There are no ailerons but with the dihedral of the wing, it steers greatly with the Rudder and Elevator. It features a wide oval wing that maximizes the wing area at and handling performance. It was designed back in the ’00s as an HLG with a V-Tail and modified for the discuss launch after. This is actually a Mosquito-Class glider so the wingspan is only 0.75 meters. The Bug is a glider that hooked up a lot of pilots around the world to start flying DLGs. These are easy to build, use widely available materials, mostly use only the rudder and elevator for steering, and perform great overall. We’ll be looking at the balsa constructions mostly. These usually use balsa and carbon tubes which you can easily source from a local hobby store. Mini DLG Glider Plansįirst of all, let’s check the small DLG glider plans for a 1-meter wingspan and a 0.75-meter wingspan (Mosquito-Class) model. This has a direct influence on the performance of the wing and the whole glider as a result.Īdditionally, if you compare the price of your potential build and a kit – in some cases, the difference is very minor.īut buying a DLG kit will save you a lot of time, require a smaller tool kit, and will provide the best performance, compared to home builds. If you are willing to build a 1.5-meter, consider making a composite wing in order to have a decent model.Īlso, if you don’t have not a lot of experience with composites, or just prefer to buy a ready-made kit, check out the Hawk, and Falcon.Īll these can be purchased as Kits, so you will still have to do some assembly and install the control horns, pushrods, pull cables, servos, etc.Īnother benefit of the modern DLGs is the airfoil accuracy compared to the built-up gliders. So, if you are looking for the balsa build, I’d recommend going with the 1-meter DLG. They will give you a chance to start and everyone at the local field will welcome you with the balsa DLG to join the competition.īut if you wish to perform on a good level against the others, once you get some flying practice, the bagged or molded 1.5-meter wingspan DLG will be a must.ġ-meter models might be using balsa as the main building material as on the smaller wingspan you can manage to build a relatively stiff model that will survive close to a 40-meter launch. You can find some free DLG glider plans available online though. There are some bagged models as well, but they are becoming rare guests at the competitions as time goes. So, that’s why most of the recent DLG gliders at the F3K competitions are full carbon, pressed in molds. This type of launch applies extreme linear and torsional forces to literally all the parts of the glider and raises the bar for the build quality and construction. The main “issue” with the built-up DLGs is the lack of stiffness, compared to the molded carbon models.ĭiscuss launch gliders mean to be launched by a pilot holding the glider by the wingtip, spinning around to create momentum, and releasing the model at the end of a spin. Additionally, there is plenty of info on the building and tuning of these models. Luckily, there are a few sources around the web, where we can find some detailed DLG plans which are publicly available. However, the combination of features of a modern DLG glider has raised the price tag up to $1000 for a 1.5-meter model… and ofc, manufacturers keep their DLG glider plans private. DLGs or discuss launch gliders, gained a lot of popularity lately, for the size and performance they offer.
