In 1944, the Russian government wanted to build a plane that could counter the German Me 262 or any other jet fighters had the war gone on that long.
In 1945 when the war ended, this plane began construction and the armament was supposed to be two 12.7mm machine guns and one 27mm autocannon. Though, the cold war had begun and the Soviets thought they would most likely face the United States first, so they switched the armament to 3 20mm autocannons to take down B-29s.
Powered by 1 piston-powered engine and turbojet, it was quite fast as a mixed-propulsion aircraft.
This plane was originally supposed to be mass produced as a very simple plane (the only electronics on board were a Radio and a gun sight), however, problems at the factory caused the program to shut down after only 13 were made in 1946.
This plane can fly at up to speeds of 530 mph and it has a decent punch with the three 20mm autocannons (of which I coded to work like the real ones did). Sorry its part count is so low, but it looks quite good for it. After you pull up landing gear, the plane starts slowly pitching up, so put trim in between the middle and the first bar going up to go level flight.

Weapons:

No pilons were added to any of the planes, so the only weapons were the three 20mm Berezin autocannons.

Controls:

Normal plane controls

I hope y'all enjoy!
