angular damping having no effect

Hi guys

I'm trying to make a simple vehicle simulator that has rough, uneven terrain. The problem is that the physics are really finicky - whenever one of the wheels are off the ground, the the friction seems to go to nothing and the vehicle swings wildly. It controls fairly well when all wheels are on the ground - ie. on a perfectly flat surface.

I tried setting the angular damping to very high values, but it seems to have no effect...

I'm just using the simplevehicle class from the demo files, and steering by applying an off-center force. Is there a better way to make vehicles with ogre newt?

thanks for any tips.

well, I used setomega on the vehicle body to do damping, and it's working well so far.
