Thrust switch doesn't work on flightstick.

[moyrta]

Hello. I just bought a Thrustmaster T.flight hotas X flightstick and decided to try it out on IL-2 Sturmovik. But I ran into a problem. The game doesn't recognize the thrust switch, so I can't change speed with it. Tried to assign it manually in controls but no success. Please help. It worked fine in microsoft simulator X
I searched the forum but couldn't find anything about it, so sorry if it's a repost.
