Urchin, it really all boils down to the pilot. A spit V SHOULD win vs. a N1K2-J.
The Spitfire holds it's Energy sooooo well that you can use that against it. Which is why I chop throttle (reverse rudder sometimes) and bleed my E so fast when it's clear we gonna knife fight.
IF the Spit pilot knows what's what and are also bleeding Energy, it's gonna get "interesting". Of all the Spitfires, the V is the one that gives me the most "concern" when fighting when I am in a N1K2-J.
(turn rate comparisons. values are No Flaps, One notch, and Full)
N1K2-J (0.05)
- 17 seconds (167mph), 202.0m
- 16 seconds (153mph), 174.2m
- 15 seconds (134mph), 143.0m
Spitfire Mk.V (0.05)
- 16 seconds (138mph), 157.0m
- N/A
- 17 seconds (102mph), 123,2m
If you look, the V turns best w/o flaps @ 138mph and w/ flaps 102 mph. The KEY to beating it in a N1K2-J is to be already in position when those speeds are reached, or well on your way at least. When fighting a Spit V that 170-220mph window, like I said, is key to getting yourself IN position.
IF you are poppin' out flaps like crazy you can have the N1K2-J's flaps full down before the spit can drop theirs giving you a small window to get position on it. The N1K2-J with two notches of flaps can turn with a Spit V not using flaps. Three notches and you will out turn it.
IF the Spit V manages to get their flaps out and you are NOT in position, you in for a rough fight.
