V35 X-Plane Yaws Sitting on Ruwnay

I recently purchased the Carenado V35 for X-Plane. I thought it was odd that while sitting on runway with engine off the plane turns about it yaw axis to align with the wind, which was 18 knots at the time. This is very unrealistic as it wouldn't happen real world unless the winds were substantially higher than that. Parking brake is set to on.
I sent this same message to Carenado support and here was their response:
How high have you set the wind? This would be a behaviour dictated by the sim... possibly too low a lateral friction coefficient on the tires. This is not a parameter aircraft developers have control over, and it is a behaviour you'll find sim-wide, not just with the V35 or with a Carenado plane. This would be something to address with Laminar Research, de company that develops X-Plane.
Regards,
Daniel K.
The wind was set to real world environment and as I mention about it was 18 knots. Same thing happened with the default Cessna 172.
Is anyone else experiencing this issue?
Thanks,
John

Hello,
I also have tremendous pull to the left (always left) in xplane in any prop aircraft. The thing that I find weird is that when I counter the left turn with a right twist of my joystick the aircraft responds like I hit the brakes. So the only way out of the issue is going to like 50% throttle which seems to turn off nose wheel steering and everything works pretty smooth. I don't really know why this happens on all of my props, a higher throttle input actually relieves the left turn tendency and I know my controllers are all set up right. Some say there's a config file to delete and allow xplane to rebuild your settings to default but I just learned to kind of "gun it" to get beyond whatever prop torque/wheel steering issue I have.

I have found the same behavior with winds like that, in the default 172, powered off. It will tend to windmill into the wind but aileron and rudder will correct to some extent. There's a current beta for 10.45 that will fix a recently uncovered bug (but long standing) where prop plane torque effect was doubled.

I was flying on the network Saturday night to KGCN with the Carenado PC-12 and experienced the same wind-vaning effect. This is an X-Plane behavior that I have seen on default aircraft but it also carries over to 3rd party aircraft. Hopefully as X-Plane progresses some of these "bugs" will be corrected.

25kt crosswind can move a fully loaded Carenado Cessna 208 sideways even with park brake on. LES DC-3 does not move on gravel runway even if you have full throttle. Taxiing a taildragger with a 15kt crosswind is nearly impossible... The ground friction in X-Plane is nothing to brag about.
I've found two workarounds. The best one is DuctTape plugin from -bc-, which (among other things) can also turn off the wind if you are on ground. However it works only for aircraft which don't use the copy-protected SASL (you have to edit the aivonics.lua, which on copy-protected aircraft is illegal). The other solution can by FlyWithLua plugin, you can assign a key binding to manually turn off the wind.

I've found the same issue on the Cirrus SR20/22 I fly on X-plane. The plane tends to align with the wind even with low wind speeds. It becomes especially noticeable during takeoff with a right crosswind since I'm forced to use left rudder to keep the plane centered (with a left crosswind I'll have to use more right rudder but that feels "normal" since single engines have a left turning tendency anyway.
I thought this was a simulation error specific to the Cirrus. Sorta reassuring it happens across the board.
