Only 2 suggestions I can make on this:

1) use the AvHistory merlin sound from GregoryP. The stock Merlin is more Griffon like then the sweet sounds of a Merlin 

2) add a 'fake' insigina decal, as the roundels are painted on. Just choose a mesh (rudder/aileron or something NOT fuselage or wing). Using something like the statement below:

[Decalxxx]
MeshName=LeftAileron
DecalLevel=0
DecalFacing=bottom
FilenameFormat=Insignia
Position=-7.45,-0.10
Rotation=0.0
Scale=0.000001
DecalMaxLOD=1

That will activate the "Nation Name" service  on the Loadout Screen's dropdown.

Otherwise FANTASTIC JOB!!!! Big thumbs up!!

Nice-looking aircraft! The flight models are rather enthusiastic, though - the Mk 1 and 1b have been given 1730 hp engines, (should be 1030 hp), and the Mk2s have 1915 hp (should be 1175 hp).

With uber-Spitfires like this it is no wonder the Germans lost the Battle of Britain!

Feel free to restore the correct values in your files.
It was not done so in an enthusiastic mood. It was more constrained by the performance in flight and by the opponents from the downloads section (roaring in the skies of England like Me-262s).
So yes every engine has its power multiplied by 1.63 or something close and It's not an error. The endurance has been checked also with the fuel consumption of these overpowered engines.

Drag values have been checked from a study of the real aircraft. With the real engine power values you may have to lower them to reach the right top speed at the right altitude (in hard mode flying).

Interesting design concept, but it doesn't work. The zero lift drag coefficient for the Spitfire I was  0.0200, and for the Mk Vb was 0.0235. These Spitfires have total Cd0=0.0195, which is a little lower than reality, but close. The problem is that the airspeed at various altitudes is way too high. If you look at http://www.spitfireperformance.com/spitfire-I.html you will see that the Spitfire Mk I (with the original fixed pitch prop) could manage:

307 mph TAS (243 kts IAS) at 5,000 feet

328 mph TAS (237 kts IAS) at 10,00 feet

348 mph TAS (232 kts IAS) at 15,00 feet

360 mph TAS (223 kts IAS) at 20,00 feet

349 mph TAS (202 kts IAS) at 25,000 feet

The later variable pitch prop could manage a little faster than that, by a few mph (the numbers are bit lower down that web page).

I've just tested these new Spitfires, and with this extra and unhistorical (x1.63) engine power, they can do 20-30mph more than reality (264 kts IAS at 5,000 feet, 261 at 10,000, 254 at 15,000, 245 at 20,000, and 232 at 25,000, for the Mk I). In 1940 that was unattainable.

They are beautiful models,  but these are uber-Spitfires, and not realistic.

Gatling,
Perfectly understand your "issue", and I can tell you we had a very lengthy debate and discussion about the "power" of the engines. We used the spitperformance site also for information and whatever else we could scrape up on the net, and we had perfectly matching speed values according to available data. Only we run into one thing, we also wanted to make the handling characteristics as close we could, on most difficulty settings, which required seemingly more power. There are several ways to achieve them, but the shortest and easiest solution was to add that extra power. On the other hand, other currently released WW2 aircraft on the opposite side were/are mostly overpowered and was not "fun" to fight against them, when historically they should be on par with AC-s in this or upcoming packs. Since it is a game, we chose the fun factor more important than a couple of HP-s.

If you have the time and interest to make a perfected FM that solves every "issue" you may run into (power,speed,handling on normal and hard settings), you are welcome to do so. We work on the Spit family in our spare time we scrape from the other 4-5 projects we work on in parallel with this, so we welcome any helping hand that makes our work easier, faster or more realistic.

That is an interesting and well thought out design position, Logan4, I hope it works well in combat. I might increase the total of the zero lift drag coefficient a little (from total Cd0=0.0195 to 0.0200) and see how that works.

Great looking models, and thanks for posting them!

Love it! Thanks!!!

I wish they made a new cockpit according to the model
