Hi Gutt!
I forgot to mention, it is also VERY important to set pilot head position for EACH view. How to do it? The 4 keyboard arrows(not those on num pad, the normal cursor arrows) control pilot's head position. Forward/Back, Left/Right and Page Up(head up)/Page Down(head down). f10 fixes head position for that specific view.
Try this. Press back on hat switch(and keep it pressed) so you get a back view. Than press Page UP until pilot head is at max up pos, now press f10 to fix view. Do this for each one of the separate views. Experiment!!!
After fixing all views to your taste go offline, choose a terget on the ground, a hangar for example, do some truns around it, but don't let it go off screen... When you're able to do that, you'll dogfight much better. "Loose the sight, loose the fight"...
As to the gunsight all you have to do is to train offline with different planes. Planes with nose guns will have different results than those with wing guns.
Watch your 6!!!
