@pauld Okay, first point - when we developed this, it WAS fully tested on both FSX and P3D, my comment was purely that I no longer have FSX on my system to be able to check if there are any handling differences between the two sims with the same files (which has happened on occasion).
Second, and the main, point:
I have just got home and opened up my VC10 installation in P3D.
In ALL cases (Pro, Super, C1K, K3,K4) elevator_trim_effectiveness = 1.0
Pitch MOI for the K3, K4 and Super is 5057867.1
Pitch MOI for the Pro is 3198905.4
Pitch MOI for the C1K is 4050015.9These figures are probably in the ballpark for where you think they should be, and are certainly nowhere near the figures you quote.
Apologies if my initial response seemed defensive, but without the actual files in front of me it was difficult to be precise. However, I can now say categorically that there is something wrong with your VC10 installation, I'd recommend a re-install and if that fails we'll look at other ways to fix your problem.
@delta558 No apology necessary, no one likes to hear criticism of their products and clearly with the figures you state in place there would be no problem at all. It is strange that this has happened but to double check I have re-downloaded the installer and re-ran it and it is definitely installing with the incorrect values that I mentioned above.
The version that I have does not have all the different models that you list, it just has one model (the 1101) with several different liveries. It was purchased and downloaded from SimShack https://www.simshack.net/products/vc10-jetliner-fsx-p3d-1540 so possibly they have an incorrect or outdated installer on their website? The installer file is named "JustFlight_VC10_TP_140.exe" and has a version number of 7.1.100.1248 if this is of any help.
@Derek I can assure you that if you had attempted to fly the model I downloaded and installed you would find that atrocious is not in any way inaccurate.

@pauld Likewise, I can assure you that if we sold a product that was that bad we'd have heard about it by now - as would Google. As Paul says, it sounds very much like you have a duff copy - although I guess other Simshack customers would also have the same issues?
We will check their build out and see if that can clarify things.

Just to check something here, are you all comparing the same product?
The user is talking about VC10 Jetliner. The replies aren't referring and talking about the VC10 Professional are they?
Just checking...

@voice-of-reason I can't remember that far back
, but I would be surprised if there was such a large scale change on both fronts mentioned. The professional was developed directly onwards from the original. Not saying it didn't happen, but that's quite a massive set of differences - if it is the case that that is the state of the jetliner file, I'd suggest it would be best to provide a very late update to it!Just Flight FDE developer

@delta558 Odd that no-one has noticed up to now - given how many of the JL version were sold?

@delta558 said in Flight Dynamics:
@derek Yep, which is partly why I'd be surprised if it was the original file . . .
As per my previous post the product was installed from the installer I purchased and downloaded from SimShack https://www.simshack.net/products/vc10-jetliner-fsx-p3d-1540
If this is not an "original file" I would be interested to know exactly what it is that I have been sold?

As discussed earlier, it looks like you probably have the Jetliner version, not the Pro. There are most likely different flight models as we didn't do the development work on the Jetliner, that was from Aeroplane Heaven. If you get in touch with JF support they can probably sort you with our flight model to try - although, as I say, the Jetliner seemed to work fine if reviews and sales are anything to go by.

I am fully aware of which version I have, I stated which version it was in my original post and linked to the website where it was purchased from which also shows which version it is. As the product was sold as a JustFlight product I assumed (apparently incorrectly) that it had been developed by yourselves and that the JustFlight forum would be the appropriate place to post about issues with the product.
There is no need for any technical support, I have solved the issue myself by putting the correct values into the aircraft.cfg file.
My reasons for posting about this issue were that I thought (again apparently incorrectly) that JustFlight might be interested to know about this and would be keen to look into the issue and correct it, after all it is a simple fix that involves changing a couple of lines in the config file. The replies I have received on this forum have almost all been defensive or disbelieving of what I was saying and it would appear that no one has actually taken the time to look at the product or check the config file to see if there is problem so clearly it has been a waste of my time posting here.
I have nothing more to add and will not waste any more of my time on this.

OK - glad you have resolved it for yourself, but, as with all issues with our products (or those we publish and sell) your best bet is always to contact Just Flight support. The forum is really only there for discussion and we can't provide any proper technical support here.

@pauld I've just looked at my L1011 aircraft.cfg and the empty_weight_pitch_MOI= 12000000.000 and the elevator_effectiveness=1.240 so it seems strange the figures you get. I never make changes like this so I don't screw everything up so they must be original from the install.
