When developing a new modification of the training machine, the operating experience of the Yak-7 UTI was taken into account. Yak-7V was developed in accordance with the installation - to produce faster and cheaper. This time the landing gear was made non-retractable. This was not something new; back in the summer of 1941, such changes were proposed by the head of the design bureau of plant No. 301 Cherenkov. The chassis niches were sewn up, but there were small hatches for inspecting the mounting of the racks. In order for the trainees to acquire the skill of retracting the chassis, a simulator of the lever for retracting and releasing them was installed in the cockpit. The armament was removed, which is actually surprising, given that a fighter pilot must be able not only to fly, but also to shoot.

Some devices were not installed in the cockpit, for example, the remote control was removed. The absence of a transparent partition between the cabins caused very great inconvenience. During the flight with the front light open, the instructor was mercilessly blown by the oncoming air flow, and it was necessary to fly with the light shifted, as the plexiglass, which quickly turned yellow and easily scratched, made it difficult to see.

Starting from the second series, some of the previously removed equipment was installed again, but until the end of the production of this modification, the partition between the cockpits of the cadet and the instructor was not installed.

During state tests (from February 18 to March 4, 1942) it turned out that the non-retractable landing gear practically did not reduce the performance of the machine and did not affect the aerobatics. The aircraft flew almost as fast as a fighter jet, and could be controlled from the front and rear cockpits.

The Yak-7V was mass-produced from March 1942 to December 1943. 510 examples were built, and another 87 converted from the Yak-7B. This is not much, given the huge number of pilots trained during the war. Almost every Soviet fighter pilot was trained on this machine.
