They would move to fly Typhoon, because it is very much same kind of plane, but does not turn good when slow (unlike F4u, which I wonder because it was said to be bad turning plane when slow...)
What other Tiffie has to offer?
It has also 2x2000lb bombs and even more rockets, though, not usable same time and no drop tanks.
but whats most fun in Tiffie is its 4 hispanos of course!
some of them would turn to fly N1K2, that does not care about ground targets that much.
Because F4u probably can defend itself with its miraculous slow speed turn better than Tiffie, it would probably mean that tankers would have bit easier times.
and we DO know that f4u C and Tiffie are only planes that can strafe tanks like bunch of fleas. (zzz.. one of these boring issues)
Of course allies would then give up a big whine and axis wouldn't have anything to say to it. (we know why this too.. and we know why this is not going to happen anyway)
But I think that f4u C should be at least some level perk plane, from the lowest requiring end, because what I know, D was that F4u which was mainly used.
