Just an opinion, but if this is realistic, then il-2, CFS3, and all MS FS single engine payware addons are child's toys!
Any opinion or suggestion on techniques on this guys? Thanks.
Well you could say they are
As Buddye says, you have to apply power very gradually until the airflow starts and things lighten up. Do it very slowly and 'feel' the aircraft. It's easier in the Hurricane. As an experienced BoBII simmer you can accelerate rapidly even in a Spit but you will be naturally (and subconsciously) dancing across ailerons and rudder as the speed increases- something you absolutely will not do initially. There's a reason it took 15 hours practice before you were even allowed near a 1000HP monster.
Landing is equally brutal unless you do it properly. Don't even attempt it above 70-75mph. If you can't fly at that speed it's not the aircraft's fault- you have not worked flaps, trim and prop pitch properly.
Of course you could try a 'sim' where these things don't matter. But then they do in the real thing.
