soo there were FBW prior to F18 module yes or not? ... you should fly more simulators and more years before making assumptions.

in game the K4 radiator flaps work perfectly synchronized in both wings, but in real live the Bf-109G hydraulic actuators of the radiator flaps have a little bit opening retard, comparing one wing, with the other. this cause a roll movements when open and close automatically. Volker Bau explained that he open the radiator flaps in manual mode because the unexpected automatic aperture of the flaps on take-off run could cause a unwanted bank in the worst time. As far i know, In the full open and full close positions of the both wings radiator flaps they don't affect to trim of the aircraft. null

That wouldn't happen if you were flying with the correct neutral trim ( aircraft leveled, straight, ball centered at cruise speed, hands-off and zero degrees trim position), because you would have the control stick in the center and whole stick travel for pulling all G´s that you want. Even you could trim -1º (nose-up) prior to engage in a dogfight like did Lt. Kurt Bühligen (112 victories) flying the Bf-109 G6. As we can read in the book P-47 vs BF-109G/K by Martin Bowman.

As far i know DCSW is a E.D. development of the LOMAC released in 2003 with Su-25, Su-27, Su-33, Mig-29A, Mig-29C, F-15C, and A-10A some of them with computer aid for flight controls.

After 20 years working as aircraft mechanic, and with more than 25 hours fliying as pilot student, i think that probably we could have the same trim configuration problem in all warbirds modelled in DCS due to two basic things. 1/ Trimmers of an aircraft are not an exact science. Wind direction , speed, air density, etc change the aircraft behavior in same level flight condition in the real world.. Even the real pilots don't pay great attention to trimmers indicators because in flight they usually trimming the aircraft by feeling or flight attitude. But trim position must be checked in T.O. and landing checklists. 2/ the weight and balance and CoG position of the aircraft change if we change the load of the aircraft, via fuel consumption, dropping bombs, etc As we are doing in the real planes, the developers should model the neutral trim position for cruise flight with "typical" fuel and ammunition load. But after that the cruise flight trim position in the cockpit, will NOT be the same with the aircraft in full weapons and fuel load. Finally i'm not sure if developers of DCS are doing this in the Flight Models. As you must know DCS born for modern jet combat simulation, and many of these modern jet fighters have fly-by-wire control computers who trimming the aircraft automatically for a take off weight, .. so manual neutral trim was not needed, as we need today with DCS WWII aircrafts. This mean that many virtual pilots accustomed to jet fighters auto-trim, will feel rare behavior of the warbirds if the neutral trim is not properly modelled, for a typical take off weight and cruise speed.

@Art-J and @motoadve I think that we cleared what was the true stabilizer trim configuration of the Bf-109G in cruise flight, in our interview to Flugmuseum Messerschmitt test pilot Volker Bau in 2016. The neutral trim modeling of the K4 in game is completely broken compared what Volker Bau said. ..and yes it is awesome, but it still broken from 2015.

Spitfire’s had Hispano cannons jamming problem too in tight turns. Merlin’s cylinders heads had several overheat and leaks problems in several types what affected to P-51 too. TheSpitfire’s high pressure cooling system cause radiators explosions when they take a bullet hit, leaking all liquid in seconds, … could we have this in game too…? Even overboosted Merlín’s with 130 and 150 oc. Fuels burned the sparking plugs in less than 8 hours of flight causing pistons boring destroying the engine. Do you like these failures in game too.?. … please, read the book “the secret house power race” by Calum Douglas prior to write these silly things.

By the way Full nose down in a real Bf-109k4 was +1º 10”. (Positive numbers). In game the trim gauge in the K4 show +2º in full nose down trim position. The stab. trim in this airplane is a very old and very know bug.

The Meteor's had serious problem of cannons jamming and others engine and controls problems , when first 6 were released for service, it was main reason because Meteor were not operational for combat until end of the war in 1945. Would you like a Meteor modelled with these problems here?

As far as I know, shelf sealing tanks were not capable to stop leak caused by 20 mm shells, even German mine shells could blow off a fuel tank with a single hit. by the way, remember that only 5 hits of German 30 mm mine shells (used by Bf-109K4 Mk-108 motor-cannon) were enough to down a B-17 or B-24, I.a.w. wartime German test reports, and guncams films. Radiator in a Polikarpov i-16 ?? … As far as I know i-16 had air cooling radial engine, it had not water or liquid radiators, … oil cooler perhaps?.

i don't have VR headset yet, but according with 3 of my squad mates who are using VR headset from months ago. if you have the VR pov settings propertly centered in the cockpit, you must see the optical sight only centered with the right eye, as it was in the real Bf-109.and you must be able to aiming with the right eye in the lateral emergency iron sight too.

I am here again to congratulate you on how your server has evolved in the last few days. the last tuesday i've gratifully amazed when i could enter in the 4YA-Overlord server with 100 virtual pilots on-line. I had not seen that large pilots meeting in a server from old times of iL2-46 or iL2-CloD.. i had never seen this in DCS WWII servers. unfortunately, i was forced to uninstalling SRS because is not comfortable to talk with SRS in server comms and Discord with my squad mates at same time even in different languages, but text chat worked propertly in the server when it was needed. By the way, i would suggest that the adding of the friendly units icons in F10 map, could be a good help for find and help teammates in the server, without sustancial lost of historical accuracy. this is a video of my sortie. i hope that you like it .

Your reclaim is nothing new in this forum. There are dozens of post referring to rare behavior of the FM of K4 in game such as; neutral trim broken (zero degrees position cause pitching up), lack of elevator autorithy for climb or dive (depending in joystick command curves settings), lateral instability in roll axis (even with throttel off or engine off, gliding), etc. all of these opinions were understimated or discredit. Some of us even have interviewed to a real Bf-109 pilot about the behavior of the real airplane trimmed for cruise flight, but it was not a valid evidence for E.D. developers team. The main problem is that there is none airworthy Bf-109K4, we need that Arsenal-45 company finnish his project to built new one. .. even in that case, i have not hope that E.D's team would take its flight characteristics as valid evidence to change the FM of the K4 in game.

Entschuldigung, wenn ich nicht richtig schreibe, mein Deutsch ist sehr einfach. Die Tatsache, dass das Flugzeug einen größeren Höhentrimmungs-Einstellweg in Richtung negativ (hecklastig) und weniger Weg in Richtung positiv (naselastig) hat, bedeutet, dass das Flugzeug konstruktionsbedingt kopflastig ist. Soweit ich weiß, hatte die Me-109 trimmklappen auf allen Flugsteuerflächen. Diese Trimmklappen wurden in eine Position geklappt, um einen Horizontalflug (ohne Hände) bei Reisegeschwindigkeit mit der Höhentrimmung in der Nullposition zu ermöglichen. (mit Standard-Startgewicht, ohne externe Lasten usw.) Auf Seite 102 des K4 DCS-Handbuchs in englischer Sprache wird erwähnt, dass die normale Position der Höheneinstellung NULL ist, aber im Spiel brauchen wir in dieser Position viel Druck auf den Joystick, um die Nase des Flugzeugs ausgerichtet zu halten der Horizont. Auf Seite 111 desselben Handbuchs wird erwähnt, dass das Absenken der Landeklappen das Flugzeug nase schwerer macht, aber im Spiel ist dieser Effekt kaum wahrnehmbar. Dass in den speziellen Einstellungen des Spiels für dieses Flugzeug auf die Verstellung der Ausgleichsplatten zur Höhenverstellung verzichtet wurde, lässt auf ein besonderes Interesse daran schließen, dass dieses Flugzeug nur mit hecklastiger Fluglage geflogen werden kann. i

I´m agree. But we need to scull in the same direction for move the ship forward. Nerfing enemy planes, or to add unnecessary difficulties, (such as; disabling friendly units icons in F10 map, causing unwanted team mates dispersion) don´t help to increase the population of WWII servers. ... Unless we have a proper radar vectoring system, by radio messages for fighters, as actually they had.

Yes, i can see that 1/8 of the P-51´s in that picture were P-51D. I still don't see the reason to disable the MW-50 of the K-4, and nothing in the P-51D, or Spitfire Mk-IX.

And yes!, all of us are agree in this. ..but as occurred before in here in DCS WWII, and IL2-GB servers, people finally could start asking why the server is empty of enemy pilots. As @Jafferson said "we can only use te stuff we got right now" Precisely ZERO P-51D´s flew over Normady the D-day, the totally of Mustangs in Overlord Operation were P-51B and C. correcting myself about i said before. First pair of P-51D´s were delivered in Europe in july 1944. They were two Ex-USAAF airframes, re-named MUSTANG IV operated by RAF A&AEE a Test unit. The two aircraft were given the RAF serial numbers TK586 and TK589, both serving only at Boscombe Dcwn until they were struck off charge in 1946 and early 1947 respectively. An order was eventually placed for 874 aircraft, the first of which were delivered in September 1944. I.A.W the book; Haynes, North American P-51 Mustang Owners' Workshop Manual First 75 Bf-109K4´s were delivered to JG77 fighter group for traning purposes in the second half of August 1944, at Neuruppin air base (north of Berlin) The first combat engagement of Bf 109K-4s with an enemy, took place on November 2, 1944, against a formation of 1174 bombers set out for the heart of Germany to raid petrol industry in Gelsenkirchen, Castrop-Rauxel and Leuna. I.A.W. the book MESSERSCHMITT BF-109K by Janda & Poruba - JAPO PUBLISHING - This mean there were not P-51D´s, and no were K4´s, in real "operation Overlord",.. so what kind of historic accuracy do we want?.

As far as i know, the P-51D had not enter in service in Europe at june 6th of 1944, (D-day), moreover, 2/3 of Spitfires in service were Mk-V. So to disable the MW-50 system of the Bf-109K4's arguing "historical accuracy" is only a ugly lack of sportsmanship,

Soo, remove the P-51D who did'n enter in service in Europe until March of 1944, when Bf-109 G6ASM, G-10, and K-4 were deploying.

You are right,... and it was confirmed by Volker Bau a test pilot of Flugmuseum Messerschmitt.

So we will have only a third of P-47´s with ADI (Anti-detonant water-Methanol injection) too??

This evening, i´ve engaged in combat with a P-51, (4YA WWII server) over french coast at about 8.000 metres. I start doing a spiral dive at 300 to 350 km/h IAS pursuing the P-51. My k-4 opened the slats, and start to wobbling side to side with no sense. It seem a new absurd stall behavior, because it is very know that automatic slats, remain closed in dives and negative G's manoeuvres I've never feel wobling in spiral dive before, in this game or Il 2-GB flying a Bf-109, soo i supose that the K4 flight model was "re-twiked" again.

By the way, after last month patch, i have noticed that Bf-109K4 only have enough controls authority over 250 kph, and it is easy to land without flaps at 300 kph than with full flaps at 180kph as actually must be done. Due to the K4 take off like a kite, if you set NEUTRAL trim (zero position), and the reason is tabu in this forum. It is more easy to take off the K4 in this game, without flaps and with FULL nose-down trim. (Any resemblance with the behavior a real Bf-109 is pure coincidence). For making the things worse, the tail-wheel have not enought grip, (even with tailwheel locked) and it have the same behavior in game, than a wood block dragging in the runway. I think that we have same problem with tailwheel grip in all DCS tail dagger warbirds, even the Mosquito. ..and please, correct me if I'm wrong.

I ´ve Windows 7 Home Premium SP-1, in Spanish, in my computer from 2011 with a about 1Tb of software CAD-CAM, Graphic edition, etc. I usually run DCS on STEAM with "BETA versions" option activated. After two weeks without using it, two days ago i start DCSW on steam and it updated automatically, but game don´t started, it show a error window, with a messge about "missing file api-ms-win-downlevel-kernel32-l2-1-0.dll" I went to this forum for search info, a them i read about end of Windows 7 support in DCSW after versión 2.7 released. ..But STEAM said nothing about this issue. I've tried to download and paste the missing DLL in game folder, but game shown other different error message, and i reverted the BETA option in STEAM, to game normal 2.5 version.

the installation of win 10 losing my today software configurations and keys would be my ultimate option, ... next year in a new machine perhaps.
