I was trying to make some plane, but for that i needed invert the propeller. I saw that I need press F so i did it and nothing happened. Than I tryed change in controls button for inverthing but in game it still didnt work and in down bar it still shown me to press F even if i changed button for it. I tryed to restard the game even reinstal the game and it stil didnt work. So please fix it or ill have to press F to hold respect to my plane, get it?
