Pitch "jerks"

@dopster198 as far as I am aware, they are aware of it and have seen the videos I supplied showing the problem with the aircraft. I doubt there is much more that can be done to bring it to their attention:
Personal opinion, I think the problem with the support is that they have not known what to do with the core flight model from the start - in one of the early pre-release videos Jorg mentioned that the FSX flight model was aerodynamically sound but had issues (forces all applying to one point). Unfortunately, there have been too many comments over the years critical of the tables / coefficients method, mainly from X-Plane users who are strong advocates of the blade element method. (Having worked with both, I will say that neither is perfect but both are far, far easier to work in than MSFS. Both actually make sense in their own way, which MSFS does not). Because of this, Asobo have started to shift away from where they started, effectively removing tables and coefficients and heading towards a geometry-based model. This has left us with a mixture of both though less and less of the former. But the geometry does not always get it right, in fact there are several points where it simply gets it very wrong. Mach Tuck, a straightforward aerodynamic effect which was controlled natively in the FSX/P3D sims via coefficients adjustable for speed (so you could precisely place the point and strength of the effect) does not exist in MSFS. That is just one of many examples. The coefficients we used to use to edge things in the right direction have been removed, and occasionally something new will be added into the mix (max angle scalars, the latest friction notes for ground handling just to give a couple of examples) which are not clearly described or actually make no sense aerodynamically.
It is a mess, a very big, unclear mess and there is a very small team trying to deal with all of the problems raised both in a customer-support role and a practical coding role. I asked a simple question on the dev support channel over a month ago - what do we do when the accurate, precise geometry gives totally incorrect behaviours? Still unanswered. I think they have tried to get a 'best of both worlds' flight model and ended up with something worse than any of the others. I don't envy them!
I'm aware that a lot of my posts these days come across as very negative, the flight model is all I have worked on in the various sims for the best part of twenty years so it is my primary focus. In ALL other aspects, MSFS has killed the competition, it is outstanding in the way it has brought the world to life. I start the game up, sit on the runway and look around in wonder still - yes, two years down the line I still get a sense of amazement at where they have got it to. There will always be room for improvement but as an out-of-the-box game, this is unrivalled. I just wish the core flight model had structure and knew what it wanted to be.

@delta558 try SP10 beta, now it's look like jerks looks better controlable, MS/Asobo bring some new friction commands and fluid options. Maybe will be easier to deal with this.
I think that each update of the SDK gives more possibilities, unfortunately you have to read it very well and make many attempts.
Especially when it comes to returning to the correct stall values and power / speed at given heights in accordance with the POH.
Do not abandon the Piper series please, it is still the best option currently on the GA market, with the exception of Milviz.
From a financial point of view, I also think that if you make a serious update that will work great, maybe you add more real functionalities like your own and correct load and weight model, fuel etc, there will be new and additional buyers.
You know perfectly well that a very well-made product will always sell and will always be competitive and worth your time.
Maybe this is also the moment where you can contact other studios by asking and solving problems together.

@sebastianr I have been on SP10 beta since it was released. Regarding the additions to the SDK, 'many attempts' as you say, because it is not aerodynamically sound. What we are having to do is guess what Asobo intended, occasionally helped by perhaps a single line of description.
Regarding the 'fluid' options, I spent a week implimenting the CFD lines on the PA38, adjusting them to see effects and with accurate geometry throughout. It removed all ability to stall and spin, along with several other issues. I know it is work in progress, but at the moment my view is that it is not the way to go. Their way appears to be to artificially increase angles (max angle scalars and "effective deflections", rather than accurate geometry and specific angles. Adding incidence and twist to ailerons at the stall - thus the stall /spin is even more artificial and not reliant on accurate geometry than it was in FSX!!)
I work with two dev studios and am in contact with others. I think it is telling that there appears to be a struggle to find people to work in this field.

Hey all,
I have done a single flight with the Arrow 3, Turbo Arrow 3 and Turbo Arrow 4 and so far the issue seems a LOT better, especialy on the Turbo's.
They still have the motion but the length of the pitch motion is severly shortened and toned down and atleast on these trips felt MUCH much better.
Can't say how happy i am to have my planes back in a state that does not induce headaches.Oh and on final, with the live weather it was fantastic on all 3 needles to see the IAS jump up and down like 10-20! kts in gusts and it felt so realistic jugling the controls and really working the throttle.

@cgnoorloos Ah, thanks for that.

Hi all,
A quick update - work continues on the flight model updates following the final release of SU11 and we are aiming to send a new test build to our kind volunteers (https://community.justflight.com/topic/3924/flight-model-updates/1) and testing team this week. If that goes well then we can proceed with releasing those.
Thanks again for your patience,

Just as an update...
I fly the Piper Warrior as a training aircraft, and I can't land this thing in the SIM.
From 1000-500 feet the nose is jerking up and down uncontrollably, then magically below 500 feet it smooths out perfectly.
Is this what people are talking about here? I really hope there is a fix for this.
-
I was working on a trim wheel device and a had a bug where it would get the wrong polarity and flip the trim from X up to X down or vice versa (via SimConnect). What I noticed when this happened was that the airplane itself changed pitch instantly and dramatically. So this could possibly be used as a repro case to help validate a solution.

Hi all,
We’ll shortly be sending a new FDE update to anyone that’s got in touch about helping us to test them. Please send me a DM if you’d like to get involved too.
Thanks,
MartynHi, what about this update???

Not going to lie, i love(ed) the Arrows, but the updates to these planes are downright glacial at this rate. And yes i have tested the updates and send feedback.
I am honestly getting quite tired of the waiting on updates on these planes. These are not cheap planes. I honestly believe we deserve to wait less then what, at least 8 months! , and going.I see al this news about incomming planes, but if the ones already out aren't updated in a reasonable amount of time i honestly won't buy those new planes. I won't live forever and waiting over half a year on an update is not alright.
-
Still waiting.....
I am getting tired of this. Safe to say i want them fixed but i will not be buying JF inhouse again.
I have never had to first complain a lot to even get it aknowledged, then help test as a paying customer and even then wait for creeping up to a year as blame was pointed to Asobo and now WT.Of all JF planes i own, only the 146 is working well and even that one fishtails like silly over mountains in live weather or nearly tips over on even some of the gentlest turns.

@cgnoorloos I'd suggest you take your frustrations out on Asobo - I currently have several unanswered questions which are flight-model specific on the DevSupport forum, some of them dating back almost a year and which have been bumped multiple times.
There appears to be little in the way of flight model support despite claims to the contrary, but plenty of changes implimented which we are supposed to just understand. It's almost as if they don't know the answers themselves.
Sorry for the short post, I have deleted multiple rewrites of it because they sound overly critical, but that's where we are at.

@delta558
Thanks for the reply. Sorry but that does not cut it. I buy the planes from you and not Asobo.
The other 3rd party planes i own do not have the problems the JF planes have. The C337 did have it for a while but has since been fixed.If other 3rd party devs can figure it out, then i don't think it is okey for you to just point a finger at Asobo. The F4U, Kodiak, Beachcraft, Fox 2, C337 and Islander to name my most other flown planes, they all fly well without the pitchjerk issue and they sure have had their fixes underway when needed.
Specially the Kodiak.Even the 146 fishtails a lot still. Something the DC-6 also did, and well, that one even as a bit of a backburner plane for PMDG is fixed, 146 as of yet, not so much.
Sorry but not sorry. I see a lot of talk about new planes, and i as a costommer feel those get the time and money while the already sold planes are just well, maybe worked on in lunch breaks. Not saying this is how it is, it is just what it feels like.
You could at least have pushed out some of the fixes we tested for you since some did positively affect the FM. But it's always "after the next update"
Kind of you to try and not be overly critical, but after a year of waiting i am being critical, i payed good money for planes that just don't get fixed, while others do.
