Kalinin K-9
The Kalinin K-9 was a liaison/sport aircraft designed by Konstantin Alekseevič Kalinin. It had a parasol wing, only one was built in 1932. The prototype was evaluated during some test flights, but development was never carried out. The tests revealed that in fact the K-9 was too large and too heavy in relation to the installed engine, a radial Walter NZ 60 of 60 hp (44 kW, 12.8 kg per hp).[1]
