History
It was probably Gribovsky's only biplane and was meant to compete with the Polikarpov U-2. It first flew in 1937 with a British Pobjoy Niagara II radial.
Variants
The G-25bis of 1938 used a water-cooled GAZ-Avia-11 with a radiator under the rear of the engine, which proved heavier and worse in performance.
Where you'll see it
It did not reach production, and flight trials ended in November 1938. Only one was built.
