While not a fan of stick stirring, the only defensive maneuver I really dislike is the sudden disappearance of a plane that is growing larger in my gunsight which magically reappears behind me in perfect firing position. How does that happen?
Its the lag roll man. When an enemy is chasing you , you go in a nose down turn. Most of the time they will follow you. Since you are going slower and are in a better angle turn than the enemy, you have the opportunity to either A. Get them to black out for a split second, B. Get them to make a incredibly hard lead shot allowing them to have to aim higher while losing site of you. At the perfect timing you lift up cut a bit of throttle and do a reverse roll ( in the opposite way of the nose down turn) and you can roll over their plane. If the enemy is unsuspecting, while they were blacked out or leading you they completely lost site of you as you do the roll over. And you gain a nice spot right on their 6. Best move in the game. Takes practice though!
PS. Its very important to learn ACM. You will always gain the lead on some chump who is trying to HO you, you become a much better overall stick in the MA causing you to get more kills and lands, you can manage your and others E much better, and you have a better chance at getting away from or killing BnZers, and your level of game play will improve. I think ACM is the most important technical aspect of the game. And you can use these maneuvers in every single plane.
