The RWD 7 was a Polish sports plane of 1931, constructed by the RWD team.
Development
The RWD 7 was constructed by the RWD team of Stanisław Rogalski, Stanisław Wigura and Jerzy Drzewiecki in Warsaw. It was based upon their earlier designs, especially the RWD 2 and RWD 4. The RWD 7 was meant to be a record-beating plane, so it had a more powerful engine, while its mass was reduced. From its predecessors, it took the same fish-shaped fuselage without a direct view towards forward from the pilot's seat.
