Here is what I am talking about. Compare the Huricane Mk I and Spitfire Mk I performancewise. Unlike later Spits and Hurris they have exactly the same engine.
The Spitfire Mk Vb and Hurricane Mk IIC have similar engines, so they are not a bad comparison.
The Bf109E-4 and Bf110C-4b have similar engines too.
That is why they are the ones I am talking about. A Huricane Mk anything at 17,000ft is going to be at a massive disadvantage against a P-51B or D or a Spitfire with a two stage supercharger such as a Mk VIII, IX, XIV or XVI because the Hurri only has a single stage engine, so pointing that out is irrelevant to my point.
My point is, that comparing the four aircraft in question when they were powered by identical or similar engines, as modeled in AH, the Spitfire and Bf109 do not come out matching the historical comments. And in fact the comments often seem completely backwards. Go fly a Hurricane Mk I and then a Spitfire Mk I, then try to sync your perceptions with the pilot comments about the Spitfire's responsiveness compared to the Hurricane's. They will seem to have gotten the names of the fighters reversed.
So, why would the Spitfire be delvoped with better engines than the Hurricane if the Hurricane was so superior to the Spitfire, only losing a bit of speed compared to the Spitfire? Why not put a Merlin 61 in a Hurricane? Why relegate it to ground attack?
Now, I am not suggesting AH model Hurricanes with engines they never had, I am expressing my skeptisim that either the Hurri was that responsive or that the Spit was that unresponsive.
Look at which fighter is the monster of EW? The Hurricane Mk IIC, which in reality was being channeled towards ground attack while the superior Spitfire Mk Vb was taking on the role of the RAF's premier fighter.
The Bf109E-v vs Bf110C-4b is a similar issue.
Furthermore, you started to discuss why the Hurri and 110 weren't slated for further developement, and the Spitfire and 109 were. Again, there are many factors' in that decision, other than A/C flight characteristics, that influence those choices(Engine availability, overall cost, tactical suitability, politics, etc.)
The Hurricane was cheaper than the Spitfire, used the same engine and was easier to build.
