Anyone else having a problem with the Yak-9UT, I am wondering why only 1 of the 20mm is firing, the 37mm works and the port side 20mm works but not the other one…I test flew other soviet planes with mixed armament and they all work fine, it is only the Yak-9UT…
hmmmm, maybe because it only has 1x 20mm gun when the 45mm cannon is equipped
make sure you set it to

vehicle modification current in test drive, otherwise you will always get the 45mm equipped with 1x20mm
