Nhaaa, not alking about LW being specially hard, but there are planes a HELL OF ALOT harder then a Yak and P51. To mention a few allied rides, F4u, P47 D30 and such.
The Yak is THE uber ride except for guns, almost as fast as a 190 G10 at the deck, turns alot better, climbs great, no wep but it's so damn fast anyway. Can outscissor anything, a 190 doesn't stand a chance in scissoring.
P51D a bit harder to fly although you can run better in it.
