From October 1025, 1921, Schulz tried to participate as a novice in the 2nd Röhn Competition, but his machine was rejected by the competition committee. However, he made eight flights outside the competition from the Pelz slope. In one of them, he covered the 365-metre route in 46 seconds. Schulz was awarded a consolation prize of 1,000
Deutsch Marks for his "daring flight". By 1924, Schulz had built 10 different gliders according to his own designs, including aircraft with an auxiliary engine. Of the gliders constructed in
Königsberg, the most famous were the "FS 5", "FS 9", "FS 10" and "FS 3" - known as the
Besenstielkiste. It was very simple in its construction. Made of broom handles, strips, sheet metal, wire and canvas, it gave the impression of being very primitive. On May 11, 1924, during the 2nd Coastal Gliding Competition in
Rossitten, Schulz flew the glider "FS 3" for 8 hours and 42 minutes, which was a world record at the time and became a direct impulse for a small group of gliding enthusiasts to establish the Aviation Association in
Willenberg near
Marienburg. On May 20, 1925, with the support of Schulz himself, the "Westpreußischer Luftfahrt-Verband" was established, with its headquarters in
Marienburg. In autumn of 1925, a group of German pilots was invited to the 3rd All-Russian Gliding Competition, which took place from 1 to 10 October in
Crimea. This group also included Ferdinand Schulz, who flew the "Moritz" performance glider. In this glider, on October 2nd Schulz set a new world record in a long-distance flight in Crimea, lasting 12 hours and 6 minutes. Reaching an altitude of 405 m above sea level, he achieved 2nd place in this competition. After returning to
Rossitten, he founded the Gliding School. On 3 June 1926, Schulz, together with Heinz Reichardt, spent 9 hours and 21 minutes in the air. It was not until 1937 in
Sylt that this record was improved by Ernst Jachtmann and Flossdorf in the "RM 4" glider to 13 hours and 59 minutes. On January 1, 1927, Schulz was given a job as a teacher at the primary school in
Marienburg-Sandhof. He settled in Marienburg at the "Kurfürsten" inn (today Bar Puchatek located in Plac Gdański 7). He could now personally supervise the expansion of the glider airfield in the
Willenberg county, as well as continue to actively participate in international competitions. On May 2, 1927, he took part in the 4th Gliding Competition in
Rossitten. He took off in the glider "Westpreußen" - belonging to the "Westpreußischer Luftfahrt-Verband" and built in
Marienburg in 1926 especially for Schulz. On the first day, he broke another record - he flew for 14 hours and 7 minutes. Two days later he broke further records: the altitude record in a shuttle flight (it was 560 m above sea level) and the speed record, which was 54.45 km/h. On May 14, 1927 he set a new record of 60.2 km/h. The most interesting flights were made in his home area – in Willenberg. One day in May 1928, a strong north-westerly wind was blowing at a speed of 14 m/sec., which lifted Schulz to a height of 650 m above sea level, he decided to visit
Marienburg. The inhabitants of
Marienburg looked at him with amazement, when he suddenly appeared over the castle and the city, flying over it at a height of 150 m above sea level. He spent a total of 4 hours and 1 minute in the air over the city. A month before Schulz's 36th birthday, on November 18, 1928, the residents of
Marienburg erected a commemorative stone for their distinguished fellow citizen on the edge of the
Marienburg-Willenberg glider airfield. It was a granite block with the inscription: "Segelflieger Ferdinand Schulz - 1928". Two days later, Schulz obtained the qualifications to perform aerial acrobatics. == Death ==
