FGear Vehicle Physics (v1.4)

Hi, another questions…

  1. I noticed there is a 4wd suv - can this 4wd be tailored to using differential lock ie each wheel rotates at different speed depending on the terrain? Or if it is not there, is it easy for me (I am c++ programmer) to tailor one eg create a c++ class deriving from a wheel class? (I have not looked at the documentation in great detail).
  2. Can it create an 8 wheel vehicle? 8wd? How about custom turning like a tank transporter that turns its back wheels differently then the forward wheels?

Thank you.
