It isnt so much about defeating the zeke that is harming you, but rather you not using the uber Spit16 to its best ability (or any plane) and not allowing the zeke to dictate the battle to you. I am no expert or top notch pilot, but one of the first things any pilot should do when facing an enemy is take a snapshot of the planes and they both (or more) can and cant do well. That is a bigger part of the battle than some will admit to, some guys even vouch for a %90-pilot/%10-plane which is BIGTIME BS. If that were true, we'd see far more SpitI/V, P40B/E, 109E/F, HurricaneI, and any other lesser used less-than-stellar aircraft in the game.
IMO... dont even try to go slow and low and turn with the A6Mx, not in anything. The A6Mx is king of the slowlowturn game. Even in a SpitI/V or Hurricane I/IIc or even another zeke, I will do my best to keep the battle going at angles and verticle. The zeke's best attribute is turning, it doesnt climb, extend, roll, or dive all that well. Remember that.
Oh... and I will also vouch for taking the HO if the zeke pilot challenges you to a game of chicken.
