Hi Jab,
>Heinkel He-100 (German): Basically performs like a Bf-109G except without the 109's major flaws.
I would love to see the Heinkel He 100!
I'm afraid, though, it wouldn't really perform like a Me 109G: Remember it was powered by a DB601A, the same that powered the Me 109E.
The Heinkel figures for the type are extremely impressive - up to 16000 ft, equal to the P-51B. You'll admit probably admit that this sounds a bit too good for an aircraft powered by a 1175 HP engine :-)
Calculating back from peak horsepower of its special engine, even the record airframe in full race trim - reduced wingspan and everything - couldn't have reached the speeds Heinkel claimed for the combat-ready He 100D.
In fact, the record airframe might have equalled the Me 109G's speed at sea level, but above 16000 ft its performance probably was close to that of the Me 109F-4.
As an operational fighter with normal wingspan, full-height canopy, additional external radiator, guns etc., the He 100D probably would have been a good deal faster than the Me 109E-3, but not even competitive with the Me 109F-4.
Of course, the Heinkel He 100 would have benefitted from the development of the Daimler-Benz engines just like Me 109 did, so comparing it to later variants of the Me 109 isn't entirely fair, but nevertheless, it has to be recognized that the He 100 wasn't the leap forward Heinkel had hoped it to be.
Additional trivia for Heinkel fans: The He 100 plans, along with a production license, were sold to Japan where the Heinkel fighter became the foundation for the (highly modified) Kawasaki Ki-61 Hien.
