I have several:
109 Emil (Ive started liking the Emil more than the others, but i love any 109)
Me 262 (Never got to fly one yet. I know ill suck at it, but i still love her!)
La5 (My best plane. I am a biatch with an La5, but almost never fly one!)
In real life... Same thing. But instead of the La5, that little russian... Il 6, or I 16... i dont remember exactly what its called, but it was one of the first ever mono-wings, and late in the war they stuck a ram-jet in its tail!
