It was constructed by the RWD team of Stanislaw Rogalski , Stanislaw Wigura and Jerzy Drzewiecki in the DWL workshops (their designs were named RWD after their initial letters). The new plane differed from previous RWD designs, having a cab with two seats next to each other, folding wings and good wing mechanization ( slats and flaps ). Development

6. Only 3 aircraft were built, the first one was flown on June 3 , 1932 by its designer Jerzy Drzewiecki. The aircraft were given civilian registrations SP-AHL, SP-AHM and SP-AHN. During trials, SP-AHM crashed and J. Drzewiecki was hurt. After some modification of tails, two remaining RWD-6s were sent to the Challenge contest. Challenge 1932 , held between August 11 - 28 , 1932, was eventually won by Franciszek Zwirko (pilot) and Stanislaw Wigura (mechanic) in their RWD-6 SP-AHN, with a start number O6. The other RWD-6, flown by Tadeusz Karpinski, took ninth place out of 43 competitors (SP-AHL, nr. O4). During contest, the RWD-6 was given the highest note for technical evaluation of all participating aircraft.

7. On September 11 , 1932, the RWD-6 SP-AHN with Franciszek Zwirko and Stanislaw Wigura aboard crashed during a storm, flying to an air meeting in Czechoslovakia, and both died. The cause was found to be too weak wing mounting, that caused wing warping at higher speeds. The last remaining RWD-6 (SP-AHL) was modified after this accident, receiving a strengthened wing and the new designation RWD-6bis . The RWD-6bis was completed and flown in September 1933. In 1935 it was broken up, and its fuselage was used to create the RWD-13 touring plane prototype. A direct development of the RWD-6 as a sport plane was the RWD-9 , a winner of the Challenge 1934 .
