Models and versions
There are three different gliders by the firm Schempp-Hirth modeled in
this project, all from their Discus line. The Discus is popular with clubs
all over the world. They are strong and relatively easy to fly but the
performance is amazing when they are flown by a good pilot.
The base model is the Discus B that is a pure glider. But we included
two models with auxiliary engines. The Discuss BM can use its engine
to take-off, the BT has a smaller engine that is only used in flight and
needs to be towed or pulled into the air. Note that the BM is rare, only
9 or 10 of these have been built.
