As the membership of Akaflieg München expanded a requirement for more glider training capacity emerged. To provide the extra capacity, students at the Akaflieg designed and built the Mü4 München, ensuring that the aircraft had trouble-free handling and was easy to maintain and repair. Despite the simple gliders low performance it was found that the Mü4 München was capable of soaring flight and so was used for mountain flying in the Alps near Rosenheim.
