Well, I am giving it a shot, but it seems it won't be that easy. See my

Hi there,
The rest of this mail will just deal with the gear friction issue for now.
Having looked at Gear.cpp I think I can understand the issue a bit
better. The method that calculates tire friction is Gear::calcFriction.
It looks like this:
float Gear::calcFriction(float wgt, float v) //use

I'm just an absentee hacker, so I can't say what is or isn't
acceptable any more. But it seems like a sane enhancement
Hi Andy,
Thanks for that! So just to clarify -- this is a bug in Yasim code (or
more like a missing feature) and I'm welcome to fix it? :)

The plane gets pushed either forward or backwards by the wind, depending
on the wind direction. The prop seems to only get turned in the
direction of normal rotation, even in a tailwind, which seems wrong to me.
But really the main issue for me is that this amount of wind should not
move the ai
You mean when the wind is blowing from the front-left of the plane?

Technically, you also have the compression of the wheels -- when the
wheel turns, part of the tire in the front gets compressed while the
back gets uncompressed. This is also a friction loss. Plus there is some
friction between the rubber and the road.
But my point is that the amount of frictio
