I have similar problem. Randomly my video card crashes. The gamę goes black and comesback again but no anti aliasing is turned on. Im albo not Able to use mouse after this happens. Only keyboard works. I do overclock my card though but it's stable when testing with stress software and never have problems with any other game

I realise the rudder would have less effect at speeds,but don't you guys think it should work at all speed for coordinated turn. It seems the only way to turn the helicopter righ now is to roll it and pull on the cyclic.
