They started work while studying at Warsaw University of Technology. In December 1925, with some other student constructors, they set up workshops at the Aviation Section of Mechanics Students' Club (Sekcja Lotnicza Koła Mechaników Studentów), where they manufactured their first designs. From 1926 they designed several aircraft alone (Drzewiecki JD-2 and WR-1), in 1928 they joined forces as one team, starting with RWD-1 sportsplane. Apart from building planes, J. Drzewiecki was a test pilot of their designs, while S. Wigura flew as a mechanic in competitions. In 1930 the team was moved to new workshops at Okęcie district in Warsaw, near the Okęcie aerodrome, today's Warsaw International Airport, founded by the LOPP paramilitary organization. On 11 September 1932, Stanisław Wigura died in an air crash in the RWD-6 during a storm, but the RWD name continued to be used for new designs (according to a popular story, the letter W now de facto stood for engineer Jerzy Wędrychowski, but he was not a designer). In 1933, Rogalski, Drzewiecki and Wędrychowski founded the company Doświadczalne Warsztaty Lotnicze (DWL, Experimental Aeronautical Works) in Warsaw, which became a manufacturer of further RWD aircraft. Apart from Rogalski and Drzewiecki,the construction bureau employed designers Tadeusz Chyliński,Andrzej Glass (2003).
