They have not answered the reason of delayed tail lift. and from my experience I believe their calculations don't result in correct outcome.

@DD_FenrirWell its quite similar despite common belief. They have comparable engines and layout. A tandem is also even more tail heavy it should be even worse... see the g-12 video I provided. A 40kmh difference is a big discrepancy Sure the elliptical wing of the spitfire is more efficient and provides more lift but the spit doesnt takeoff with flaps deployed..

@NineLine I am sorry but now you label my post as correct as is while its not. The g-12 video shows this. I am finding it very hard to believe you, as you just answer with a vague yes answer just to resolve the matter. Well it ain't gonna pass. There is a discrepancy but you just dont want to admit it. You remind me the Huey left pedal issue I have raised a couple months ago. It has been admitted even by you @Yo-Yo but nothing has still changed or improved..... Couple of months ago I build my own bf109 k-4 FM in X-planes plane maker from all the data I have collected over the years (correct control sizes throws airfoils Cg etc. as close to the real thing as possible) . I was not surprised it displayed different characteristics from dcs, that in my opinion resembled the real aircraft better. Such a trait is the left pedal need in high speeds which dcs completely lacks... Its sad... no respect is given in the community inputs... Its fine if you dont want to change cg but you should still give an option to the user to adjust it in his personal taste as others sims have...

@Yo-Yo What does this post exactly says about -3 -4 trim? Can you explain? It also doesn't explain the unrealistic high tail lift off speeds. It also doesnt answer my question if the prop has been modelled with 138kg mass inertia.

You can see the tandem g-12 which is supposed to be even more tail heavy than the k-4 raising tail in speeds less than 90kmh as in the timestamp I have provided. Exactly as I would expect in my experience... and must even has its guns removed @NineLine

Bf109 in game at 80~fuel raises tail at 120kmh with +1 trim and 20degrees flaps neutral stick. Any taildragger I have flown will raise from even ~40kmh no flaps neutral trim calm wind full fuel. I am not saying bf109 should raise tail at that speeds but 120kmh with such powerful engine points to that something is off. I would expect something to at least 100kmh The Cg might be perhaps correctly set but the MOI might not.

Its weight at the foremost aircraft station. not some slight radio addition in the back.

@DD_Fenrir Tell me, from your photo seems like you have taken a ride with the spit at Biggin Hill. Do you happen to remember At what speed does the spitfire tail lift during takeoff? Now compare with the DCS k-4...

These are simply negated by the fact that k-4 had the heavier MK-108 cannon and larger front wheels. No base in your claims .

I dont say that. There have been previous claims that the plane is modelled too tail heavy but the response from the developers was that this was due to the heavier k-4 wooden tail. I just mention that I recently found out that the prop weights 138kg from a trusted friend I have at a restoration project and I am asking if the developers are aware of this. @razo+r Go away you are not welcome here

I have some taildragger hours and I can say an experienced operator would almost instantanouesly realize that CG tends to be more aft happy from the prolonged tail rise delay which K-4 in dcs exhibits. This is at the default -1 trim 20degrees flap procedure. neutral stick even at 100kph will not raise the tail with 80% fuel load~

For starters you dont mention level flight nowhere on your post. Please go away find another thread to harass @razo+r Also No -3 doesnt keep the plane neutral with full flaps, Throttle idle @180kph

@razo+rBf109 lands at 200kph approach speed. 180kph minimum at most is the touch down speed which is the speed after being bleeded from flare... going to 160 170 would be too dangerous if not suicidal as it would result in limited control authority in reality... Also 20%is an ideal scenario. So No modelled FM is not good enough. That is according to the documented luftwaffe procedures which you should have known before replying.

???? I dont know if I really believe this, or you just trying to briefly terminate me prematurely... because the plane is really tail heavy. Currently -3 -4 trim, even with empty fuel load full flaps results in massive unrealistic nose up behavior yet it was the standard procedure german pilots used to land the plane. -3,-4 trim in dcs* is totally unusuable in any circumstance thus I am pretty sure something is not accounted for, or modelled correctly... PS: @NineLineyou tagged my thread as "investigating" are you indeed? because your reply considers the matter as never existent... Nevertheless, I dont expect things to change here they never do (As that requires Hard Work and Reavaluation!). Just dont consider customers as completely idiots that will never notice or bother with discrepancies being modelled in your products. *(its just a tad better in IL2 BOS but not good enough either)

@NineLine All I am asking is If the prop has been simulated with a 138kg mass. This is a very rare info and is very hard to find mentioned in documents but it is true. Of course I acknowledge that a change will result in other necessary "accomondation" acts, this is why if moving cg forward the brakes should be "nerfed". Even an option to set a small cg range by ourselves would be appreciated

Big mistake in my opinion, Big discrepancy from the real rotor. It must be corrected asap. I have noticed it myself in the past years but didn't make the effort to create a post as I have shelved the Mi-8 and don't play it anymore. Personally, such mistakes are what make me question more complex things like fm, and if they are modelled accurately . Which some people here will swear upon... Anyway, the repair will require graphics animation model correction, so don't expect for it to be resolved quickly. I would also like to mention that there are ton of other critical model inaccuracies also on the other belsimtek product , (as @Hueyman for example has reported in some excellent topics). They have been higlighted in repetition over the years but nothing has changed because the teams are always busy with the newest module. I think the community shouldn't be relaxed in such matters and we should always highlight our demand for such issues to not only be resolved, but be fixed fast. Otherwise we will be stucked in this neverending loop which is to maintain a holding pattern always waiting for the developers. Old modules need love and attention from the devs too and not being treated as completed work .

Please move cg slightly forward, this has been also discussed before. I know that the tail is wooden on the k-4 thus heavier if I am not mistaken also the fuel tank rests behind pilot, but this has been depicted heavily in dcs . I have read reports that most pilots landed the plane with -3-4 trim full flaps but doing this in dcs results in massive nose up behavior when landing in game. I am mentioning this because I just read on a rare source (and have not seen that anywhere else before) that the propeller on bf109 weighs a whopping 138kg! did the developers considered this when building fm? Now add prop cone, weapons and cannon, front fuselage reinforcements to accomondate engine, other front mounted subsystems etc.. and of course engine weight. I think all that would of course negate the slightly heavier tail... which has been so much overstated in past claims. Now I know that a small change would result In a need for other adjustments too, so I would also recommend a small brake nerf to balance this and maintain the full brake No nosedive characteristic as Erich Brunotte has mentioned and has been well implemented on the FM. A more forward cg will cause propstrike when braking! Nevertheless the brakes are slightly strong as of now. A small tweak would be greatly appreciated!

I am trying to figure out what is my system bottleneck and would like some more explanations on the built in counters. I know of the obvious parameters Fps etc... but what about the others? Specifically what is Cpu: Value is that Cpu frame Time?, Present, Obj, SunY, Update Main and Core are the things I am most interested in and would like some more info. Also Frame Time displayed refers to the gpu frametime or the cpu? Any info appreciated.

Update Guys: Its my GPU causing the stuttering. Tried with an other and 8350 plays totally fine, no more stuttering and thats even with a small supposed cpu bottleneck that vishera might have. Its also very strange because I could play MSFS fine with rx580 and medium settings. My guess is that Radeon drivers perhaps perform poor with DCS.

We want a Huey 2. That's all I have to say.

I know 8350 is obsolete for todays standards but it is above the minimum requirements. Also bulldozer is not as as bad as you say, back in its days it was a very decent processor though I agree single core performance is weak. I think the problem really lies in the lack of multicore optimization, which MSFS brought with SU5 and X-plane has with the Vulkan. It is also where traditionally AMD processors used to shine. As I said, I know I can upgrade for reasonable money, but I shouldn't have to in the first place. I wanted to hold out until ddr5 is a thing (and buy top of the line system rather, than get a mediocre one now) as I can still play reasonably most of the current titles. I guess I must wait until vulkan optimization comes to DCS as well. As for the msfs you mentioned. I run medium high settings and its smooth as silk 45+fps... X-plane: 60+ with vulkan (though its almost unplayable with opengl) good enough for me.

I tried setting affinity mask to cores 6-7 in task manager but I can still see all the cores are utilized which is weird. Stutters remain...

I run 500GB NVMe also. Pagefile should be ok. As I told you I can run MSFS with steady 50 fps no stutters at medium settings@impalor I really think its an amd issue. I am looking at this post but I am really confused on how to set affinity besides task manager, maybe someone more experienced can help

@Rudel_chwDidnt have an exclusion set up, Just added will try again and report back EDIT : nope still severe stutters
