I have very good success in EW planes in LW arena. But that's rarely result of a "fair fight", particularly not 1v1. Even a player of average skill can at least deny me the kill in such a situation, using the speed of his plane to control the situation, even if he can't kill me. You do not need much skill for that, only some common sense. In 1v1 situations I generally only kill those really dumb enough to fight me on MY terms (P-51 trying to flat turn with my Hurri I for example)
The majority of my kills though, comes from creating and exploiting very advantageous situations.
Those type plots more often then not know their plane but not their opponents. And you can read all you want about the other planes but without having flown one yourself you never get a true feel for what it can and cant do well or what its capable of. Such is the case with your pony Vs hurricane. I bet lot of those guys read the history books and watch TV where they tell what a superduper plane the pony was, or the spit or any of the other ezmode planes. Then they come here and fly only those planes because they are the easiest to fly and they have this uber rep and get their butts handed to them by "lessor" planes.
Couple main reasons for this is. unlike you or I,they never bother to take the time to learn the other planes very well, if at all. So they think well on the history channel they said this plane can do this or that and that or this very well. Then they come up against someone like you who not only knows what your plane can do. But what their plane can do as well. Then you just use your experience using your strengths against their weaknesses and are patient enough to goad them into fighting your fight. They loose patience with their standard tactics give up their advantage in the effort to get a quick kill and decide to fight your fight. End result. They get their butts handed to them.
If your smart you learn how to get kills using every, or as many different planes in the game as you can. Then when you go up against a P51 with a Hurricane. You know how to play them to your advantage
