Yello, I run LOMAC 1.02 on Windows XP, everything works fine, except that some of the Russian aircraft (MiG, Su-33 and Su-27) tend to pitch upwards as if they had their own will, or as if the rudder was trimmed, I am still able to counter the effect with the joystick, but am unable to dive as fast as with the other aircraft.
I have tried recalibrating the joystick (my joystick is a "Logitech Extreme 3D Pro"), and reinstalling the game, both to no avail. This ONLY happens to the mentioned Russian aircraft mentioned, and everything works fine with the rest of the aircraft, I do, however, occasionally get the same problem with the German MiG.
Russian jets (and I include the German MiG in that category) need constant trimming. The western jets in Lockon do not. F-15 has auto trim and that is modelled in Lockon. I think A-10 ditto? or else it is because it is so slow you dont notice as much - LOL. I still love the A-10, even though it is a bit of a tortoise...
