the 205 was a completly different airplane than the 109F.
Well, I am an engineer by trade, not a historian, so I admitedly, don't know much about the Regia Aeronautica flying styles.

However, for a simplistic comparison (the most you can do with commonly available reference sources), the four most defining attributes of an aircraft are its
Max Speed, Climbrate, Turning Ability (estimated by WingLoading), and its
Acceleration (estimated by Powerloading).
Here is the appropriate data for these two aircraft.
C.205 Me109F
Max Speed(mph) 399 388
Climb to 10k 150 137
(secs)
WingLoading 30.66 30.46
(lbs/sq.ft)
I don't have any figures handy here at work for Powerloading, but otherwise the C.205 and the Me-109F compare very closely.
The Veltro is slightly faster than the Me-109F, but is slightly slower to it in climbrate to 10,000 ft (I would guess its more aerodynamic, but has a less efficent wing design in regards to climbing). The wingloading is almost identical, and since they use the same engine with the same approximate airframe size, I would guess that the powerloading is also pretty close.
In fact of the entire planeset of both AW and WB, and you want to pick an aircraft that most closely matches the C.205 for a simple comparison.... guess what.... the Me-109F.
I have a complete writeup of data and estimated abilities, of the C.202 and C.205 Fighters on my website, in the Plane Archive section. There are also several nice Macchi Pics there as well.
Of course, there is also Lethality, but that doesn't effect how the aircraft will fly. Just for those that don't know the C.205 was most typically armed with x2 12.7mm MG's(cowl mounted) and x2 7.7mm MG's (wing mounted). It could also carry up to two bombs for a total weight of 750lbs.
So personally I would consider it lightly armed for mid-war aircraft, and very lightly armed compared to late war aircraft.
Now, I am sure a real AeroSpace Engineer, could do a better job than poor little me

(Electrical&Computers), but the basic principals I believe are sound.
Guys, please realize that I am not trying to slander the C.205, I was only trying to compare it to an aircraft that most of the other pilots here would be familiar with.
So Congrats on getting an Italian Fighter
