Well, the results are in:
A20 vs P51D - cobia
A20 vs P40N - cobia
A20 vs 109G6 - titan
A20 vs A6M3 - titan
A20 vs A6M5 - titan
A20 vs P38J - titan
Then we did A20 vs A20 twice, it was a tie (would've done more, but I had to log).
With the exception of the P40s and Zekes, I basically won by going vertical. The Zekes outclasses the A20 completely (as it should), though I was talking to cobia, and like I said before, he killed Zekes/Hurris by BnZing them but with an altitude advantage, in an equal E fight, Zeke wins hands down. The 51D fight was interesting. At first I was going vertical with him and although he couldn't get a shot on me, neither could I due to the crappy low speed handling. Once I started TnBing with cobia, the A20 won eventually after I used up all my E. 51D just kept snap stalling everytime I made a move under 100mph.
Cobia, fun fights all around.
As I said before, "almost any fighter can beat the A-20 if the fighter's pilot has some basic ACM skills and adequate situational awareness".
Of course, the Zero can out-fly the A-20. In a duel, that is readily apparent. In the MA, it's different as the A-20 can disengage and run from any Zero quite easily below 5k.
The way to beat the A-20 is to get the pilot to dump his flaps to maneuver. That's when you push the fight up hill. I'm sure you discovered that today.
P-40s, F4F-4, P-39D and the like can have a tough time because the A-20 is as fast or faster, climbs better and holds E better (again, inertia at work). Once the P-40 bleeds off his E, the A-20 then takes the fight up hill. The P-39Q is another beast altogether. It's as fast as the P-38J/L at 10k, and climbs very well in WEP.
Once more, the A-20 succeeds in the MA because, "a good A-20 stick will exploit any lackadaisical flying or lack of urgency. These guys do what they do because what they do is usually unexpected."
The A-20 relies on the other guy helping it to win... Poor flying, low skill level, lack of SA, etc... Yet, even in a 1v1 duel, the A-20 can be very surprising.
Since you've now dueled against and in the A-20, I imagine you now know how good A-20 sticks do so well. It's a pretty capable ride for a bomber and can take advantage of any lapse to kill opposing fighters.
Now, when I can get some time, perhaps you can meet me in the TA and we'll explore the A-20 further and the ridiculous low-speed maneuverability of the Boston.
