was changed to the more powerful 86 kW (115 hp) M-11G. The plane received the designation UT-1
, primary/advanced trainer); despite this designation, it was not suitable for primary training.
The UT-1 was used as a transitional type between the UT-2

. It was not easy to fly, requiring precise piloting, thus forming an ideal intermediate between basic trainers and the maneuverable but tricky to fly I-16. In 1939 the plane was modified by moving the engine 26 cm (10 in) forward, which improved its handling. During production, the 112 kW (150 hp) M-11E engine was also used.... Read More
