I don't know anything that's wrong with them, they're just fine. Probably the best at immediate turns, or going into turns, not very good at keeping it's E. However it the model best for jabo is the E, either that or the highly awkward N. For some reason for me though the P-40 doesn't seem very stable, it's too jerky for some reason. Everytime I try to get a bead on something I only make about 3/10 of the shot, due to trying to correct it. I think even the F4 Wildcat is a bit more steady honestly, but not as quick or anything else. However you go and try to shoot something with it and tweak it to be correct, it's very arduous.
