I have to say, Soda's evaluation is just plain wrong.
With a top speed of barely over 300mph, it's never going to be a great BnZer. It's got a light ammo load, and fast firing guns, meaning you get in close for a kill.
It's a great manuvering plane. Mix it up. There are only 2 problems with this:
1) It can pull wonderful moves as long as it still has some E, but once it's below the 150mph range, it won't regain that E quickly and the manuvers will start turning to mush.
2) the great range means heavy fuel tanks in the wings... When dogfighting light (50% fuel or less) it's very light on the controls, like a tubby A6M, but if you get bounced or forced to dogfight when your tanks are closer to 75% or 100% full, you REALLY have to be careful about how hard you pull her around. Seriously, you have to be gentle on the stick and (i'll use the first example that comes to mind) fly it like a Pony. The heavy fuel leads to the onset of "mushy manuvers" at higher speeds, bleeding E all that much faster.
Both of these leave you totally at the mercy of any other cons that dive down on you when you're saddling your primary target. I've personally mixed it up low and slow with a number of US planes in a Ki61. A P-47 fight comes to mind: I was on the deck against a jug and we were both using flaps and rolling scissors, and for 5 minutes the jug's super flaps kept it alive, but in the end I got the kill. It's a lovely plane. It has killed many a spitfire because it'll turn very hard at higher speeds, bleeding the E out and thus shortening the turn and cutting in behind a target for a nice 1-burst kill. The downside: Once it's bled out all its E in manuvers like this, it can't disengage and it's on the defensive. Pull hard in turns as needed, but leave yourself a bit of an "E" reserve.
