The SG 38 was designed to be a training glider for basic flight training by the Nationalsozialistisches Fliegerkorps (NSFK). The usual launch method was by bungee cord from a sloped hill. Because training was conducted solely by solo flight the aircraft had to be very easy to fly and also easy to repair.

The high-wing design uses a kingpost and cable bracing. The primary structure of the glider is of wood, with the wings, tail surfaces and inverted "V" kingpost all finished in doped aircraft fabric covering. The pilot sits on a simple seat in the open air, without a windshield.

The basic configuration was similar to earlier gliders such as the Stamer Lippisch Zögling and the Grunau IX, but the SG 38 was an entirely new design. Improvements included enlarged tail surfaces for better stability, a separate skid mounted on shock-absorbing springs, and an updated seat for the pilot.

The SG-38 played a critical role in pilot training for the Luftwaffe in the Second World War, as a simple, but robust, trainer for the rapid increase in the number of pilots needed by Germany. It was commonly flown by bungee launch on the slopes of the Wasserkuppe.

From 1949 to 1951 Spain's AISA produced 50 licence-built aircraft.[4]

In the UK, Elliotts of Newbury built a copy of the SG.38 called the Elliotts Primary EoN; its version first flown in 1948 and used by the RAF as the Eton TX.1.

Allstar SZD-59 Acro for Vehicle Simulator (c) Ilan Papini

This is the model of the polish SZD-59 Acro in the aerobatic configuration (short wingspan: 13,20m).
The SP-3886 belongs to the Allstar company and is the demonstrator of the reworked SZD-59-1 from 2017.

The model has smoke, press CTRL+S to use it.
You can open tha canopy by pressing CTRL+D.
Like the original, the VSF-model has full aerobatic capability: You can do flicks, spins, tailslides...
Care for the g-limits and the speed, the SZD-59 accelerates quick on downward lines.

Good speed for flick rolls is ~155 km/h.

The 3D model was made by Thomas Brückelt.
Pascal Dumat transferred it into the Vehicle Simulator, added animations, the pilot
and instruments.
Thomas Brückelt made the flight model and painted the textures.

Here you find two videos made by Thomas Brückelt of the real one, together with nice wooden decoration

The Messerschmitt S9 was an unsuccessful experimental glider from 1921 Because of lack of aerodanamic stability it crashed on the first flight.

Of cause in VSF center of gravity is in the right position and you can fly it.

Bungee launch is simulated: Place the S9 on a hill. Use the Map; press "M" and move the crosshairs to the place you want to start your flight and press "Go to".
Give full throttle and after that press "E" to start your flight.

You can also use the two prepared Situations "Messerschmitt S9" and Messerschmitt S9 Thermals", coming with this model.

The project was inspired by Matthias Simon from www.airmodel.de.
There exists only one fotography, no technical datas or drawings. So the 3D model was redesigned just by using the picture by Thomas Bruckelt.
Pascal Dumat transferred it into the Vehicle Simulator, added animations, the Pilot and instruments.
Thomas Bruckelt made the flight model and painted the textures.

Jump back in time to the beginning of aviation and enjoy!

The model of the Schleicher ASK-21 shows the D-3868, used by the "Forderverein fur Segelkunstflug im BWLV", a club for aerobatic gliding in south / west Germany.

The ASK-21 is good for basic aerobatic, it's easy to control and uncritical.
Because of its gentle flight charcteristics and its structural strength the ASK-21 is used in many clubs as training aircraft.

The maiden flight of the ASK-21 was in 1978.

Enjoy this famous, little areobatic glider!

Pascal Dumat prepared Wolfgang Pipers original ( http://www.fsglider.de/p_e.htm ) model for Ilan Papinis Vehicle Simulator.

Some details, pilot and animations were added to give a realistic impression of this beautyful historic aerobatic glider (originally designed in 1936 by Hans Jacobs).
Thomas Bruckelt made the flight model according to his experiance with the real glider.

The D-6868 was built by some members of the German aeroclub FSV Vaihingen https://www.fsv-vaihingen.de/technik/habicht/.
They started building the glider in 2004.

For aerobatics it´s recommended to set the trim to -4.0.
A good speed for flick rolls is 140...150 km/h.

The airbrakes are relatively ineffective, for landing you need to sideslip (move aileron and rudder in opposite direction to get a higher sinkrate).

The model is equipped with smoke: Press CTRL+S to activate it.

The D-8849 "Gilb" belongs to the "Forderverein fur Segelkunstflug im BWLV", a club for aerobatic gliding in south/west Germany: www.segelkunstflug.com
 
The Lo-100 has no speedbreaks, so you have to make a side slip to rise the sinkrate for landing.
Therefore keep the nose above the horivon, move aileron a bit to one side, and right after that the rudder to the opposite.

See the screenshot "Lo-100_sideslip.jpg" in the Lo-100_Gilb-folder.
Maximum speed for flick rolls: 130 km/h

The model has smoke on the wingtips, you can switch it on/off by pressing CTRL+S.
To open/close the little window of the canopy press CTRL+C.

The Standard Cirrus was designed by Dipl. Ing. Klaus Holighaus and flew for the first time in March 1969. It is a Standard Class glider with a 15 metre span and no camber-changing flaps. The all-moving tailplane, a feature of many designs of that period due to its theoretically higher efficiency, caused less than desirable high-speed stability characteristics, and so modifications were made to the early design. Even so, the glider is still very sensitive in pitch.

Improvements were made with the Standard Cirrus 75. These included better air-brakes with an increased frontal area. By April 1977, when production by Schempp-Hirth ended, a total of 700 Standard Cirruses had been built, including 200 built under licence by Grob between 1972 and July 1975. A French firm, Lanaverre Industrie, had also built 38 Standard Cirruses under licence by 1979. VTC of Yugoslavia also licence-built Standard Cirruses, reaching approximately 100 by 1985.

The Cirrus K was made out of the Standard Cirrus in the end of the 1980s. Wilhelm Duerkop (better known as "Salzmann") started to realize his idea of an easy to handle aerobatic glider, basing on a standard glider, so that development saves costs and makes it interesting for gliding clubs.
The wingspan was shorted to 12,60 m, the fuselage is enstrengthed and the tailplane was completely changed. It has full aerobatic capability, the g-limits are +7 / -5, Vne is 290 km/h.

Two Cirrus K were built. The D-4747 was the first one and is used by members of the "Foerderverein Segelkunstflug" (aerobatic flying club of south/west Germany). The other one is the D-3092 which is in private use and has little improvments.

The Schneider Grunau Baby (named for the town where Schneider's factory was located - now Jezów Sudecki in Poland) was a single-seat sailplane first built in Germany in 1931, and with some 6,000 examples constructed in some 20 countries, is the most widely-built sailplane to date.
It was relatively easy to build from plans, it flew well, and the aircraft was strong enough to handle mild aerobatics and the occasional hard landing.
When the Baby first appeared, it was accepted wisdom that the pilot should feel as much unimpeded airflow as possible, the better to sense rising and falling currents of air, temperature changes and the like.
