Mr. Lampich left the company and went to Austria;
The first aircraft in the framework of the MSRE was L1 Mama's favorite, designed by Árpád Lampich, and the 12 HP engine by Péter Thorotzkai. The next aircraft, the L2 Rome, flew three world records in its category. After Rome, L4 Bohóc was built. This biplane, made of wood, was also suitable for aerobatics. Árpád Lampich, the talented and successful designer, took part in the design and production of the BL 5 and BL 6 aircraft, but then he continued to work in Austria, where, e.g. he designed the LN-XXI and LN-XXII types of sleek biplanes. Lajos Rotter, who started with MSRE, but started an independent business, founded FEIRO with the Feigl brothers. By 1924, the small passenger plane FEIRO I was ready, a significant innovation was a solution suitable for equalizing the steering force. In the next step, a more powerful engine was built into the aircraft, thus the FEIRO Crane was born. The FEIRO Dongó two-person training aircraft did not receive a government order due to its relatively weak engine. With this, the activities of the company FEIRO ceased. Lajos Rotter reappeared with the glider named Karakán (1933), with this plane they flew for the first time in Hungary over a distance of more than 50 km. He designed the next glider together with Zoltán Janka - it became the Vándor. The glider named Nemere was completed in 1936, with which Lajos Rotter won the Olympic championship with a world record flight in Berlin.
