Everybody knows that the n1k2 has a better rate of climb than the f4u4 right ? So why would we be surprised that employing vertical maneuvres against the n1k2 when flying the f4u4 does not work well ?
If you found yourself in a situation where you had blown your E so badly that you couldn't get away from the guns of a n1k2 in an f4u4 well all I can say is shame on you .
You know you can't out climb it, you know you can't out accelerate it, you know you sure as hell can't out stallfight it, so what the heck we're you doing ?
Without seeing the film all we can do is speculate .
