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! :rofl:

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.:pilotfly:

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.  :drinks:

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!  :good:

      Dear friends,
      Update 5.202 is live. It brings a lot of new content and improvements in different parts of the sim.
      The Battle of Normandy has been expanded to include 9 aircraft instead of the standard 8: Spitfire Mk.IXc, which we released today. As it was a mainstay of the RAF in early 1944, it is a great addition to the career mode during the Normandy period. This addition is retroactive, so all existing owners of Battle of Normandy will get this new bird for free.
      The second and last 'long' version of the IAR fighter, I.A.R. 80-B, is also included in this update, which means that IAR-80/81 is officially released. Owners will get two aircraft in the same purchase, the 'short' 80-A and the 'long' 80-B, each with its own set of historical modifications, including fighter/bomber ones, and paint schemes.
      In this update we also show some love to our older planes - our engineering team has thoroughly checked and improved the FM of several planes thanks to new historical data found by enthusiasts. P-47 critical AoA and maximum wing lift have been increased and made less stable (please be more careful with the flight stick until you get used to it). All Fw 190-A roll rates have been increased. The P-40 received the 1942 engine modification that allowed it to run on emergency power for a longer period thanks to reinforced ball bearings. WW1 aircraft shaking from damage is reduced and visible damage is tuned to better match actual damage. We were also able to add manual fuel gauges to more aircraft: all Il-2s, all Fw 190-A series, all He 111s, Ju 87, and I-16.
      These FM improvements are even more enjoyable because the control mapping process has been streamlined: not only can you search for an assigned command by pressing a button on your control device or entering the command name, but many new on/off commands have been added to assign them to HOTAS switches - parking brakes, engine superchargers, cockpit open/close, bomb bay doors, air brakes, Ju 87 siren, individual engine propeller feathering, etc.
      There are also many improvements to mission generation. Flying Circus pilots get their own Advanced Quick Mission Generator on the Western Front WWI map, which was previously only available on WWII maps. There are several improvements to the career mode: the flight altitude over the Western Front during WWII is higher than on the Eastern Front, 12-13,000 feet, and there is a new mission type, Airfield Defense (see other changes below). AI pilots should now generally do a better job of attacking head-on. The historical campaign Lightning Strikes has been heavily reworked and improved, and there are fixes for the Ten Days of Autumn and Steel Birds campaigns.
      New experimental mission editor features mentioned in our last DD are also in - to enable them, you can add the line full_editor = 1 to the [SYSTEM] part of the data\startup.cfg file. Changes you make to water and forest maps in the editor will be visible in the game in Mods On mode. The landscape change menu will also be accessible, but it's intended for enthusiast teams working on the new maps (a map with a changed landscape will not load in the game in Mods On mode and will cause an error during loading).
      All in all, we have done our best to include something nice for everyone in this update, and we hope you enjoy it!
      See you in the skies!
      5.202 Changelist
      The Romanian I.A.R.80/81 fighter is available in both variants (short and long) for all owners of the corresponding Collector Planes kit; British Spitfire Mk.IXc fighter is available for all owners of Battle of Normandy; Advanced Quick Mission mode has been added to the Western Front WWI map for owners of any Flying Circus module; A search by command name and assigned key/axis has been added to the control mapping settings; For easy assignment of HOTAS toggle switches, several cyclic commands are duplicated as separate on/off commands: bomb fuses, bomb bay doors, air brakes, Ju 87 siren, engine superchargers, canopy open/close, all propeller feathering, specific engine propeller feathering, tail wheel lock, and parking brakes; P-47: updated FM, reduced stability margin to better match historical data, increased maximum wing lift and critical angle of attack; P-40: added "Engine V-17190-39 (1942)" modification to reflect improvements in engine design that increased the allowable operating time at emergency modes; Fw-190 A-series: roll rate brought to historical values (increased); Fuel gauge switch control is implemented on all IL-2s, I-16, all Fw 190-A series, all He 111s and Ju-87; Career: the altitude of intercepting and escorting bombers in Rheinland and Normandy careers has been increased to 4000-4500 meters; Corrected the visual display of damage and reduced shaking when WWI airplanes are damaged; IAR 80/81: its unique bomb control system has been improved to better match the historical prototype - in the bomb drop mode the bombs are released by the main trigger (command "fire all guns"); Career: updated Airfield Defense mission; Career: Spitfire Mk.XIV fighters in Rheinland career are equipped with E-wing (two 12.7mm instead of four 7.7mm machine guns); Fixed a problem with AI pilots pulling away from a frontal attack too early; Improved routine for detecting an enemy attacking a group of AI planes from blind spots; Fixed a problem with AI gunners aiming in tanks with coaxial machine guns; Experimental features for editing water and forest maps have been added to the editor: to enable them you can add the line full_editor = 1 to the [SYSTEM] part of the data\startup.cfg file. Water and forest map changes you make in the editor will be visible in the game in Mods On mode. The landscape change menu will be also accessible, but it is intended for enthusiast teams who are working on the new maps (an existing map with an altered landscape won't load in the game in Mods On mode and will result in an error during loading). Career: in the transport escort missions for the Eastern Front career, the front line has been restored; Career: fighter-bombers have been added as targets in the Attack Intercept and Attack Escort missions; Career: Fixed rocket launches in the air without gaining the right altitude in Assault Escort missions; Career: fixed very long attack of a target by attacking aircraft on the runway for Attack Escort missions with start on the runway; Career: for Transport Escort missions for Eastern Front careers, fixed smoke hanging in the air that should be on the ground; Career: redesigned the template for escorting transports that bring cargo to the airfield instead of dropping it on parachute containers, fixed a bug with escorted transports not being able to land; Career: Fixed early scoring of mission success when the plane has not even reached its airfield yet; Career: Fixed takeoff at Malye Chapurniki airfield on Stalingrad map; Career: Added a new engine for AI P-40 fighters in Stalingrad and Kuban careers; Western Front" map: fixed takeoff at Braizieux airfield; Updated "Lightning Strikes" campaign; Added sound for all La and LaGG on the release of the bomb drop button; On La-5F and La-5FN, changed the limitation of camera downward movement when the canopy is open; IAR 80/81: Bomb racks removed from fighter modifications; Fw-190 (all): corrected animation of cockpit canopy opening handle; Ju 88 C-6: fixed a bug displaying one of the bombs in the bomb bay; Several popular multiplayer servers have their icons in the server list (please contact our Community Manager if you want to assign one to your server); Small fixes have been made to the "10 Days of Autumn" and "Steel Birds" campaigns; Improved air behavior of parachute containers and Ar 234 rocket boosters; Fixed a problem with artillery gun crews when repairing them by MCU Command: Damage.

      Dear friends,
      The beta testing of the new update 5.202 continues: IAR-80B and Spitfire IXc are being polished and new career changes are being tested. The new control assignment features are working great.
      We have some good news about the upcoming Spitfire IXc: this aircraft, which was a mainstay of the RAF in early 1944, will be added to the Battle of Normandy lineup. This means that all Battle of Normandy owners will automatically receive it when the 5.202 update is released. This will make the BoN career mode even better and more realistic. It also means that both Western Front modules, Battle of Normandy and Bodenplatte, will have their own Spitfire IX, which was an iconic British aircraft of the time (there is a Spitfire IXe in the Bodenplatte module).


      In addition to the new content and improvements in nearly every system of the sim mentioned in our previous DD, 5.202 will bring a neat feature that many of the Mission Editor enthusiasts have been dreaming of - on-the-fly editing of landscape, forest, and water maps that previously could only be edited using 3rd party graphics editing software.
      This feature, developed by our lead programmer Sergey, makes editing much more intuitive and easy as you can see the effect of your changes in the sim world immediately - you can plant a forest or cut down the trees near the airfield, fill a new river or remove a lake, create a mountain or dig a ravine. Here are some preview screenshots of this feature.



      The new version should be ready for the release soon, in two weeks 
    • By 76.IAP-Blackbird
      Dear Friends,
      We are preparing the next update 5.202. It will bring the second, long version of the IAR-80 and the official release of both variants. The fire control system of the IAR has been corrected to reflect its peculiarity - the bombs are released by a firing trigger when the bomb control system is switched on.



      Another new aircraft we plan to release in this update is the Spitfire IXc, which will be a welcome addition to both the Normandy and Rhineland careers of the Western Front.



      This version will also feature other improvements across the board - some of them were requested by the community for quite some time and we finally have had the time to do them. Here are some notable points.
      AI pilots will be more aggressive in frontal attacks and will break off later. Bombers in the Western Front career mode will operate at higher altitudes than on the Eastern Front, 4-4.5 km. A new mission type will be added where you'll have to defend a friendly airfield from an enemy air raid. There are also a number of smaller fixes to various Career mode mission types. 
      Quite a bit of improvements are being added to the input subsystem: most importantly, it will be possible to search for a command assigned to a button by pressing it or moving a control axis or search for a command by its name. To make mapping a HOTAS controller easier, several command bindings were duplicated as separate on/off or open/close pairs: bomb fuses, bomb doors, air brakes, Ju-87 siren, canopy, prop feathering (all, 1st engine, 2nd engine).
      As you may already know from our Q&A video, our engineers are working on updating the P-47 FM using the newly found data kindly shared by community members - we can't promise it will be ready for this update, but we're trying. The P-40 FM review is also in progress.
      In other news - our Steam prices now are regional, the price in each region or currency is suggested by Valve (this means that they became lower in most parts of the world, however, due to the currency value changes there are countries where the modules which were released several years ago became a bit more costly or stayed the same).
      The update 5.202 is planned to be released in the first half of February.
