Completely agree with the OP.
I fly a IIa all the time and in the latest beta patch its gone horrible! my max speed now is only 240MPH which is just way off real life stats..
Also, i keep cooking the engine which never used to happen at all! this is even with a fully open radiator!
maybe i could live with the heating issue, but when my plane cant even catch up a bunch of bombers is where i draw the line:
If anyone is interested here are the real life stats of the IIa:

Also those arguing about 109 vs spitfire, i found a good documentary on the 2:
