Krasny and Ras;
TrackIR will improve your overall view, and situational awareness immense.
It will NOT improve your shooting skills. Shooting will rather get more difficult,
as your head moves now. But you can press "precision", that's like stiffening up your body and neck.
Now you can't check your six so quick anymore, but therefor aim and shoot more precise.
Your shooting skills must be developed. Forget the gunsights. Find out, were the tracers meet (when you have two guns) -
that's your "hit spot". Do some Quick Combat, and shoot at planes. When they come from right to left,
shoot somewere in front of them. The faster they fly, the more distance in front of them.
That is deflection shooting. It will sooner or later become a feeling. You will now feel, were to shoot.
That's when you've got it. Then, you can become an ace.
