[edit] Development
The RWD-2 was constructed by the RWD team of Stanislaw Rogalski, Stanislaw Wigura and Jerzy Drzewiecki in Warsaw. It was a development of their first design RWD-1. Its feature was a unique, fish-shaped fuselage, with good aerodynamics, but without a direct view towards forward from the pilot's seat. For this reason, they were later called blind mice.
The first prototype (registration SP-ACE) was completed and flown by the designer Jerzy Drzewiecki in July 1929. In August-September 1929, Franciszek Zwirko and Stanislaw Wigura flew it across Europe, on Warsaw-Paris-Barcelona-Warsaw 5000 km route. On October 16, 1929, F. Zwirko and Antoni Kocjan set an international FAI height record of 4,004 m in the light tourist plane class (below 280 kg / 616 lb empty weight).
Since the design appeared quite successful, three more RWD-2s were built in 1930 (registration SP-ADJ, -ADG, -ADH). These aircraft took part in Challenge 1930 international touring planes competition in July. Stanislaw Plonczynski took the 19th place, as the best Pole (for 35 classified and 60 starting crews), and E. Wieckowski took the 21st place.
RWD-2s were also used in several Polish air competitions and other minor international ones, with some success. They were also used for training in aero clubs. They were withdrawn in 1935 (one was bought by private owner and existed some longer).
