Lets get something straight right now! First of all the trainers in the TA don't train. Sure they can tell me what key to hit for range or squad channel, what planes are the fastest or best turners..etc. But ask them about some advanced fighter tactics with a 38 or something along those lines and all I get is.....ah...well... you need to talk to so in so about that...
Sigh.
The principles of ACM are the same for all planes. If you're looking for some magic trick in plane A, you won't find it. Understanding the strengths and limits of a plane, and flying it to its limit
smoothly, correctly anticipating where you need to fly toward, is not something everyone is able to do at the same level.
Some people are simply smoother, anticipate better or are quicker than others. Some people are more disciplined about practicing the things they are not good at, instead of practicing the things they are good at. What I mean is that in golf, some people will hit 7 irons at the practice range because it's their favorite club. They watch the trajectory and get lulled into thinking that they are "good" because they can hit one club well from a perfect lie, but don't understand why they can't break 90 on the course.
They should be practicing the clubs, lies and shots they are not good at.
Understanding energy and angles comes from reading and comprehending the principles, then applying them. I can tell you over and over to put your lift vector toward the bandit, but if you can't figure out the hand-eye coordination to make that happen, what can I do? Just like the golf analogy, I can give you tips and lesson after lesson, but that doesn't mean you will ever be able to break par in your life. Not everyone is same. If they were, everyone would be under par, and all 1 v1 fights would end up as a stalemate. Ironically, most fights against similar level of players are stalemates until one makes a slight mistake.
It's the mistakes, not any tips, that make the difference.
