Ya the Emil report was from BoB timeframe (love how it surmised that the 109 was inferior to the spitfire and hurricane!) but subsequent testing of F's and G's gave similar results. I kinda take these with a grain of salt, because it was during a time of war and the british eval of the 109 definitely made me think that there was a bit of nationalism involved (109 overall inferior to the hurricane...right) but we don't really have anything else to go off of unless the current owners of restored 109's are willing to do these tests. I have no doubt that the problem was imporved upon, but I find it very hard to believe that the problem was ever 100% fixed and the 109 could pull out of a 500MPH dive with ease.
Said about a 109F by the british, that the elevator control was better than the E, but:
"As a result of the heaviness of the elevators at speeds over 400 m.p.h., violent evasion is
not possible, and the aircraft would present a simple target to a following
Spitfire."
I too prefer the last UP FM for the 109's. These in HSFX5 perform really well I just wonder if it inst too much. Fighting spitfires shouldn't be an easy no question win, although AI has alot to do with that.
