That's very interesting and helpful! But also a little confusing.
I have a thrust up/down left/right hat switch on the throttle which "slides" the craft in those directions - essential for docking, also very useful when spinning around a platform looking for your docking pad. Do those controls behave differently with Flight Assist off? Can you do VIFFing in Elite? I normally never use those thrusters apart from takeoff/landing/cargo scooping.
With FA off, can I pull back on the stick to pitch up - not pull up, I'm learning! - so I do a 180 and end up flying backwards (and upside down) firing at someone chasing me?
I'm hoping the TrackIR helps too, since the scanner will tell you where the other guy is, but not really what he's doing. If I can look around to some degree and see if he's going left/right etc. then I could anticipate his move - rather than pointing my nose at him only to find he's no longer there.
It can be difficult to put into words. I'd say that pull up, pitch up is the same. I was clarifying the term "turning". In essence you roll until the scanner line of the target, is on the nose and then, pull towards the target. When you do this, usually there is very little surprise. When you pull to the target in this manner, when the scanner line (that represents the targets relative height above or below you) disappears, the target is guaranteed to slide into view on you nose, begging to be shot.
When pulling to the target, adding a thrust up or down input in addition to full back stick deflection, and varying throttle position will change angular rates of change. You just have to play with it.
For FA Off, I've read there are experts who have mastered it and hold the upper hand. I only use it in small doses and would fear having to fight another player PVP who had mastered it. But for my described techniques, it appears to be fine when fighting AI Pilots, even though at times they seem to flip their ships rapidly. Just remember that head-on passes are not always ideal.
My guess is that Track IR could help when fighting another ship accept maybe I don't have the right impression in one regard. When you are looking at a screen with a set fixed view, my understanding is that Track IR points your cursor at whateve you look at. But in ED you only point the cursor by virtue of where the ship is pointed and to see something over your shoulder you'd have to enable "free look". If Track IR can do this, then it might suffice except by virtue of turning your head, are you turning your eyes away from the screen? As I said, I don't know, but my impression is something like VR goggles like Oculus Rift might work better? Just wondering.
