The Duo Discus is the current two-place sailplane in production at Schempp-Hirth in Germany. Itís triple-taper leading edge and forward swept wings span 20 m giving it a glide ratio of 45:1 and a wonderful graceful appearance in the air. Although it has performance similar to the original single place Discus, this glider was designed for training, making it more forgiving and very popular with the pilots.

With a span of 4 meters this 1:5 scale Duo Discus is one of our finest Super Scale gliders.  The cockpit comes completely finished with control columns, upholstered seats, seat belts, and many other scale details such as instrument mushrooms complete with instruments. The true to scale canopy is hinged sidewise and includes preinstalled working sliding windows that allow access to the canopy locking mechanism.  All that remains for the builder to do is add one or two scale pilots for complete realism.

The wings and all control surfaces are of very accurate hollow-molded construction. The well-proven HQ airfoil gives this fine model its smooth and versatile flying characteristics. This model is comfortable on a slope and can be winch launched but is at itís best when aero-towed. Its thermalling performance is exceptional and the wings are sufficiently strong to withstand some aerobatics. Like its full-scale counterpart, the forward swept, triple tapered wing plan form looks especially graceful and unique in the air.

For even greater scale realism, an optional fully installed Up-and-Go system is available that will allow for ROG takeoffs and multiple climbs to soaring altitude. The unit comes preinstalled, just behind the wing. Fuselage strength has been maintained by mounting the unit in a carbon fiber box and using carbon fiber bulkheads for additional strength. The up-and-go unit itself is constructed of molded fiberglass making it strong and light. Pre-hinged doors, and a special servo to raise and lower the unit are included. This set-up makes this sailplane ideal for the scale flyer who does not have access to aerotow. Call us so we can recommend the motor, battery and speed controller combination that will give you the performance you are looking for. 

With the level of completion of this glider, only a few hours of work are required before it will be ready to take to the air. The wings and control surfaces are hollow molded and completely finished. Airbrakes are installed and ready to be connected to your servos. The high gloss, gel coated Fiberglas fuselage has the wing joiner carrying tubes and the rudder control tube installed. As well, the functional retract, tail and nose wheels, and a fully functional aero tow release are installed.  Decals are applied. A small package of hardware and building instructions complete the kit.

Radio requirements are two micro servos for the ailerons, two micro servos for the airbrakes and four regular servos for the elevator, rudder, retract, and tow release.
