As a general comment, it is not very analytical to determine that the plane-x is 'wrong' because it performs better/worse than plane-y. That line of thought doesn't take into account the fact that maybe the plane-y/both planes are 'wrong'.
Regarding the Typhoon/Tempest...
In a memorandum report on Typhoon, Americans reported the Typhoon's turn radius as "short".

Well, is it "short" in AH? Well, that is pretty hard to say isn't it.

In Mosq's turn radius testing Typhoon came 67th out of 103 AH fighters with a turn radius of 714,5ft. Mosq performed the turns as left hand turns. At right hand turns Typhoon would have most likely been more controllable due to its counter-clockwise turning prop and turning that way might have given a shorter radius.
Another general comment...
I'd like to see pyro doing a global review on some aspects of the flight model. Last major across-the-board flight model change was done in spring 2006 (version 2.07). A thing I'd like to see looked at is the lift/drag that the flaps cause in general. I really can't pin-point any particular planes, all I'm saying is that a fresh look is many times a good thing. I have no doubt that it would be a lot of work but I consider flight model to be the bread and butter of AH.
I remember pyro himself saying that he should 'weed out some inconsistencies' regarding the flight model after that 2006 2.07 update. No changes came after the 2.07 update, though.
