Why does my spit spin around before engine start..?

Spit not. Anyway it should work if that rotation is the plane facing to wind.

And no, it's not a bug.

Spits do have differential brakes.

If you apply brakes via axis you can release brake on one wheel using rudder.

Ageed, wind,not a bug.
Does the tail wheel lock on these planes? Got to find out.

When you have a plane with the wind blowing from the side it will act like a weathercock (if that's the right word) because of all the wind against the rudder the aircraft will turn into the wind.

But if you start the engine wouldn't the prop wash be much stronger than the wind? In ROF the propwash is modeled nicely so you can lift the tail from the ground while you are standing still when you have full throttle selected. And when you land and you're going the wrong way you can make the rudder more effective when you turn the engine back on.

I have stood behind prop aircraft in real life, and the prop wash is really strong. even with pretty 'weak' engines (engine of a glider (ash25mi) probably has something like 45hp)

Never mind about the breaks for a moment..

Let's assume for a moment that it is the wind that is causing the Spit to sit-n-spin

Ok, so far so good..

Than.. why doenst the Bf-109 sit-n-spin?

Or any other plane for that matter

What is special about the Spit?

Your 109 doesnt? Cos here it does for sure.

Yours does?

Ok dissregard than..

Ill admit I have not flown the 109 as much as the Spit.. but the few times I have it did not sit-n-spin like the spit does

I cant say always, cos i was not paying attention, but very often is accurate.
I am watching this thread with interest because I am not sure if it is the wind or not (tho I admit it is a valid explanation so far): if I recall correctly my 109 always spins counterclockwise, and that is what makes me doubt.

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.

I was not talking about startup. In the video there are cuts, so I assume the plane started to taxi after warming up, but not in real time of the video.

Just see the 2:30 minute and you'll see that. When the B25 shows me its back, after a couple of secons I receive the propwash, it is clearly heard, and as I said, its force almost throw me to the ground.
