Flathat,
The Bf 109G-10 was a messer one step away from the Koenig
Add that methanol-water concoction and you have a LW plane that is quite formidable, and fast. An excellent vertical-dogfighter. It is, unfortunately, a very misunderstood plane, since it does not handle well in the traditional, full-throttle, BnZ role. Keep the throttle low on the dive, though, letting the plane climb by its wings, and you have a fighter that turns BnZ into a tight, surgically-precise technique
