help with the physics etc

[arcanise]

greetings everyone, as many of you know there is a BZ3 in the makings "bionite origins" and I am on said project and right now we are trying diligently to mimics the movements and physics of the BZ1 vehicles as we feel BZ1 was much smoother and better built than BZ2, so i am here asking if anyone has any insight on how the vehicle controls worked in regards to physics and algorithms. thank you
