Description

Elf Mini DLG

The Vladimir's Models Elf is a 1m lightweight mosquito class mini discus launched glider (DLG) that weighs only 95g ready to fly. Being so light no effort or rotation of the body is needed to throw it, and even an unfit and arthritic person like myself can launch it to 25m very easily (and with no aches the next day). After a brief dusk trimming session I caught a thermal and specced out on the very first launch on the first daytime flight - the feeling of accomplishment is really brilliant!

The model is an update of Dr Mark Drela's ground breaking Apogee design and performs wonderfully as a small field DLG model or even a micro slope soarer. Built to Vladimir's Models incredibly high standards, the kit is very highly prefabricated with the wing, fin, and tailplane finished. Only the simple pod and boom fuselage requires a little work. Assembling the Elf and fitting the RC shouldn’t take more than a couple of evenings.

The one piece wing uses free flight type construction techniques, to maximise strength and stiffness, and minimise weight. The wing’s front part is a beautifully molded carbon Dbox for good torsional strength and excellent aerodynamics. The substantial spar is made from carbon spar caps with vertical grain balsa shear webs. The balsa ribs are connected to the thin carbon trailing edge using carbon capstrips, and aft of the spar is covered with film. The Dbox is beautifully curved, and at the wingtips there is a slot for bonding in the launching winglet.

The pod and boom fuselage uses very neat transparent plastic moldings for the pod and sheath nosecone. These are an excellent fit and follow the wing underside contour for a gap free fit. The tailboom is a tapered wrapped carbon tube with a pre-cut slot for the fin, and a flattened front section for mounting the R/C equipment. The fin is made from rigid foam with carbon spars and has smooth vac-bagged glass covering, and incorporates the rudder with a very free living hinge. The all flying foam/carbon/glass tailplane is mounted above the boom using a tiny V mount to minimise drag and allow it to be pivoted for excellent control. All pushrods and accessories are included, only the R/C gear and minimal building equipment is required.

The Elf is supplied almost completely finished. The fuselage now comes with the V mount, pod and pushrods already fixed in place. All that is required to finish the model is to glue the fin, tailplane and launch peg in place and fit the RC.

Beginners, we highly recommend the Elf as a first hand launched glider - because it is easy to fly, is reasonably crash resistant if flown over log grass, and has superb performance. It doesn't require much assembly - just gluing on the tail, and fitting the radio control. We have created a Best Hand Launched Glider for Beginners topic on our forum, giving more info for beginners. Please post there if you have any comments or questions.
