Throwing some light on rates of turn

We therefore just learn that the 109 was a good turner (perhaps better than ingame but that's another discussion) and better turner than the P51. Now that is nothing new at all.

Fun to watch but not even anecdotical evidence on how close the Spit and the 109 were.
