Hello guys, just so you know I'm 15 and this is my first article, so please don't be mean if it's not much good. anyway,
Have you been thinking about getting into discus launch gliders, but don't want to spend $400 on a composite dlg or even the $80 for an alula? here's the solution: build one yourself! the techniques I used were fairly simple, and the wings are similar to the wings of the baby blender, but instead of making crease lines to allow the top sheet to fold over, the top sheet is skinned on the inside so that it can create a fluid curve.
the wings are 30" long each, with a 6" chord and a 1" control surface. fuselage is just made from a few pieces of foamboard glued together with a balsa hatch on top, hinged with tape and held down with a rubber band.The boom is about 24" long, and is made from a bit of scrap balsa. the tail is just simply cut from foam, and the pylon the horizontal stab sits on is the case from a 6-ch orangerx (could easily be done with a balsa rectangle if you don't have a 6ch orx.)
it uses 4 hxt900 servos (2 in the fuse that go back to the elevator and rudder, and 1 for each aileron. using a 750mah 3s lipo with a bec (would work fine with a much smaller battery, as it's pretty nose-heavy on this setup, but it's all I had laying around) for the battery and a frsky rx. it flies pretty well, launches are around 60 feet or so. If you guys want, I may be able to do a build video for version two (which will have a carbon boom and a more aerodynamic pod.)
