I tried the latest RC, but unfortunately...

.) ground physics, in the default C172, C90, B738 still not plausible to me;

.) we have that new anti-torque bug - I just hope it will not stay unsolved for as long as the old torque bug introduced when Austin decided to model prop torque effects along XP9...

.) I really can't say if aircraft behaviour under variable winds is due to the way XP calculates the weathervane effects on each aircraft model, or the way the wind vector is made variable in the weather engine - this can be overtaken by a good 3pd weather engine. Actually even the good-old NOAA plugin somehow takes care of the default wind vector calculation hysteresis ...

Other than that, it's a very beautiful and promissing alternative simulator...

I do appreciate all the hard work the Laminar team does in upgrading the sim, but a release note like this...

XPD-8519 Improvements to helicopter flight model.

... doesn't really tell us anything useful. It would sure be nice to know WHAT they improved in the flight model!

Ant-torque bug, do you mean the roll to the right bug that was fixed ?

That one strider, but as far as I can tell, it isn't fixed at all, at least on my tests with the default C172, Baron 58 and the C90...

All of the three still right roll at cruise or higher power settings :-(

I also didn't see any mention of it in the release notes.

In beta 7 something like this was mentioned as fixed bug: "XPD-8408 All prop aircraft with CW rotating props roll right inflight." Is this a different one? If so, is your observation reported already?

Thx Mario,

I didn't see that one, but indeed I reported it myself and it was assigned the code:XPD-8408

but the betas ( all ) since 7 didn't actually fix it - is still very present.

Emailed Austin about it yesterday and he told me - maybe for 10.20... this and a couple more issues...

Maybe refer to that bug number and write it again (maybe also to Ben), because if they _think_ they fixed it already, they might overlook it for 10.20 ;)

Mario, 

a friend pointed me to a Baron 58 mod available at the .ORG, freeware:

https://forums.x-plane.org/index.php?/files/file/39597-beechcraft-baron-58-double-trouble-hd-flight-model/

and decided to try it out. 

 

First I should point out that at least one aircraft I tested after this new propwash model was introduced didn't suffer from the right rolling tendencies, and always behaved rather plausibly, namely the VFlyteair Grumman AA5.

Now, this modified Baron 58, provided we turn it's aileron ground adjustable trim tab to 0.0158 up to but not exceeding 0.020, also behaves plausibly.

I noticed the author created the wings using as much wing "slices" as he could ( three WING1, 2, 3 + 3 Misc WING ) probably distributting the propwash effects in a way that ballances whatever causes the "new" right rolling tendencies on most aircraft with a CW-rotating prop ( correspondingly  left rolling tendencies for CCW rotating props... ).

Probably most aircraft require the same approach, redesigning the wings and other lift / drag generating surfaces  in order to create the proper interaction between these and the new propwas model calculations ( ? )

Jose,  multiple wings are mainly available to accommodate the wing and control surface shapes and sizes.  Having "more" doesn't automatically equate to "better".

Yes, but aparently when these fall in the propwash of an engine, being able to set them better proportioned does apparently play a role on the end effect of the new propwash model... At least this is the description available with that Baron 58 mod.

I am not seeing the roll to the right anymore on the takeoff climb or the cruise phase of flight in the 172. It will roll to the right or left slightly after a bit, but thats normal in my real world flying experience. The air is in constant motion like the ocean. If you are using a cheap plastic yolk that could be part of it.

I guess that has nothing to with the quality of the joystick. One just cannot expect to let go of your controller and fly in a straight line, not even in FSX. If you don't touch the controls for a minute, you'll probably enter into a pretty nasty turn. I guess that is normal (but I'm not real world pilot unfortunately). What wasn't normal is that during takeoff your aircraft wanted to weer off the runway unless you've apllied almost full rudder and had screetching tyres, almost drifting while trying to stay to keep the aircraft straight. And that has been fixed, at least on the Cessna, I don't know the others.

Far easier ti stear all planes now. Big improvement but still have to get that wind sorted out.

Unfortunately for me it's still there, very pronnounced on all of the default props, and certainly noticeable in the default C172.

Even setting the aileron trim tab to 0.000 ( it's set at 0.008 by default, thus causing a right rolling moment which was meant to counter pro effects ) and the engine side can to 00.0º ( it's set at 00.2º right by default also to overcome prop effects ), the right rolling moment is there as you start your climb at climb power.

The default Baron 58 is even worst but the mod whose link I posted above, provided the aileron trim tab is set to no higher than 0.018, will behave plausibly at any power settings, banking right only when the power is brought back for descent - but that's plausible too...

Ok I tried the default Baron and it is rolling to the right at cruise. I am not seeing the roll in the 172 for some reason.
