It was powered by two 140 hp Shvetsov M-11F radial engines driving two-bladed wooden propellers, with the engine installation based on Yakovlev's UT-2 primary training aircraft. In order to minimise the use of scarce resources, the aircraft's fuel tanks were made of chemical-impregnated plywood rather than metal or rubber.
The aircraft utilized two 140 hp Shvetsov M-11F radial engines with wooden propellers, built on the principles of Yakovlev's UT-2 primary trainer. To optimize resource utilization, its fuel tanks were constructed from treated plywood rather than conventional materials.
