XP's flight model is rather detailled, as we know, and Austin is constantly fine tunning it.

Sometimes while trying to make it even more detailled, problems arise, just like the bug with some prop aircraft showing a rolling tendency which is counter-intuitive, and actually against what happens IRL.

But there's a reason for everything, and Austin already identified and solved that problem, and an upcoming release of Xp12 will fix it.

Meanwhile I found on this recent development video from IL2-Korea an interesting sequence where we can see a diagram of the lift and propwash as modelled in the WW2 prop aircraft, and in the future Korea War jet fighters.

Interesting to observe around 36:20 a diagram of lift distribution in a P51D and how it is affected by propwash, and there it is, just as in Xp12, you can glimpse the higher lift on the port wing, which in part ballances the left rolling tendencies.

Austin is doing it already since a long time to this part, but probably he just needed to fine tune the effect in itself so that in certain aircraft it doesn't become prominent and not only overcome, but actually counter the torque effect.

They're doing a Korea based IL-2 installment? Color me interested*!

 

(*If it comes with a dynamic campaign and without a DLC hell.)

Yep, they are.

Don't know about the DLC details yet...
