@stuart666 My point is that, let say A-8 critical alt for 1.42 ATA is 22k ft, if we get 1.56/1.65 ATA Anton it will have exactly the same ATA at that alt. So if you would fight in Anton up high (above 24k ft as example), it does not matter if it is 1.42 ATA version or 1.56/1.65 ATA version. This is only thing what i try to say. Same apply to allied planes, 72" P-51 can hold that boost to lower alt then 67" P-51 and above blowers crit alt both will perform exactly the same, at 28k ft 130 P-51 and 150 P-51 will fly exactly the same no gains there from having 150 octane fuel.
-
Thing is that increased ratings for A8 won't improve performance across all alt. It only allow engines to be operated at increased ATA at alt where supercharger can actually provide that boost, same with 150 octane fuel for allied planes.
-
I totally agree that we should get A8 with increased power rating. Thing is that P-51D was one of first along with K-4 and D-9 which all of them are from similar period. Problem was created by introducing Normandy map which represents period 1-2 year before K-4 D-9 and P-51 D-30 which if i am not mistaken is 1945 Mustang model. Another issue is that ED decided to model early A8 production model with 1.42 ATA and not going for late version with 1.56/1.65 ATA along with 1943 Spitfire mkX which actually started its life as MKV and it was converted to mk IX in mid production, indication for this is shape of tail vertical stabilizer and rudder.

It is hard to test every gpu and every gpu driver, so yes in beta things like this may slip through. If this bug related to specific gpu than it is very easy to miss this bug.

I haven't experienced it too. I use DLAA too.

@stuart666 P-51 D is fast as hell, but idea alone that P-51 B/C is 20mph faster at alt above 13k is crazy and 13k of alt isn't crazy altitude where you won't fight in MP. And on top of that P-51 B/C were upgraded along with D model introduction. So overall B/C is no less competitive then D model.
-
B/C used 1650 -3 and -7 engines , -3 is rigged for high alt so it provide lower power output and lower top speed at SL but at alt between 13k to 17k makes B/C up to 20mph faster then D same at alt above 28k where B/C faster then D. British model of P-51B/C Mustang III when operated on 150 fuel was cleared for 25lbs boost which is 80inch in US planes made mustang III faster then any other US army P-51.
-
@stuart666 If ED would give us P-51 B/C version, that would be no good news for axis side, P-47 and P-51 in razor back version were faster then D variants with bouble canopy. B or C used same engine as D in P-51.
-
DCS P-51 does not have boost pump switch position EMERGENCY/NORMAL so they should not make any programming based on that particular manual in the first place.
-
I remember when P-47 or Fw-190 was coming out, we could see screenshots videos many many months before early access release, so when ED haven't posted any of those so far, i don't expect release at least 2 years from now, unless ED went in to incognito mode by not sharing any of the ww2 progress.

I stumbled on that "erroneous ignition timing " on this forum, and it was a bug , i can bring this famous Fw-190 Dora engine failure which took long time before it was fixed. Also this bug was killing Dora's engine after low power cruise.

@stuart666 This beeping sound so to warn pilot to lower landing gear and sound is activated if throttle is retarded far enough. As @Art-J siad, engines in mosquito are supercharged at high rpm supercharger output is very big and to get +7 boost you need little throttle opening and this triggers beeping sound, by reducing rpm to 2000 rpm supercharger output lowers significantly so to achieve +7 boost you need to open throttle almost all the way and this no longer triggers beeping sound. About sparkplug fouling, thing is modeled but it would require very long low power cruise to get in to it. The fastest way to foul spark plugs is idling engine for long time on the ground, this is why pretty much every manual advice to do magnetos checks before take off after long time spend on the taxi way, this could happen when large amounts of planes were taking off for mission at the same time. If you do 30 min cruise at 2000 rpm you don't need to worry about that, as manuals claims for precaution you should increase power every 30min of low power cruise, but to get in to severe sparkplug foul you would need to hold that low power for much much longer, trick is that if you do allow to happen and if one of cylinder stops firing there is no option to fix it in flight.

It appears to be the case, but why only K-4 other ww2 planes were equipped with ground adjustable tabs as well but we have no option to change those in game. So this aileron trim offset in K-4 has some historical background or this offset is random figure only just because we can change those trim tabs in special tab options?
-
Exactly. I went through all settings, like FFB etc turned them off, i set dead zones at 0. No double binds what so ever no other controllers connected only rudder pedals, joystick and throttle. This right stick deflection only depends on speed, it start to deflect at around 50kph and stops at 120-150 ish kph and stays that way in flight no matter you power setting or speed even if it is 700kph. Only way to made stick centered is to set aileron trim to -27 in special tab but why this is happening, i have no idea and this bothers me if i don't understand what is going on here Same as @razo+r everything off.
-
Axis binding checked couple times only single bind.
-
Engine torque or P-factor affect how plane flies but it can't deflect aileron. Rudder is used to cancel out most of unwanted effect of engine and prop but pilot is doing that via muscles or trim system. Prop planes slide slip or other effects, not because engine or prop deflect ailerons or elevator or rudder but because it has uneven thrust and you correct it with rudder to cancel out slip or other effects via control surfaces, trim system or build in angle of incidence of horizontal and vertical stabilizer. Beside prop wash can't affect ailerons, they are just too far from prop wash. In my case i have good rudder pedals and i can with ease keep ball centered but constantly keeping stick little deflection to the left is exhausting.
-
Thing is that aileron trim is not affected by speed or power at all. If i set aileron trim to 0 as default it will roll right all the time and deflection of aileron won't change at flying speed 200kph or 600kph same exact deflection, when i set -27 aileron trim it makes stick centered across all speeds, this is why i am curious about it. This is super weird for me because i would assume that if i set certain aileron trim it should change it's effects depends on speed. Anyway my solution is to set -27 aileron trim in special tabs then K-4 flies level when ball on slip indicator is centered. But still it bothers me because i don't know why this is happening, this right stick deflection appears even if you taxi K-4 with high speed, if you taxing with 50kph you start seeing stick deflect to the right super weird at so low speed.
-
DCS mention only something on not even forces acting on stick due to lack of elevator trim tab ? Is it what you had on mind. I can't find anything else.
-
I think that overheat is just aftermath of failure. Engine dies and then temps sky rocket happens.
-
Problem is in flight i have to constantly deflect stick to left or with rudder set slip worth whole ball in order to fly level. This problem is with me since i bought this module and only solution for this is to set up something like -27 aileron trim in special tab. I can't think a single reason why ailerons deflects it self as soon as 100khp is reached. right roll.trk
-
Can someone explain to me why as soon DCS K-4 get speed higher then 100kph stick deflect it self to the right making right aileron roll ? I just can't grasp it why this is happening, in special tab aileron trim is set to 0. I would be very happy if anyone help me understand this. No other DCS warbird has this characteristic.

@percivaldanvers If you have mw50 off you can reach 3250rpm with full throttle, deference is only in MP, w/o mw50 it is about 1.6 ata and with mw50 it is about 1.9-2.1 ata. w/o mw50 you can use 3250 rpm as long as 30min, if you engage mw50 this limit reduce to 3mins. Simple as that.

Actually alison powered p51 was performing better low to medium alt then merlin powered p51s, at high alt is where merlin shines.

It wasn't overlooked, they just copy paste code from P-51 module they just saved a lot of time by doing this. If it comes to real planes you can start up both p51 and spitfire both ways. Difference is in fuel pump on or off, if you start with fuel pump on you have to start with mixture lever in cut off position if not you will pour fuel on the ground. If you start with fuel pump off you can set mixture lever in run position prior, but ofc before you have to prime fuel lines with fuel pump before start up just like in spitfire.
