History
The prototype was completed in the autumn of 1936, with flight trials commencing shortly after, on wheels and skis. It used a fuselage of Enerzh-6 stainless steel built-up truss covered with Delta-wood, and an all-wood wing.
Variants
A single prototype was built, powered by one M-100A engine of about 840 to 860 hp.
Where you'll see it
About 300 flight tests gave promising results, but the aircraft was expensive to build and run, so no production was authorised.
