I've been working on creating an fde for a highly swept wing aircraft, and had a certain amount of directional wandering before a flick roll in the high-speed stall situation. When I installed the 1.08 update for Accufeel, this was (quite obviously) one of the items I was keen to look at and I feel that I should post what I have found as there seems to be some conflict:

I am no longer able to observe the effects I had created within the fde - the stability seems to override it. At 0 on the slider for stall stability, the aircraft has a large amount of stability so will not wander at all and can be pulled about very harshly without any adverse stall characteristics. At 100%, the instability is too much but the actual handling is also nowhere near what the fde has been set up to do - the Accufeel instability is there and seems to override any and all original stall characteristics. I have tested through the range of the slider, but am unable to get any of the quite distinct wandering that I originally had prior to the flick anywhere across the range.

I'm wondering if there is any way that we can have an option for this to be turned off, as the slider seems to have an effect (negative on this particular aircraft, and only because there was already a reasonably accurate effect in place originally) at all slider settings.

I can confirm that the fde hasn't been changed at all by the Accufeel module (just in case anybody was wondering) - I've uninstalled the update and gone back to the original version and the aircraft once again behaves as it was set up to do. While I had it installed, the extra sounds did sound rather good, so I'm hoping this can be resolved.

Cheers for now,
Paul.

Paul,

To determine if there is a conflict and where it is, first try disabling Accu-Feel for this aircraft in the in game menu and test. If there still seems to be a conflict, exit FSX and open your [FSX] / Modules folder and rename your two AccuFeel DLL's to something else, then restart FSX. This insures Accu-Feel is not running at all.

Report here what you find.

Scott.

Hi Scott,

Done that, just to clarify before going on to what you requested; there was no problem originally with V1 of accufeel, no problem with accufeel uninstalled (when I first uninstalled V1.08 I completely uninstalled Accufeel and tried fsx quickly to see if the effect was there) and having reinstalled V1 there is once more no problem. The only time I had a problem was with V1.08 installed.

I have temporarily re-installed V1.08 to follow your instructions regarding testing, results as follows:
With the aircraft selected 'on' in accufeel, the stability effects during the stall are altered in a negative manner.
With the aircraft selected 'off' in accufeel, the original, fde based characteristics are present.
I have already determined that with Accufeel not running at all there is no adverse effect - checked that at the uninstall point previously!

The problem as I see it is that, whereas with other effects there is the option to disable the effect by setting the slider to zero, for this effect you are making the presumption that fsx aircraft have a stable stall. This is unaffected at zero on the slider and all change is made by moving the slider towards the right (greater percentage). However, in this instance the aircraft already has an unstable stall effect and setting the slider to zero has the effect of stabilising it (unwanted). At higher percentages on the slider, the aircraft rolls more times as a result of the stall, but not as crisply as in the original fde and the original effect is lost. I have been unable to find a percentage point where the stall is unaffected in any way, and think that there should be perhaps a tick-box for this effect so that it can be turned off whilst leaving the rest of the effects active.

I'll have to leave it at that for tonight - 0400hrs start tomorrow is getting ever closer I'll be back around tomorrow afternoon GMT and will be able to test more then if required.

Thanks for your help so far,
Paul.

Paul, excellent, so it seems disabling the aircraft does in fact get rid of the conflict. This, btw, is not related to the stall stability slider, but rather to something else.

Can you PM me your contact info, maybe Skype or cell #? If we can, I'd like to really zero in on this and find out exactly what you are doing and what accufeel may be doing to conflict with it. I am confident we can nail this as long as I can reproduce this on my dev machine here.

Scott.

Someone should test this by stalling the Milviz T-38. That is a simulated airplane that has very wacky wing rocking behavior built into its native model when it stalls. So if it doesn't wag its wings when the effect is supposed to be turned off, then you will know that Accufeel is still overriding something it shouldn't be. I don't have that one installed anymore, so I can't try that myself, or otherwise I would.
