Need your opinion about IL2 planes

[IceFire]

CWMV has some good recommendations. The Mustang is not a beginners plane anywhere. It's a top performer to be sure but that comes with some prices and that makes it less forgiving.

The Spitfire is definitely easier but the Bf109 in many models (especially the F and early G series) are by far the highest performing aircraft in IL-2 while simultaneously being fairly easy to fly.

I'd add two more aircraft to the list of fairly easy to get started but requiring some serious work to master. The F4F Wildcat (also the FM-2 which is a later model) and the Hurricane. Both have fairly benign stalls but they are serious enough to teach you what not to do. They are both slower meaning you'll have to learn how to keep your speed but they aren't so slow as to be boring.
