MR-5, R-5A, "10" by N.N.Polikarpov, D.A.Mikhailov and V.B.Shavrov

Naval reconnaissater, quite straightforward conversion of the R-5 into floatplane. Wooden floats used same technology as Shavrov's Sh-2 flying boat.
The only modifications to the aircraft itself included doubled tailfin area and manual starter on the side of fuselage nose section. Traditional way to start engine by turning a propeller is quite complicated to perform staying on the water surface...
Flying characteristics were quite good for floatplane, despite it was 389kg heavier.
First MR-5 was built by TsKB in 1931.
Series production followed.
