If i get bored i start flying through tunnels or do hard turns between high buildings. That changes the situation, because the guys behind you cant follow and it's easy to get behind him then. And if you are once behind him and shoot, it's almost impossble for him to escape.
Yeah this is true: in the first Rustler event, the last duel was between Gz0r and me, which starts at minute 4:00 of this video:

That was what really made that fight so exciting. You need skills not only to make sharp turns without losing too much speed and altittude, but also to follow the other plane through such routes without crashing, and without losing too much time either, because otherwise he could have got himself behind me. And as Qwerbeet says, if in a Rustler combat you have the other behind you, it's almost impossible to escape.
That's why the key of Rustler combats is getting behind the other player.
