Hey guys, I'm trying to fly the Su-25T campaign. The only problem is that I can't take off without one of my engines catching fire (I use full throttle). I tried turning the autopilot on, but it just sits on the ground fiddling with the elevators. Can someone please tell me how to either take off in the Su-25T, or how to get the autopilot working? Thanks :)
