Hud tape Footage of Greek f16 block 52+ with CFT's fully loaded, two external tanks LANTIRN pod . 4 degrees AOA in bank level flight showing it can achieve ~ speed 377 with rpm around 95% almost like your tape. Indeed DCS loads are too draggy IMO. There are other segments in the video to get a general response Idea.

Some AOA in slow speeds level flight is normal and expected. At 300-330 kn CAS I see in track I would expect more of a 3-4degree AOA max, with these loads. Also don't forget that at very high speeds >400 kn CAS F-16 controls become very sensitive to the slightest stick deflection, something which is not very good depicted in this sim. What ED should do, is have some staff have go at an expensive CAE simulator, record and extract data through various tests, then try to match their sim to that. Instead they are using diagrams basing their models to that data and correct with CFD calculations. This however, will not always lead to normal correct responses. Also, interviewing real pilots can and will lead to different opinions about how the aircraft flies. A different approach is needed if they want to have a better derived flight model.

I have flown the Lockheed Martin Viper Simulator setupe'd with 2 external fuel tanks . I don't remember 7 degrees AOA level flight in any speed range especially in the low range. Personally, I think the whole DCS FM handling is very different in a weird way. BMS FM approach is more preferable to me but still doesn't quite hit the spot, it's stick feedback is also rather vague. On the other hand, these are the best and only Viper representations available to consumers we have. For this reason, I am gratefull and my criticism is aimed in a constructive manner.

Does anyone know if they messed with flcs too . Now the curves that I had applied feel very sluggish. -

Do you mind sharing how much you paid for it? -

@Yo-YoWhat exactly does this diagram tell us? I am sorry but I don't speak russian. For example what coefficient is CyMb and what Cx?
-
Ok great catch @=OPS=Slider @mvsgas! I start the stopwatch now ED. The stopwatch doesn't lie.

@ShalomarThe DCS Huey FM is not perfect. People who say it is, dont know what they are talking about... Look here for my report/post where few weeks ago I had two real life pilots have a go on it and what they had to say . Also this FM effect you mention has been discussed before years ago by @Hueyman pilot irl along with some other inaccuracies of the Huey module here: look at the bottom of the post for Flight dynamics comment. No matter of this post, no changes will be implemented by the developers, expect nothing. Even with data proof shown to ED nothing has improved all these years.

Edit : Now I realised there's another problem. for some reason I cant move the camera position left and right. it goes up and down but not left and right. also the tail rotor seems to be on the strong side. it doesnt require any left pedal input and at high speeds it;s efficiency is too strong it tilts the helicopter on the right side. Any files I can edit to fix that?
-
Thank you very much! @Tanuki44
-
Thats the thing its only the animation which is inversed . When I press left pedal i turn left but the pedals get depressed on the right side. If I invert axis it all wrong...
-
I have installed the mod but I have noticed that the anti torgue pedals animation is reversed i press left and it shows right. Its the second mod that I have this problem with (the other one was the bell47 mod) so maybe its something with my setup. Anyone else has this problem ? any solutions?
-
And the best video showcasing this is here : The Capetown fully restored Huey, in as close as possible Vietnam configuration. You can see the the ball fully centered and the pedals right offset in perfect level flight. Crabbing is not noticable at least not in dcs extend..
-
So you are basically saying that translating tendency is reversed as in more right pedal requires more bank? Maybe look for the bank angle in stationary, no crab flight at various speeds to confirm that. On the contrary, YOU have not researched enough before making claims . Look here for inputs by real pilots (even by Eagle Dynamics person who had a go), and control input diagrams (pbishop post page 2) before rushing to engage in "full dcs defend mode" even by questioning multiple videos. Its Crystal clear ZERO Sideslip Right pedal need. Crabbing has nothing to do with it.

Thanks for this post, and for using all the videos I have meticulously searched and posted about this issue. I have personally contacted many people over the years about this discrepancy but to no avail... . They consecutively doubted me, called me complete ignorant and that I don't know what I am talking about. They always kept insisting on the ground that since the UH-1H model is developed by SME's it is the seed of perfection. If only ED developers will stop flying kite and pay some attention at once...
-
Yes we tried some settings and settled with these : 2 deadzone curvature 10 (x and y axis) 0 deadzone full linear for the pedals. They said more curvature only makes the helicopter feel worse. We used a custom t16000 extended joystick and ch rudder pedals with some mods for smooth action.

Ok as I promised @Ironious, During the holidays I had 2 operators/ high rank militants, one former and one with 3600hours at the Hellenic Army UH-1H have a go in Dcs huey . I will keep their remarks short and in point, in a nutshell they said the flight model is ~80% like the real thing. They especially didn't like autorotations and said the rotor felt like a hog compared to the real thing. they also made some remarks about level flight speed and said dcs huey has a strange over tendency to return level when banking. They described it like the rotor is acting like a "gyroscope" to me. They also said vrs is a little exaggerated and that the huey in reality is not so prone. When they tried some aggressive maneuver flying, BOTH of them ended up with detached rotors (mast bumping) and laughed at how easy this is to happen... Also they said tail rotor is a tad on the weak side on max pedal deflection especially on the left . All in all, they liked some things FM wise, like tendency to roll with anti-torgue input, amount of required pedal input for hover etc... and very much loved the graphics. Some sound effects also seemed a little off to them. One of them also used to be battalion helicopter tester and has extensive knowledge of the huey , its capabilities and its complete flight envelope. He pointed me to this video tape where he was flying some tests couple years ago . he said its a good example to understand how the helicopter performs in reality. The video has poor quality but after watching it, Its really enlightening as to what one can expect. Especially 2:11 and 4:05 (max left turn rate) Enjoy

2: The flight model doesn't have this simulated properly. I had 2 operators/ high rank militants, one former and one with 3600hours on the Hellenic Army UH-1H have a go in Dcs huey.

https://en.wikipedia.org/wiki/Gravity_of_Earth Yes It will. If it will be significant enough to matter for a sim as dcs or to be even perceived by individuals is another story . Gravity is even affected by altitude so its even more perplex than common belief.
-
I just tried to explain how the slip indicator works.
-
There is no exact answer in this, It simply depends... consider not only gravity location but for example if you pull stick and raise g's. That for example will pin the ball down and will allow a small untrimmed condition while still being shown as fully centered
-
Nope not correct, Geographical location affects the ball, gravity in earth is not exactly same in all locations . The ball doesn't care about heading or track it just shows that all the forces are neutralized thus nothing is hindering efficiency. Think of sailing for example you loose the sails or take them in according to where the wind is coming from to maximise efficiency and gain speed but you dont necessarily have to change boat course. The ball is affected by centripetal acceleration that means a twisting action as seen from above top down view. It is possible to have a centered ball and still drift sideways but the heading will be maintained at least on theory (or in a flat earth). Nevertheless, the pictures tim has posted are no wind condition
-
This does not apply on the huey. the mast is 90 degree perpendicular to the tail rotor. The kiowa on the other hand has the rotor mast 5 degrees down left angled The slip indicator works according to gravity and centripetal acceleration. That means it will be affected by direct position in relation to ground... but since dcs doesnt even model earth curvature I am pretty sure the slip indicator is a simple wrongly implemented script.
