This is a livery for the LS-4 developed by MADolo and B21.

The real model is an LS4-a which is operated by the Segelfluggruppe Isartal at Koenigsdorf.
It is named after Erhard Samper (1923-2016), founder and instructor at the Segelflugzentrum (Soaring-Center) Koenigsdorf in Southern Bavaria.
In the 1950's He started training with young people using an SG-38 glider started by rubber bands. 
In the 1960's he initiated the development of the new glider airfield right between Munich and the Alps.
