The P40 has never been able to compete against a well flown BF 109 F in this sim.
NEVER.
It still cannot. It is slow in the climb and does not have the power for sustained low speed turning, even though it is a good turner, for a short while anyway. It does have a good rate of roll, which is historically correct, and it is good in the dive, which again is historically accurate.
It has a stout airframe, which again the real aircraft had.
It has a glass jaw engine which is not in line with the historical record.
Sorry if you don't like the AP loadout for the M2 Browning, but hey, that's what the USAAF typically loaded, so again historically accurate. If you think that six of them hitting in convergance won't hurt then you have no clue sir.
And if you doubt the effectiveness of the P40 than I suggest you do some research into the 325th. Fighter Squadron, USAAF, "The Checkertail Clan".
Nearmiss, the Merlin engined P40s were really little better than the Allison engined ones, as they did not have the two stage supercharger like the Spitfire and later, the P51 had.
