Bf109E-3

[Hunin]

Unfortunatly I don't have time to dig my teeth into this right now but here is the relevant ingame data.

Quick first impressions:

1. Cl max seems too low for both retracted and fully extended flaps.
Should be 1.4 and 1.9 according to british testing, 1.3 and 1.62 ingame atm.

2. Turn time of 25 seconds corresponds with british testing but is significantly higher then the 18. something stated in the official Baubeschreibung.

3. 460 km/h on the deck corresponds with both german testing of Wrk.Nr. 1792
and swiss testing. The Baubeschreibung on the other hand gives 500 km/h.
Any ideas where that difference might come from Kurfy?

Anyway here are the cold hard facts:
