[QUOTE=LoBiSoMeM;331354]Launch FMB and set some strong wind flow. Watch your plane turning until face the wind...

But, PLEASE, use some accurate tool to send us proof of that: Cliffs Of Dover have winds...

As one said earlier: it's not a bug, it's the wind... :cool:

Ace of Aces is correct. It is more than the wind. If it is, there should be chocks in place. The aircraft always starts to turn even before starting up - even if it is sheltered in by a sandbag pit. At startup, the prop is not even rich or lean, the oil in the prop hasn't warmed up enough to allow the prop to take a bite of the air until after a few minutes of warm up.

I think it is a bug!

Agree with you, propwash effect should be stronger in CoD, maybe stronger than the RoF one, because of powerful engines and propellers... And I say that comparing to real life, not just comparing a simulator with another.

Once I stood behind a B-25 taxiing in an airshow, it was about 30 meters away and I almost fell to the ground (minute 2:20):

No propwash at startup. The prop can't be adjusted fine or coarse until it warms up. The prop appears to be in a feathered position until it responds to the coarse or fine controls after about 3-5 minutes of warmup. Then the propwash starts to work.

Just apply brakes and the "bug" goes away...

You do not understand: wind act pushing the side of the aircraft. The barriers to block wind don't exists in simulated CloD physical world, neither "chocks in" state like IL-2 1946, I guess. So, when you start mission in strong cross wind, your light plane will start to spin. Normal.

Next time I am going to watch and see if the grass is blowing, and to see if the plane stops spinning once facing the wind..

Cause I seem to remember the plane turning 360+ degrees..

Guess if thats the case, it is a bug.. If not, it's the wind..

True, that's the typical behaviour of a taildragger plane; it faces to the wind. I fly a CAP10 in reality and behaves like that, I can assure it! :)

You csan see what happens by wind here:

At 5:30 I receive a windgust from the left and plane goes in that way. It's not torque, I had already pushed right rudder, so I had to push more.

I would be ok ok ok dude shut up. Help me out here my hand is hot. I got a 6 pack in the cooler behind my seat. Make yourself useful.

Short pathetic video i made now:

10 m/s wind. All Ok here with winds. I'll test if some bug accurs that makes plane spins + 360º.

I think you don't understand. These are not planes made of paper, they have weight and friction on the wheels when stationary. Yes, it may well be the wind that is spinning the planes but the fact that the wind is spinning the plans while stationary has to be a bug. Maybe somthing like the wheels have no friction in reverse, that would probably do it. Edit: scratch that, of course youd end up being blown backward on the ground at stupid speed lol.

No, it's not a bug. Just maybe overmodeled, but one Spitfire has a rotating tailwheel and a big vertical stabilizer, and it's not an 747.

And - please - look:

Respect winds, please! :-D

If something is overmodeled in a sim it can be called a bug.

Agreed..

The coefficient of friction seems to be too low..

That is why this bug seems so odd.. In that it kind of acts like wind.. but it kind of doesn't either..

I mean sure in high winds I would expect the spit to move..

If the tires are aired up to max and it was sitting on a slick cement runway..

But in a grass field?

Something just does not feel right about that
