So far I've seen nothing but great things in 1.39. Hats off to the devs, great patch! A lot of planes have gotten a lot better. Here is a few that I have tested so far: BF109 F4 - awesome! pure awesome! It moves, turns, stalls and heats up the way it should. P40E Kittyhawk - major major change. No more snap rolls. The plane can actually turn now. Now its a great match up for its tier and I cant wait to fly it vs the Germans. I got over 20 kills in it during the event by just BnZing and only died twice in 11 missions. Its not OP, they made it just right. A6M2 doesn't feel like the old A6M2, its climb rate has been reduced a little but the plane still performs well. Still turns like a beast. Since a lot of planes got a facelift, please post your feedback about what you have tested so far.
