Wow! We've reached new heights in whining when you want the IL-2 penalized because you can't cope with a fat, slow climbing, poor turning tub....
The IL-2 pilot can't see diddly-squat to the rear. That's why they had a rear gunner, who would inform the pilot of what he couldn't see.
In terms of performance, the IL-2 is at the bottom of the heap. SBDs eat them for lunch.
